Anode furnace oxido-reduction mouth brick hot-state replacement method and novel anode furnace

Abstract

The invention provides an anode furnace oxido-reduction mouth brick hot-state replacement method. The method comprises the steps of manufacturing a rectangular steel plate mold, manufacturing conical refractory bricks and the like. A novel anode furnace comprises a furnace shell, a reaction furnace, square refractory bricks, a furnace shell arc-shaped movable steel plate, an oxido-reduction tube, the conical refractory bricks and the steel plate mold. The anode furnace oxido-reduction mouth brick hot-state replacement method aims at solving the problem that production is influenced by replacement of the refractory bricks at an oxido-reduction mouth of the anode furnace in the industry, shortening the time of influence of replacement of the bricks at the oxido-reduction mouth on production as much as possible, guaranteeing that the effective production time is long and effectively controlling the production operation cost; hot-state replacement of the bricks at the oxido-reduction mouth of the anode furnace is achieved, the replacement time is shortened, and the labor intensity of workers replacing the bricks at the oxido-reduction mouth is relieved.

Description

technical field

[0001] The invention belongs to the technical field of nonferrous metallurgical equipment, and in particular relates to a novel anode furnace. Background technique

[0002] The refractory brick area of ​​the redox port of the anode furnace is the area with the largest fluctuations in the working conditions of the anode furnace body. This area has been spraying compressed air into the furnace for a long time, or spraying solid reducing agent or reducing gas for reduction operations, making this area refractory The bricks are in the alternation of cold and heat for a long time, and the magnesia refractory bricks are easily corroded or consumed. Generally, the service life of magnesia refractory bricks in other areas of the anode furnace is more than 2 years or even longer. However, the service life of redox magnesia refractory bricks is generally about 3 months, that is, it is eroded to a thickness of less than 300mm, which is an unsafe thickness. . For this ...
