Method for Manufacturing Metal Filter Using Metal Scrapped Materials

PURPOSE : Provided is a method for manufacturing metal filter being capable of filtering fine dust and being advantageous in productivity and quality by performing stacking and calcining processes continuously. CONSTITUTION : The method comprises the steps of shaping metal waste to a certain feature while eliminating polishing oil from metal waste by pressurization, removing the polishing oil in the metal having a feature under vacuum state, crushing the metal and sorting metal fractions, forming metal slurry by mixing the metal fractions and binder, putting the metal slurry onto a metal mesh, drying the slurry, performing post process, such as trimming, grooving and corrugation, the metal slurry-coated metal mesh to increase filtering surface area, and calcining the post-processed product.
