Low temperature heating chamber with provision for ventilation is termed as “oven”.
Resistance ovens are used for drying and baking potteries, drying varnish coatings, vulcanizing and hardening of synthetic materials and commercial and domestic heating.
The indirect resistance heating chamber for temperature of heat treatment process applied to steel above 700°C except for tempering below that temperature is termed as “resistance furnace“.
The oven is constructed of firebricks or other heat resisting material supported on metal frame work.
The resistance furnace is an enclosure with a refractory lining i.e. a surrounding layer of heat insulation and outer casing of steel plates, bricks or tiles.
The inside proportions of a heating chamber are made to suit the character of the charge and type of furnace or oven.
The nature of material required for the insulation is determined by the maximum temperature of the inner face of the layer of insulation of a heating chamber.
The heating elements are mounted on top, sides or bottom of the oven as the circumstances permit.
An oven may be of “batch” or “continuous” type. In the former the charge is fed intermittently and in the latter the charge travel continuously on a moving platform through the oven. Buy Mccb for furnace
