Application status of low carbon magnesium carbon brick
Anti-oxidation and anti-corrosion new low-carbon magnesium carbon bricks are more suitable for today’s society, and the low-carbon economic development requirements generally advocated worldwide. The new low carbon magnesium carbon brick has been widely used in a series of production processes such as refining Baotou Steel due to its inherent characteristics of corrosion resistance and oxidation resistance.
Compared with the traditional graphite and magnesia-magnesia bricks, the new low-carbon magnesia-carbon bricks have made a certain degree of adjustment in the proportion of graphite and magnesia. In the new low-carbon magnesium-carbon brick, magnesia with large crystalline state and natural graphite with a carbon content of nearly 100% are used as the main raw materials for making the magnesium-carbon brick. On the basis of magnesia and carbon content, an appropriate amount of powdered aluminum and silicon are added as antioxidants of the new low-carbon magnesium carbon brick. Resin is used as the adhesive bonding agent of low carbon magnesium carbon brick.
The low-carbon magnesium carbon brick produced by this production combination method is far higher than the traditional coal bricks in terms of the corresponding oxidation and corrosion resistance and the service life of the magnesium carbon bricks. The service life of the new low carbon magnesium carbon brick can even be extended by a quarter on the basis of the service life of the traditional magnesium carbon brick.
However, in the production and application process of new low carbon magnesium carbon brick, a series of disadvantages and problems will inevitably occur. Thermal shock stability and slag resistance are generally reduced, which are the most common problems in the application of new low-carbon magnesium carbon bricks, because the carbon content of new low-carbon magnesium carbon bricks has been greatly reduced. Affected by the low carbon content of magnesia-carbon bricks, the corresponding heat transfer performance also showed a significant downward trend.
A series of disadvantages require more in-depth research and exploration by relevant scientific research staff.
All in all, compared with traditional magnesium-carbon bricks, the new low-carbon magnesium-carbon bricks far exceed the development level of traditional magnesium-carbon bricks in terms of energy saving and environmental protection capabilities, as well as specific application performance.
If the new low-carbon magnesium carbon brick is to be better applied in the corresponding production and life, relevant staff must continue to conduct in-depth research and analysis on the application of the new low-carbon magnesium carbon brick. Only continuous exploration, change and innovation can finally improve the application efficiency of new low carbon magnesium carbon bricks.
