Abstract：Starting with research on the character of coals used for coking, Various factors affecting coke quality are analyzed, including ash and sulphur content, adhesivity and coking character, geological age of coal forming as well as active and inertia components. The counter measures are also put forward to improve coke quality, such as: optimizing coal preparation, strengthening stock management, stabilizing coal quality, adopting advanced technologies like dry coke quenching and constructing stable coal supply base.
