废镁铬砖细粉在炼钢中包环保型干式振动料中的应用

Application of Waste Magnesite-chrome Brick Fine Powder to Environmental Protection Type Dry Vibrating Material for tundish

在相同条件下,在镁质干式振动料中加入不同比例的再生废镁铬砖料替代镁砂,对其物理性能进行检测对比。生产实践表明,该方法能够满足连铸中间包使用质量要求,性能指标接近对照试样,产品抗渣性能良好,有利于循环经济,对节约耐火材料矿物资源,保护环境具有积极意义。

Regenerative waste magnesite-chrome brick material in different ratios was added into magnesite dry vibrating material instead of magnesite under the same conditions and their physical properties were inspected and compared. Production practice showed this method could meet the quality requirement by tundish; the property indices were close to that of the compared samples and the slag resistance of the product was good. It favors cyclic economy and has active meanings to saving refractory resources and protecting the environment.
