无取向硅钢由于硅含量高,导热系数低,铸坯组织和热轧组织具有与低碳钢不同的特点,特别是中高牌号硅钢,前部工序的组织对后面冷轧和连退工序生产中性能和表面质量产生影响。通过工艺控制可以获得对成品性能和表面质量有利的铸坯和热轧组织。
Non-oriented silicon steel due to high silicon content, low thermal conductivity, slab and hot-rolled organizations have different characteristics and low-carbon steel, especially in the high-grade silicon steel, the front of the organization on the back of the process of cold-rolling back and forth and back processes in the performance And surface quality have an impact. Through process control, it is possible to obtain a slab and a hot-rolled structure which are advantageous for the finished product properties and the surface quality.
