CN107812786A 一种用于生产无金属流动堆积缺陷的电工钢的热轧工艺 无效 - 驳回

一种用于生产无金属流动堆积缺陷的电工钢的热轧工艺
摘要：
本发明涉及一种用于生产无金属流动堆积缺陷的电工钢的热轧工艺，首先确定电工钢的化学组分，并将电工钢铸造呈板胚，电工钢的化学组分具体如下：C≤0.0025％，Si：0.38％～0.44％，Mn：0.24％～0.35％，P：0.06％～0.075％，S：＜0.0072％，Als：0.003％～0.004％，N：0.003％～0.0042％，其余为铁和不可避免的杂质元素。本发明具有提高钢带质量、大大方便钢带热轧工艺、通过改变热轧工艺、大大提高钢带的生产合格率等特点。
摘要（英）：

The invention relates to a hot rolling process for producing electrical steel free of a metal flow stacking defect. Firstly, chemical components of the electrical steel are determined, and the electrical steel is cast into a plate blank, wherein the chemical components of the electrical steel specifically comprise 0.0025% or less of C, 0.38%-0.44% of Si, 0.24-0.35% of Mn, 0.06%-0.075% of P, less than 0.0072% of S, 0.003%-0.004% of Als, 0.003%-0.0042% of N and the balance Fe and unavoidable impurity elements. The hot rolling process has the characteristics that the quality of steel strips is improved, the steel strip hot rolling process is greatly facilitated, and the production percent of pass of steel strips is greatly improved by changing the hot rolling process.
