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.

According to reports, in order to understand the impact of Japan's Fukushima nuclear leak on the western Pacific Ocean and China's marine environment, from 16 June to 4 July 2011, the State Oceanic Administration conducted marine environmental radioactivity in the western Pacific Ocean east of Fukushima in Japan. monitor.
The monitoring results showed that 铯-137 and 锶-90 were detected in the seawater of the monitoring seawater. 94% of the monitoring station samples detected 铯-134.71% of the monitoring stations that could not be detected under normal conditions and the content of 铯-137 was higher than that in China. The background range of the sea area, the highest content of 铯-137 and 锶-90, respectively, is 300 times and 10 times the background area of ​​China's sea area. No iodine-131 was detected in seawater samples from monitoring sea areas.
The radioactivity detection results of the monitoring seabass (Bombyx mori) showed that the radioactive specific activity of strontium-90 is 29 times that of the radioactive background of coastal biological samples in China. In addition, silver-110m and plutonium-134, which were difficult to detect under normal conditions in our coastal biological samples, were also detected in the samples.
The State Oceanic Administration stated that in view of the significant impact of the Fukushima nuclear leakage on the western Pacific waters east of and east of Fukushima in Japan, it is recommended that relevant agencies strengthen the radioactivity detection of marine products from the sea area to ensure the public health and safety of our country.
On the 24th, it was learned from the State Oceanic Administration that the second batch of monitoring results of marine environment radioactivity carried out by the State Oceanic Administration in the western Pacific Ocean east of Fukushima in Japan showed that the western Pacific Ocean to the east and southeast of Fukushima in Japan had been subjected to Fukushima. Due to the significant impact of nuclear leakage, the radioactivity of ytterbium-90 in the marine biological samples of the monitoring sea area is 29 times that of the radioactive background of the coastal biological samples in China.
