Slagging method for vertical retort magnesium smelting and vertical retort magnesium smelting device using same

Abstract

The invention relates to a slagging method for vertical retort magnesium smelting and a vertical retort magnesium smelting device. The method comprises the following steps: opening an upper cover, taking out accessories in a retort, and then closing the upper cover; opening a lower cover, laying a slagging device below a slag hole, adjusting an upward push cock of a rotary push rod of the slagging device, and opening the slag hole to remove slag charge; simultaneously driving a center tube with a blade by the cock to rotate or lift in a reduction retort to clean the slag charge; and adjustingthe slagging device after the slagging is finished, lowering down the rotary push rod, ensuring that the cock and the center tube are repositioned with the returning of the rotary push rod and finally the rotary push rod is separated from the cock, and then removing away the slagging device. The blade is installed on the center tube of the vertical retort magnesium smelting device, the cock is fixedly connected with the bottom of the center tube, the movable slagging device is arranged below the cock, the rotary push rod of the slagging device is matched and connected with the cock during slagging, and the rotary push rod is lowered down after slagging and automatically separated from the cock. The method has the advantages that the dust in a production field is reduced, the slag charge can be automatically cleaned up, and the slagging process can be controlled.

Description

technical field [0001] The invention relates to the field of nonferrous metal smelting, in particular to a method and device for smelting magnesium in a vertical pot. Background technique [0002] Vertical tank magnesium smelting is a relatively new magnesium smelting technology. The main feature of this technology is that the reduction tank is erected in the hearth of the reduction furnace, the upper part is fed, the lower part is slag discharged, and corresponding mechanical equipment is equipped to realize charging, magnesium discharge and Mechanization of operations such as slag discharge. Compared with the traditional horizontal tank magnesium smelting technology, it has many advantages, such as: increased single tank output, shortened production cycle, increased service life of reduction tank and improved working environment for workers, etc., can achieve energy saving, cost reduction, stable quality the goal of.

AI Technical Summary

Problems solved by technology

[0005] 1. When the slag is discharged, the gas in the reduction tank stirs violently, and the dust rushes out from the upper port of the reduction tank. The dust in the production site is serious, and the working environment for workers is harsh;

[0006] 2. The slag is easy to adhere to the inner wall of the reduction tank. The adhered slag is not only difficult to clean, but also reduces the effective volume of the reduction tank and reduces the amount of material in a single tank. ;

[0007] 3. The slag material falls by gravity, and the discharge speed of the slag material cannot be controlled
