The authors compare differential crushing with standard crushing methods and suggest an optimum size consist for maximum charge density and improved Micum values. Preheating charges to 100-150 C has been found to increase coke strength by 4-5% (M40) and reduce abrasion by 1.5%, as well as improving considerably the oven throughput due to the increased bulk density of the charge and the shortened coking period. Carbonization research has shown that with increasing flue temperature and longer coking time, the product is smaller and more uniform in size. Raising the rate of heating tends to reduce the +80 mm material and smooth out size differences. Oven width can be discounted as a critical factor. Dry, rather than wet, quenching is preferable, giving uniformity of size and strength.
