小方坯冷却水的分析和优化

Analysis and optimization on cooling water of billet casting

九江钢铁公司炼钢厂小方坯因冷却水水质差和冷却工艺存在问题产生脱方、横裂和内部裂纹。通过设备改进和工艺优化,使方坯脱方、横裂、中间裂纹降到较低水平。

The quality problems of strands such as off- square, trasversal cracks and intemal cracks caused by the cooling water were analyzed at Jiujiang Iron and Steel Co. The optimization of the process was put forward and taken. After then, the quality of strands were improved remarkably.
