Honeycomb Ceramic Plate for casting and gas filter
Honeycomb Ceramic Plate for casting and gas filter
Honeycomb ceramic filter apply to metal liquid filtration, it is made by material of mullite or cordierite ceramics. With unique high-density straight-pore honeycomb structure, excellent thermal shock resistance, high strength, high porosity and specific surface area. Thereby to improve its adsorption and capturing tiny impurities ability, as to get rid of non-metal impurity and gas, purify metal liquid, make the metal liquid steady and reduce the vortex. It not only reduces the defective index of the casting, prolong the working life of the casting and reduce the casting cost, but also improve mechanic capability and appearance quality of the casting.
Ceramic honeycomb filter is extensively applied to the metallurgic plants of casting and foundry, such as steel, iron, copper and aluminum, etc. It has high mechanical intensity and heat-resistance, removing the metal impurity, refractory scrap, solid refractory alloy and sinter in the molten metal liquid.
