THE INFLUENCE OF IRON--FLOW IN STEEL PRODUCTION PROCESS ON ITS IRON RESOURCE EFFICIENCY

Tiejun Dai, LU Zhong-wu

Open publisher page 3 citations

Abstract

The iron resource efficiency, for defining the degree of saving of natural iron resources in steel production process, was formulated. A standard iron-flow diagram of steel production process was given. The influences of iron-flow deviated in various ways from standard iron-flow diagram on iron resource efficiency were analyzed. The relationship between iron resource efficiency of steel production process and of its unit process has also been discussed. By using the data of a steel plant, the influences of iron-flow in steel production process on its iron resource efficiency were analyzed as an example.
