Magnesium oxide stirring device

Abstract

A magnesium oxide stirring device is composed of a U-shaped bottom groove (1), a fixing shaft (2), a left shaft sleeve (3), a right shaft sleeve (4), a handle (5), a scraping plate (6), a stirring mesh (7), an air cylinder (8) and a limiting block (9). A plurality of handles (5) are welded on the left side of the left shaft sleeve (3), and a scraping plate (6) is connected on the right side of the left shaft sleeve (3). A piston of the air cylinder (8) moves to drive the stirring mesh (7) to stir a magnesium carbonate and magnesium hydroxide mixed solution in the U-shaped bottom groove (1), agglomeration and deposition of the mixed solution are avoided, meanwhile, deposition blocks attached to the brush roller are scraped off through the scraper (6), the coating quality of the brush roller is effectively improved, the working time of the brush roller is prolonged, the production efficiency is improved, and the production cost is reduced. The waste of the magnesium oxide solution and the silicon steel coil is avoided.

Description

technical field [0001] The invention relates to the field of continuous automatic production of silicon steel, in particular to a magnesium oxide stirring device. Background technique [0002] Before the silicon steel coil is annealed at high temperature in the bell furnace, a layer of magnesium oxide powder must be coated on the upper and lower surfaces of the steel strip with a brush roller to prevent the steel strip from sticking during the high temperature annealing stage, and at the same time remove the Impurities such as nitrogen and sulfur, and more importantly, magnesium oxide will react with silicon dioxide on the surface of silicon steel to form a magnesium silicate insulating bottom layer, so the coating quality of magnesium oxide on the surface of silicon steel plays a vital role in the quality of silicon steel products . Due to the poor fluidity of the mixed solution of magnesium carbonate and magnesium hydroxide configured with magnesium oxide, it is easy to c...

AI Technical Summary

Problems solved by technology

Due to the poor fluidity of the mixed solution of magnesium carbonate and magnesium hydroxide configured with magnesium oxide, it is easy to cause agglomeration and deposition. When the fluidity of the mixed solution of magnesium carbonate and magnesium hydroxide in the tray is not high, it is easy to accumulate scaling, resulting in Coating quality deteriorates, and double lines of different widths and quantities often appear on the surface of the board in batches, directly causing product quality defects; in serious cases, it is necessary to stop the machine to replace the brush roller, clean the blockage of the circulation pipe, and deal with the scaling of the pallet

This not only greatly increases the labor intensity of workers, but also interferes with continuous production on site, reduces production efficiency, and causes waste of magnesium oxide solution and silicon steel coils
