1. Increase the refractoriness.
Refractoriness refers to corundum brick with non-melting performance under resistance to high temperature. Refractoriness is the basis for determining 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 composition and its distribution of corundum brick.

2. Increase the refractoriness under load.
Corundum brick refractoriness under load refers to the products bear constant load deformation temperature under the condition of rise temperature. It shows corundum brick the ability of resistance to high temperature and load effect Wholesale C. J. Beathard Jersey , to a certain extent, indicates that products in the similar conditions of use case structure strength. The major factors that affect corundum brick refractoriness under load is the chemical mineral composition and microstructure. To improve the purity of raw materials, reduce the content of low melting or flux, increase the molding pressure, made of high density of bricks Wholesale Reuben Foster Jersey , can significantly improve products refractoriness under load.


3. Improve the thermal shock resistance
Thermal shock resistance refers to the corundum brick with damage resistance performance to the temperature change rapidly. Generally speaking, the thermal expansion rate of corundum brick is greater, thermal shock resistance is worse. The thermal conductivity of products is higher , thermal shock resistance is better, the better. In addition Wholesale Jaquiski Tartt Jersey , the organization structure and grain composition shape and other products of corundum brick have effect on the thermal shock resistance.
