The invention discloses a vacuum heating furnace which comprises a vacuum heating chamber body and a furnace body arranged in the vacuum heating chamber body. A plurality of heating devices which arearranged around the furnace body and are independent of one another are arranged on the vacuum heating chamber body, and each heating device comprises an electric heating pipe and a fixing rod. One end of each fixing rod is connected with the corresponding electric heating pipe, an external thread is formed in the other end of each fixing rod, through threaded holes are formed in the vacuum heating chamber body, the fixing rods are arranged on the vacuum heating chamber body through the cooperation of the external threads and the threaded holes, and the fixing rods can adjust the distance between the electric heating pipes and the furnace body through threaded structures. A temperature sensor is arranged in the furnace body, the vacuum heating furnace further comprises a temperature controller, and the temperature controller is connected with the temperature sensor and the heating devices. The vacuum heating furnace comprises the temperature sensor, so that the temperature of the interior of the furnace body is guaranteed by controlling the temperature increase and reduction of the electric heating pipes; the multiple heating devices are mutually independent and can be independently replaced; and the distance between the electric heating pipes and the furnace body can be adjusted through the thread structures, and the situation that the furnace body is evenly heated is guaranteed.
Description
technical field [0001] The invention belongs to the technical field of heating furnaces, and in particular relates to a vacuum heating furnace. Background technique [0002] Vacuum heating furnace is a commonly used equipment in the field of physical / chemical reaction engineering. It operates in a vacuum (negative pressure) state and can perform vacuum decomposition of metal compounds at a suitable temperature, such as vacuum decomposition of molybdenite to prepare metal molybdenum powder and sulfur. , Vacuum reduction of metal compounds, etc. can also be carried out. [0003] The main structure of a traditional vacuum heating furnace is a vacuum chamber, a heater and a crucible. When working, the heater and the crucible need to be placed in the same vacuum chamber. The temperature rise of traditional vacuum heating furnace is slow, and the temperature in the vacuum chamber is not easy to control. When one of the electric heating tubes is damaged, the entire heating chambe...
