れるようになってきた。[Prior Art] Metal thin plates and foils are manufactured by casting molten metal into an ingot and rolling the ingot. However, if solid impurities such as metal oxides and minute fragments of refractories contained in molten metal are mixed into the ingot, pinholes and surface defects will occur during the process of rolling the ingot into thin sheets, foils, etc. Sometimes. To prevent this, it is necessary to remove solid impurities from the molten metal.
As shown in the above publications, there is a tubular filter material having a structure in which aggregate particles such as silicon carbide and alumina are bonded together with an inorganic binder to form countless fine continuous pores between the aggregate particles.
A filtration device incorporating a filter cartridge constructed by combining a plurality of filters has come to be suitably used.
