The heat of the molten aluminum causes the jaws to quickly rise to near the metal temperature. The overturning plate is instantaneously heated and swells. This requires that the overturning plate should have a small coefficient of thermal expansion and should not crack after being heated; it is also impregnated with aluminum. The male plate in the liquid must last for a certain period of time, and it is not allowed to be washed and softened and deformed during work. The industrial test proved that the foam ceramic filter plate developed by us has good filtration performance and good heat spread performance, achieving the intended purpose.
The chemical resistance of the filter plate is better not to react with aluminum at high temperatures. Skeleton material selection Polyurethane flexible foam is the key material for making foam ceramic filter plates. It should have a uniform eyelet, a reasonable number of meshes, good elasticity, and can be fully restored to original shape after pulping. In the trial production we used 20 to 25 mesh flexible foam.
The control of the weight of porcelain paste has a great influence on the strength and through-porosity of the product. There are too many porcelain pastes on the foam, although the strength has been increased, but the through-hole rate is too low to cause waste. Therefore, accurate control of the weight of the porcelain paste is a condition for ensuring the quality of the product. Tests have shown that using empirical relationships can accurately determine product weight. Experiments on the degree of drying and the effect of the dry bath method on strength and other tests showed that the drying temperature and method have a great influence on the ceramic plate. Drying methods can usually be divided into natural, forced, and temperature methods. We have chosen the forced method, which has a uniform drying speed, fast drying speed, and no traces of dross cracks. This method reduces or basically eliminates the waste that appears in the drying process, and the product is smooth. The drying temperature is too high, the reaction speed of porcelain slurry is accelerated, the hardening speed is too fast, one causes local cracking, and the strength is reduced; second, the deformation of the product is increased, resulting in waste products, and the optimum drying temperature is 15 to 35°C.
