Product Description

Although there are many kinds of furnace on the market, such as  melting furnace, propane furnace , induction furnace and muffle furnace. Did you know how much does a furnace cost and what furnace parts are. Here we would like to share a new box type furnace . SA2 series box-type atmosphere furnace is a self-researched product by our company, it’s a smart, high efficient, energy saving, environmental protection precision high temperature electric furnace . Comparing to box-type furnace, atmosphere furnace has product advantages of vacuum pump ing and gas inflation, and atmosphere furnace owns advanced structure, elegant and beauty in appearance, shell is made from excellent cold-roll steel sheets, been processed by advanced numerically controlled machine tool and import epoxy powder electrostatic spray technology, anti high temperature, anti corrosion and maintain no color fading for a long time. SA2 box-type atmosphere furnace is discontinuous running, adopts double-layer shell structure and (adjustable in 30-50℃range) program temperature control system, phase shifting trigger, silicon controlled, hearth is made form most advanced aluminum oxide ceramics material, double-layer furnace mantle room is equipped with air cooling system to rise or cool the temperature rapidly, furnace body uses step type assembly structure, furnace door and door frame is an integrated design, which efficiently prevent hearth top from collapsing, close fit of furnace door and door frame makes thermal energy difficult to lose, lengthen the service life of furnace door. SA2 box-type atmosphere furnace is applicable for universities and colleges, scientific research institutions, atmosphere protection sintering of mining industries, it’s an ideal equipment for atmosphere reduction, with features of uniform temperature, fast temperature rising or falling speed, energy saving, applicable for various gases, vacuum pumping, etc.

Box-type atmosphere furnace, box-type furnace and tube-type furnace are called muffle, they are a kind of universal heating device which different in shapes. SA2 box-type 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 SA2 box-type atmosphere furnace:

  1. Lanphan box-type atmosphere 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. Box-type atmosphere 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. Box-type atmosphere furnace is separate from control part, in this way, electronic temperature controller can accurately control temperature even under long time running.
  5. Box-type atmosphere 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.
