摘　　要：从配料比、堆积密度两个方面研究了由西沟肥煤与翼城无烟煤配合炼制所得焦炭的界面结合情况。研究表明 :配料中肥煤比例适当高一些 (40 %比30 % )为好。在配料比、粒度均相同的情况下 ,提高装料煤的堆积密度 (0.75→0.95→1.15),可使界面结合指数由63%提高到82 %。The interface of coke from Yicheng anthracite and Xigou fat coal blend has been examined under microscope. The effect of blending ratio and bulk density of charge is discussed. The result shows that the coke interface is related to the blend ratio. With the increasing of bulk density, the interface-bonding index increases from 63%to 82%.
