Audited Supplier | Typical application fields | The equipment is mainly used for high vacuum heat treatment of metal materials or vacuum brazing of stainless steel, titanium, titanium alloys, and high-temperature alloy parts |
| Furnace structure | Horizontal, single chamber, furnace body and door adopt double layer water cooling, front door structure. It's composed of furnace body, heating chamber, vacuum system, inflation system, water cooling system, electric control and power supply system, etc |
| Workspace size | 400*400*600mm(W*H*D) |
| Equipment weight | About 5000Kg |
| Overall dimension | About 3000×2500×2500mm(W*H*D),Excluding indicator lights, footings, etc |
| Outline diagram |  |
| Rated temperature | 1000ºC |
| Limiting service temperature | 1200ºC |
| Heating element | Molybdenum strip |
| Heating zone size | 680*850mm(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 1.0*105~1.0*10-5Pa |
| 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 |
