文章以国内某公司硅钢厂连续退火机组1号辐射管加热段为研究对象,分析炉内传热机理,建立并开发了辐射管加热段的传热模型。采用生产实际数据对模型进行了验证,以总燃料消耗量最小为目标,得出该炉段长度方向上燃料的最佳分配机制。所得结论为该公司连续退火机组节能控制提供理论依据。 Taking the radiant tube heating section of No.1 continuous annealing unit in a silicon steel plant of a domestic company as the research object, the heat transfer mechanism in the furnace is analyzed, and the heat transfer model of the radiant tube heating section is established and developed. The model is verified by the actual production data. Aiming at the minimum total fuel consumption, the optimal fuel distribution mechanism in the length direction of the furnace section is obtained. The co... 

对RH法(真空循环脱气法)生产的冷轧硅钢的脱硫原理及影响因素进行了分析研究。研究表明:降低顶渣中FeO、MnO的含量,提高钢液温度,增加脱硫剂的加入量并延长其循环时间有利于提高脱硫效率。 The principles of desulfurization and its influence factors of cold rolling silicon steel during RH process have been studied in this paper.The result indicated that reducing contents of FeO and MnO,rising temperature of the liquid steel,increasing quantity of desulfurizer,lengthening cycle time of desulfurzer are benefit for desulfurization.

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...
