Description: In the casting process, molten metal filtration and purification is to ensure that the inherent quality of the casting indispensable part. The product can effectively filter the liquid metal, which has a mesh opening of the structure, high porosity, large surface area of the slag can be set, the flow of metal through the filter of the zigzag line, large particles are separated out fine particle impurities filter pore walls were adsorbed, and then to improve casting quality, reduce scrap purposes.
