The 2010 emission reduction target is: Under the circumstance that the emission of sulfur dioxide is completed one year ahead of schedule, it will strive to cut 400,000 tons more than in 2009; COD emission reduction will be based on the completion of the “Eleventh Five-Year Plan†target. Strive to cut more than 200,000 tons. Ensure that the daily treatment capacity of newly added urban sewage is 10 million cubic meters, and the installed desulfurization capacity of new coal-fired power plants is 50 million kilowatts.
According to preliminary calculations, the national chemical oxygen demand and sulfur dioxide emissions continue to maintain a double downward trend in 2009, and sulfur dioxide “Eleventh Five-Year†emission reduction targets are achieved one year ahead of schedule. The proportion of Grade I-III water quality at the national control section was 48.2%, which was a year-on-year increase of 0.5%. The annual average concentration of permanganate in the national control surface water surface of the country was 5.1 mg/l, which was 10.5% lower than that in 2008 and 29.2% lower than that in 2005. According to the annual average, the ratio of air quality in 113 key environmental protection cities meeting or exceeding the national secondary standards was 65.5%, an increase of 8 percentage points year-on-year.
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.
