板坯连铸恒拉速浇铸提高铸坯质量

Constant Speed Casting Improves Slab Quality

以连铸为中心组织生产,提高钢水成分命中率,减少钢水中S、P和夹杂物质量分数,提高中包温度命中率,选择合适的目标拉速,保证生产节奏稳定,优化保护渣性能,提高连铸操作水平,加强连铸设备保障能力等可以提高连铸恒速率。恒拉速操作可以提高连铸坯表面质量和内部质量。

Constant speed casting was put on the base, such as the center position of continuous casting, increasing the shoot straight of composition, reducing the content of S or P and inclusion in the steel, increasing the shoot straight of temperature in tundish, choosing a suitable casting speed, optimizing the performance of powder, improving the operating level and enhan- cing the capability of equipment. Constant speed casting can improve the surface and interior quality of the slab.
