Bar material heating furnace

Abstract

The invention discloses a bar material heating furnace. The bar material heating furnace comprises a furnace body, a conveying device, a combustion device, a heat exchange cycle device and a temperature measuring device. The combustion device heats bar materials in the furnace body by mixing combustion of fuel and air, the movement of the bar materials in the furnace body is controlled through theconveying device, the heating conditions of aluminum bars of various gradients are detected through the temperature measuring device, and high-precision heating controlling is carried out according to the detected temperature; and the heat exchange cycle device recovers excess heat generated by combustion heating to preheat the bar materials. The high-precision gradient heating of the bar materials in the furnace body is achieved through the devices, the heating heat is fully recycled, and the effect of saving fuel is achieved. The bar material heating furnace can be applied in the field of bar material heating.

Description

technical field [0001] The invention relates to the field of rod heating equipment, in particular to a rod heating furnace. Background technique [0002] Aluminum rod heating is a necessary process before extrusion in the production of aluminum profiles. The heat treatment of the aluminum rod should ensure the temperature control. If the temperature is too high or too low, it will directly affect the hardness of the final product. At present, the aluminum rod heating furnaces that appear on the market mainly use the spray guns on both sides of the furnace body to directly heat a single aluminum rod by flame. The aluminum rod heating furnace in the prior art is to extend the temperature probe into the heating furnace to detect the temperature in the heating furnace. Generally, there are shortcomings such as inaccurate heating temperature detection and short service life of the temperature probe. Moreover, during the heating process of the heating furnace The generated high-...

The aluminum rod heating furnace in the prior art is to extend the temperature probe into the heating furnace to detect the temperature in the heating furnace. Generally, there are shortcomings such as inaccurate heating temperature detection and short life of the temperature probe. Moreover, during the heating process of the heating furnace The generated high-temperature flue gas will be directly discharged to the outside of the furnace, and the heat will not be effectively recycled, resulting in waste of heat energy
