• Hot air furnace is made of high temperature resistant corundum tube, inner diameter 100±5mm, length 240mm, by 1.3±0.1mm metal alloy electric heating wire, through the voltage regulator control PID regulation mode can provide more than 750℃ heat source, temperature control accuracy ±1℃

  
  

• Inner tube furnace diameter 75mm, 240mm high, made of copper material, heat resistance is greater than 750℃

  
  

• Imported high temperature thermocouple measuring furnace body and furnace temperature, temperature measurement accuracy ±0.1℃

  
  

• The air source is filtered through the top of the furnace tube and the inner tube, and enters the inner tube from the bottom after heating and circulation between the two tubes

  
  

• The air source is adjusted by the imported precise rotor flowmeter, and the inlet pressure is regulated and controlled by the brand pressure gauge and regulating valve to provide a stable air source

  
  

• Stainless steel furnace shell, and furnace tube filled with heat insulation material, to avoid the shell temperature too high.

  
  

• The sample tray has a diameter of 40mm and a depth of 15mm. It is made of high temperature resistant stainless steel. It is connected with the gripper through the stainless steel transmission bar.

  
  

• The igniter consists of copper tubes with an inner diameter of 2.0mm, and the flame size is adjusted to 20mm±2mm by a precision rotormeter

  
  

• High pressure pulse automatic ignition, ignition stability and reliability, high security

  
  

• The fire source device can be adjusted horizontally and 45 degrees to avoid the interference of the refractory partition on the top of the furnace when the sample is taken out

  
  

• The self-designed standard electrical cabinet is equipped with Siemens PLC system to achieve functional control. The upper computer software is designed based on NI Labview, with guiding operation, which can record real-time test data, display, save and report output.

  
  

• The top of the test furnace is equipped with CCD image shooting system, which can be used for real-time monitoring of sample flashover time

  
  

• The program can automatically generate experimental report and output.
