Converter fettling material prepared from waste magnesian saggar and use method of converter fettling material

WANG ZHENFENG / ZHANG LIXIN

The invention provides a converter fettling material prepared from a waste magnesium sagger and a use method. The converter fettling material is prepared from a waste magnesium sagger material, magnesia aggregate, magnesium dihydrogen phosphate powder and a heating sintering aid. According to the invention, the waste magnesium sagger material is used as the converter fettling material, so that the purpose of full-value high-value utilization of the components of the waste magnesium sagger is achieved; the converter fettling material does not generate toxic and harmful gas, can avoid the defect that toxic and harmful gas is released in the combined sintering process of asphalt, and has the effects of high sintering speed and short fettling time compared with a traditional resin or asphalt converter fettling material (large and small surfaces of a converter); the fettling material has the advantages of being low in cost, capable of being suitable for the large face (and small face) portion of the converter and the trunnion portion, and good in fettling effect. The method has economic, environment-friendly and social positive significance in reducing waste sagger stockpiling land or facility occupation, reducing other environment-friendly negative effects and saving resources.

本发明提供了一种废弃镁质匣钵制取的转炉补炉料及使用方法，包括废弃镁质匣钵材料、镁砂骨料、磷酸二氢镁粉、发热烧结助剂。本发明将废弃镁质匣钵材料用作转炉补炉料，达到了废弃镁质匣钵成分全值高值利用的目的；本发明不产生有毒有害气体并可避免了沥青结合烧成过程中释放有毒有害气体的缺陷，比传统的树脂或沥青转炉补炉料（转炉大、小面）具有烧结快、补炉时间短的效果，本发明还具有补炉料成本低、能适用于转炉大面（和小面）部位、也能适用于耳轴部位、补炉效果好的优点。本发明对减少废弃匣钵堆存土地、或设施占用和减少其它环保负面作用，对节约资源均具经济、环保、社会等方面的积极意义。
