摘　　要：用粒经小于0.2mm的长焰煤、焦粉与焦油按一定比例混合,制得生产冶金焦的型煤粘结剂。配入1#煤浆粘结剂10%和3#煤浆粘结剂8%生产型煤,均可得到较高冷强度的型煤。该粘结剂配煤制得的型煤成型率为60%～75%,抗压强度大于100N/个,落下强度大于90%,满足了炼焦型煤生产、运输和装炉过程中的强度要求。Long flame coal with the grain size of less than 0.2mm, coke fine and coal tar were mixed together according to a certain proportion to prepare the binder for briquetted coal to produce metallurgical coke.10% of No.1 coal slurry binder and 8% of No.3 coal slurry binder were blended respectively to briquetted coal production, by which briquetted coal with higher cold strength can be obtained, the compressive strength was greater than 100N/off, the falling strength was greater than 90%, which can meet the strength requirement of briquetted coal for coke-making in the course of production, transport and charging.
