Abstract:The COREX smelting reduction iron-making technology has been used in the Baosteel Luojing project. It is a new technology in metallurgical industry presently characterized by the use of non-coke coal, shorter production routing with much off gas as production. This paper analyzes the features of COREX and coal dryers with COREX gas as fuel. Moreover, suggestions for coal preparation process are proposed which can supply the coal with less moisture. The author declaims that the coal dryer will show a new way of gas using in steel-making companies,and also it is more helpful for the coal transporting.
