Abstract:
Based on the experiment developed in Shanghai No.5 Steel(Group) Co.,Ltd, EAF Steelmaking Plant, the Process of HBI, transportation and stockpile of HBI, nd the use of HBI in 100 t DC EAF has been discussed. By analyzing experiment results of 97 heats, the influence of charging HBI into the EAF on economy and technology index, such as electricity consumption, productivity tap-to-tap time, and the steel making process, such as desulfurization, dephosphorization, residual elements removal, nitrogen removal etc. has been studied, and the reasonable methods of charging HBI in EAF has been established, and optimized charging order of the HBI has been obtained, and the experience of transportation, Store and using of the HBI has been accumulated.
