The invention discloses a high-temperature sintering furnace with controllable gas pressure and temperature. The high-temperature sintering furnace with controllable gas pressure and temperature is applicable to materials needing to be tested in high-temperature sintering. According to the high-temperature sintering furnace, a cavity which enables gas, temperature and gas flow to be uniform and stable is formed by a lower multi-hole plate (10) and an upper multi-hole plate (11), and can avoid turbulent flow, and the multi-hole plates are installed on the lower portion of a furnace chamber (6); a heating system is formed by an spiral electric stove wire (5) and a spiral electric stove wire (8) installed at the bottom of the furnace chamber (6), and the spiral electric stove wire (5) is arranged on the inner wall of a furnace body (7) and is twined from bottom to top; an upper thermocouple (13) and a lower thermocouple (12) are externally connected with a temperature control component so that the temperature in the furnace chamber (6) can be adjusted; furnace lid air holes (4), a gas collecting cavity (2) and a gas outlet (1) in a furnace lid (3) can exhaust inside-furnace exhaust gas in the gas collecting cavity (2) in time under the pressure difference formed by an externally connected vacuum pump. The high-temperature sintering furnace with controllable gas pressure and temperature is simple and reasonable in design, the temperature in the furnace is controllable, the problems that the temperature difference in a furnace is large or turbulent flow appears are solved, and the stability of the experimental result of material sintering and the reliability of data are obviously improved.
Description
Technical field [0001] The invention belongs to the technical field of equipment for high-temperature sintering, and mainly relates to a high-temperature sintering furnace with controllable air pressure and temperature. Background technique [0002] Modern scientific research and production technology fields continuously improve the performance requirements of materials. The experimental results of materials are an important basis for product selection. For example, some materials such as powder metallurgy and ceramic materials need to be sintered under high temperature conditions. Since the results of the sintering experiment are closely related to the performance of the material products, stricter requirements are put forward for the sintering environmental conditions of the high-temperature sintering furnace used for the sintering experiment, such as the temperature difference in the furnace and the emission of harmful gases. Affect experimental results. However, most of t...
