typically appear in tape slitting

Laser scanners are important to the steel fabrication process. Since the coils have not been slit, the edges of the coils are vulnerable to rolling defects and deficiencies corresponding to heavy skins, folding, scabs, crushing, scratches, etc.,Tin Plated Steel Sheet  and manual inspections have been intensified for the primary time on the steel plate. Strip bite edge (ie the strip edges jagged uneven phenomenon), typically appear in tape slitting, slitting machine disk causes is blunt or sharp edges precipitated.

That is accomplished by letting the water flow via a steel (usually chrome steel) tube or coil surrounded by an outer metallic tube or shell which is stuffed with hot engine exhaust (air). Ironing is a sheet metal working or sheet metallic forming course of. https://sesteelpipe.com/product/best-price-galvanized-rectangular-steel-pipe-supplier/ Due to the excessive technical performance of sizzling-rolled coil materials and production technology requirements, so the one hand, domestic manufacturers meet the requirements than the steel plate producer less the other hand, their production processes and quality degree to determine its market price can be higher than the warmth rolled metal sheet.

There is No Need to be Too Pessimistic about the US Economy in the Short Term (II)

The US stock market’s trend in 2019 also faces strong uncertainty. From a bearish point of view, the downward trend in economic growth and the improvement in corporate earnings on the fiscal deficit have basically ended, spiral steel pipe supplier which will aggravate the downward pressure on the US stock market. However, from the perspective of Lido, the suspension of the Fed’s monetary policy tightening and the decline in the valuation of the US stock market in 2018 may lead to the stabilization or even rise of the US stock market. However, as market participants generally expect positive progress in Sino-US trade negotiations, once the results of Sino-US trade negotiations are less than expected, this may lead to major adjustments in US stock markets and global stock markets.

First of all, although the world’s major economies have shown a pattern of collective growth in growth in 2019, they do not have to be too pessimistic about global growth in 2019. The US economic growth rate is expected to fall from 2.9% in 2018 to 2.2-2.3% in 2019. The economic growth rate in the euro zone is expected to fall from 1.9% in 2018 to 1.1-1.2% in 2019, but it is still not a recession. At present, the high-frequency indicators of the US economy show a relatively uncertain trend. The probability of a soft landing of the US economy is significantly higher than the probability of a hard landing. Secondly, the recent 10-year US Treasury yield has fallen below 2.4%, and the probability of further sharp decline is very low. After all, after nine interest rate hikes, the US federal funds rate has risen to 2.25-2.5%. Under the premise that the US economic growth rate is still higher than the potential growth rate, the inflation rate is still around 2%, the labor market is still tight, steel strip supplier and the Fed will not cut interest rates in the short term, the 10-year government bond yield is difficult to maintain the same as the overnight lending rate. Even lower than the latter. In the near future, the US 10-year bond yield has the possibility of bottoming out.

Although the end of the Fed rate hike cycle may lead to downward pressure on the US dollar index, considering that the euro zone’s economic slowdown is no less than that of the US, global financial market volatility may continue to rise, and the global economic growth rate will decline in 2019. The factors mean that the performance of the US dollar index will not be too bad. Considering the following two aspects, the exchange rate of the US dollar against the RMB in 2019 is expected to show a two-way wave dynamic potential around 6.6.

Whether it is the downturn in economic growth,Tin Plated Steel Sheet the decline in corporate earnings growth, the rise of domestic political uncertainty, and the intensification of global financial market turmoil, it may cause a new round of turmoil in US stocks. With the approaching of the new round of US elections in 2020, the negative impact of domestic political uncertainty on the stock market may gradually become prominent.

The Current Key Point in China is to Improve the Innovative Education Quality (II)

The reason is that this is due to the fact that a considerable proportion of university graduates in China have completed STEM subjects (up to 40% in 2013), while the United States, the United Kingdom, Germany and other developed countries are less than one-third.

Despite decades of outstanding achievements in the reform and development of higher education, compared with many higher education powers, the problem of ”big but not strong” in China’s university system is still very prominent. The World Competitiveness Yearbook (2017-2018) shows that although China’s national competitiveness ranking is 27th and the innovation index is 28th, the higher education index ranks only 47th. There is a significant gap compared with developed countries such as the United States (No.3), Germany (No.15), the United Kingdom (No.20) and Japan (No.23). From the perspective of the needs of economic and social transformation, the types, levels and professional structure of talent training in Chinese universities are not consistent with social needs. On the one hand, the ”top-of-the-ground” structure of the talent team has not yet been formed. Not only the number of high-end talents such as science and technology leading talents and innovative entrepreneurs is relatively insufficient, but the scale of industrial high-skilled talents is also very limited. On the other hand, the problem of employment difficulties for recent college graduates has intensified. According to the World Bank study (2018), in 2015, the unemployment rate of Chinese university graduates (within six months of graduation) was about 8%, 25% of graduates were paid less than the average wage of migrant workers, and 30% of occupational types were low-skilled ( No university diploma is required). stainless steel pipe suppliers To a certain extent, this reflects the downward trend of the return on university education in China. The reason is that the improvement of the quality of education has not been synchronized with the expansion of scale, especially the cultivation of students’ awareness of innovation. China’s higher education is still in the “extended” development stage, and the intensional development of innovative education is insufficient.

