About zirconium corundum refractory brick tilt casting method: tilt casting method is to cast the mold at an angle before casting, and put the riser on one end of the mold for casting, so that not only can get a dense area in the T part, but also can use the ordinary mold to get higher accuracy in the T direction. Therefore, when the wall of the pool is built with this casting, its height can be used.

Therefore, when the wall of the pool is built with this casting, its height can be used.
Casting without shrinkage cavity (code: China WS, Corning VF, Xu VF, Toshiba DCL, casting, concentrating shrinkage cavity in a certain area, removing it with diamond saw after annealing, the remaining useful part is uniform in composition, compact in structure, and its average volume density is close to theoretical density; The other is cutting and casting leg method: starting from reducing the cutting area, casting the casting into "L" shape, the majority of the shrinkage cavity is concentrated on the smaller leg of "L", which accounts for 60% of the total volume of the casting. The whole casting is buried in the insulation material during annealing and is kept inclined to promote the shrinkage cavity to concentrate on the leg.
This process due to the high cost of cutting-diamond saw cutting costs are generally higher than the price of the casting body, Gu only used in individual cases.
Zirconium corundum mullite wear-resistant bricks are made of zirconium corundum and mullite as the main raw materials by high-pressure molding and high-temperature sintering. The thermal shock stability, wear resistance and chemical attack resistance of the product are very good. Products are widely used in CFB boiler ignition systems and other industrial furnaces.
