What are magnesia carbon bricks. magnesia carbon bricks are made from high melting point basic magnesium oxide, high melting carbon which is difficult to be embellish by the slag and a variety of non oxide additives, making non carbonaceous composite magnesia carbon refractory bricks by combining with carbonaceous binder.
Various refractory grogs are currently being reclaimed for use in the production of mainly monolithic refractory materials. these include used refractory bricks and monolithics based on chamotte, andalusite, bauxite, high alumina, silicon carbide, magnesia, magnesiachrome, magnesiaspinel, magnesiacarbon, dolomite and graphitecarbon.

Magnesia carbon brick . product description magnesia carbon brick for eaf are made through a process of highpressure molding and lowtemperature treatment, using fused magnesia, highpurity magnesia sand and graphite.
May 03, 2017 i am willng to introduce more information for you. magnesiacarbon bricks are resin bonded bricks containing highpurity fused and or sintered magnesia and flake graphite as their main ingredients. composition changxing refractory is able to manu
The different types of degradation that the material suffers can be from thermochemical or thermomechanical origin. in this work, the youngs modulus, the fracture resistance and the thermal expansion coefficient of three commercial magnesiacarbon bricks a, b, and c were measured to evaluate their resistance to thermomechanical degradation.
Mgoc brick is a composite material based on mgo and c and bonded with high carbon containing pitch and resin, with some metallic powder as antioxidants to protect the carbon. mgoc bricks are made by high pressure. these bricks show excellent resistance to thermal shock and slag corrosion at elevated temperatures.
Typical waste refractories that can be recycled include firebrick, midalumina brick, bauxite brick, aluminacarbon, aluminamagnesia and magnesiacarbon bricks. while the use of recycled aggregate in magcarbon bricks is now common practice, according to bradley the level of free metals remaining from antioxidant
