中间包修砌质量的工艺优化与应用

Process optimization and application for tundish repair quality

为了进一步提高中间包修砌质量,规范了中间包工作层干式料的布料操作,优化了包胎振动和烘烤工艺,设计修砌中间包专用水口泡沫塞,保证水口形状规则,使中间包修砌质量显著提高。中间包修砌合格率由92.5%提高到99.6%,降低了生产成本,达到连铸生产高效化,提高了中间包的使用安全性。

The distribution operation of dry mixes for tundish working layers was standardized,the vibration and baking processes of tundish were optimized,and special nozzle foam plugs for tundish repair were designed to ensure the regular shape of nozzles,significantly improving the tundish repair quality.The qualified rate of tundish repair increases from 92.5%to 99.6%,which reduces the production costs,achieves the high efficiency of continuous casting production,and improves the tundish safety in application.
