Technical Improvement on Improving Safety and Stability of Coal Injection and Pulverized Collection System of Blast Furnace
On the basis of analyzing the factors of safety and stability of coal injection and pulverized collection system of blast furnace,this paper puts forward the transformation scheme of replacing spiral conveyor with coal chute using"four-in-one"structure and replacing ash discharge valve with electric butterfly valve.After implementation,the pulverized coal leakage and equipment failure rate are reduced,and the safety and stability of coal injection and pulverized collection system is improved.
