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...

通过对激光粒度分析仪测量硅钢级氧化镁(MgO)的分析条件进行优化,如分散介质、分散方式、样品预处理、仪器暗淡度等,探讨了硅钢级MgO粒度范围测量重现性较好的试验方法,满足硅钢生产过程控制对MgO粒度的要求。 The analysis condition of the laser particle size analyzer on grain oriented silicon-steel grade magnesium oxide is optimized,including the dispersion medium,dispersion methods,sample preparation,and instrument obscuration,etc.Therefore,particle size measurement with good reproducibility for silicon-steel magnesium oxide is discussed,which may meet the requirement of MgO particle size for silicon-steel process control.
