电工钢RH脱硫渣系研究
针对攀枝花钢钒有限公司难以稳定生产w(S)≤0.006%高级别电工钢的问题,通过开发RH脱硫剂、钢包渣改性及工艺参数控制,形成了RH脱硫系统工艺技术。经工业试验表明,采用该工艺技术后,钢水脱硫率最高达到42%,成品w(S)控制在0.005%以下,全氧、氮含量也得到了较好的控制,且脱硫剂没有引起钢水增碳,满足高级别电工钢的生产要求。 In light of the difficulty of production of high level electrical steel w(S)≤0.006 % steadily in Panzhihua steel & vanadium Co.,Ltd.the process technology of RH desulfurization system has been formed by developing the RH desulfurizer,modifying the ladle slag and controlling the process parameters.Industrial experiments show that the desulfurization rate of hot metal rises to 42 % and the w(S) of the finished products is controlled in below 0.005 % and total oxygen and nitrogen contents are a...
电工钢热连轧宽度自适应模型优化及应用
某厂对电工钢的轧制策略进行了优化,粗轧道次由“1+5”改为“1+3”。在优化后的生产过程中,每次变换钢种,烫辊材就会出现窄尺现象,而紧随其后的电工钢板则出现超宽现象。文中针对该问题,介绍了宽度设定模型和宽度自适应模型的原理,阐述了该问题出现的原因及解决方案,并通过对宽度自适应模型的应用研究及优化攻关,有效地解决了问题,大幅提升了实物质量,降低了宽度封锁率。 The rolling strategy of electrical steel was optimized in a factory,and the rough rolling pass was changed from “1+5”to“1+3”.Subsequently,the following problems were occurred in the production process:when the steel grade changed,the roasting roller steel before the electrical steel appeared the narrow width phenomenon,and then the electrical steel appeared the ultra-wide phenomenon.This paper introduced the principle of width setting model and width adaptive model,and expounded the causes and s...
