Low Price Aluminum Oxide 20 Grit Suppliers Germany

The quality of chrome corundum permeable brick has an impact on the cleanliness of steel, so its performance needs to be further improved. Moreover, chromium is a heavy metal, which is toxic and will cause certain pollution to the environment(artificial corundum). There are dozens or even more straight through circular holes or connected circular holes through which the gas can be blown through the circular holes to achieve argon blowing effect.

Electrofused tabular corundum is a kind of tabular corundum formed in semi molten state in an arc furnace at 1900-2000 ℃ using industrial alumina as the main raw material(silicon carbide abrasive). Corundum material refers to refractories with more than 90% Al2O3 content(synthetic corundum). In addition, the volume of the refractory at the bottom of the ladle will also change accordingly, which is due to the penetration of the ladle There is a temperature gradient in air brick refractories.(low price aluminum oxide 20 grit suppliers germany)


The thermal stress damage of the air brick is mainly analyzed from the following aspects(glass bead blasting media suppliers): on the one hand, the refractory material on the working face of the air vent brick, especially the refractory around the air outlet, is in direct contact with the high temperature molten steel at 1600 ~ 1700c, at the same time, it is also affected by the continuous blowing out of cold air(silicon carbide 180 grit), resulting in a large temperature gradient, resulting in high stress concentration.


(low price aluminum oxide 20 grit suppliers germany)The argon gas blown out has a certain reverse impact force on the working face of the permeable brick and the refractory materials around it(green silicon carbide); when the argon blowing enters the normal spraying state, the strong entrainment has shear and scouring effects on the permeable brick, thus accelerating the damage of the permeable brick. In addition, the gap operation of the ladle will also cause thermal shock damage to the permeable brick(emery abrasive). Corundum is made of industrial alumina or bauxite after sintering or electrofusion.


The rapid movement of molten steel at the bottom of the ladle makes the gas phase and liquid phase interact with each other to form turbulence(black silicon carbide), which produces shearing and scouring effects on the permeable brick of the ladle. Especially when the air permeable brick is higher than the seat brick, the phenomenon of such coiling shear and scouring is very obvious(garnet abrasive), so that the part higher than the base brick will be washed away after one use.(low price aluminum oxide 20 grit suppliers germany)


High alumina material refers to refractories with more than 48% Al2O3 content(aluminum oxide abrasive), which has the characteristics of high cold and hot strength, good wear resistance, heat shock resistance, spalling resistance and good volume stability under high temperature(garnet suppliers). However, its resistance to slag erosion and penetration is not good enough to resist the infiltration and penetration of slag to brick in the whole service life. Sintered tabular corundum is a kind of impurity with few impurities.


(low price aluminum oxide 20 grit suppliers germany)In addition, if the valve is closed quickly after refining, the reverse impact of molten steel will also accelerate the damage of permeable brick(aluminum oxide grit). The working face of the permeable brick refractory at the bottom of the ladle is in direct contact with high-temperature molten steel(steel grid). Due to the low temperature of the non working face of the permeable brick refractory at the bottom of the ladle, the temperature of the ladle has been changing during the process of the recycling of the ladle.
