Smelting furnace

Abstract

The invention discloses a smelting furnace. The smelting furnace comprises a smelting bin, an air vent, a gas storage tank and a gas pipeline, wherein the air vent is arranged on one side of the smelting bin, a gas outlet of the gas storage tank is connected with the smelting bin through the gas pipeline, and a gas pressure regulating valve is arranged at the gas outlet of the gas storage tank, asteel crusher is arranged at the feed inlet of the smelting furnace, a conveying belt A is arranged at the bottom of the steel crusher, a molten metal thermometer is arranged on the inner side wall ofthe smelting bin, a precooling bin is arranged below the smelting bin, a fireproof brick layer is arranged between the smelting bin and the precooling bin, a movable door is arranged in the middle ofthe fireproof brick layer, a conveying belt B is arranged at the bottom of the precooling bin, a material conveying vehicle is arranged on the conveying belt B, the side wall of the precooling bin isprovided with a spray head, and the bottom of the precooling bin is provided with a drain pipe. According to the smelting furnace, the steel crusher is additionally arranged to crush waste metal, sothat the working efficiency of the smelting furnace is improved; and the precooling bin is additionally arranged to precool the molten metal, thereby reducing the heat insulation cost of the smeltingfurnace.

Description

technical field [0001] The invention relates to the field of metallurgical smelting, and more specifically relates to a smelting furnace. Background technique [0002] Smelting is a pyrometallurgical process in which scrap metal materials and other auxiliary materials are put into a heating furnace to be melted and tempered, and the material undergoes certain physical and chemical changes in the high-temperature furnace to produce crude metal or metal enrichment and slag. Existing smelting furnaces are equipped with high-temperature refractory bricks, but the refractory bricks are not only expensive but also reduce the volume of the smelting furnace to a certain extent, making scrap metal smelting incomplete and costly. Contents of the invention [0003] Purpose of the invention: the present invention aims at the shortcomings and deficiencies of the prior art, and provides a melting furnace. In the invention, a steel crusher is added to pulverize scrap metals before melti...
