Technical Field

[0001] The utility model relates to the technical field of heating furnaces, in particular to a heating furnace with uniform heating. Background Art

[0002] In the metallurgical industry, a heating furnace is a device that heats materials or workpieces (usually metals) to rolling or forging temperature. Heating furnaces are used in many industries such as petroleum, chemical industry, metallurgy, machinery, heat treatment, surface treatment, building materials, electronics, materials, light industry, daily chemicals, and pharmaceuticals.

[0003] The key unit of the heating furnace is the heating tube, which is responsible for heating up to high temperature for preheating. However, the position of each heating tube in the heating furnace must be checked repeatedly before use to prevent collision caused by vibration and reduce accidents.

[0004] In the prior art, a Chinese patent with a publication number of CN208468805U is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a heating furnace, comprising a frame, a mesh disk, a mesh disk operation unit, a heating element, and a temperature control system. The frame is an integral frame structure shell, a thermal insulation layer is fixedly arranged in the frame, and a heating element fixing assembly is arranged on the top wall of the thermal insulation layer. The heating element fixing assembly is formed by splicing and connecting a top connecting plate and a bottom connecting plate with each other, wherein a groove and a fixing bracket are arranged on the top connecting plate, the fixing bracket is located in the groove, and a frame-shaped convex portion is arranged on the bottom connecting plate, and a heating element consisting of a reflector and a plurality of heating tubes fixed in the reflector is arranged in the frame-shaped convex portion. When splicing, the frame-shaped convex portions are embedded in the groove, and the fixing bracket is against the reflector. A mesh disk is arranged in the middle of the interior of the frame, and the mesh disk is driven to extend in and out by the mesh disk operation unit. The mesh disk operation unit is fixed on the front wall of the frame, and a temperature control system is arranged on the wall of the frame. The utility model provides a heating furnace which is safe and reliable, and its heating element is easy to disassemble and assemble. However, after the workpiece is heated, the temperature of the workpiece itself is very high. If the user directly takes the workpiece, it may cause burns, which is dangerous.

The user can turn on the fan 302 to cool the workpiece, and the hot air can be discharged through the heat dissipation window 102, thereby avoiding the user from directly taking the heated workpiece and being burned, thereby protecting the user.

[0047] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention.
