What Is Corundum Brick Used for?

The use performance of corundum brick refers to the https://cheapfirebricks.com/corundum-brick/ has the performance when used inhigh temperature. Including refractoriness, refractoriness under load, linearchange rate, thermal shock resistance, slag resistance, acid resistance, alkaliresistance, oxidation resistance, resistance to hydration and CO erosionresistance, etc.

High Quality Corundum Brick In RS

1.Increase the refractoriness.
Refractoriness refers to corundum brick with non-melting performance under resistance tohigh temperature. Refractoriness is the basis fordetermining material whether can be used as a refractory brick. The international standardization organization stipulates above 1500 ℃ refractoriness of inorganic non-metallic materials is the refractory material.The significance of refractoriness and melting point is different. Can not take refractoriness as the use of corundum brick temperature. The basic factor of refractoriness to decide is chemical mineral compositionand its distribution of corundum brick.

2.Increase the refractoriness under load.
Corundum brick refractoriness under load refers to the products bear constant load deformationtemperature under thecondition of rise temperature. It shows corundum brick the ability of resistance to high temperature and load effect, to a certainextent, indicates that products in the similar conditions of use case structurestrength. The major factors that affect corundum brick refractoriness underload is the chemical mineral composition and microstructure. To improve thepurity of raw materials, reduce the content of low melting or flux, increasethe molding pressure, made of high density of bricks, can significantly improveproducts refractoriness under load.

3. Improve the thermalshock resistance
Thermal shock resistance refers to the corundum brick with damage resistanceperformance to the temperature change rapidly. Generally speaking, the thermal expansion rate of corundum brick isgreater, thermal shock resistance is worse. The thermal conductivity ofproducts is higher, thermal shock resistance is better. In addition, theorganization structure and grain composition shape and other productsof corundum brick have effect on the thermal shock resistance.
