Product Description

Burnt magnesia brick/Magnesia brick for electric furna/High softening under load,Strong resistance to metallurgical slag

 

Product description:

The international standard iso1109-1975 specifies that alkaline products with MgO≥80% are magnesia bricks.Asma standards.


Category of Refractory Brick/Fire Brick:

In the classification of magnesia bricks, magnesia bricks are divided into three grades according to the MgO content: 90, 95 and 98. The minimum MgO content of corresponding grades is 86%, 91% and 96%, respectively.According to the different production technology, magnesia brick is divided into fired magnesia brick, not burned magnesia brick and combined magnesia brick.


Features:

Burnt magnesia brick, usually referred to as burnt magnesia brick, magnesia brick, is the largest production, the most widely used alkaline brick.China magnesite is of good quality and abundant reserves, and magnesite brick is of good quality and cheap price.The fire resistance of magnesia brick reaches above 2000℃, and the initial temperature of softening under load is Between 1520℃ and 1600℃, while high purity magnesia brick can reach 1800℃.Magnesia brick is widely used in the permanent layer of steel industry converter, electric furnace, iron water tank, glass kiln, etc.

The Magnesia brick provided by XinYu Refractory has the advantages of high strength,corrosion resistance and high temperature resistance.
