Title:
PROCESS FOR PRODUCING FERRO COKE FOR METALLURGY
Document Type and Number:
WIPO Patent Application WO/2011/108466
Kind Code:
A1
Abstract:
A process for producing ferro coke by carbonizing a molded object comprising a carbonaceous material and iron ore is provided. The process yields ferro coke which, in a blast furnace, shows enhanced reactivity of the coke contained therein with CO2. Thus, the temperature of a thermal reserve zone is reduced to enable a reduction in reducing-material ratio. The process for producing ferro coke for metallurgy comprises carbonizing a mixture comprising a carbonaceous material and iron ore to produce the ferro coke, and is characterized in that the ferro coke during the carbonization is heated to a maximum temperature in the range of 800-900ºC.