The transfer of educational methods is lag and the insufficient of innovational talent cultivation are become the key shortcomings.

Firstly, the teaching methods of education are backward, and the evaluation methods of students are single.

On the one hand, the development of practical and interactive teaching is insufficient. Classroom teaching is still based on knowledge indoctrination, and it emphasizes knowledge learning rather than exploratory learning. The teaching methods of most colleges are still based on lectures. The environment of students’ self-experience, self-learning, and free creation is not yet available. Practice teaching has also been weakened to varying degrees. Students have more passive practice components and too few active practical components. Teaching methods overemphasize knowledge transfer and knowledge memory, and do not focus on methodology and creativity. On the other hand, the student assessment method is single, focusing on results and light processes. Most of the assessment contents are uniform, not only lacking the multi-chemistry industry assessment content system with equal ability and knowledge assessment, but also the evaluation method is relatively simple. The monitoring, evaluation and feedback mechanism for the student learning process has not been established.


The Exploitation of Space Solar Energy, China Quietly Walked in front of the United States

The US media said that China plans to launch solar power activities abandoned by NASA decades ago in space, which puts China ahead of the United States.

According to the US Consumer News and Business Channel reported on March 17, John Mankins, in his 25 years at NASA and the California Institute of Technology’s Jet Propulsion Laboratory, presented several ideas for expanding the use of space solar energy.galvanized steel tubing suppliers These include solar-powered interplanetary vehicles and space-based power generation systems. In the 1990s and early 2000s, Mankins paid particular attention to the second idea when he served in senior research positions at NASA. He was responsible for determining whether there was a way to transport electricity from space to Earth. This idea has the potential to fundamentally change the business philosophy of the power industry–and allow any world power that does this first to gain control of the field on a global scale.

According to the report, Mankins almost saw this idea become a reality, but for various reasons, the plan has never officially started. Therefore, when there is news recently that the idea that NASA gave up decades ago is now revived by the government, people have reason to be excited. But it is not NASA, but China,square steel tubing for sale  that ultimately supports this idea. The report said that the concept is likely to regain attention as China recently announced that it will complete the high-voltage transmission and wireless energy transmission tests required for space-based solar power systems in the next decade. At present, space is becoming more and more important to the world’s major powers. The Trump administration officially confirmed the plan for the US military to set up a space army in February this year.

According to the report, the solar power plant plan that China is considering to build includes the construction of small and medium-sized stratospheric solar power plants from 2021 to 2025 and the power generation; after 2025, large-scale space solar power plant systems will be started. According to the recommendations of the relevant expert group, China is striving to complete the space ultra-high voltage power transmission and wireless energy transmission test verification in the next ten years, and realize the construction of the megawatt space solar power test station in 2030 and the construction of the Jiwa class before 2050. Medium and long-term goals for the capacity of commercial space solar power plants. Mankins said: “The explicit interest expressed by the Chinese side will greatly stimulate the interest of the parties in this field. About 10 years ago, the Chinese began to seriously study this issue, and then they started participating in the international conference about 5 years ago. Today, they talk about this issue more openly.”steel coil manufacturers

Space-based solar power plants will capture the intensity of solar energy that would never be captured on Earth, and then use the laser beam to transmit energy back to Earth to meet energy needs. China said in a recent statement on the project that a major advantage of space-based solar power is its ability to continuously provide a stronger energy supply than solar power plants on Earth.

The Knowledge about Mexico’s Ancient Civilization(II)


The Teotihuacan civilization began in the first 200 years or so.Mini electric scooter manufacturer It was born after the demise of the Olmec civilization, about the ancient Indian civilization at the same time as the Maya civilization. However, unlike other ancient Indian civilizations, the context of the pedigree is relatively clear. The origin of the Teotihuacan is still a puzzle that has not yet been clarified, and no one can confirm that the civilization once had text. And leave a record of the information. Today we know the existence of this civilization, except that they have left a huge legacy for analysis, and some other surrounding civilizations in their contemporaries mentioned Teotihuacan in the classics or paintings. Things are also the key to another reference. The Teotihuacan did not use this name to refer to themselves. The name was the demise of the civilization, and the subsequent civilizations of the Teotihuacans who existed in this area were used to refer to their predecessors in the Nahuatl language they used. Refers to “the land where the gods made people.” Although in the Aztec era of the Toltec and even later, the ancient civilization has long since disappeared, but they still regard the ancient city where the Teotihuacan once lived as a holy place, and therefore there will be Such a title.Mini electric scooter supplier

The Teotihuacans appeared in the central plateau of Mexico in the first 200 years, and built a city with a population of about 50,000 between 1 and 150 years. It is the earliest city-level settlement in the entire America. During this period, they established a primary-scale city centered on the “Dead Road” in the north-south direction.electric scooter for Adult The buildings are mainly composed of pyramids and temples. After that, the city gradually grows and the buildings used by various civilians are also completed. The development of the entire city and civilization reached its peak in 600 years, when the population of Teotihua Cannes might be between 100,000 and 200,000. It has cultural achievements such as huge architecture and exquisite murals, but it has disappeared between 650 and 750 for unknown reasons and finally disappeared.
