Hot sale mass production Steel ladle used magnesia fire
bricks/magnesia carbon brick
Magnesia carbon brick is a high-melting-point alkaline oxide magnesia and a high melting point carbon material which is hard to be invaded by slag as a raw material, and various non-oxide additives are added. Magnesia carbon brick is a non-burning carbon composite refractory material which is combined with carbon binder.
Magnesia-carbon bricks are made of heavy-burned magnesia (or fused
magnesia) and carbon materials (mainly crystallized graphite), and
are pressed together with resin as a bonding material.
Magnesium carbon brick forms magnesium skeleton when used at high temperature. Because magnesium oxide and carbon do not produce mutual solubility relationship, the excellent fire resistance of the original component is retained, and the thermal conductivity of carbon is good, and the thermal expansion coefficient and elastic modulus are low , and it can effectively prevent high temperature spalling and slag penetration, so that structural spalling does not occur, greatly changing the fatal weakness of the metamorphic structure caused by the slag penetration of the magnesia refractory material, combined with the non-wetting property of carbon to the slag, and the corrosion resistance is very good.
This series of characteristics of magnesia carbon bricks makes it an ideal charge material for thermal shock resistance, erosion resistance and peeling resistance. Magnesia carbon bricks are widely used and can be used in key parts of thermal equipment such as steelmaking converters, electric arc furnaces, steel drums, and furnace refining furnaces.
We have added a vast variety of Magnesium Carbon Bricks, which is
manufactured using fused magnesia or burned magnesia in crystallite
size. Manufactured under the guidance of sedulous professionals,
our bricks are ensured for performing under higher pressure.
Also, these products have antioxidant material and are acclaimed
for possessing the following quality attributes:
1.Excellent corrosion resistance
2.High resistance to spalling
3.Free from dust particles
4.Optimum performance
