Huachen Refractory
Forsterite brick and Magnesite dolomite brick are both basic refractory bricks. They are not widely used. However, based on their own advantages, they are applied in specific fields, such as glass kiln regenerator and convertor.
Forsterite brick introduction
Forsterite brick is a basic refractory brick mainly composed of magnesia and silica. Among refractory bricks based magnesia, its resistance to high temperatures is not particularly outstanding. Its refractoriness under load just exceeds 1600 ℃, the apparent porosity is 20% around, and the bulk density is only 2.7g/cm3. Its advantage is excellent thermal shock resistance. It is most commonly used as checker brick in condensation zone of a glass melting kiln regenerator. Especially in large float glass kiln, it is widely used. It is also called magnesite olivine brick.
Magnesite dolomite brick introduction
Magnesite dolomite brick is a basic refractory brick produced using calcined dolomite sand as main raw material. It is most commonly used as lining bricks in alkaline oxygen convertor. Because CaO content is relatively high, it is also called magnesia calcium brick.
