High Purity Refractory Magnesite Brick Refractory Fused Magnesite Brick For Lime Kilns
Magnesia bricks are basic refractory bricks. Its magnesia content is from 92% to 97.7%, and cristobalite is as the main crystal phase.Magnesite bricks are generally divided into bonded magnesia refractory bricks and chemical combination magnesia bricks.Magnesia bricks have excellent performance of resistance to alkaline slag,so this kind firebricks are widely used in glass industry, cement industry,steel and iron industry,etc. Magnesia Bricks Advantages • High refractoriness • Good alkali corrosion resistance and slag resistance • High load softening starting temperature • High purity Less pollution to glass liquid • Long service life and high tempreture resistance Magnesia Brick Manufacturing Process The main raw material of magnesia brick is magnesia sand. Sintered magnesia bricks are made of magnesia clinker. After being crushed, batched, kneaded, and shaped, they are fired at a high temperature of 1550 to 1650°C. The firing temperature of high-purity products is above 1750°C. Fused magnesia bricks also belongs to sintered magenesia refractory bricks.Non-burn magnesia bricks are made by adding appropriate chemical binders to magnesia, mixing, molding and drying.

Magnesite bricks are generally divided into two types:
A) Sintered magnesite bricks This kind of magnesia refractory bricks include direct combined magnesia bricks and recombined magnesia bricks, and fused magnesia bricks, which are made of natural magnesia sand and fired at the high temperature of 1650 to 1750 ℃, which will be used in high temperature requirement working environment,like the regenerator part of glass furnace. Fused magnesia bricks are taken fused magnesia sand as raw material and fired in the high tempreture tunnel klin. Some people have an incorrect idea the fused magensia bricks are made by casting method. B) Unburned magnesite bricks This kind of magnesia bricks include chemical bonded magnesia brick and asphalt bonded magnesite brick, which will be used in low temperature requirement working environment.Chemical bonded magnesia bricks are made with some chemical binders through being shaped and dried.
Application
High Purity Refractory Magnesite Brick Refractory Fused Magnesite Brick For Lime Kilns
a) In the glass furnace: grids and heat exchangers of regenerators in the glass furnace, like magnesia checker bricks
b) In the iron and steel industry: steelmaking furnace linings, ferroalloy kilns, and iron mixing furnaces c) In non-ferrous metallurgical industry furnaces, such as copper, lead, zinc, and side furnace linings; d) In the building materials industry, such as magnesia bricks in lime kiln, magnesia spinel bricks in the cement rotary kiln. e) In high-temperature calcining kilns, shaft kilns and tunnel kilns in the refractory manufacturing industry.
