Abstract

The present invention relates to a reduction furnace with tilting loading and discharging and its reduction method. The reduction furnace includes a furnace body, a reduction tank and a furnace body tilting mechanism. high temperature; the reduction tank is installed in the furnace body, both ends of which extend out of the furnace body, one end of the reduction tank is provided with a charging port, and the other end is provided with a slag discharge port; the furnace body tilting mechanism includes : the rotating shaft as the fulcrum of the rotary motion of the furnace body and the lifting mechanism driving the furnace body to rotate around the rotating shaft, the rotating shaft is arranged horizontally, and the reduction tank can at least rotate back and forth between a horizontal position and an inclined position. In the heating reduction process of the present invention, the reduction tank of the tilting charging and discharging type reduction furnace is in a horizontal position, and in the process of charging and slag removal, the reduction tank is in an inclined position, since the slag removal can be carried out automatically by utilizing the gravity of the earth, The production speed is improved, the amount of manual labor is reduced, and it is beneficial to realize the mechanization of production.

Description

[0001] This application is a divisional application, and its parent case is a Chinese patent application with the application number 200810239661.4, the application date is December 15, 2008, and the invention name is "Tilt-loading and discharge-type reduction furnace and its reduction method". technical field [0002] The invention relates to a metal vacuum smelting reduction furnace, in particular to a vacuum smelting reduction furnace for smelting metal magnesium or calcium. Background technique [0003] Some alkali metals and alkaline earth metals with high vapor pressure, such as chromium, chromium, magnesium, calcium, etc., can be prepared by metallothermic reduction of silicon, aluminum or their alloys under vacuum conditions. According to the different heating methods, the current silicothermal magnesium smelting can be divided into three types: one is the Pidgeon process (The Pidgeon Process), the other is the French semi-continuous magnesium smelting (The Magnetherm...
