High-temperature furnace is a high-temperature pit-type furnace to provide a temperature field for high-temperature melt physical property measurements, the furnace body adopts a double-layer structure, the upper end of the opening, the lower end of the seal. The upper port of the furnace body adopts the flange group, the lower flange is fastened at the mouth of the furnace, welded into a cylindrical structure, with cooling water import and export. The upper flange is opened with hanging wire installation port, electrode installation port, thermocouple installation port, protective gas import and export, etc., connected with the first level of upgrading mechanism, and the furnace mouth is sealed with O-type silicone rubber sealing ring, which is convenient to open.
The software system is self-developed, targeted and stable performance. Temperature control mode adopts visual writing, simple control of temperature rise, constant temperature and temperature fall; lifting mode adopts a combination of automatic, point movement, positioning movement, sensitive response; accurate data acquisition, real-time presentation of temperature-time, density-temperature graphs, with the data of the second fitting processing and other commonly used functions.
It is divided into primary lifting and secondary lifting mechanism, which is controlled by computer software. Through the first lift control high temperature furnace closure, to provide a constant temperature atmosphere for the experiment. Through the secondary lifting mechanism precision control of measuring parts (weight, tungsten electrode, platinum capillary tube) immersed in the crucible melt target position.
