METHOD FOR CONTROLLING NUTE COKE IN BLAST FURNACE

摘要

PURPOSE: A method of controlling the distribution of nut cokes in a furnace is provided to efficiently and cost-effectively perform a furnace process since nut cokes is distributed on the middle part of a furnace, so air permeability is improved. CONSTITUTION: A method of controlling the distribution of nut cokes in a furnace comprises next steps. After charging materials are discharged from a semicircle-shaped bunker(10), the charging materials are uniformly sprayed along the notch with a chute(5) toward the central part of a furnace from the wall of the furnace(1). The stay time of the charging materials in the semicircle-shaped bunker is shortest at an outlet since sudden downstream flow occurs along the right upper part of the outlet(11) of the bunker.
