ore and coal used, the steel product mix, operation control technology, and material efficiency. • Energy is also consumed indirectly for the mining, preparation, and transportation of raw materials. In the blast furnace-basic oxygen furnace (BF-BOF) route, this accounts for about 9% of the total energy required toA novel controller for coal circulation and pulverized coal flow in a coal mill is proposed. The design is based on optimal control theory for bilinear systems with additional integral action.
