Description

Technical Field

[0001] The utility model relates to the technical field of sintering furnaces, in particular to a multi-layer sintering furnace structure. Background Art

[0002] Sintering furnace is a heat treatment equipment that makes the solid particles of ceramic green body bond with each other and metal powder or a mixture of metal powder and non-metallic powder as raw materials at high temperature, and sintered into metal or alloy parts. It is mainly used for pressing and forming iron-based, copper-based and other related powder metallurgy products and ceramics.

[0003] The existing sintering furnace uses several gold heating plates to sinter the internal parts, and the heating effect is poor. During use, the sintered parts and objects are prone to uneven heating, which reduces the working efficiency of the sintering furnace and increases the cost of part sintering. At the same time, the sintering furnace cannot adjust the position of the placement plate according to the size of the part object during use, resulting in the need to replace different sintering furnaces for processing according to the size of the part object.
