Electric Muffle Furnace

Electric Muffle Furnace

The general design and construction comprises of an Outer chamber fabricated out of thick cold rolled mild steel sheets, Rectangular in shape placed horizontally with opening in the front. Refractory Muffle of required size forms the inner chamber. This is surrounded by ceramic fibre blankets on all the four sides and the rear to reduce heat losses to a minimum.

The chamber is provided with a single door with 100mm thick ceramic fibre insulation mounted on heavy duty hinges and provided with latch. The furnace is heated by Kanthal A1 heating coils wound in spiral form on the muffle embedded in high grade refractory cement and backed by ceramic fibre blankets.

The temperature inside is maintained at any desired level within the operating range by a Digital Automatic Temperature Indicator-cum- controller working in conjunction with a Cr/Al thermocouple housed in the hot zone.
