Introduction of vacuum tube furnace:
GSL-1700X series High Vacuum Tube Furnace uses silicon molybdenum rods as heating elements, with a rated temperature of 1600℃. It uses B-type double platinum rhodium thermocouples for temperature measurement and 518P temperature controller for automatic temperature control, so the High Vacuum Tube Furnace has a high temperature control accuracy (±1℃). In addition, the High Vacuum Tube Furnace has a vacuum device and can work in a variety of atmospheres, which greatly improves its scope of use. High Vacuum Tube Furnace has the advantages of high operating temperature, high-precision temperature control, simple operation and convenient maintenance. This High Vacuum Tube Furnace can be widely used in metallurgy, machinery, light industry, commodity inspection, colleges and universities and scientific research departments.
Main features of Tube furnace:
1. Tube furnace chamber size: 290mm*220mm*160mm;
2. The maximum temperature of Tube furnace can reach 1700℃ (≤0.5h);
3. Tube furnace can realize multi-stage temperature control program and precise temperature control.
Precautions of High Vacuum Tube Furnace:
The gas pressure in the furnace tube of High Vacuum Tube Furnace cannot be higher than 0.02MPa.
Due to the high gas pressure inside the gas cylinder, a pressure reducing valve must be installed on the gas cylinder when the gas is introduced into the furnace tube. It is recommended to purchase a pressure reducing valve from our company. The range of our pressure reducing valve is 0.01MPa-0.1MPa, which will be more accurate and safe when used.
For the experiment of sample heating, it is not recommended to close the exhaust valve and the air inlet valve at the flange end of the furnace tube. If you need to close the gas valve to heat the sample, you need to pay attention to the indication of the pressure gauge at all times. If the pressure indication is greater than 0.02MPa, you must immediately open the air relief valve to prevent accidents (such as furnace tube rupture, flange flying out, etc.).
The gas flow rate should be limited to <200 SCCM (or 200ml/min).
Technical parameters of High Vacuum Tube Furnace:
| Product name | 1700℃ High Vacuum Tube Furnace (290mm Heating Zone, with 60 or 80mm OD Corundum Tube and Flange) - GSL-1700X |
| Main parameters | Rated Power: 5.5KW Rated Voltage: AC220V 50/60HZ Rated Operating Temperature: 1650℃ Max Operating Temperature: 1700℃ (≤0.5h) Recommended Heating Rate: Below 1400℃: ≤10℃/min; 1400℃ to 1600℃: ≤5℃/min; After 1600℃: ≤2℃/min. Heating Element: Silicon Molybdenum Rod Thermocouple: Type B Heating Zone Length: 290mm |
| Furnace structure | The inner furnace surface is coated with 1750-degree high-temperature aluminum oxide coating imported from the United States, which can improve the reflectivity and heating efficiency of the equipment, and also extend the service life of the instrument. It adopts a double-layer shell structure, and the double-layer furnace shell is equipped with an air-cooling circulation system. The furnace uses high-purity polycrystalline alumina fiber to greatly reduce energy loss. |
| Furnace tube and flange | · A corundum tube is standard, size: Φ60*1000mm. Corundum tubes of different diameters of Φ80, Φ100, and Φ120 are optional · Two stainless steel vacuum flanges are standard (mechanical pressure gauges and stainless steel stop valves are installed on them) · A 4-hole ceramic tube is installed on the inlet flange, which allows the intake air to pass through the pipe plug and directly enter the high-temperature zone. The two matching pipe plugs are directly fixed on the flange, which is convenient for customers to install and remove each time · A KF25 interface is installed on the vacuum end flange, which is convenient for customers to connect the vacuum pump. A set of flange support frames is installed on the furnace body for customers to place the flange after each disassembly and installation of the flange. |
| Vacuum system (optional) | · Vacuum degree: 50mTorr (using mechanical pump) · Mechanical pressure gauge measurement range: -0.1-0.15Mpa · Pressure limit in the furnace tube: ≤0.02Mpa · Various vacuum pumps can be selected in our company |
| Temperature control system | ·Includes a YD858P temperature controller; ·PID automatic temperature control system; ·Intelligent 50-segment programmable control; ·Built-in overheat protection and thermocouple fault alarm; ·Temperature control accuracy: ±1℃; ·Default DB9 PC communication connection port; ·Passed MET certification; ·Optional computer temperature control software (for YD858P series controller) is used to control the heating curve and export data; |
| Tips | ·In order to ensure the uniformity of the temperature field and the sealing of the flange, the instrument needs to be plugged with alumina tube plugs at both ends of the furnace tube before heating to prevent heat loss; ·When cooling, please use the program to cool down and set the cooling program. It is not recommended to directly "Stop" to cool down; · Please do not turn off the power of the equipment when the temperature is above 500℃ to prevent safety problems; |
