[0009] Furthermore, a heat-insulating layer is provided in the heat treatment box, which can reduce energy consumption and avoid excessive temperature difference between the inside and outside of the high-temperature resistant conduit; and an oblique through hole is provided on the side wall of the heat treatment box.

[0010] Furthermore, the high temperature resistant conduit is a high temperature resistant ceramic tube;

[0011] The two ends of the high temperature resistant conduit are respectively arranged on the heat treatment box through support sleeves.

[0012] Furthermore, the side wall of the quenching tank is provided with a liquid inlet pipe for replenishing the quenching liquid, and a liquid discharge pipe is provided at the bottom thereof, so that the quenching liquid can be replaced according to specific needs.

[0013] Furthermore, the quenching pool is a special-shaped structure, and its depth close to the high-temperature resistant pipe is greater than its depth away from the side thereof, so as to adapt to the inclined structure of the inclined conveying mechanism.

[0014] Furthermore, the horizontal conveying mechanism is a horizontal conveyor belt.

[0015] Compared with the prior art, the beneficial technical effects of the utility model are as follows: in the present application, a high-temperature resistant conduit is obliquely installed in the heat treatment box as a channel for connecting the chain rings, and a quenching heating coil outside the high-temperature resistant conduit is used to complete the quenching treatment of the connecting chain rings during the sliding process, and slide into the quenching pool for cooling, wherein the connecting chain rings in the quenching pool can also be salvaged and transported by an inclined conveying mechanism, thereby facilitating the realization of automated heat treatment processing.
