Product Features
- Vertical Structure, Suitable for Heat Treatment of Long Workpieces
The furnace body adopts a vertical structure, with workpieces vertically loaded into the furnace tubes from the top. This is particularly suitable for the heat treatment of long, high aspect ratio workpieces (such as long bars, long tubes, and long shafts). Vertical placement effectively prevents workpieces from bending and deforming under their own weight at high temperatures.
- Open Furnace Chamber Design
The furnace chamber adopts an open structure, allowing for easy replacement of furnace tubes or cleaning and maintenance. Users can flexibly choose between stainless steel tubes, quartz glass tubes, and corundum tubes according to process requirements, without the need for a complete equipment replacement.
- Uniform Heating Field Around the Furnace Tubes
Heating elements (silicon carbide rods) are installed around the furnace tubes, arranged horizontally with the tubes. The temperature uniformity within the furnace is ±1℃, and the temperature control accuracy is ±1℃. The maximum operating temperature is 1250℃, and the long-term operating temperature is 1200℃.
- Equipped Gas Control Cabinet
Equipped with an independent gas control cabinet, offering two types of gas (selectable from 1 to 10 types). Imported stainless steel valves, two flow meters (0-300 ml/min, optional mass flow meter, float flow meter, etc.). Gas mixing ratio is achieved by adjusting the values of each inlet flow meter. Equipped with a dual-indicator pressure gauge for both positive and negative pressure.
- Pressure Protection + Gas Leak Alarm
The pressure protection system receives signals from an electrical contact pressure gauge or pressure sensor, driving the control module to close the electromagnetic inlet valve and activate the electromagnetic exhaust valve and alarm. The gas leak alarm device automatically shuts off the electric heater and gas supply and activates the exhaust system when it detects excessive levels of toxic or hazardous gases in the indoor air.
