针对目前二维动态配水模型的不足,中冶连铸自主研发了新一代的三维二冷配水系统。介绍了该系统的特点、原理和验证方法。并针对中厚板铸坯出现的质量问题,上线应用该系统,对设备、工艺参数等进行优化,制定合理的配水方案,改进设备、工艺参数,使得铸坯质量获得明显提升。 In response to the current lack of two-dimensional dynamic water distribution model, China Metallurgical Continuous Casting independently developed a new generation of three-dimensional cooling water distribution system. The system’s characteristics, principles and verification methods are introduced. In the light of the quality problems of the slab, the system is applied on-line to optimize the equipment and process parameters, formulate a reasonable water distribution scheme, improve the equipment and process parameters, and improve the quality of the slab.
