compressive strength of coke
Jiaotan kangya qiangdu焦炭抗压强度(eompressive Strength。f coke) 焦炭在压力作用下断裂时，其单位面积上承受的力，即焦炭断裂时所能承受的最大压应力。它是反映焦炭力学性质的一项指标。试验是在恒定的应变速度下，对圆柱体焦样轴向加载，直至焦样断裂。其抗压强度叮一磊，Pa。式中尸为焦样断裂时所加的载荷，N;R为焦样截面半径，m。焦炭在轴向压力下的应变曲线大致分成四个区域。(见图)朋为初始区，焦炭在较低的轴向压力下，由于开气孔的闭合而发生较明显的应变，这是多孔材料的应变特征;贸为弹性区，应力- 训帕叮一__ 了:一。、一」/爪、_、一}川才z刀℃’} L一_匕一___~‘J___~___~~--一~~~砂 二、、.，.):‘上51}‘〕 位移，口们 室温下焦炭轴向压缩时的玉力一位移图应变近似于线性关系，c点为轴向压力达到的最大值;cD为脆性区，由于裂纹扩展，试样因受压而积蓄的能量被释放出来，但未达到破碎;DE为临界区，这时轴向力稍有增加，试样就产生很大的应变，并导致裂纹扩展。抗压强度试验是在材料试验机上进行的。一般焦炭试样制成直径约巧~、长约23~的圆柱体，型焦则用整块作试样。每种焦炭需取20个以上的试样作试验，应变速度为1.5X10一、”。室温下焦炭抗压强度大约为12一30MPa，在1 500℃高温下测量时，抗压强度值将增大20%左右。抗压强度的高低与气孔率大小有关。焦炭抗压强度比燕炭杭肚强度大一个数量级，它比焦炭在高炉内实际承受的压应力(约为0.ZMpa)大两个数量级，即焦炭的抗压强度远大于焦炭在高炉内承受的炉料压力，故压应力不是焦炭断裂的主要原因，对评定焦炭强度的意义不大。 (江中纸)
