Abstract

The invention discloses a direct-current electric furnace smelting device for preparing metal chromium by aluminothermy. The device comprises a smelting furnace and a heat storage device; a heat circulating pipe is arranged on one side of the smelting furnace; the end part of the heat circulating pipe is embedded in the smelting furnace, and communicates with the smelting furnace; a base is arranged at the bottom of the smelting furnace, and is fixedly connected with the smelting furnace through a bolt; a support frame is mounted at the top end of the base, is embedded in the bottom of the smelting furnace, and is welded with the smelting furnace; foot pads are arranged at the bottom end of the base, and are fixedly connected with the base through bolts; the temperature storage device is arranged on one side of the smelting furnace; temperature storage pipes are arranged in the middle positions of the smelting furnace and the temperature storage device; and the temperature storage device comprises a temperature storer, a pressing nozzle and an induced draft fan. The device has the advantages of fast increment of pressure in the furnace, quick temperature rise, capability of realizing temperature storage, short waiting time in interval start, convenience to maintain and the like.

Description

technical field [0001] The invention relates to the field of smelting devices, in particular to a DC electric furnace smelting device used for producing metal chromium by the thermite method. Background technique [0002] Smelting refers to melting solid metal into liquid with a heating furnace and quenching and tempering. It is also one of the casting production processes. Metal materials and other auxiliary materials are put into the heating furnace to be melted and tempered, and the furnace charge undergoes certain physical and chemical changes in the furnace at high temperature (1300-1600K), and the pyrometallurgical process of producing crude metal or metal enrichment and slag . In addition to concentrate, calcined sand, sintered ore, etc., sometimes it is necessary to add a flux to make the charge easy to melt, and to add a reducing agent for a certain reaction. In addition, in order to provide the necessary temperature, it is often necessary to add fuel to burn and ...
