White Fused Alumina For Precision Casting Philippines

The experimental results show that: after heat treatment(120 grit aluminum oxide), the bulk density of the sample increases with the increase of the amount of monoclinic oxide drill, which is mainly due to the high volume density (56gcm) of monoclinic oxidation fault. When the amount of monoclinic oxidation is 1 ~ 4%, the change of porosity is not obvious after heat treatment at 1100 ℃ for x4h(150 grit aluminum oxide), but it decreases slightly after heat treatment at 1600 ℃ for x4h.

With the increase of the amount of calcium stabilized oxide, the bulk density of the sample increases, but the porosity changes little after high temperature treatment(brown fused aluminum oxide). After heat treatment at 1100 ℃ for x4h, the compressive strength and flexural strength of sample G are 96mpa and 16MPa respectively(120 grit aluminum oxide blasting media). After heat treatment at 1600 ℃ for x4h, the flexural strength of sample G is 41mpa and the compressive strength of sample G2 is 144mpa.


(white fused alumina for precision casting philippines)Considering the strength, linear change rate and other factors, when adding 1% monoclinic oxide or 1% calcium to stabilize oxidation, the properties of the sample reach the best(black corundum). Adding proper amount of Cr2O3 into the permeable brick of ladle can significantly improve its slag resistance(steel grid). After heat treatment, the linear change rate of the sample increases with the increase of the amount of monoclinic oxidation dislocation.


According to various factors, the properties of corundum spinel permeable brick are not improved by introducing miscalcite(garnet suppliers), while the properties of corundum spinel permeable brick are improved by introducing monoclinic oxide and calcium stabilized oxidation anchor. The microstructure photos of go and G after heat treatment at 1600 ℃ for x4h were taken(100 grit aluminum oxide blast media). When the amount of calcium stabilized oxidation error is 1%, the linear change rate of the sample is small.(white fused alumina for precision casting philippines)


With the increase of heat treatment temperature, when the amount of monoclinic oxidation fault in the sample is 1%, the mechanical properties are the best(pink aluminum oxide). When the amount of monoclinic oxidation is 1% ~ 4%, the erosion and melting loss of slag and the structural spalling of modified layer formed by slag penetration are also important factors in the damage process of permeable brick(brown fused aluminum oxide manufacturers), and the corrosion resistance of slag is significantly enhanced.


(white fused alumina for precision casting philippines)After heat treatment, the strength of the sample decreases obviously with the increase of the monoclinic oxidation drill(garnet abrasive). The reason is that Cr2O3 enters into the slag and the reaction products of slag matrix, which increases the viscosity of slag and forms high viscosity liquid phase covering the surface of reaction layer(aluminum oxide blast media 60 grit), which prevents the continuous penetration of slag into the sample and reduces the corrosion rate of the sample.


With the development of permeable brick(glass bead blasting media suppliers), a small amount of chromium oxide is introduced to further improve the performance of corundum spinel permeable brick. Because the melting point of glass oxide is 2275 ℃, which is higher than that of Al2O3 (2050 ℃), alumina and chromium oxide can form a continuous solid melt(low sodium white fused alumina). A lot of work has been done on the introduction of chromium oxide into the porous brick of ladle.(white fused alumina for precision casting philippines)
