The theory and practice of steel charging structural optimization in the electric steelmaking

摘要

In this article we expatiate our viewpoint about the harmful impurity element control problem, the charging structure problem and the influence of charging structure on producing index due to the diversification of charging structure in the electric steelmaking. In this article we put forward the harmful impurity element control model, the concept of the proportion of Iron and Steel and charging structure triangle. And through theoretical calculation and the statistical analysis we discuss the influence of charging structure on producing index, then figure that the utilizing proportion of energy will reduce as the increase of the proportion of Iron and Steel in the electric steelmaking.
