Title:
SHAFT FURNACE PROCESS FOR PRODUCING IRON COKE
Document Type and Number:
WIPO Patent Application WO/2018/094885
Kind Code:
A1
Abstract:
A shaft furnace process for producing iron coke. The iron coke produced by the shaft furnace process can partially replace an important raw material, coke, for a blast furnace production. The shaft furnace process for producing iron coke comprises the following main steps: after crushing iron ore and non-coking coal, mixing uniformly with a binder, briquetting, and drying; then adding briquettes into a carbonization chamber of a carbonization furnace by using a charging device; finishing reduction of iron and carbonization of the non-coking coal in the carbonization chamber by a preheating section and a carbonizing section, thereby forming the iron coke; and cooling the iron coke, discharging same, and charging same into an iron coke groove. The process has remarkable advantages that the process is advanced and reliable, can implement large-scale production of iron coke, provides good product quality, reduces the amount of used coke for blast furnace iron making, reduces the production costs of blast furnace iron making, improves the production efficiency of blast furnace iron making, reduces CO2 emission of blast furnace iron making, and the like.
