模具钢H13连铸关键技术优化与应用

Optimization and Application of Key Technology for Continuous Casting of Die Steel H13

为解决生产模具钢H13连铸过程中存在的问题,如脱引锭困难、铸坯切不断、切割端面不平、铸坯低倍质量差等。通过优化脱引锭位置和拉矫机热坯压力,开发铁粉喷吹切割,以及对电磁搅拌、轻压下工艺的研究,有效地解决了H13钢连铸生产中存在的难题,保证了连铸过程的稳定性。同时,提高了铸坯产品质量,取得了良好的经济效益。

In order to solve problems in the continuous casting process of die steel H13,such as difficulty in dummy bar removal,uncuttable slab,uneven cutting end face,poor low magnification quality slab and etc.,the dummy bar removal position and hot billet pressure of tension leveler are optimized,the iron powder injection cutting is developed, the electromagnetic stirring and soft reduction processes are studied and applied. Through these key technologies,problems existing in the continuous casting process of die steel H13 are effectively solved. This helps to ensure the stability of the continuous casting process,improves the quality of slab products,and also obtains good economic benefits.
