提高连铸典拉率的实践

连铸钢水温度是连铸生产工艺的重要参数之一,直接影响连铸工艺过程以及铸坯表面、内在质量.华菱湘钢炼钢厂通过对4#铸机工艺过程和钢水温度变化规律的研究,制定出适合该厂4#铸机生产较理想的钢水过程温降控制制度,4#铸机连铸典拉率得到了明显提升.

Practices of Improving Pull Rate of Continuous Casting

The temperature of continuous casting steel water is one of the key parameters of the continuous casting process.The temperature has direct impact on whether the continuous casting can be conducted normally as well as the surface and interior quality of cast slabs.Hualing Xianggang Steel-making Factory has made researches on the process of 4~# cast machine and the temperature variation rule of steel water and made out relatively ideal temperature drop control system of steel water process suitable to the ac...
