Vacuum sintering furnace

Abstract

The invention relates to the technical field of ceramic vacuum sintering furnace. A vacuum sintering furnace comprises a rack, an upper part pressing device, a furnace body, a lower part supporting device, a vacuum device, a hydraulic device, a water cooling device; the upper part pressing device, the furnace body and the lower part supporting device are arranged at the front part of the rack; theupper part pressing device is arranged at the top of the furnace body, and the upper part pressing device penetrates through the top of the furnace body and used for pressing materials; the lower part supporting device is arranged in the bottom of the furnace body, and the lower supporting device penetrates through the bottom of the furnace body for supporting materials and is matched with the upper part pressing device; the vacuum device is arranged at the rear part of the rack, and the vacuum device is communicated with the furnace body; the hydraulic device and the water cooling device arerespectively arranged at the lower side of the rear of the rack; and the hydraulic device is used for performing hydraulic control, and the water cooling device for cooling control. This patent has the advantage of improving the ceramic material in the sintering process, improve the stability of the vacuum pumping effect to prevent the occurrence of accidental explosion, temperature control effect is improved, and the sintering efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of ceramic vacuum sintering furnaces. Background technique [0002] Vacuum sintering furnaces are widely used for sintering ceramic powders, ceramic ferrules and other zirconia ceramics. Existing sintering furnace structure, such as a magnetic steel vacuum tube type sintering furnace disclosed in the Chinese utility model patent whose publication number is CN202955965U and whose announcement date is 2013.05. The cavity of the sintering material has a heating mechanism in the sintering furnace tube. The heating mechanism sinters the material in the cavity. The sintering furnace tube is connected with an air extraction system. and the exhaust system are connected to the control box, and the control box regulates the heating and vacuuming process; the sintering furnace is connected with a feeding pipe at the entrance of the sintering furnace tube, and the material is transported into the sintering furnace tube...
