摘要:
A hot rolled silicon steel producing method comprises: silicon steel slab heating process, rough rolling process and finish rolling process. The heating process comprises a pre-heating stage, a heating stage and a soaking stage. The pre-heating stage satisfies the following formula (1). In the formula, VTp is a temperature increasing rate, in the pre-heating stage, whose unit is °C/min; t is a total heating time of the slab in the heating furnace, and t=180-240min; and Tc is an initial temperature when the slab is put into the furnace, whose unit is °C. By using the foregoing formula, the heating process and the rough rolling process are changed, an occurrence rate of edge defects during the production of the hot rolled silicon steel can be reduced, and the hot rolled silicon steel with good surface quality can be produced. V Tp > 220 min t × 100 ° C T C + 200 ° C × 25 ° C / min
摘要(中):
热轧硅钢的制造方法包括:硅钢板坯加热工序,粗轧工序和精轧工序。 加热过程包括预热阶段,加热阶段和均热阶段。 预热阶段满足下式(1)。 在配方中,VTp为预热阶段的升温速度,单位为℃/ min; t是加热炉中板坯的总加热时间,t = 180〜240min; Tc是板坯放入炉内时的初始温度,单位为℃。 通过使用上述公式,可以改变加热处理和粗轧工序,能够降低热轧硅钢的制造时的边缘缺陷的发生率,能够制造出具有良好的表面质量的热轧硅钢。 V Tp> 220 ¢min t×100 ¢¢¢¢C T C + 200 ¢° ¢C×25 ¢¢¢¢C / min
