The invention discloses a vacuum extrusion device for preparing titanium and titanium alloy, relates to the technical field of titanium and titanium alloy preparation, and aims at solving the problems that an existing device is prone to sealing failure, not thorough in cleaning and low in temperature control precision. The device comprises a vacuum chamber, an extrusion rod, an air passage system, an air source distributor, a temperature monitoring module and an external control module. The working section of the extrusion rod is provided with three sections of spiral grooves, and precise coupling of dynamic sealing, self-cleaning and temperature field regulation and control is achieved through cooperation of an air channel system and multiple air channels. The first section of main sealing spiral groove forms a high-pressure air curtain, the second section of temperature control spiral groove adjusts the temperature in a self-adaptive mode through a shape memory alloy ring, and the third section of cleaning spiral groove conducts deep cleaning through the reverse suction effect. And the external control module adaptively regulates and controls each gas path according to temperature and impurity concentration monitoring data, so that the structure is simplified, the efficiency is improved, the product quality stability is guaranteed, and the batch production requirements of high-quality titanium and titanium alloy are met.

The utility model relates to resistance furnace technical field provides a resistance furnace with good heat preservation effect, including resistance furnace shell, resistance furnace shell front end fixedly connected with front seal board, resistance furnace shell is fixed in the heat -insulating layer of heat preservation, the heat -insulating layer both ends side wall all install a plurality of resistance sheet, the ceramic rotation disc of rotation disc bottom -end middle part rotatory connection has, rotation disc lower fixedly connected with connecting shaft, the heat -insulating layer with resistance furnace shell between be provided with drive mechanism, drive mechanism with connecting shaft transmission connection. The utility model discloses, can pass through the rotation of rotation disc, makes the material multi -surface even heating, improves the heating evenness, avoided the product quality defect because of the uneven heating.
