Description

technical field

[0001] The invention relates to a slag processing system produced by blast furnace smelting and belongs to the technical field of blast furnace ironmaking. Background technique

[0002] The slag produced by blast furnace smelting can be widely used to make slag cement, heat insulation materials and other building materials after treatment. The blast furnace slag treatment processes adopted by most iron and steel enterprises today include drum dehydration method (Inba method and Tula method), slag pool filtration method (bottom filter method), dewatering tank type (Lhasa method), lifting dehydration type ( Stirring cage method and HK method), Jiaheng method, etc., these processes have their own characteristics, but more or less have their own shortcomings. For example, the Inba method uses a large drum to dehydrate water slag to achieve slag-water separation. This method has good treatment effect, high degree of mechanization and automation, and a good workin...
