Abstract:

Through analyzing on the coals for cokemaking in Xinjiang Tianyuan Coking Plant and by comparing with the coals outside Xinjiang，it can be concluded that coals produced in Xinjiang show the following properties，such as higher caking index，lower sulfur content，lower Gieseler fluidity index，lower Audibert-Arnu dilatation and higher alkaline oxide content，which result in a poor CSR of the coke produced.After coal blending optimization，i.e.high-alkaline-oxide-coal is minimized; the coke quality can be improved with CSR increased by 8%.
