Description
The superior coke is one of essential condition for blast furnace stable and
anterograde operation. Thus,the goal of the coking process is producing high-quality coke.
Under the current situation of the increasingly shortage of coking coal, how to get rid of the
dependence on high quality coking coal in the coke making production is a serious problem
that iron and steel must be confronted with. In this work, fundamental research was conducted
on the possibility of using brown coal as a raw material for coke making in order to achieve
the purpose of use of abundantbrown coal resources. Experimental result showed that the
Drum indexdecreased with an increase of brown coal addition.Results obtained testified that
the higher surface area of coke with brown coal addition caused a decrease in coke strength.
In order to attain suitable coke strength, the addition of brown coalshould be kept to be low
level, which the weight ratio of brown coal was supposed to be less than 6%.
