High Quality Magnesia Ramming Mass Refractory
Description of Magnesia Ramming Mass
Magnesia Ramming Mass is a monolithic refractory material mainly made of magnesium oxide, bauxite clinker, zirconia powder and coke clay. Magnesium tamping block is widely used as a lining for induction furnaces, electric arc furnaces and other high temperature applications due to its resistance to slag, abrasion, corrosion, high temperature and wear.
Features of Magnesia Ramming Mass
High refractoriness
Magnesium ramming mass has a high refractoriness, which means that it can withstand extremely high temperatures without melting or softening. This makes it suitable for applications where the lining material needs to withstand high temperatures.
Excellent thermal stability
Magnesia Ramming Mass have excellent thermal stability and maintain their physical and chemical properties even after prolonged exposure to high temperatures. This stability ensures the integrity and longevity of the refractory lining.
High purity
Magnesia Ramming Mass are typically manufactured from high purity magnesium, ensuring that the material contains very few impurities. This purity gives it excellent resistance to chemical attack, as well as to attack by molten metals and slag.
Good corrosion resistance
Magnesium ramming material has good corrosion resistance to molten metals, slag and other corrosive substances, protecting the furnace lining from chemical attack and erosion.
High bulk density
The high bulk density of magnesium ramming mass provides good mechanical strength and resistance to mechanical abrasion. ramming mass’s compact construction helps to maintain the integrity of the furnace lining under the weight and movement of molten metal and slag.
Easy to install
Magnesia ramming mass is usually supplied in semi-dry or dry form for easy installation. It can be tamped or rammed into the furnace lining using hand-held or pneumatic tools.
Fast setting and hardening
Once installed, Magnesia Ramming Mass sets and hardens quickly at high temperatures to form a strong, stable lining. This fast setting time results in a faster turnaround time for furnace repairs or relining.
Low residual expansion
Magnesia Ramming Mass has a low residual expansion, which means it expands or contracts very little during thermal cycling. This property helps minimize the risk of the refractory lining cracking or spalling due to thermal stress.
Good thermal shock resistance
Magnesia Ramming Mass have good thermal shock resistance and can withstand rapid temperature changes without significant damage. This is essential in applications where the furnace lining is subjected to frequent thermal cycling.
Application of Magnesia Ramming Mass
Induction Furnaces
Magnesium ramming mass is widely used as a lining for induction furnaces, which are used for melting and refining metals such as steel, iron, copper and aluminum. ramming mass forms a protective lining that can withstand the high temperatures and corrosive conditions of the molten metal and slag.
Electric Arc Furnaces
Magnesium ramming mass is used as a lining for electric arc furnaces in steelmaking and other metal melting processes. Magnesium compacts provide erosion-resistant and thermally stable linings that can withstand the high heat generated by electric arcs.
Ladles and Crucibles
Magnesia Ramming Mass is used as linings for ladles and crucibles, which are used to transfer and hold molten metal. ramming mass linings help protect ladles and crucibles from chemical attack and high temperature exposure.
Continuous Casting Ladle
In the continuous casting process, where the molten metal is solidified into continuous strands, magnesium ramming mass is used to line the ladles that transport the molten metal. ramming mass liners ensure the stability and integrity of the ladle during the continuous casting process.
Non-Ferrous Furnaces
Magnesium tamping compounds are used in non-ferrous metal furnaces, such as those for copper, aluminum and zinc production. ramming mass liners have excellent resistance to chemical attack and high temperatures, ensuring efficient and reliable metal production.
Ladle
Ladles for pouring steel into molds during the casting process can be lined with magnesium ramming mass. ramming mass liners protect the ladle from corrosion by the steel and maintain the temperature stability required for successful casting.
Glass Furnaces
Magnesium ramming mass can be used to line the working end of glass furnaces in certain glass manufacturing processes. ramming mass linings provide insulation and chemical resistance to molten glass, contributing to the efficiency and service life of the furnace.
