Load and equilibrium analysis of harmful elements in large blast furnace of Masteel
Based on tracking and calculation of input and output for harmful elements (K,Na,Zn,TiO2,Al2O3) in the large BF of Masteel,the main source,the ratio of the volume,change trend,concentration and the balance of input and output of harmful elements in raw materials of sinter,pellet and BF were studied.The research results indicated that the load of zinc and alkali metal elements in the large BF of Masteel were controlled within a range of the requirements,and the input and output balance was researched basically,but monthly average of harmful elements was fluctuated more.The blended ores and OG sludge in sinter raw matericals and the self-produced iron concentrate one in pellet raw materials were the main sources of the load of harmful elements in BF.The suggestion and measure to control the load of harmful elements in the large BF were proposed.
