Blast-furnace charging system

The blast furnace in the blast-furnace shop at the West Slovakian Metallurgical Combine is charged by means qf a complex sYstem that usually includes the.fbIlowing: an ore.vard tvith a hopper gantry: a sYstein to collect, weigh, and transport the charge materials to the top of the furnace; the charging apparatus of the furnace; a system that controls the charging operation. The use of continuous-acting mechanisms facilitates charging of the ore-bearing materials in the charge while minimizing the content of the -5-min fraction of these components and the number of coke particles smaller than 25 nun. The productivity of the furnace could be increased further; which would allow the addition of an efficient aspiration system and make it easier to fully automate the furnace.
