Abstract:

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.
