Abstract:  Domestic coking coal and other main high-quality coking coal are in short supply in China， and the use of high sulfur coal resources is restrained due to high sulfur content. When large proportion of low-sulfur anthracite is mixed，high-sulfur fat coals should be appropriately added according to the behaviors of the coal kind. For environment-friendly heat recovery stamp-charge battery，qualified coke product with CSR≥60% can be produced by accelerating heat-up rate at early coking stage， maintaining constant temperature in coking chamber at middle stage，and appropriately prolonging the soaking time. This solution can dramatically reduce the coal blending cost.
