一、前言在球磨机中耐磨件消耗量最大的是磨球。我国每年消耗磨球的数量很大,尤其在火力发电厂中,因种种原因,从而造成磨耗很高,浪费了国家大量的材料和资金。我厂在电力部、省电力工业局的大力支持下,在抓好年产3000t磨球生产线的筹建工作中,对如何改善碳化物形态(球状化等)来达到提高白口铸铁韧性的良好作用,有利十提高磨球的抗磨问题等,进行了理论分析和生产试验,因而证实了经过一定量的稀上等合金进行变质处理的高铬铸铁磨球其冲击值能稳定在9～15.5 J/cm~2,有很好的安全性、经济性。制出的煤粉,在炉内燃烧不易结焦,是发电厂球磨机
First, the preface In the ball mill wear parts consumption is the largest ball. China consumes a large number of balls every year, especially in thermal power plants, for various reasons, resulting in high wear and tear, wasting a lot of national materials and funds. I plant in the Ministry of Electricity, Power Industry Bureau with the strong support of the annual output of 3000t grinding ball production line construction, how to improve the carbide morphology (spherical, etc.) to improve the toughness of white cast iron good effect , Ten to improve the anti-wear ball grinding problems, conducted a theoretical analysis and production tests, thus confirming a certain amount of high alloy corrosion modification of high-chromium cast iron ball impact value can be stabilized at 9 ~ 15.5 J / cm ~ 2, there is a good safety, economy. Produced by the coal, not easy to burn in the furnace coking, power plant ball mill
