Brown Aluminium Oxide 54 Grit Suppliers South Africa

In view of the above factors, the penetration and erosion of slag are restrained(brown aluminium oxide). When the chromium oxide is added to the sample, the oxide mark is dispersed in the matrix. At high temperature, CrO2 is dissolved in Al2O3 to form a completely eutectic solid solution, which absorbs Fe2O3 in steel slag(aluminum oxide abrasive). Cr2O3 is dissolved in Spinel to form composite spinel, and the chromic spinel in the permeable layer absorbs Fe2O3.

According to the physical properties of corundum spinel permeable brick added with oxide inscription before(white alumina), when the content of the sample is 1%, the physical properties at room temperature are relatively optimal. At the same time, Cr2O3 is dissolved into magnesia alumina spinel to form composite spinel solid solution containing chromium(white aluminium oxide powder), which makes the linear change rate of the sample increase.(brown aluminium oxide 54 grit suppliers south africa)


If too much chromium oxide is added(silicon carbide abrasive), forming too many fully eutectic solid solutions, inhibiting the absorption of Fe2O3 into steel slag, thus reducing slag resistance and not improving slag corrosion. The effect of chromium oxide content on the properties of corundum spinel permeable brick was studied(aluminum oxide grit). Considering the above factors, the performance of the sample is the best when the amount of chromium oxide is 1%.


(brown aluminium oxide 54 grit suppliers south africa)The experimental results show that after heat treatment at 1100 ℃ for x4h, with the increase of oxide content(brown fused alumina), the bulk density of the sample increases gradually, the porosity decreases, and the flexural strength and compressive strength increase gradually; After heat treatment at 1600 ℃ for x4h, Cr2O3 will be dissolved in Al2O3 easily(synthetic corundum), the mechanical properties of the samples are the best when the amount of chromium oxide is 1%.


When the content of chromium oxide is 1% ~ 5%(black corundum), with the increase of chromium oxide content, the bulk density of the sample increases slightly, the change of porosity is not obvious, and the flexural strength and compressive strength decrease gradually. After heat treatment at 1100 ℃ for x4h, the linear change rate of the sample without adding chromium oxide is the largest(green silicon carbide), and the sample shows expansion phenomenon.(brown aluminium oxide 54 grit suppliers south africa)


At the same time, spinel is not easy to react with calcium and silicon in steel slag, so as to reduce the corrosion reaction between slag and sample(brown aluminum oxide). With the increase of chromium oxide content, the linear change rate decreased. After heat treatment at 1600 ℃ for X 4h, the sample shows expansion phenomenon(emery abrasive). For the sample with chromium oxide, the linear change rate increases with the increase of chromium oxide powder.


(brown aluminium oxide 54 grit suppliers south africa)The content of Cao, SiO2 and Fe2O3 in the substrate of the reaction layer is reduced sharply(pink corundum), which not only inhibits the penetration of slag, but also reduces the corrosion reaction between slag and sample. The slag erosion of the sample without adding chromium oxide is more serious and the slag permeability of the sample is poor(black silicon carbide). With the increase of chromium oxide content, the slag penetration resistance of the sample increases.
