Abstract

The invention discloses a novel side-converter spray gun for smelting nonferrous metals, comprising a spray gun body with a sleeve structure and a spray gun head at the front end of the spray gun body; a central pipeline of the sleeve structure is provided with a connecting interface connected with a fuel conveyor; a sandwich ring channel of the sleeve structure is provided with a connecting interface connected with combustion-supporting gas; the spray gun head is provided with a fuel nozzle which is matched with the central pipeline and a combustion-supporting gas nozzle which is matched with the sandwich ring channel; and the combustion-supporting gas nozzle is provided with a through hole nozzle array.

Description

technical field [0001] The invention relates to a nonferrous metal smelting furnace spray gun, in particular to a nonferrous metal smelting side blowing furnace spray gun. Background technique [0002] With the advancement of smelting technology in the non-ferrous metal industry and the continuous improvement of ecological, environmental protection and energy-saving requirements, in recent years, the direct reduction smelting method of non-ferrous metals has replaced the original reduction smelting method and has become the mainstream of non-ferrous metal smelting methods. Due to the short process of the smelting method, good air tightness, good environmental protection, and low investment, the bath blowing smelting method gradually occupies the main position in the direct smelting method of non-ferrous metals. In the process of non-ferrous metal smelting, in order to stir the raw materials in the furnace, speed up the redox reaction speed, and improve the efficiency of smel...
