焦炭抗拉强度的研究

Study on Tensile Strength of Coke

研究了单种煤焦炭抗拉强度与煤的 Rmax、Vdaf、G之间的关系 ,发现它们之间均呈现很好的曲线关系(中等变质程度的煤所得的焦炭抗拉强度高 ) ;且单种煤焦炭的抗拉强度与焦炭的结构强度 ,显微强度测定值之间存在有较好的相关关系 ;还研究了抗拉强度与气化量之间的关系 ,结果表明也存在良好的线性关系。

The relationship of coke tensile strength with R max ,V daf ,G of coal quality from single coal was studied.The results show that there exists curved line among them(coke tensile strength of medium rank coal has a higher value).The relationships of coke tensile strength to structural strength,microstrength and gasifying content for single coal were also studied.The results indicate that there exists clear relativity among them.
