板坯连铸实践表明,结晶器内钢水流动对铸坯质量和产品质量产生重大影响,控制结晶器内钢水流动已成为生产高质量产品和提高生产率的重要技术手段。综述了三类板坯连铸结晶器电磁控制流动(控流)技术的基本内容,对每类电磁控流技术,着重介绍了其配置和电磁力特征、冶金机理和冶金效果及其对最终产品质量的影响等。
The practice of slab continuous casting shows that the flow of molten steel in the mold has a significant influence on the slab quality and product quality. Controlling the flow of molten steel in the mold has become an important technical means for producing high quality products and improving productivity. The basic contents of electromagnetic control flow (control flow) technology for three types of slab continuous casting mold are summarized. For each type of electromagnetic flow control technology, its configuration and electromagnetic force characteristics, metallurgical mechanism and metallurgical effect are introduced emphatically, and their effects on the final product The impact of quality and so on.
