30CrMnSi合结钢是用于制造较重要机械部件,技术性能要求严格的钢种。为了满足特级技术条件,如机械性能,高倍夹杂物,低倍缺陷无发纹等项技术要求,过去抚钢采用异炉渣洗法生产此钢种。但该工艺须有专用炼渣炉,为了炼渣需消耗电量和渣料,致使成本提高,而高倍和发纹缺陷的合格率也不高。为此对原工艺进行了改革。我们认为采用喷
30CrMnSi bonded steel is used to manufacture more important mechanical parts, technical performance requirements of steel. In order to meet the super-class technical conditions, such as mechanical properties, high magnification inclusions, low defects without hair lines and other technical requirements, the past Fushun different slag washing production of this steel. However, the process must have a dedicated slag furnace, in order to slag consumption and power consumption of slag, resulting in increased costs, and high-fold and hairline defect pass rate is not high. To this end the original process of reform. We think using spray
