Alumina Magnesia Carbon Bricks

With a sole aim in delivering quality products, we are the prominent Manufacturer, Exporter & Supplier of Alumina Magnesia Carbon Bricks in Zhengzhou, Henan, China.
Aluminum-magnesium carbon brick is a new variety developed in recent years, based on the aluminum-magnesium brick and magnesium carbon brick, and its production process is mostly like magnesium carbon brick. It is made of Al2O3, MgO and C as the main components, Containing Al2O3 of 60% ~ 69%, Mgo of 7% ~ 14%, C of 5% ~ 12%.
Aluminum-magnesium carbon brick(Water glass bonded) use Level one or two bauxite clinker for refractory aggregate, Level one or special high-aluminum powder for refractory powder, and blended 8% to 13% the first and second grade metallurgical magnesia powder. Carbon material use electrode powder, earth-like graphite or flake graphite, the amount of 3% - 8%, use water glass solution (m = 2.4 ~ 3.0) as a binder, after forming treated in 200 ~ 250 a low temperature after forming, the brick is finished.
Features of Alumina- magnesium carbon brick:
1. good resistance to slag erosion
2. thermal shock resistance
3. low rebirth line expansion.
In order to improve its oxidation resistance, Si powder, Al powder, SiC powder or ferrosilicon powder can be added in the ingredients, use resin as binder, molding in high pressure. It can be used after 200 ~ 300 a treatment, without Calcined.
