以小方坯二维非稳态传热模型为工具,分析过热度和二冷配水制度对连铸坯内部质量的影响。在此基础上,提出一种基于中间罐温度连续测量和拉速前馈控制与铸坯表面温度反馈控制的二冷区动态控制模型
Taking the unsteady heat transfer model of billet as a tool, the influence of superheat and secondary cooling water distribution on the internal quality of continuous casting slab was analyzed. On this basis, a dynamic control model of secondary cooling zone based on continuous temperature measurement of intermediate tank, feedforward control of feed rate and surface temperature feedback control of slab
