Special coating for slag harrow for removing slag of iron and steel

Abstract

The invention relates to a special-purpose coating material for steel slag removing harrows, which mainly 50-60% of soil form graphite, 20-30% of lamellar graphite, 10-20% of coke powder, 10-20% of calcium carbonate powder, and water 30-60% of the total amount of the constituents.

Description

technical field [0001] The invention relates to a coating, in particular to a special coating for slag rakes. The slag rake is a supporting device of a slag scraper or a slag scooper for removing slag in molten steel or ladle. Background technique [0002] When the slag rake of the steel (iron) water slag scraper or slag remover is working, it needs to be frequently dipped or brushed with paint. It has two main functions, one is to protect the slag rake by coating to avoid high temperature steel (iron) water corrosion; the other is to prevent iron slag from directly adhering to the metal surface of the slag rake and not easy to remove. [0003] The main component of existing coatings for slag rakes is graphite, such as amorphous graphite or flake graphite. Practice has proved that the current coating has the following major defects: the iron slag is too tightly and firmly bonded to the coating layer, and it is difficult to remove the iron slag on the surface of the slag ra...

AI Technical Summary

Problems solved by technology

Practice has proved that the current coatings have the following main defects: the iron slag and the coating layer are bonded too tightly and firmly, and it is difficult to remove the iron slag on the surface of the slag rake by the usual method, and manual scraping is required

It not only increases the amount of labor and reduces the production efficiency, but also has certain potential safety hazards

On the other hand, the work of carrying slag on the surface of the slag rake affects the normal operation of slag removal
