Problems solved by technology

[0002] At present, most domestic high-temperature equipment or containers are seriously sticky with slag, and mechanical slag removal devices are generally used, which will cause damage to the equipment and containers and shorten the service life. Manual methods are not only labor-intensive, but also It brings difficulty in slag dumping. To eliminate the above disadvantages, there is an urgent need for a material that can effectively prevent the above-mentioned high-temperature equipment or containers from being bonded by molten slag and liquid metal.

Abstract

The invention discloses a coating for high temperature devices or containers, and a preparation method thereof. The coating is prepared from, by weight, 40-50 parts of marbles, 40-50 parts of magnesia, 2-3 parts of zirconia, 2-6 parts of anhydrous phosphoric acid, 0.5-3 parts of calcium aluminate cement, 0.03-0.2 part of washing powder, 0.2-0.8 part of waste newspaper and 30-50 parts of water. Compared with coatings in the prior art, the product of the invention has resistance to high temperatures, oxidation and molten slag and liquid metal etching, has a moderate bonding strength, can effectively solve the problem of adhesion of molten slag and liquid metals of metallurgy and casting to furnace bodies and containers, and realizes the automatic slag removal of nondestructive devices.
