The invention relates to a metal product quenching medium cyclic utilization device. The device comprises a heating furnace, a spray chamber, an infiltration groove, an elution chamber, a liquid storage tank, a quenching groove and a melting convergence groove, wherein a liquid conveying pipeline is arranged between one end of the insulating furnace door of the heating furnace and a water pump inthe liquid storage tank; a spray water conveying pipeline is arranged between the other end of the insulating furnace door and the spray chamber; the melting convergence groove is arranged above the quenching groove; a spray water splash guard is covered in the melting convergence groove; the spray water splash guard is provided with a splash-proof cover plate; a spray water branch is divided from the spray water conveying pipeline at the position of the melting convergence groove; the branch is communicated with the melting convergence groove; an electromagnetic valve is added on the spray water branch; a temperature controller is connected with the quenching groove; and a medium conveying pipeline, a medium reflux pipeline, the melting convergence groove and the quenching groove constitute a medium circulation circuit. By using the device of the invention, the recovery and cyclic utilization of the medium are both performed in the melting convergence groove automatically, the procedures of medium recovery are reduced to the minimum, the operation is safe; and the medium can not be wasted and the environment can not be polluted.
