2% Apparent Porosity Fused Alumina Block for Glass Kiln Lip Stone Brick High Purity

Description of Fused alumina block jargal block for glass kiln lip stone brick

Fused alumina block jargal block for glass kiln lip stone brick is made by melting alumina in an electric arc furnace and casting them into a model of a specified specific shape, annealing and heat preservation, and then processing diamond abrasive tools to obtain the desired product.

Fused alumina brick also called fused corundum blocks mainly refer to fused a, β corundum and fused β corundum blocks. It is mainly composed of 92% to 94% AL2O3 corundum crystal phase, with a density of 2.9 to 3.05g/cm3 . The highest operating temperature is around 1700℃. Fused alumina has very good resistance to glass leakage and hardly pollutes the glass liquid. It is widely used in the working part tank wall, tank bottom, flow channel, working part forehearth tank wall, forehearth tank bottom, etc. of the glass melting furnace that are in contact with the glass liquid and are required to be free of refractory material contamination.

The fused alumina brick has good high temperature volume stability and corrosion resistance.

α-β Al2O3 Fused alumina brick have the characteristics of α-Al2O3 and β-Al2O3 Fused alumina brick. The main crystal phases are directly combined, and the composition contains only a small amount of glass phase. The crystal structure is compact, the porosity is low, the high temperature wear resistance is good, the mechanical strength is high, and it has good high temperature resistance to alkali vapor stability.

For Fused alumina brick, the viscosity of the nepheline metamorphic layer generated on its surface in the glass liquid is not as high as that of the nepheline metamorphic layer containing ZrO2. It is relatively easy to melt, so its corrosion resistance at high temperatures is not as good as that of fused AZS blocks. However, the greater the difference in viscosity between the debris flowing into the glass liquid and the glass liquid, the more difficult it is to dissolve and eliminate. The nepheline metamorphic layer of alumina blocks has a small viscosity and is easily soluble in the glass liquid, so the pollution to the glass liquid is small.

β-Al2O3 fused cast blocks are suitable for the upper structure of the working pool of the glass melting furnace and the combustion port at the back of the melting zone and the breast wall and small furnace flats nearby. The composition of α, β-Al2O3 fused cast blocks contains only a small amount of glass phase, which will not ooze out and pollute the glass melt during use. It is ideal for the cooling part of the glass melting furnace, the bottom of the furnace, and the float glass furnace launder. Furnace building materials, usually used parts are stout brick, lip brick, gate brick.
