Feature of Our refractory magnesia bricks
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.
7. Hydrability, keep product away from moisture during storage.
