With the continuous advancement of materials science and heat treatment technology, the performance requirements for sintering furnaces are also increasing. Reducing heat loss within the sintering furnace and improving heat utilization efficiency have become urgent technical challenges.

[0022] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0023] Example:

[0024] Refer to the attached Figure 1 and Figure 2 The embodiment provides a structure for reducing heat loss in a sintering furnace, including a sintering furnace body 1, a built-in heat insulation layer 2 is provided inside the sintering furnace body 1, a plurality of No. 1 brackets 3 are fixedly installed between the outer wall of the built-in heat insulation layer 2 and the inner wall of the sintering furnace body 1, and a plurality of No. 1 reflective plates 4 are fixedly installed at equal angles on the outer wall of the built-in heat insulation layer 2.

[0025] Refer to the attached Figures 1-4 A mounting bracket 5 is provided on the outside of the sintering furnace body 1, and several No. 2 brackets 6 are fixedly installed between the outer wall of the sintering furnace body 1 and the inner wall of the mounting bracket 5. Several No. 2 reflectors 7 and several No. 3 reflectors 8 are fixedly installed at equal angles on the outer wall of the mounting bracket 5, and the No. 2 reflectors 7 and No. 3 reflectors 8 are staggered. At the same time, the height of the No. 2 reflector 7 is less than the height of the No. 3 reflector 8, which further enhances the multiple reflection effect of heat radiation. An external thermal insulation layer 9 is provided on the outside of the mounting bracket 5, and the inner wall of the external thermal insulation layer 9 is fixedly connected to the outer wall of the No. 3 reflector 8.

[0026] The built-in thermal insulation layer 2 is made of aerogel felt material. Aerogel is a nanoporous material with extremely low thermal conductivity and good thermal insulation performance. It can effectively block the conduction of heat and effectively block the loss of heat through conduction inside the furnace body, thereby improving the thermal insulation effect of the sintering furnace. The external thermal insulation layer 9 is made of HD-STP thermal insulation material. HD-STP is a highly efficient thermal insulation material with excellent thermal insulation performance.

[0027] Among them, the built-in heat insulation layer 2, the mounting bracket 5 and the external heat insulation layer 9 are all cylindrical structures, and the cylindrical structure optimizes the reflection path of heat radiation and the heat insulation effect.

[0029] Reflector plate No. 1 4, reflector plate No. 2 7 and reflector plate No. 3 8 are all made of aluminum-plated mirror stainless steel, which improves the reflection efficiency of infrared rays and reduces radiation heat loss. In addition, reflector plate No. 1 4, reflector plate No. 2 7 and reflector plate No. 3 8 are all arc-shaped structures, which further optimizes the reflection effect and allows more heat to be absorbed by the sintered material.

[0030] By setting up a No. 1 reflector 4, a No. 2 reflector 7 and a No. 3 reflector 8, the present application can reflect the heat radiation generated in the furnace multiple times, so that more heat is absorbed by the sintered material, while reducing direct radiation loss to the outside world. By setting up a built-in insulation layer 2 and an external insulation layer 9, it can effectively block the loss of heat through conduction, further improving the thermal insulation performance of the furnace body.

[0031] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
