Relationship between M₁₀ coke qualitative parameter — wear resistance (from one side) and consumption of low-mesh coke of 10–25 mm fraction (coke nut) as well as ratio of skip coke replacement by coke nut (from other side) is investigated in order to decrease coke specific consumption. Optimal consumption parameters are obtained on the base of conducted analysis of production data of the furnaces during 2006–2011 for different coke quality.
