摘要
研究了7种单煤焦和1种配煤焦不同层次强度的影响因素。在焦炭显微特征中,影响因素较大的是焦炭平均壁厚B和光学各向异性指数H1。显微强度直接受焦炭孔壁的光学组织组成影响;结构强度受气孔率P和B影响较大;M40、M10主要取决于B和H1;CSR除受孔壁的厚度和孔壁的光学组成影响外,还与灰成分关系密切。对煤岩煤质指标参数影响较大的是炼焦煤的Rmax、S、∑I和G。
The factors that affect the different levels of coke strength of seven kinds of coke produced from seven single coals and one kind of coke from blended coal are studied.In the microstructure features of coke,the factors that have greater affect are the average wall thickness B of coke and optical heterosexual index H1.Microstrength is affected directly by the composition of optical organization of coke pore wall;the structural strength is influenced more greatly by porosity P and B,M40 and M10 depend mainly on B and H1,except that CSR is influenced by pore wall thickness and optical organization of pore wall,it has a close correlation with the composition of ash.The greater influences on petrology and coal quality index parameter are Rmax,S,∑I and G.
