Workspace size	400400600mm(WHD)
Equipment weight	About 5000Kg
Overall dimension	About 3000×2500×2500mm(WHD),Excluding indicator lights, footings, etc
Outline diagram

Rated temperature	1000ºC
Limiting service temperature	1200ºC
Heating element	Molybdenum strip
Heating zone size	680850mm(Diameter depth)
Thermal insulation materials	Molybdenum screen+stainless steel screen
Heating power	50kW
Empty furnace insulation power	≤30kW
Thermocouple	Imported Omega N-type thermocouple
Heating chamber	Adopting a cylindrical furnace body (made of stainless steel SUS304) and a cylindrical heating chamber (made of stainless steel SUS310S and welded with multiple reinforcing ribs to ensure no deformation) structure. The insulation screen adopts a multi-layer molybdenum screen structure, with U-shaped metal support between each layer. The heating element is molybdenum sheet, which evenly surrounds the insulation screen to achieve good temperature uniformity. Featuring long service life, good insulation performance, and minimal vacuum bleeding
Temperature uniformity	≤ ±5ºC
Temperature control stability	±1ºC
Max. heating rate	Rise from room temperature to 1000 ºC≤ 90 min(empty furnace)
Cooling mothed	Cooling with high purity nitrogen in the furnace

Working vacuum	6.7*10-3Pa
Ultimate vacuum	6.7*10-4Pa(Empty, cold, purified)
Vacuum power	Two composite molecular pumps FB-1600 and one rotary vane mechanical pump BSV-90
Vacuum detection	Composite vacuum gauge ZDF5227, measurement range 1.0105~1.010-5Pa
Vacuum unit power	8kW
Vacuum logic	The valves in the entire vacuum system are automatically controlled by programs. In automatic mode, the system automatically operates in sequence and has interlocking and complete safety protection functions. When power is cut off, each valve is in a closed state to protect the process status in the furnace

system composition	Composed of manual ball valve, solenoid valve, vacuum baffle valve, stainless steel pipeline, pressure transmitter, electric contact pressure gauge, float flowmeter, etc
Inflation and deflation logic	When the inflation pressure reaches the set point of the upper pressure limit, it can automatically stop inflating. When the pressure exceeds the set point, it can automatically discharge the pressure, and when it is lower than the set point of the lower pressure limit, it can automatically replenish air. Equipped with a manual system for cooling atmospheric products.

cooling structure	Closed loop water circulation system with branch connected to tap water (emergency use in case of power outage)
Cooling area	Furnace body, furnace door, vacuum unit, and water-cooled electrode

Alarm indication	Audible and visual alarm prompts for water shutdown, overheating, heating overcurrent, mechanical pump, molecular pump failure, etc
System protection	The equipment has functions such as self inspection, fault self-diagnosis, automatic protection, and prevention of misoperation. The vacuum system has corresponding interlocking and interlock protection

Temperature measurement	Measurement using N-type thermocouples
Control instruments	Controlled by an imported intelligent regulator. It has multiple alarm protection functions such as PID parameter Self-tuning, high temperature upper limit alarm, thermocouple failure indication, etc
Heating control	Designed with a PID intelligent temperature control module, it can edit 30 temperature rise curves, store 20 sets of process formulas, and combine PLC to achieve automatic alarm protection functions such as overpressure, overheating, and overcurrent. The 15 inch LCD touch screen display operation has the characteristics of convenient operation, powerful functions, and good stability
control mode	Phase shift control
Overtemperature treatment	When the temperature deviation from the set value exceeds the maximum set deviation value, cut off the heating and give an alarm
