Description

Technical Field

[0001] This application relates to the field of heat energy recovery technology, and more specifically, to a high-efficiency energy recovery and energy-saving device for heating furnaces. Background Technology

[0002] During production, the steel billet is transported to the rolling mill by roller conveyor after exiting the heating furnace. During this period, the billet travels about 200m. Since the billet exits the furnace at a temperature of over 800℃, it continuously dissipates heat to the outside during transportation, increasing heat loss. Summary of the Invention

[0004] This application provides a high-efficiency energy recovery and energy-saving device for a heating furnace, including a conveyor roller, heat insulation plates disposed on both sides of the conveyor roller, and heat exchange tubes disposed on the heat insulation plates.

[0005] Preferably, the heat exchange tube has a serpentine structure.

[0006] Preferably, the heat exchange tube has a plurality of fins on its outer wall.

[0007] Preferably, the fins have a spiral structure.

[0008] Preferably, a support plate is provided at the bottom of the heat insulation plate.

[0009] Preferably, a plurality of reinforcing plates are provided between the heat insulation plate and the support plate.

[0010] Preferably, the heat exchange tube is made of stainless steel.

[0011] The beneficial effects of this utility model are:

[0012] The high-efficiency energy recovery and energy-saving device for heating furnaces provided by this utility model has the characteristics of simple structure, convenient manufacturing, easy installation and use. The device is applied next to the billet conveying roller. When in use, the conveying roller transports the billet from the outlet end of the heating furnace to the inlet end of the rolling mill. During the conveying process, the billet will continuously dissipate heat to the outside. Heat exchange medium is introduced into the heat exchange tube to recover the heat dissipated by the billet through heat exchange, thereby reducing the waste of heat energy and improving the utilization rate of heat energy.
