盖包法球化处理工艺优化

The Optimization of Tundish-Cover Spheroidizing Process

针对球墨铸铁球化处理工艺,总结了盖包法球化处理生产中常见的装卸包盖操作困难、球化处理时铁液飞溅、出铁量难定量、包盖密封性不好等问题,并对这些常见问题提出了解决措施。实践证明,采用优化设计的球化处理装置和工艺可使盖包法球化处理工艺生产稳定性更好,操作更方便,适应性更强。

The common problems in the tundish-cover spheroidizing process for the ductile iron, such as the difficulties of loading and unloading the ladle cover, the splash of molten iron in spheroidization, the difficulties of fixing the iron amount, and the bad tightness of the ladle cover were summarized, and the solutions were put forward. The practice results show that adopting optimization design of spheroidization device and technology in the tundish-cover spheroidizing process, production stability is better, operation is more convenient, and its adaotabilitv is better.
