Continuous casting blank on-line continuous quenching equipment and continuous casting blank on-line continuous quenching process

The invention discloses continuous casting blank on-line continuous quenching equipment and a continuous casting blank on-line continuous quenching process for quenching a casting blank on the production line of continuous casting equipment. The continuous casting blank on-line continuous quenching equipment comprises a quenching roller way, a water tank and a water inlet pipe, wherein the water tank is arranged along the drawing direction of the casting blank; the quenching roller way is positioned in the water tank; the water inlet pipe is communicated with the water tank; two ends of the water tank are both provided with end part sealing parts, the two end part sealing parts are respectively provided with a casting blank inlet hole and a casting blank outlet hole, and the end part sealing parts are closely attached to the outer surface of the casting blank. The continuous casting blank on-line continuous quenching equipment disclosed by the invention can be used for fast and forcibly reducing the temperature of the surface of the casting blank to be less than 600 DEG C before the continuous casting blank is cut and carrying out one-line continuous quenching on the surface of the casting blank by arranging the water tank on a feeding roller positioned between a tension leveler and a flame cutting machine, can well complete the quenching process of the casting blank which needs to be treated in a continuous casting process and has the characteristics of small investment, simple structure, convenient later maintenance and high practicability.
