Product detail:
Magnesia calcia tundishing coating materials
Refractory materials are used in industrial structures like furnaces, boilers, incinerators, and chemical reactors to protect them from intense heat. What they do is provide a type of insulation from the heat which these structures are exposed to; heat which can damage them and increase the need for costly repairs. But there are also problems which can arise during the creation process of refractory which can have damaging or even dangerous effects.
Company introduction:

Application:
Tundish coating of HN series is characterized by easy painting, no crack, erosion resistance, long service life and easy disassembly. Compared with using the insulation board, the tundish coating series can reduce nonmetallic inclusion in liquid steel, enhance cleanliness of liquid steel, improve steel property, reduce cost and increase performance.
Tundish coating HN-ZBTM4 is prepared specially for some types of steel with strict requirements on phosphorus content such as stainless steel, which compared with common tundish coating, can prevent phosphorus pollution of steel in tundish.
