一筛分筛子是百花岭选矿厂磨浮车间出矿端的重要备件之一,由钢筋、角铁焊制而成,实际应用表明,该制品制作费用高(4400元/件)、寿命短(仅半个月),按两组一筛分筛子计,年需一筛分筛子48件,费用为211200元,若用铬微合金化高锰钢生产一筛分筛子,以生产成本6000元、使用寿命6个月计,年维修费用仅24000元,具有较好的经济效益。1材质选择高锰钢作为一种耐磨材料,被广泛用在水泥、电力、矿山、冶金、建材等行业。由于高锰钢是一种高韧性奥氏体钢,在非强冲击使用条件下韧性过大而耐
A screening sieve is one of the important spare parts for the ore-dressing end of the grinding plant in Baihualing Concentrator. It is made of steel bar and angle iron. The practical application shows that the product has high production cost (4400 yuan / piece) and short life (only Half a month), according to two groups of one sieve sieve, the annual sieve to be a sieve 48, the cost of 211200 yuan, if the use of chromium microalloyed high manganese steel to produce a sieve, the production cost of 6,000 yuan, the use of Life expectancy of 6 months, annual maintenance costs only 24,000 yuan, with good economic returns. 1 Material Selection High manganese steel as a wear-resistant materials, are widely used in cement, electricity, mining, metallurgy, building materials and other industries. As high manganese steel is a high toughness austenitic steel, under the conditions of non-impact toughness is too large and resistant
