| Abstract;The extrusion force factors affecting the oven life are 1) the clearance between the coke cake and oven wall, 2) the mechanical properties of coke cake at extrusion (apparent Young's modulus, and Poisson's ratio), and 3) smoothness of the oven wall. The present investigation places the emphasis on the item 2), and effects of coal characteristics and operation conditions on the mechanical properties of coke is investigated. A test coke oven of the capacity of 250 kg is used for conducting dry distillation tests of various mixing ratios of coal, and the mechanical properties of the produced coke are evaluated by the apparent Young's modulus that is in a relation with the compressive load and cake compressibility, and the apparent Poisson's ratio is measured by the wall loads. The results obtained show that the effects of the coal characteristics on the extrusion force is mainly induced by the clearance, and that the effects of the mechanical properties of coke are minor. The effects of the bulk density and the oven temperature on the extrusion force are related to the clearance effect and the effect of the apparent Poisson's ratio that is one of the major mechanical properties of coke is not small. |
