Abstract

The invention discloses a device and method for recycling waste heat of a quenching furnace by a suspension line tempering furnace, and relates to the technical field of quenching furnace waste heat recycling. The device comprises the quenching furnace, the tempering furnace and a quenching furnace waste heat recovery device, the quenching furnace waste heat recovery device is arranged between the quenching furnace and the tempering furnace, the quenching furnace waste heat recovery device comprises an induced draft fan, a first induced air pipeline I and a second induced air pipeline, and a first connecting pipeline is fixedly arranged on one side of the quenching furnace through a third branch pipe. According to the device and method for recycling the waste heat of the quenching furnace by the suspension line tempering furnace, the waste heat recycling device of the quenching furnace is additionally arranged, the induced draft fan is connected with the first connecting pipeline and a second connecting pipeline, and the third branch pipe and a fourth branch pipe are used in cooperation, so that smoke heat in the quenching furnace can be guided into the tempering furnace through the first induced draft pipeline, the induced draft fan and the second induced draft pipeline, and secondary use of the waste heat of the discharged smoke is completed; and the waste heat of the discharged smoke of the quenching furnace is introduced into the tempering furnace, so that the heating time of the tempering furnace is shortened, the use amount of natural gas is reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of recovery of waste heat from a quenching furnace, in particular to a device and a method for recovering and utilizing the waste heat of a quenching furnace by a suspension wire tempering furnace. Background technique [0002] The quenching furnace is a furnace that heats the workpiece before quenching. Quenching is to put the workpiece into the furnace and heat it to the quenching temperature above the critical point and keep it for a period of time, then quickly take the workpiece out of the furnace and put it into the quenching liquid (oil or water) for quenching. The heat source of the furnace can use electricity and fuel , the temperature can be measured with a thermocouple. Furnaces that use electricity, gas, and liquid fuels can be automatically controlled and adjusted by instruments. The quenching furnace is used for quenching treatment of aluminum alloy tube, rod and profile extrusion products. B...
