Another important reason for the formation of shrinkage cavity is that the bulk density of fused corundum brick is greatly reduced during melting, resulting in large volume shadow expansion(white fused alumina). Slow cooling method for tunnel preparation: remove the mold on the kiln car, and immediately push the kiln car into the high temperature part of the tunnel kiln(aluminum oxide grit). The temperature is kept at 1300-1400 ℃ for 2-4h, then cooled at 15-60 ℃ / h, and cooled naturally below 800 ℃.

The yield of fused A-B corundum brick can reach more than 80% by controlling the cooling rate(white aluminum oxide). The former Soviet Union produced KOP93 and KOP-95 fused cast corundum brick (600mm × 300mm × 200mm) for rapid cooling. Because of the high hardness and good wear resistance of fused alumina brick, the diamond cutter should be used in cutting and grinding(synthetic corundum). The semi submerged arc method is used to stop feeding when the stack is full of molten materials.

(aluminum oxide sandblast media wholesale price belgium)The technological parameters of cutting and grinding are as follows(white corundum): the moving speed of the working table of the machine tool is 19.6r/min, the vertical feed of the grinding tool is 0.3-0.6mm/min, the cooling water consumption is 20L / min, the unit energy consumption of cutting and grinding materials is 1.5kw · H / kg (4.4kw · H / DM), the productivity of the machine is 68em / min(steel grid), and the unit consumption of diamond is 0.5 carat / kg (L.4 carat / DM).

Raw material, low alkali primary industrial alumina(silicon carbide abrasive). Air compressor: Volume 10m / min, pressure 0.78mpa. J0-20kg is added each time, with an interval of 5-10min. The melting point of alumina is 2050 ℃, and the temperature suitable for ball blowing should be 200-300 ℃ higher than the melting point, i.e. it needs to be heated to 2200-2300 ℃(garnet suppliers). If the temperature of the melt is low and the viscosity is large, it is easy to blow into a thick wall ball or honeycomb hollow ball.

For industrial use, in powder form(green silicon carbide). For example, the true density of corundum brick is 3.99g/cm, but when alumina melts at 2052 ℃, the bulk density is only 2.98g/em, and the molar volume of the melt increases obviously, its increasing value is 23.5%, and with the increasing of melting temperature, its density continues to decrease(emery abrasive). The distance between nozzle and liquid flow is 30-50mm, and the angle between nozzle and liquid flow is 80-90.(aluminum oxide sandblast media wholesale price belgium)

Electric melting equipment, using 0.5T steel-making three-phase arc furnace supporting system (650kV · a transformer(black silicon carbide), automatic control part). Automatic control electrode lifting part). The tilting movable furnace shell is made of graphite block or graphite enrichment as furnace material, and the alumina hollow ball (in the specification of graphite crucible collapse) is filled between the furnace shell and graphite furnace lining(garnet abrasive). 500mm, 350mm, 250mm high and 200mm deep).

(aluminum oxide sandblast media wholesale price belgium)A graphite launder shall be set between the graphite sizing and the furnace shell, and the launder shall extend 100-150mm out of the furnace shell(aluminum oxide abrasive). A compressed air nozzle (with a rectangular nozzle opening of 50mm × 5mm) shall be fixed on the furnace shell under the launder(glass bead blasting media suppliers). First, lay the furnace bottom (thin in the middle and thick around) with industrial alumina or recycled materials, and add carbon blocks on the top.
