摘要
天津天管特殊钢有限公司采用电炉出钢钢水与感应炉熔炼合金钢水相兑,通过LF、VOD、模铸工艺生产HP13Cr超低碳不锈钢,分析和检验结果表明,吹氧后碳含量可达0.017%。VOD还原后,Mn、Cr、Si元素的平均收得率分别可达89.4%、98.4%、84.6%,钢锭锻造后的管坯冶金质量均满足技术标准要求。
HP13Cr ultra low carbon stainless steel is produced by EAF molten steel charged with IFmolten alloy steel through LF-VOD-Mould Casting process at Tianjin Tianguan Special Steel CompanyLimited. Analysis and test results show that carbon content after oxygen blowing can reach 0.017% andaverage yields of Mn, Cr and Si after VOD reduction, 89.4%, 98.4% and 84.6% respectively. The metallurgical quality of billet produced by ingot forging meets all requirements of technical standard.
