A deflector for a vertical reduction tank and its manufacturing method

Abstract

The invention provides a deflector for a vertical reduction tank, which includes a long cylinder and a cleaning device coaxially arranged with the cylinder, and the cylinder is provided with several holes that penetrate the cylinder wall and are parallel to the axis of the cylinder. The through hole, the cleaning device includes a central column and a scraper welded on the central column, a limit plate and a connecting part, the scraper runs through the through hole, and the blocked parts can be cleared and dredged by repeatedly pulling the cleaning device. The through hole greatly simplifies the cleaning work of the central tube of the reduction tank, and the cleaning work is carried out in the furnace, which can avoid the heavy work of removing and cleaning the deflector of the vertical reduction tank and the damage caused by the removal and cleaning of the deflector of the vertical reduction tank at high temperature Oxidative damage, improve the service life and work efficiency of vertical reduction tank deflector.

Description

technical field [0001] The invention relates to the field of smelting, in particular to a diversion device used on a vertical reduction tank for metal magnesium. Background technique [0002] In the existing technology, the main method of metal magnesium production at home and abroad is still based on the silicon thermal reduction method of the horizontal reduction tank (horizontal tank), while the vertical reduction tank (vertical tank) magnesium smelting is the rise after the horizontal reduction tank A new technology, the process principle and production steps are the same as those of the horizontal tank magnesium smelting, the main difference is that the reduction tank is vertically erected in the furnace, and the lower discharge port is opened, and the slag is fed from the upper part and the slag is discharged from the lower part by gravity. It facilitates the automatic and mechanized production of furnace charge filling and slag discharge, and reduces the labor intensi...

AI Technical Summary

Problems solved by technology

The openings are often blocked by reducing slag produced in the smelting process, which reduces the transmission channel of magnesium vapor, and the use of it has a great impact on the magnesium smelting process. Therefore, after a period of use, the diversion tube needs to be taken out of the reduction tank to clean the blockage. The reduction slag in the hole, taking out the guide tube from the high-temperature reduction tank is labor-intensive, and safety accidents such as burns are prone to occur, and the high-temperature guide tube is easily oxidized when exposed to air, shortening the service life
