Abstract

Plant is used to remove mold residues from castings by high voltage discharges in a liq., e.g. water. A double chain conveyor, fitted with loading and unloading devices, carries the castings continuously through a zone (a) in the water bath; and the number of electrode units located in the treatment zone (a) is the same as the number of castings travelling through zone (a). The electrode units are pref. hinged on the conveyor frame so the electrode tips move together with the castings through zone (a), while driven gear wheels mounted on one side of the bath use grippers to rotate the castings while they travel through zone (a), i.e. so all the surface of each casting is treated to the electric discharge. Used esp. in mass prodn. to remove the residues of shell moulds from the castings, together with ingates, scale, rust, oil, etc., thus polishing the castings.
