Fluid director for upright reducing pot and manufacturing method thereof

Abstract

The invention discloses a fluid director for an upright reducing pot and a manufacturing method thereof. The fluid director for the upright reducing pot comprises a longitudinal barrel body and a cleaning device coaxial with the barrel body, a plurality of through holes which run through the barrel wall and are parallel to the axial line of the barrel body are opened in the barrel body, the cleaning device comprises a central post, and a scraper blade, a limit plate and a connecting part welded on the central post, the scraper blade runs through the through holes, the blocked through holes can be cleaned through repeatedly pulling the cleaning device, the cleaning work for a central pipe of the reducing pot is greatly simplified, and moreover, the cleaning work is performed in the furnace, the heavy work due to taking out the fluid director of the upright reducing pot to clean and the oxidization damage due to taking out the high-temperature upright reducing pot fluid director to clean can be avoided, and the service life and working efficiency of the fluid director for the upright reducing pot are improved.

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
