China's inverter started late, backward technology caused China's domestic inverter in the inverter market competition is at a disadvantage, not only the steel industry, rail transportation and other technical requirements of the very few domestic inverter industry rarely enter, even if some Technical requirements are not too high and some foreign brands preconceived segments of the industry is also very difficult to enter. China inverter market maintained a 25% -35% annual growth rate, the growth rate ranked first in the electrical industry. Far exceeding the level of China's GDP growth in recent years. It is expected that the average growth rate will remain above 25% for at least 10 years in the future. At present, the growth rate of inverter installation capacity (power) in China is actually about 20%. According to such growth rate, China's inverter market will not mature until the end of 15 years and gradually become saturated. In China, low-voltage inverter market, foreign brands still dominate. At the same time, the strength of China's inverter supporting industries is relatively weak. Domestic brands have a certain gap with foreign brands both in terms of technology, processing and manufacturing, industrial design, etc., in terms of financial strength. China's inverter started late, backward technology caused China's domestic inverter in the inverter market competition is at a disadvantage, not only the steel industry, rail transportation and other technical requirements of the very few domestic inverter industry rarely enter, even if some Technical requirements are not too high and some foreign brands preconceived segments of the industry is also very difficult to enter. Into the 21st century, the gradual rise of domestic inverter, is now gradually seize the high-end market. Shanghai and Shenzhen became the forefront of domestic inverter development, emerged like Huichuan inverter, INVT inverter, Ampang letter inverter, Europe inverter and a number of well-known domestic inverter. Which Ampang letter inverter was established in 1998, is one of the earliest manufacturers of frequency converter. More than a decade, Anbang letter to the rich cultural foundation as the cornerstone, supporting the growth of enterprises earlier passed TUV ISO9000 quality system certification, was awarded the state-level high-tech enterprises, for many years been rated as China's top ten users of domestic inverter Brand. High precision, wide range of frequency control to become the first choice for industrial speed At present, vector control is used in the fields of low-voltage frequency conversion and high-performance high-voltage frequency conversion. Compared with V / f control, vector control has obviously improved in speed control range and control precision. The level of industrial automation in our country still lags behind that in developed countries. The 12th Five-Year Plan proposes to transform and upgrade manufacturing industries. Among them, the development of advanced equipment and the promotion of manufacturing industries will become the direction to guide future development. Frequency conversion technology because of its excellent performance will be in the field of industrial speed control and precision control to be further promoted. Especially in the manufacturing industry, a wide range of low-voltage inverter technology, the future development of automation and equipment upgrades are closely related. As a whole, the competition in China's inverter industry will become increasingly fierce. As the market is very attractive, the potential capacity is very impressive. It has continuously attracted new players in the industry to enter. However, the existing market has already reached a certain scale, its development is gradually maturing, and future resource plunder and market war will be inevitable. With the continuous improvement of technology, the stability of product quality is gradually improved. With the advantages of service and price, the competitiveness of domestic manufacturers will be even stronger. From the demand side, the inverter is also gradually diversified, general-purpose, special-purpose products, are to meet the diverse needs of users. In addition, inverter manufacturers also pay more attention to product quality and safety, and actively seek greater breakthroughs, so that the inverter can work well in harsh environments and ensure safe operation and normal production of users. Tungsten Carbide Roll Rings, also known as hard alloy roller ring, has been widely used in the rolling production of high-speed wire, bar, threaded steel, seamless steel pipes, etc. due to its good wear resistance, high-temperature hardness, heat fatigue resistance, thermal conductivity, and high strength.

The Tungsten Carbide Roll Rings we produce mostly come in two series: WC Co and WC Co Ni Cr, with Co and Co Ni Cr as binders ranging from 6wt% to 30wt%. From a usage perspective, hard alloy rollers have good comprehensive mechanical properties, with a bending strength of over 2200 MPa and an impact toughness of (4-6) × At 10 ^ 6J/m ^ 2, the Rockwell hardness (HRA) can reach 78~90. During the high-speed wire rolling process, the single groove steel passing amount is much higher than that of cold hard cast iron or high-speed steel rollers.
China inverter market technology upgrade is imperative
