Description
technical field [0001] The invention relates to the charging process of a submerged arc furnace in the field of metallurgy, in particular to a driving device for a submerged arc furnace charging system and a charging system having the same. Background technique [0002] During the production process of semi-closed submerged arc furnace for smelting various alloys, a large amount of scorching furnace gas will be generated in the furnace, and the energy of scorching furnace gas will be fully utilized to create high-temperature chemical reaction conditions for various raw ores, while maintaining good gas permeability of the furnace charge , in order to accelerate the smooth progress of the chemical reaction in the furnace. When the air permeability in the submerged arc furnace is good, it can not only make full use of the heat energy of the high-temperature furnace gas to preheat the charge and reduce the volatilization loss of the main raw materials, but also help to reduce th...
