Product Description

There are different types of furnaces, such as open hearth furnace, aluminum melting furnace , gas furnace , and oil furnace etc.. SK2 tube furnace is a high performance high energy-saving new type furnace who adopts international advanced technology, there are various tube furnace types: single-tube, double-tube, horizontal type, open-type, vertical type, single warm area, double warm area, triple warm area, etc. SK2 tube furnace is applicable for universities and colleges, scientific research institutions, industrial and mining enterprises. With advantages of safe, operation easily, high temperature control accuracy, good heat preservation effect, large temperature range, various warm area, uniform temperature, can match to atmosphere furnace and vacuum pump ing type furnace.

Tube furnace, box-type atmosphere furnace and box-type furnace are called muffle, they are a kind of universal heating device which different in shapes. SK2 tube furnace’s working principle is on basis of conservation of energy, that is transfer electric energy to heat energy. When furnace is in normal working condition, apply voltage and current on heating element(resistance), heating element produces a large amount of heat in working room, and generates heat convection and heat radiation, thermal insulation material absorb and emit a few heat and isolate most heat to make working room temperature rise gradually, finally reach to pre-set temperature. When reach to certain temperature, thermocouple senses working room temperature and feedback to temperature control meter(PID control), then control voltage, current in order to control the thermal power of furnace, and reach pre-set program temperature.

Product features of Lanphan SK2 tube furnace:

  1. Lanphan tube furnace has a widely application range, can be used for gravimetric analysis, ash content measurement of organic matter and coal.
  2. Heating device is built in both sides of hearth inwall, which can quicken temperature rising and make material uniformly heated.
  3. Tube furnace’s heating element is made from special fireproofing material, and it totally hides in inwall, avoid corrosive gas and steam, thus lengthen service life.
  4. Tube furnace is separate from control part, in this way, electronic temperature controller can accurately control temperature even under long time running.
  5. Tube furnace’s shell has double layers, its bottom is equipped with a refrigeration fan, the air circulating can keep low temperature of the surface, you have no worry for scalding.
  6. Digital setting and display panel points to accurate temperature.
  7. Temperature control range from 30℃ to 50℃, accuracy is ±1℃.
  8. Heating rate is 0-40℃/min(advise =<20℃).
  9. Hearth is made from aluminum oxide ceramics.
  10. Vacuum pumping is applicable inside the hearth, vacuum degree≥-0.1Mpa.
  11. Under one established temperature, inflate certain man-made atmosphere into furnace, in order to achieve the purpose of heating treatment, such as gas carburizing, carbonitriding, bright quenching, anneal, normalizing and so on.
