Abstract
PURPOSE: To prepare high-quality metallurgical coke by synthetically adjusting cheap low-quality coal on the basis of a dry-base volatile matter content and max. Gieseler fluidity by adding a carbonaceous material with little volatile matter to prepare a raw material coal, which is molded and carbonized in a horizontal coke oven after compounded with fine coal.
CONSTITUTION: A low-quality coal which has not frequently been used because of a high dry-base volatile matter content is adjusted in the dry-base volatile matter content by compounding with a cheap carbonaceous material with exceedingly little volatile matter such as petraleum coke, fine coke or coal char to prepare a raw material coal for molding. It is pref. to adjust the dry-base volatile matter content to 18W82% and max. gieseler fluidity to 0.6W2.1. The raw materila coal shall contain not more than 27% carbonaceous material because of low caking capacity. A high-quality coke is obtd. by mixing the prepd. raw material coal with unmolded fine coal primarily consisting of high-quality caking coal followed by carbonization in a horizontal coke oven.
