Abstract

The present invention is one kind of continuous magnesium producing apparatus with internally heating sealed vacuum electrically heating furnace. The continuous magnesium producing apparatus consists of a sealed vacuum electrically heating furnace and a solid magnesium cooling condensator connected to the sealed vacuum electrically heating furnace directly or through a liquid magnesium cooling condensator. The sealed vacuum electrically heating furnace is provided with refractory heat insulating layer, inside heating element, etc. The present invention has high heat efficiency, high heating speed, low power consumption, continuous production, low cost and other advantages.

Description

technical field [0001] The invention relates to machinery, in particular to a metal smelting equipment, especially to a continuous magnesium production equipment in a sealed vacuum electric furnace with internal heat method. Background technique [0002] At present, the traditional smelting equipment is mainly a reduction tank with an inner diameter of about 300mm and a length of about 2m. Coal or gas is used to heat the reduction tank and its contents, which is called "external heating method". In order to heat evenly, due to the limited volume of the tank, the thermal efficiency is low, and the reduction time is generally 8 to 12 hours. The traditional smelting equipment is intermittent production with low output, and the tank body is easily deformed under high temperature and vacuum conditions, with large loss, high cost, high labor intensity and environmental impact, so it needs to be improved. Contents of the invention [0003] The purpose of the present invention is...
