Method for resource utilization of copper slag through steelmaking process platform
The invention relates to process contents of two subjects of comprehensive resource utilization of copper slag and ferrous metallurgy process, in particular to a method for resource utilization of copper slag through a steelmaking process platform. After waste magnesia carbon bricks of a converter steel plant are subjected to process treatment, part of active materials are added and mixed with copper slag for pelletizing (the diameter of pellets is 5-50 mm), and the pellets are added into a slag tank along with steel slag flow in the slag tapping process after converter smelting is finished. According to the technology, the technological structure of the steel slag is optimized at the same time, and the economic benefits and the environmental protection benefits are huge.
本发明涉及铜渣综合资源化利用与钢铁冶金工艺两个学科的工艺内容，具体是一种通过炼钢工艺平台资源化利用铜渣的方法。本发明将转炉炼钢厂废弃的镁碳砖通过工艺处理后，添加部分活性材料，与铜渣混合造球（球团直径5～50mm），在转炉冶炼结束出渣过程中，随钢渣渣流加入到渣罐中，利用转炉钢渣的物理热和高碱度特点，还原回收铜渣中的重金属元素作为钢铁行业的原料资源化利用，本工艺同时优化了钢渣的工艺结构，经济效益和环保效益巨大。
