Abstract

A heat shield isolated ultra-high temperature vacuum sintering furnace, comprising a furnace barrel and a heater, a heat shield, a cooling element, and a spacer arranged inside the furnace barrel, and the heater, heat shield, and cooling element are sequentially arranged from the inside to the outside. The spacer is arranged between the outermost heat shield and the cooling part to avoid direct contact between the heat shield and the cooling part. The spacer includes several frames and several first transition links, the frames are elongated ribs, and the several Ribs are erected at intervals on the surface of the outermost heat shield, a number of first transition links pass through the frame and do not contact the heat shield, the first transition links are detachably connected to the heat shield, and the cooling element covers Above several frames, and the cooling element and the frame are detachably connected. In the present invention, the heat shield and the cooling element are isolated by the spacer to avoid direct surface contact between the two, thereby reducing the distance between the heat shield and the cooling element. The direct contact between them plays the role of isolating the fixed connection.

Description

technical field [0001] The invention relates to the technical field of high temperature vacuum sintering furnaces, in particular to a heat shield isolation type ultra-high temperature vacuum sintering furnace. Background technique [0002] In the industry, sintering furnaces are divided into high-temperature vacuum sintering furnaces and ultra-high-temperature vacuum sintering furnaces. Usually, the sintering temperature reaches 1000 °C, which is a high-temperature vacuum sintering furnace, and when it reaches 1900 °C, it is an ultra-high-temperature vacuum sintering furnace. The sintering furnace in this patent It can reach the temperature of 2600 ℃, which belongs to the excellent ultra-high temperature vacuum sintering furnace. [0003] In the existing furnace type, the cooling element is in direct contact with the heat shield, which causes the cooling element to be subjected to high heat transfer by contact and the cooling element to be severely heated.
