Method of manufacturing green hot briquettes from fine coal for use in shaft furnaces

摘要

A method of manufacturing a briquetted coke from fine coal comprises carbonizing the coal at a temperature of from around 600° to 900. degree. C., mixing the carbonized coal with approximately 10 to 80% and preferably from 20 to 40% of fine coal well caking coal, and thereafter hot briquetting the mixture at temperatures of from around 300° to 500° C. A fuel for shaft furnaces preferably includes the use of the hot briquettes as the only solid fuel in the shaft furnace, and it is particularly applicable for blast furnaces.
