Comparison and Analysis of Domestic Typical Slag Primary Treatment Process
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.
