2号连铸机矩形坯断面改造与生产实践

Reconstruction and production practice of rectangular billet section of No.2 continuous casting machine

福建罗源闽光根据三钢(集团)发展规划需要,在2号连铸机150 mm×150 mm断面的基础之上,增加160 mm×230 mm矩形坯断面。通过设备改造和工艺参数优化,在满足铸坯质量的前提下,达到炉机匹配与快速切换断面的双目标,满足了生产要求。

According to the development plan of Sangang(group),Fujian Luoyuan Minguang Iron and Steel Co.,Ltd.added 160 mm×230 mm rectangular blank section on the basis of the 150 mm×150 mm section of No.2 continuous casting machine.Through the equipment transformation and the process parameter optimization,under the premise of satisfying the quality of the billet,the dual objectives of matching the furnace machine and rapidly switching the section were achieved,which satisfied the production requirements.
