The amount of dust removal ash generated during the steel smelting process of Anyang Base of Anyang Iron and Steel Group is about 10%of steel production.The dusts not only contain iron,but also some of them contain potassium,sodium,zinc and other elements,which cannot be directly used in the blast furnace smelting process.According to policy re-quirements of"solid waste not leaving the factory"in document No.381 of the Development and Reform Environmental Re-sources[2021]《Guiding Opinions on the Comprehensive Utilization of Bulk Solid Waste during the 14th Five-Year Plan》,it is clearly stated that the comprehensive utilization mode of bulk solid waste is innovated and the requirements of"solid waste does not leave the factory"in the iron and steel metallurgy industry.The Anyang base has strengthened the full quan-titative utilization of dust removal ash solid waste resources by building a dust removal ash resource disposal and utilization production line,and achieved good results.
