Preparation method of non-oriented silicon steel hot-rolled strip steel and strip steel

The invention relates to a preparation method of non-oriented silicon steel hot-rolled strip steel and the strip steel, belongs to the technical field of hot rolling production, and aims to meet the rolling stability of high-silicon thin specification under the condition of ensuring low-temperature short-time heating by controlling each process parameter in a heating stage and avoid deterioration of magnetic performance of subsequent finished products caused by too high tapping temperature. Meanwhile, the rolling reduction of the rough rolling procedure is controlled, the process temperature drop is reduced, the strip threading speed is limited, the finish rolling stability is improved, hot rolled steel strips can be pressed to the target thickness, meanwhile, batch output is stable, and the problems that in the prior art, when high-silicon-content and thin-gauge silicon steel is produced, waste steel occurs, and the number of unqualified products is large are solved. 本申请涉及一种无取向硅钢热轧带钢的制备方法及带钢，属于热轧生产技术领域，通过在加热
