MgCaO-ramming
Compared with magnesia tundish coatings, dry ramming material has a short baking time and is easy to use, but the cost is higher. Many iron and steel enterprises use magnesia-calcium tundish coatings or dry ramming materials on continuous casting tundishes.

Magnesium calcium ramming material
As an amorphous refractory material containing CaO and MgO, magnesia-calcium ramming material is very popular in steel mills due to its excellent performance. long service life and good metallurgical effect. The magnesia-calcium ramming material uses magnesia and magnesia-calcium sand as the main raw materials, and uses solid resin or low-melting inorganic salt as a binder to configure 20%. Dry ramming construction is adopted, and the bonding agent is melted or solidified by heating the metal abrasive tool to form a fixed tundish working layer. Compared with magnesia tundish coatings, dry ramming material has a short baking time and is easy to use, but the cost is higher. Many iron and steel enterprises use magnesia-calcium tundish coatings or dry ramming materials on continuous casting tundishes.
