Embodiment Construction

[0024] The embodiments of the present invention will be described in detail below in conjunction with the drawings, but the protection scope of the present invention is not limited by the embodiments.

[0025] As shown in the figure, a supporting structure for the upper tank of a double-row tank magnesium reduction furnace is composed of an upper tank brick 1 and a lower base checker brick 2. The upper pot holding brick 1 is saddle-shaped, and the middle of the saddle-shaped upper pot holding brick 1 is provided with a reinforcing connecting rib 3. The cross section of the reinforcing connecting rib 3 is any one of ellipse, rectangle, circle or polygon. The side surface of the upper pot brick 1 is provided with a concave diversion surface 4, and the concave diversion surface 4 is any one of an arcuate curved surface, an isolated intersection surface, an obtuse intersection surface or a right angle intersection surface. The lattice brick 2 of the lower base is a twin type connect...

Abstract

The invention relates to a double-row tank magnesium reduction furnace in the field of non-ferrous metal metallurgy, in particular to a bearing structure of an upper tank of the double-row tank magnesium reduction furnace, which consists of upper tank supporting bricks and lower pedestal lattice bricks, wherein, the upper tank supporting bricks take a shape of saddle, while the lower pedestal lattice bricks are twin type connected by a base. The invention solves the problems of poor strength of bearing bricking-up structure of the upper tank, easy damage, largely shielding heating to the lower part of a reduction tank, uneven heating of materials in the tanks, small flowing section of smoke in the furnace, uneven temperature in the furnace, and the like.

Description

technical field [0001] The invention relates to a double-row tank magnesium reduction furnace in the field of nonferrous metal smelting, in particular to a double-row tank magnesium reduction furnace upper tank support structure, which is used to improve the flue gas flow in the furnace and the heating uniformity of the tank body, and improve the material in the tank. Reduction output rate; increase the stability of the supporting masonry of the upper tank and improve the service life of the reduction furnace. Background technique [0002] The support structure of the upper tank is an important part of the double-row tank magnesium reduction furnace. Its main function is to support the magnesium reduction tank body in the reduction furnace to ensure that the tank body is evenly heated at high temperature, so that the materials in the tank can be kept at the temperature set by the process. The reduction reaction is successfully completed until the magnesium vapor overflows to...
