Driving pressure during carbonization of single coal and blended coal were measured by means of oven with movable walls, and relations between driving pressure and properties of coal or coke were studied.
Maximum driving pressure of Japanese coal is lower than that of American coal imported, 0.19kg/cm2 of Shikamachi coal is highest in Japanese coal and generally below 0.13kg/cm2.Relation between driving pressure, coke button number, fuel ratio and shutter index of coke respectively were studied.When non-caking substance and coking coal is blended, maximum driving pressure decreases along straight line with in-crease of non-caking substance.When two kinds of coking coals are blended, relation between maximum driying pressure and blending proportion shows concave curve and there exist minimum point.
