The utility model discloses a quenching heat recovery device for a heat treatment line, which comprises a quenching tank filled with quenching liquid. At least one heat exchanger is mounted on at least one of the four sides of the quenching tank, each heat exchanger comprises a case fixed onto the lateral side of the quenching tank, and a water pump is mounted on the upper cover of each case. When high-temperature work pieces enter the quenching liquid, lost heat is taken by the quenching liquid and dissipated through liquid surface and four walls of the quenching tank. The heat exchangers are used for recovering heat to heat devices using heat energy, and thereby energy-saving effect is achieved.
