Mag Calcium Bricks

Magnesia series bricks are also called basic bricks. The main content is MgO and main raw materials including dead burnt magnesia or fused magnesia.

Thermal shock resistance and hydrated resistance of basic bricks are weak. So basic bricks are generally used to stable temperature zone and when packed, water-proof package are necessary.Besides, we advise the bricks are used as soon as possible, storing time could be 6-12 months at most.

Key Features for Mag Calcium Bricks

Excellent thermal shock stability,Good resistance to structural spalling,Strong resistance to slag penetration,Clean the molten steel,High hot strength and super resistance to basic foreign substance, steel mill slag, Alkaline Oxide. Good for thermal spalling abrasion and liquid metal penetration resistance,High melting point, high thermal conductivity and heat storage capacity. Used in heat storage and preheater plants,Good volume stability and low porosity

Magnesia-calcium brick is a refractory material made of magnesium oxide and calcium carbonate. Due to its unique physical and chemical properties, magnesia-calcium bricks have excellent performance in specific environments and are widely used in the production of steel, cement, glass, chemicals and other fields.

It is widely used in high temperature applications such as furnaces and furnace doors. Since magnesia-calcium bricks themselves have high melting point and thermal conductivity, and are very stable and durable, they perform particularly well in refractory materials such as lining bricks and bottom plates for furnaces and furnace doors. Magnesia-calcium bricks can also be used in high-temperature explosives, rotary kilns, converters, glass kilns and other equipment that require high-temperature stability.

It is also widely used in the chemical industry. For example, in the production of strong acids such as nitric acid, aluminum chloride and hydrofluoric acid, magnesia-calcium bricks can be used to make chemical equipment such as reaction chambers, pipes, coolers, etc., and can prevent acid corrosion.

In the glass industry and metallurgical industry, magnesia-lime bricks also play an indispensable role. In the glass industry, magnesia-calcium bricks can be used to manufacture various refractory ceramic products, such as heat-resistant porcelain glass kiln lining bricks, glass crucibles, glass oscillators, etc.; in the metallurgical industry, magnesia-calcium bricks can also be made into smelting furnaces Lining, casting materials, etc. to meet the needs under high temperature and high pressure.
