Abstract

The invention relates to the technical field of pyrometallurgy, and discloses a charging cylinder for an Ausmelt furnace. According to the charging cylinder for the Ausmelt furnace, an opening of the charging cylinder is smaller than a material walking channel of the charging cylinder; a step transitional surface is used for transition between the opening of the charging cylinder and the material walking channel; and an air supply duct is arranged at the opening of the charging cylinder. By means of the charging cylinder for the Ausmelt furnace, raw materials can be effectively prevented from being bonded on the wall of the charging cylinder; the mass transfer rate of smelting is increased, the smoke rate and the temperature of the charging cylinder can be effectively lowered, and the charging cylinder can be prevented from being deformed; meanwhile, the frequency for replacing the charging cylinder is lowered, and the cleaning frequency by workers every day is lowered as well.

Description

technical field [0001] The invention relates to a charging cylinder convenient for an Osmelt furnace in the technical field of pyrometallurgy. Background technique [0002] At present, molten pool smelting is a smelting method in which the charge rapidly completes the main reaction between the gas-liquid-solid phase in the liquid molten pool (slag, matte). With the continuous strengthening of the smelting process by the advancement of modern molten pool smelting technology, the bed capacity of the molten pool melting furnace has been greatly improved. The molten pool enhanced smelting mainly achieves the purpose of smelting intensification by adding the charge into the strongly stirred molten pool, strengthening the smelting mass transfer process, and adding reactants (oxidants, reducing agents, vulcanizing agents, fuels, etc.). [0003] The usual feeding method for molten pool smelting is that the charge is fed into the molten pool through the top feeding port. Before rea...
