摘要
介绍了目前国内主流的钢渣一次处理工艺——坑式热焖法、罐式有压热焖法以及滚筒法——的工艺原理、技术特点以及系统组成,在此基础上对其进行了对比分析.一个钢厂选择何种钢渣处理工艺,需从钢渣处理规模、产品方案、建设条件、安全环保、投资等方面进行综合考虑.罐式有压热焖法或滚筒法装备自动化水平高,钢渣处理效果好,显著改善环境和工人劳动条件,安全性有所保障,有条件的企业应当优选这两种工艺.滚筒法流程短、占地少,但是设备相对庞大复杂,运行维护费用高,应从扩大钢渣处理范围、降低投资和运行成本等方面入手来加以改进;罐式有压热焖法工艺适应范围广、投资和控制运行成本低,相对来说市场占有率更高,应探索实现钢渣余热的规模化回收利用.
Abstract
The process principle,technical characteristics and system composition of current domestic typical steel slag primary treatment tech-nologies,such as pit-type hot stuffy process,pot-type pressurized hot stuffy process and BSSF(Baosteel's Slag Short Flow)process were intro-duced,thereafter a comparative analysis was made.Which steel slag treatment process to be selected by a steel plant should be comprehensive-ly considered in terms of steel slag treatment scale,product scheme,construction conditions,safety and environmental protection,investment,etc.Pot-type pressurized hot stuffy process and BSSF process should be preferred for their high equipment automation,good treatment effect,improved environment and working conditions as well as guaranteed safety.The BSSF process is short and has less land occupation,but the e-quipment is relatively large and complex,with high operating and maintenance costs.Improvements should be made from expanding the scope of steel slag treatment,reducing investment and operating costs,and other aspects.The Pot-type pressurized hot stuffy process has a wide range of applications,low investment and control operating costs,and relatively high market share.Therefore,it is necessary to explore the large-scale recovery and utilization of steel slag waste heat.
