Abstract

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 rise 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.
