摘要
通过研究40kg试验焦炉单种煤焦炭、配合煤焦炭及工业焦炉焦炭的气孔结构及焦炭热性能,得出气孔率对焦炭热性能的影响。焦炭气孔率对焦炭热性能有较大影响,随着气孔率的增加,CRI增加,CSR降低;工业焦炉焦炭气孔率与焦炭热强度之间关系密切,气孔率每增加1%,CRI增加0.48%,CSR降低1.46%。用气孔率预测焦炭热性能,对指导焦炭生产、控制焦炭热性能具有指导意义。
Through the studies on the coke porous structure and coke hot property of the coke made with single coal and coke made with blended coal in 40kg test coke oven and coke made in industrial coke oven, the effect of coke porosity on coke hot properties is obtained. The coke porosity has greater influence on the coke hot property. CRI increases and CSR decreases with the porosity increase. The correlation between the porosity and hot strength of the coke from industrial coke oven is that if porosity is increased by 1%, CRI is increased by 0.48% and CSR is decreased by 1.46%. The coke hot property determination with porosity has a guiding significance for coke production and coke hot property control.
