Abstract

A method for recovering substance such as zincing or the like adhered to the surface of an object to be processed, by causing such materials to be evaporated in a vacuum. In this method, the object to the processed is placed in a furnace provided with heating means; the temperature within the furnace is elevated up to a predetermined level with the aid of an oxidizing gas atmosphere; the pressure in the furnace is reduced so that the quantity of the oxidizing gas is reduced to be below the explosion limit; and a reducing gas atmosphere is fed into the furnace to reduce the oxidization of the object to be processed. Thereafter, the interior of the furnace is evacuated while being maintained under a predetermined evaporation temperature condition; and the substance evaporated from the object to be processed is passed to recovery means provided in communication with the furnace, so that the substance thus evaporated is condensed in the recovery means and recovered therefrom.
