Corrosion Resistance Magnesite Refractory Bricks 2.7 - 3.0g/cm3 Bulk Density
1. The products are fused magnesia as main raw material, after a reasonable size distribution, high pressure forming, high-temperature sintering. The product has strong resistance to slag corrosion ability and high temperature dimensional stability. Mainly used in glass furnace regenerator, the upper part.
2. The regular magnesia bricks are made from dense dead burned magnesia that makes the bricks in good refractoriness, corrosion-resistance, and widely used in checker chamber of glass tank, lime kiln, non-ferrous metallurgical furnaces, open heart furnace, iron mixer and EAF of steel-making, and also ferro-alloy furnace, etc.
HengYu Magnesite Refractory Bricks Features
1. High refractoriness, usually the refractoriness is above 2000°C.
2. Refractoriness under load about 1500-1550°C because of poor high-temperature intensity.
3. Strong ability to resist basic (alkaline) slag, can not contact with acid refractory material.
4. Poor Thermal shock resistance, so keep the temperature of furnace stabilized.
5. Poor Volume stability at high temperature, must set aside appropriate expansion joint when laying brick.
6. Strong ability of thermal conductivity, sometime need insulating material.
