硅钢生产技术的必威体育精装版进展及开发建议 周国平 孙 力 梁振威 于世川 (河北钢铁集团唐钢冷轧薄板厂，唐山 063016) 摘 要 本文在介绍硅钢技术的必威体育精装版进展及其质量控制难点的基础上，通过对硅钢必威体育精装版市场需求和供应的分析，结 合唐钢实际，提出了唐钢开发硅钢的几点建议，认为唐钢现阶段重点应结合现有装备和工艺特点生产中、低牌号无 取向硅钢，在其 1810 短流程热轧线上，首先采取“炼钢(超低碳)—热轧—酸轧—半工艺硅钢”的工艺路线批量生 产中、低牌号半工艺冷轧无取向硅钢，并尽快新建配套的退火和涂层生产线，迅速形成中、低牌号无取向硅钢退火 涂层产品的批量生产能力。远期可考虑生产取向硅钢。 关键词 硅钢 市场 唐钢 Latest Development of Silicon Steel Production Technologies and Developing Advice Zhou Guoping Sun Li Liang Zhenwei Yu Shichuan (Cold Rolling Strip Plant, Tangsteel, Heibei Iron and Steel Group, Tangshan, 063016) Abstract In the present work, on the base of describing the latest progress and quality control difficulties of electrical steel technology, considering Tangsteel actual situation, several suggestions on developing electrical steel for Tangsteel are brought forward by the latest market demand and supply analysis. It was proposed that at the current stage, Tangsteel should focus on developing middle and low-grade non-oriented electrical steel by using of existing equipment and production processes; firstly, should produce semi-process middle and low-grade cold rolled non-oriented electrical steel in a large quantity by taking the process line of “steel making (ultra low carbon-hot rolling-pickling and cold rolling-semi-process electrical steel” in the short flow hot rolling line with the work roll barrel length of 1810mm, and then build the new annealing and coating production lines as soon as possible, rapidly forming the mass production capacity of the annealed coating middle and low grade non-oriented electrical steel products. In the long run, the oriented electrical steel prod
