Material boat arranged in horizontally placed magnesium vacuum reduction tank

Abstract

The invention relates to the technical field of vacuum metallurgical equipment, in particular to a material boat arranged in a horizontally placed magnesium vacuum reduction tank. The material boat comprises a boat body, at least one baffle plate and a center flat pipe, wherein the radial profile of the boat body is symmetrical by using the center axis as the symmetry axis; a horizontal arc section, a tank cutting arc section, a vertical arc section and an upper wall arc section are sequentially arranged from top to bottom; the upper wall of the boat body is provided with a feeding opening andpenetrates through the left end and the right end of the boat body; the two ends of the boat body are sealed; at least one baffle plate is vertically arranged in the inner cavity of the boat body; the center flat pipe is horizontally arranged in the inner cavity of the boat body and penetrates through each baffle plate. The material boat has the advantages that the design is reasonable; the heattransfer efficiency is high; deformation cannot occur under the high temperature and vacuum conditions; the service life is long; the cost is low; the conditions are created for operations of magnesium melting mechanical loading and unloading, slag cleaning and the like. The material boat can be used for high-steam-pressure metal heat reduction process production of magnesium, lithium, strontium,calcium and the like.

Description

technical field [0001] The invention relates to the technical field of vacuum metallurgy equipment, in particular to a material boat placed in a horizontally placed magnesium vacuum reduction tank, which can be used to prepare magnesium, lithium, strontium, calcium and other high vapor pressure metals by thermal reduction. Background technique [0002] Magnesium, lithium, strontium, calcium and other high vapor pressure metals can be prepared under vacuum conditions by thermal reduction. The main methods of industrial magnesium smelting are electrolysis and thermal reduction. The thermal reduction magnesium smelting technology based on the silicothermal method (ie Pidgeon method) is relatively complete and is widely used by most domestic students. At present, most of the reduction tanks for magnesium smelting in my country have no heat source. Under the vacuum state, the heat from the outside is transmitted layer by layer from the outside to the inside in the form of radiat...

AI Technical Summary

Problems solved by technology

[0005]The problem existing in the prior art is that there is no heat source in the vast majority of magnesium smelting reduction tanks in our country, and the heat from the outside in the vacuum state is radiated gradually from the outside to the inside. The temperature of the central axis of the reduction tank is the lowest, and the pellet material is heated the slowest. This uneven temperature seriously restricts the improvement of the reduction rate; The implementation and operation of a series of mechanized measures such as material removal and slag removal prolong the time of the reduction process
