Laboratory Furnace upto 1800°C with MoSi2 Heating Element

GENERAL FEATURES & DESCRIPTION :

  • High Quality MoSi2 1800 or 1900 grade Heating Elements Vertically suspended directly radiating on both sides of the heating cavity to derive symmetrical heat distribution.
  • Hot-face Super Refractory Mullite / Bubble Alumina insulation backed by low heat capacity refractory and Fibrous insulations of different grades
  • Dual Shell with Fan cooling to ensure low Skin temperature.
  • Insert type Swing aside Parallel – moving Door (Chain guided) with Peep Hole facing away from the Operator in any position.
  • Fiber wool sealing in the Door for least Heat leakage
  • Thyristorised Circuitry with adjustable Current limit and Soft-Start features for maximum protection to Heating Elements and for simple control of heat-up rate.
  • Air Cooled Step Down Transformer/s having minimum 3 Nos. Input Step Change facility for desired Secondary Voltage
  • Micro-processor based Digital PID Temperature Controller / Programmer with Pt/Rh Thermocouple (Type ‘B’ or ‘LJ’) in pure Alumina Sheath.
  • Digital Over-Temperature Protector with ensure overall safety.
  • Exhaust air outlet at Roof of the Furnace
  • PC Interface for On –line Date Acquisition / Storage Graph / Table also available (Optional)

PERFORMANCE :

  • Temperature Control Accuracy within ±1°C of set point.
  • Temperature uniformity within ± 5°C near T'max with soaking.
  • Carefully Engineered for rugged use and easy maintenance.
  • Easy Installation and Hassle Free Operation

APPLICATIONS :

  • Trial firing and P.L.C.A.R. Testing
  • Industrial R & D work
  • Thermal testing in Quality Control Laboratories
  • Precision firing of Oxide & Electronic Ceramics and high temperature products.
  • Sintering and Processing in Powder Metallurgy

CONSTRUSTION :

  • Welded angle-iron frame floor model construction in two sections with Hammer-Tone painted Sheet-metal Paneling.
  • Top section comprises the Heating Cavity assembly
  • Base frame houses the specially designed Transformer/s complex with Electrical gearing (Analog Voltmeter, Ammeter Switches etc.) thereby needing lesser floor area
  • Heat-affectable metallic parts in the vicinity of Door opening are of heat-resisting
  • Stainless-Steel fabrication.
