SG变质剂对白口铸铁性能及组织的影响

Effect of SG Modifier on Properties and Structure of White Cast Iron

研究了 SG变质剂对高铬钼白口铸铁组织和性能的影响，生产实践证明，经过 SG变质 的这种铸铁，使用寿命比高锰钢高 20％，每吨生产成本低 600元。

The effect of SG modifier on the structure and properties of high chrom ium－ molybdenum white iron was investigated.Productive practice verified that, c ompared with high manganese steel,this sort of white cast iron modified with t he SG modifier had 20％ longer working life and by 600 yuan cheaper cost/per t on.
