Performance Advantage
1.Used modified high manganese steel and Ultra-high manganese steel. It has enough resistance to impact toughness.
2.Optimized heat treatment process, so the product is high hardness, strong wear-resisting, long service life.
3.Big crushing ratio, high crushing efficiency
4.Cost-effective, easy to disassemble.
High Mn is usually used as the material of liner board. The board working condition is compressive stress, takes the advantage of high manganese steel hardening properties. When high manganese steel is under high impact force, it can produce a hardening layer on the surface. After it is wear and tear, the material will continue to produce new hardening of the surface layer. Wear-resisting performance of high Mn is good. Since the high manganese steel yield strength is low, for strong abrasive materials, it is often wear and tear before hardening.Such as iron ore and stone crushing, high Mn wear resistant performance is low.
How to improve the service life of the liner board, and to make the performance of high manganese steel hardening. It is a common concern of customer and manufacture. Our technician join chromium, vanadium, titanium, boron and other rare metal elements in the casting process, effectively improve the microstructure and mechanical properties of high manganese steel.Compared with similar products, our liner board`s comprehensive performance is good. The wear resistance performance of alloying of high manganese steel liner board is much better than normal high manganese steel liner board.

When the deputy secretary of the provincial party committee, the provincial party committee secretary Gan Daoming and the deputy governor Wang Huaicin split the red silk, all eyes fell on the two silver-gray polysilicon rods. At this moment, the people present were ups and downs --- China finally succeeded in mastering the production technology of thousands of tons of polysilicon and became a member of the world polysilicon production club.
Three days ago, at 6 pm on February 26, Xinguang Silicon, controlled by Sichuan Investment Group, successfully produced the first furnace polysilicon. The total weight of polycrystalline silicon was 615.3 kg and the maximum growth diameter was 100 mm. After rigorous testing, the product quality has reached the national standard electronic grade second-class product level, which is superior to the foreign polysilicon factory to supply China's solar battery material quality level.
"Siam Dream" came true, and this day is hard to come by. Zhang Huiguo, the 68-year-old chief engineer of Xinguang Silicon Industry Co., knows the vicissitudes of life: the large-scale polysilicon production technology has been monopolized by the top ten factories of the seven major companies such as Germany, Germany and Japan, as the national first high-tech industrialization demonstration project. The 1,000-ton polysilicon project has undergone several shareholder changes and technical route adjustments during the implementation process. With the support of many parties, based on China's many years of research results, Xinguang Silicon has successfully overcome one technical difficulty and succeeded in breaking the Western technology blockade for more than five years.
"This is a major development and a major breakthrough. It is of great significance to the implementation of the province's strong provincial strategy and the realization of a large industrial province to a strong industrial province. It will be important for China to promote independent innovation and develop large-scale polysilicon production capacity. Impact.†Gan Daoming pointed out that the success of the project commissioning test is only a phased result, and there is still a certain distance from the mass production target. He said that the provincial party committee and the provincial government will continue to support Xinguang Silicon Industry and create a good environment for the project.
Xinguang Silicon Industry's 1,000-ton polysilicon project has a total investment of 1.29 billion yuan. The product can be used in 8-12 inch electronic grade polysilicon, polysilicon for solar cells, and polysilicon for thyristor. The reporter was informed that within three months, Xinguang Silicon will begin mass production.
"Siam Dream" came true, and the dream did not stop. This year, Xinguang Silicon will strive to start construction of the second phase of 3,000 tons of polysilicon projects, and the downstream industrial chain project is about to start. It is expected to form an industrial cluster with sales revenue of 10 billion yuan.
China's first 1,000-ton polysilicon project was successfully commissioned in Sichuan
The drizzle brought a little bit of cold, but the people gathered in the Xinguang Silicon Industry Technology Company in Leshan High-tech Zone, the heat of the heart surged. Yesterday (1), a simple and solemn event was held here to celebrate the successful commissioning of the first 1,000-ton polysilicon project in China.
