Abstract
PURPOSE: To prepare high quality metallurgical coke, by charging a carbonization chamber of a coke oven with briquette coal, covering the briquette with powdered coal, and conducting carbonization of the briquette, etc.
CONSTITUTION: A carbonization chamber 1 of a coke oven is charged with briqutte coal composed mainly of non- or slighyly caking coal and weakly caking coal and having a maximum fluidity measured by Giseler Plastometer of ≥5 D.D.P.M. (Dial Division per Minute) and a volatile content of 15-45%d (drybase %), until the level of the briquette layer reach ≥ 60% of the total height of the chamber 1. The top surface of the briquette layer is covered with powdered coal 3 having a maximum fluidity mesured by Giesler Plastometer of ≥ 20 D.D.P.M. with an average thickness of ≥ 20cm, and the surface of the powdered coal is levelled. When the spaces between coalbriquettes 4 are filled with powdered coal 5 resulted from the briquette coal, carbonization is carried out
