High temperature resistant ladle lining Magnesium Aluminum Spinel ramming mass
Magnesium aluminum spinel ramming mass is made of superior bauxite, high quality synthetic spinel, additive and binding agent, with the characters of strong resistance to slag erosion, excellent thermal shock resistance and high temperature strength, it is more and more used as steelmaking refractory material and it is an ideal ladle lining material.
Magnesium aluminum spinel ramming mass used in the ladle features:
a, High refractoriness to resist high temperature
b, Excellent thermal shock resistance performance to resist temperature shock
c, Convenient construction, it can be directly poured into lining and can be made into precast blocks for use.
d, Long service time and construction safety
