摘要
新日铁针对取向硅钢热轧板存在的边裂问题,采取了电磁搅拌、连铸板坯直送边部加热、实施板坯边部压下、电磁感应加热、控冷控轧、控制热轧精轧开始温度和终了温度、最终道次压下率及加热温度、控制组织、减少边部与中间的温度差异、消除狗骨等一系列措施,取得了明显效果。
Aiming at hot-rolling edge cracking existed in grain-oriented silicon steel, some measures are adopted in Nippon Steel, such as: electro-magnetic stirring; casting slab direct-transportation edge heating, slab edge rolling, electro-magnetic induction heating, controlled cooling and rolling, controlling finishing rolling temperature, adjusting reduction in final pass and heat temperature,decreasing temperature discrepancy between edge and center, eliminating dog skeleton. After that, good results are obtained.
