Quenching furnace using waste heat fully

Abstract

The invention relates to a quenching furnace using waste heat fully. On the basis of a quenching tank arranged in a quenching chamber, an isothermal tank, an air cooling tank, a washing tank and a discharge platform are arranged sequentially, a manipulator action rail and a manipulator arranged below the manipulator action rail are arranged at the upper side in the quenching chamber, and heated quenching liquid is deployed reasonably through movement of a moving sealing plate, so that quenching operation, as well as isothermal or tempering operation and the like can be carried out in the quenching furnace; and the quenching furnace uses heat of the quenching liquid heated by a workpiece in the quenching tank, so that the waste heat is used fully.

Description

technical field [0001] The invention belongs to the field of heat treatment devices, in particular to a quenching furnace for fully utilizing waste heat. Background technique [0002] The current quenching equipment routinely performs other heat treatment steps after quenching, such as heat preservation, tempering, etc., and since the quenching liquid passes through the quenching of the workpiece during the quenching process, the temperature is greatly increased, and the quenching process needs to be performed again. Liquid cooling or replacement of quenching liquid, resulting in waste of this part of the heat. If the quenching liquid is used to heat the heat treatment step after quenching, this part of the heat can be recovered, and the liquid heating can also make the heating more uniform and stable. [0003] Many existing heat treatments need to avoid the contact between materials and air during the treatment process, so many existing devices are researching on reducing ...

AI Technical Summary

Problems solved by technology

Some existing heat treatment furnaces integrate heating and quenching into one body, but such devices occupy a large area and are relatively expensive

Now there are also some devices that set the heating and cooling devices as the upper and lower structures, and transfer the materials by connecting the two devices through transmission, but the materials are transferred up and down. Due to the existence of gravity, they must be in the upper device. Load-bearing doors are set up, and the safe delivery of materials cannot be guaranteed during material delivery
