连铸结晶器保护渣性能改进

Improvement on properties of mold power for CC

本文阐述连铸保护渣性能改进的最新研究,涉及在颗粒保护渣中加膨胀剂、使用放热型开浇保护渣、改进保护渣添加技术、开发中碳钢高速连铸用保护渣、使用高粘度保护渣、以及保护渣成分对二次冷却水质的影响。

This paper describes the newest work of improving properties of mold powder for CC, which involves the addition of the expanding agent in spherical granules, the usage of exithermic starter powder, the improved adding technique of mold powder, the development of mold powder for middle carbon steel with high casting CC, the usage of high viscosity mold powders and the impact of mold powder chemisty on secondary cooling water.
