METHOD FOR REPRODUCING CARBONIZING METALIC MATERIALS

摘要

The present invention relates to carbide metal recycling a waste shell. The present invention comprises the steps of: preparing the waste shell (200) (S310); impregnating the waste shell (200) in a separator (S320); withdrawing the waste shell (200) to be dried in the room temperature (S330); impregnating the waste shell (200) in a primary acid treatment agent (S340); withdrawing the waste shell (200) to be dried in the room temperature (S350); impregnating the waste shell (200) in a secondary acid treatment agent (S360); withdrawing the waste shell (200) to be dried in the room temperature (S370); coating the surface of the waste shell (200) (S380); and withdrawing the waste shell (200) to be dried in the room temperature (S390).
