the furnace: double-layer sandwich structure of water, polished stainless steel inner, outer layer of high-quality carbon steel, the upper and lower flange welding into a tube-type structure, opened flat flange seal groove. The use of "O" ring vacuum seal, and set up water cooling device (to prevent overheating "O" ring aging). An observation hole side of the furnace, a thermocouple hole, thermocouple selection of W-Re type, both high-temperature heating zone automatically exit the function. 1600 ℃ the following tungsten rhenium thermocouples, 1600 ℃ above instrument used by the U.S. two-color infrared thermometer.
the lid: the use of double-laminated head structure, and with water cooling. .
bottom and lifting mechanism: the use of furnace bottom and the "O" ring vacuum seal, and set up water cooling, place the crucible on the bottom or processed material, bottom of the opening and closing pneumatic lift for easy access to materials, connection with the furnace lid fastening clamp mounted seal are used.
oven racks: the welding of steel and steel plate into a box structure, placed in the box on the furnace.
the vacuum system: one set 2X-15 by a mechanical pump with solenoid control valve (to prevent a sudden power failure due to mechanical pump oil intrusion), manual valve, vacuum gauge (± Pa), gas valve, release valve, charging protective gas (Ar, N2) slightly positive pressure (<0.05Mpa) pump connected with the vacuum pipe, corrugated metal hose quick connector coupling (slow shock), vacuum measurement by the thermocouple vacuum gauge digital implementation.
the control system: the use of thyristor voltage regulator control, the program used by the U.S. Honeywell digital display temperature control with PID regulator, over-temperature alarm sound and light, the main electrical components used Omron and Schneider brand, electric control panel box according to Siemens standard production, precise temperature control, easy to operate.
the cooling system: from a variety of pipeline valves and other related devices, has a sound and light alarm without water automatic power off function.
heating elements, heat shield: the use of high-purity graphite processed into cylindrical structures, heat shield using graphite carbon felt, uniform heating, radiating, heat shock, and can be rapid heating and cooling. External stainless steel frame support, fixed.
inflatable systems: the meter, fine-tuning valves, intake manifolds and other components.
transformer and connection cable: The match with the use of power transformers and cables.
