At the All-Union conference of blast-furnace operators in 1977 the basic requirements were formulated for the quality of metallurgical coke produced in Eastern USSR; these were size range 60-30 mm and mechanical strength according to the indices M25 88% and M10 7%. At the present time in the Kuzbas region, only coke from the Western Siberian metallurgical plant approaches the quality stated in terms of the basic physico-mechanical properties. Also, the metallurgical coke contains 40 to 65% of coke > 60 mm. The objections of blast furnace operators to the sizes > 60 mm in metallurgical coke is explained by the fact that this class is normally formed in the less hot zones of the coke mass and due to this the coke differs in having reduced mechanical strength and being more reactive. There is therefore considerable interest in investigations of the physico-mechanical and chemical properties of large coke size classes. It was found that the dry quenched coke from batteries nos. 1 to 4 and batteries nos. 5 to 7 differs from the wet quenched coke from the same batteries in having greater mechanical and structural strengths, lower porosity and reactivity. It is more stable to additional mechanical action than wet quenched coke from the same batteries. The extent of breakdown of the coke during the application of breakdown loads is less for the dry coke than for the wet coke. This is evidence for the possibility of further improving the quality of metallurgical coke at the Western Siberian I and SW by increasing the finishing off in the wide ovens, by making more use of dry coke quenching and also by the use of mechanical treatment.
