MUFFLE FURNACES LKN

Electric furnaces used in the thermal processes of the metallurgical, chemical, dental and ceramic laboratory. The combination of lightened plates, resistances mounted on glow plugs and the use of preformed ceramic fibers, allow these ovens to rise in temperature quickly and cool down just as quickly, so as to offer the greatest advantages in intermittent work. Equipped with a K1P programmer with which it is possible to set 4 cooking cycles each consisting of 8 steps. Models LKN74, LKN75, LKN76, LKN84, LKN85 and LKN86 equipped with wire resistors. LKN77 and LKN87 models equipped with “silicon carbide” elements. Models LKN78, LKN79, LKN80, LKN88, LKN89 and LKN90 with resistors consisting of elements in “silicide molybdenum” Various models available (firing area dimensions and maximum temperature).  

Vernier calipers with micrometric screw for precise measurements. Made of hardened stainless steel.

Vernier 1/50.

Various sizes available.

Electronic centesimal vernier calipers, for precise digital measurements. Made of hardened stainless steel, they have a screen with LCD display.

Equipped with zero button, measurement unit conversion button (mm / inch) and on / off button.

Various sizes available.

The oven consists of a sturdy steel structure which encloses the thermal insulation consisting of bricks low density refractories and preformed fiber sheets highly temperature and shock resistant ceramic thermal.

The oven comprises zones having different characteristics and precisely:

  • smoke entry and evacuation area
  • preheating area
  • cooking zone
  • cooling zone

In all models the heating elements in the cooking zone are in Silicon Carbide allowing these furnaces to be able to operate up to a maximum temperature of 1330 ° C

Optional: Management of the oven using a PC

Various models available (maximum sample size and number of zones).

BULLERS RINGS

Bullers pyrometric rings.

They are the best temperature / time measurement system in all firing processes of ceramic products.

 

PTCR RINGS

The PTCR pyrometric rings have approximately the same characteristics and the same use as the rings

Bullers. They are smaller in size, and their measurement is performed with a digital millesimal micrometer.

 

Instrument for determining depth abrasion resistance of unglazed ceramic tiles. UNI EN ISO 10545-6 norm

For a professional view of the test result, we recommend the combination with the PEIBOX/B cabin.
