Design and Production Practice of Blast Furnace Based on High Proportion Pellet Smelting in Tangsteel
The furnace structure and cooling wall design for the physical,chemical and metallurgical properties of pellets from the beginning of design have been optimized for the iron-making system at Tangsteel coastal base in order to implement the development concept of"green and low carbon".Since the operation,by improving the coke quality and the low tem-perature reducing pulverization performance of flux-based pellets(RDI+6 3),stabilizing the charge structure,optimizing the operation system and other measures,under the current raw fuel conditions,the proportion of charging pellets into the furnace has stabilized above 40％,and the blast furnace has achieved a long-term stable forward running.The fuel ratio and coal ratio are controlled at about 520kg/t and 170kg/t respectively.
