Project Description
| Product Name | Fired Magnesia Brick |
| Description | SH-MZ SERIES, is made from high quality magnesia ore of different MgO Content. The engineering of higher MgO content and burning temperature delivers more periclase crystal direct bonding of the products, better corrosion resistance and achieving better performance.
SH-DMZ SERIES is Electro Fused Magnesia brick is made of fused magnesia with large periclase crystal, High bulk density, low apparent porosity. It performs well at high temperature volume stability, high temperature strength and slag resistance. |
| Application | Ø Safety Lining of steel making furnaces Ø Working lines of hot metal mixers, Ferroalloy Smelting Furnaces Ø Non-ferrous metallurgical furnaces, Preheating zones Ø Cooling zones of lime kilns, Glass tank regenerators |
