Abstract
Gieseler fluidity characterization is an important method to evaluate the fluidity of coal which highly influences the cohesive properties of coke formation. A concept of fluidity-temperature area SlgF instead of maximum fluidity lgMF was put forward to be used as the index of Gieseler fluidity characterization. Thirty-five coal samples were tested by Gieseler characterization and the sensitivity for identifying coal cohesiveness by SlgF and lgMF were compared. It was found that SlgF has a more sensitive resolution of coal fluidity than lgMF and it could give a correct result for judging coal cohesiveness in accordance with the comprehensive cohesiveness in most cases, especially for coals having almost same lgMF values.
