Abstract

The invention discloses a vacuum sintering furnace achieving four-area temperature control. The vacuum sintering furnace comprises a sealing box, a heating device and a heat insulating layer; the heating device is arranged between the heat insulating layer and the sealing box; the heating device comprises two heating body units, and the heating body units surround the front portion and the rear portion of the side face of the sealing box in the axis direction respectively; the heating body units are of the same structure, and each heating body unit comprises a heating rod, an electrode rod anda connecting sheet, is connected with two three-phase transformers and is used for heating an area to be heated of the sealing box corresponding to each heating body unit. By means of the vacuum sintering furnace, the heating uniformity of the whole heating device can be improved, then the deviation of temperatures in all areas in the furnace is reduced, and the cost for balancing the temperatureuniformity in the furnace is lowered.

Description

technical field [0001] The invention relates to the field of heating temperature control, in particular to a vacuum sintering furnace realizing four-zone temperature control. Background technique [0002] In order to increase the production capacity of the vacuum sintering furnace, it is necessary to increase the space in the furnace, but the increase in the space in the furnace will cause a large difference in the temperature in different areas of the furnace, usually >±10°C, and with the increase of the space in the furnace , During the heating process of different regions, due to heat capacity, heating, heat preservation and other factors, the temperature difference in different regions will be larger, usually >±20°C. On the other hand, since the heat conduction of the heating element of the vacuum furnace is mainly in the form of radiation, but due to the different radiation heat conduction efficiency at different temperatures (intensity of light), the difference i...
