我厂从80年下半年开始研制V—Ti下贝氏体球墨铸铁,在浙江大学,一机部上海材料研究所等单位进行了物理、化学和耐磨试验。通过鉴定会,证明性能良好,并开始投入生产。一、试制理由到目前为止,我省各电厂使用的磨球大多为锻钢球、马铁球、灰铸铁球,每吨煤的磨耗量为400克/T以上,要消耗很多金属材料,并对设备的磨损也很不利。我厂根据各电厂磨机 Since the second half of 1980, our factory has started the research and development of V-Ti bainite ductile iron, and conducted physical, chemical and abrasion-resistant tests at Zhejiang University and Shanghai Institute of Materials, a machine shop. Through the appraisal, to prove good performance, and began to put into production. First, trial reason So far, most of the power plant in our province to use ball grinding ball, horse iron ball, gray cast iron ball, per ton of coal consumption of 400 g / T or more, to consume a lot of metal materials, and Equipment wear is also unfavorable. I plant mill according to the power plant
