一、前言 近年来,用快速凝固的方法,将液态金属直接制成薄带的技术已日益发展,并受到越来越多国家的重视。薄带连铸的成功将省去锻造和热轧的常规工艺,意味着生产成本降低,生产过程简化,是钢铁生产上的一次技术革命,具有巨大的经济效益和社会效益。 目前,国内取向硅钢生产一直处在落后状态。虽从日本引进一套HiB取向硅钢生产线,但根本不能满足需要,加之取向硅钢生 I. Introduction In recent years, with rapid solidification method, the liquid metal directly into thin strip technology has been growing, and more and more countries attach importance. The success of strip casting will eliminate the conventional forging and hot rolling process, which means lower production costs, simplify the production process is a technological revolution in steel production, with great economic and social benefits. At present, the domestic oriented silicon steel production has been in a backward state. Although a HiB oriented silicon steel production line was introduced from Japan, it can not meet the needs at all. In addition,
