Reduction furnace for smelting metal magnesium

Abstract

The invention relates to a reduction furnace, in particular to a reduction furnace for smelting metal magnesium. The reduction furnace for smelting metal magnesium comprises a furnace body, a steel frame supporting the furnace body, furnace walls, a reduction tank arranged on the furnace body, a vacuum system connected with the reduction tank and a combustion and fume systems arranged on two sides of the furnace body, and is characterized in that: at least two layers of burners capable of serving as fume outlet are arranged on furnace walls on the two sides of the reduction furnace; and the nozzles of the burners face the hearth of the reduction furnace. The reduction furnace has the advantages that: the unique combustion system is adaptable to various of flues; the temperature of the hearth is low; the loss is little; meanwhile, as fume waste heat recovery and storage technology is adopted, the air temperature for combustion is improved, the combustion effect is obviously improved and the temperature of exhaust fume of the reduction furnace is obviously reduced.

Description

technical field [0001] The invention relates to a reduction furnace, in particular to a reduction furnace for metal magnesium smelting. Background technique [0002] Traditional metal magnesium smelting reduction furnaces generally use solid fuel layered combustion, or gaseous fuels such as gas to heat the reduction tank. Insufficient combustion of solid fuel, discontinuous and unstable artificial fueling methods, and unreasonable flame structure lead to uneven temperature field in the reduction furnace, and the heat energy released by fuel combustion cannot be quickly and effectively transferred into the reduction tank; in recent years Although the developed gas-burning reduction furnace has partially solved the above problems, the uniformity of the temperature field in the reduction furnace has not been well resolved, especially when the reduction furnace is enlarged, the uniformity of the temperature in the furnace It is more prominent and seriously restricts the develop...
