Tundish magnesium spray coating

Sintered magnesia is used as the main raw material, and eight ultrafine powders, low temperature binders, plasticizers, water reducing agents and sintering agents are added. According to the composition of the ingredients, the electric furnace spray materials are constructed by mechanical spraying and manual application. The product has simple operation, high adhesion rate and low labor intensity. It can achieve fast baking, excellent corrosion resistance and no pollution to molten steel. After disintegration is easy.

Magnesium and magnesium-calcium materials are good for purifying molten steel, so they are widely used in continuous casting steel intermediate steel drums. However, when such coatings or sprays are used to cast low-phosphorus steel, the use of phosphate binders should be avoided. Secondly, because the paint adds a lot of water, it should be baked at high temperature to remove water, so as to avoid hydrogen in the first few barrels of molten steel.
