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 the existing special paint for slag rakes is graphite, such as earthy 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 s...
