分析了焦炭热性能测定反应炉刚玉质反应器下部破裂的原因,讨论了热性能炉上部密封状况对试验结果的影响,总结了不同制样方式对试验结果的影响。试验结果表明:刚玉质反应器下部与底盖之间的粘结剂应合理选择,热性能炉上部不密封会导致焦炭CSR偏低,机械制样相对于人工制样CSR偏高。 The reason for the rupture of the lower part of corundum reactor in the thermal performance of coke was analyzed. The influence of the sealing condition on the upper part of the thermal performance furnace to the test results was discussed. The influence of different sample preparation methods on the test results was also summarized. The test results show that the binder between the bottom of the corundum reactor and the bottom cover should be selected reasonably. The unsealed upper part of the furnace will lead to the low coke CSR, and the mechanical sample will be higher than the artificial sample CSR.
