This box type furnace uses domestic high-quality resistance wire as the heating element, adopts a double-layer shell structure and Yudian 30 section programmed temperature control system, and the furnace is made of alumina polycrystalline fiber material The double layer furnace shell is equipped with an air cooling system, which can rapidly raise and lower the temperature, and has the functions of over temperature, coupling breaking, overcurrent protection, etc. The furnace has a temperature field balance It has the advantages of low surface temperature, fast temperature rise and fall, energy saving, etc. It is an ideal product for universities, research institutes, industrial and mining enterprises to do high-temperature sintering, metal annealing, and quality testing.
Muffle Furnace Structure:
Double layers forced air cooling structure,the temperature is less than 60℃.
Integrated compact design,stepped split joint structure,personalized furnace door and touch screen operation more convenient and practical.
Over-temperature protection,over-current overload protection,bias-temperature protection,burnout thermocouple warning,temperature setting ultra-high protection,temperature program ultafast protection.
Safety protection system: the furnace is equipped with a fuse and air switch. When the current exceeds the rated current of the air switch, the air switch will automatically open, effectively protecting the electric furnace.
Materials of furnace chamber:
High quality high-purity alumina polycrystalline fiber solidified furnace formed by vacuum suction filtration.
Made with Japanese technology.
The spacing and pitch of resistance wires in the furnace are all arranged according to Japan's mature thermal technology, and the temperature field is simulated by thermal software
Three side heating (left, right and upper) is adopted to make the temperature field more balanced.
Temperature controlling:
Temperature accuracy: ±1℃ Yudian programmed temperature control instrument (standard configuration)
30 segment program temperature control intelligent PID regulation.
With overtemperature protection and thermocouple breaking protection, the heating circuit of the electric furnace will be cut off automatically in case of overtemperature or thermocouple breaking (when the temperature of the electric furnace exceeds 1200 degrees or the thermocouple is burnt out, the AC relay on the main circuit will be cut off automatically, the main circuit will be cut off, the ON light on the panel will be off, the OFF light will be on, and the electric furnace will be protected limited)
It has power failure protection function, that is, when the furnace is powered on after power failure, the program does not start from the initial temperature, but from the furnace temperature when power failure occurs.
The instrument has the function of temperature self adjustment.
PID automatic control via SCR(silicon controlled rectifier)power control with phase angle fired,current limiting resistor.
