Magnesia carbon brick is made of magnesia and carbon materials, and various non-oxide additives are added. Magnesia carbon brick is a kind of basic refractory material. As a composite refractory material, magnesia carbon brick effectively utilizes the slag erosion resistance of magnesia and the high thermal conductivity and low expansion of carbon.
The main characteristics of magnesium carbon bricks
- Magas hőmérsékleti ellenállás: Mag carbon bricks have a high softening point, usually at 1900-2000°C, which can meet the high-temperature requirements of most industrial production
- High slag resistance: Magnesia carbon bricks can react with various metal slags at high temperatures to form a protective layer, cutting off the further reaction between slag and bricks, so they have high resistance to slag erosion, especially suitable for slag content Large and complex occasions.
- Low water ingress rate: Magnesia carbon bricks have high density, almost no water absorption, good water resistance, and will not be damaged by water.
- Hőütésállóság: The softening point of magnesia carbon bricks can reach above 1900°C, and the service temperature range is very wide, which can be used in most industrial furnaces.
