Vertical reduction jar

Abstract

The invention provides a vertical reduction jar which comprises a main jar body and a discharge part, wherein the main jar body has a first diameter; the discharge part comprises a discharge cylinder body, a bowl mouth part and a sealing plate; the bowl mouth part is connected with the upper edge of the discharge cylinder body, and the sealing plate is arranged from a distance with the upper edge of the discharge cylinder body; the discharge cylinder body has a second diameter smaller than the first diameter; the transition between the main jar body and the discharge cylinder body is performed by the bowl mouth part; and the sealing plate is sealed with the lower edge of the main jar body. The welding part of the vertical reduction jar is deployed outside a hearth through the discharge part, and high temperature damage is reduced. When the inner part of the jar is blocked, only the original welding of the bottom is removed, repair and replacement can be completed. The vertical reduction jar has the advantages of good safety and convenience in maintenance, and prolongs the service life.

Description

technical field [0001] The invention relates to the field of smelting, in particular to a vertical reduction tank. Background technique [0002] In the prior art, the main method of metal magnesium production at home and abroad is still based on the horizontal reduction tank silithermal reduction method. The production process of this method is mainly: 1. The heat-resistant steel reduction tank is lying in the reduction furnace, Provide smelting temperature of 1200℃; 2. Mix the calcined dolomite with ferrosilicon fluorite, press the pellets, put them into the reduction tank, and vacuum them; 3. The pellets undergo a reduction reaction under vacuum and high temperature conditions to produce magnesium Steam and solid waste slag; 4. Magnesium steam is collected through crystallization barrels, while solid waste slag is sealed at one end of the furnace, and charging and slag discharge are carried out at the other end outside the furnace. In addition to the high temperature, it i...

Problems solved by technology

However, due to the welding seal between the reduction chamber and the conical constriction, the long-term high temperature in the furnace will damage the structure around the weld, and the large weight of the tank must be transmitted and supported through the weld, thus greatly affecting the reduction. The service life of the tank also has a lot of potential safety hazards
