本文应用计算机数值模拟方法,研究了冷却制度、拉坯速度等工艺参数以及设备参数对矩形坯连铸过程的影响,为板坯连铸机改造成一机两流的矩形坯连铸机的设计提供了依据。改造设计时,尽可能地利用板坯连铸机的原有设备和结构,投资少、周期短、见效快,能够适应生产品种变化的要求。 In this paper, computer numerical simulation method was used to study the influence of the cooling system, the casting speed and other process parameters and equipment parameters on the continuous casting process of rectangular billet, and provided the design of the rectangular billet continuous caster The basis. In retrofitting the design, the original equipment and structure of slab caster should be used as much as possible, with less investment, short cycle and quick response, which can adapt to the requirements of variety of production variety.
