bell type annealing furnace

bell type annealing furnace

This type furnace. mainly be used for metal parts in natural atmosphere or protective atmosphere for heat treatment.

Applicable for bright anealing tempering of carbon steel, alloy steel parts and magnetic materials in protective atmosphere, and for bright anealing of small batch of scrolling strips

Parts Description:

1), Shell:made by steel plate and structural steel.
2), Inside of furnace cover: made by stainless steel plate.
3), Burner liner: using the super light and energy conservation micropore fire-resistant heat reserving brick
4), Aluminum silicate fiber at between burner liner and shell, and also fill full of thermo-insulating power in gap.
5), Resistance wire: use the 0Cr25Al5 high resistor alloy wire installed upon brick.
6), Furnace cover: use the manual lever lifter or motor-driven or hydraulic.

7), We have installed fan which made by a heat-resistance stainless steel shaft and fan blade for uniform heating the work-piece
8), Limit switch installed near the lifter device for safety operation.

Characteristic :

1)Rational structure, uniform furnace temperature, small upper & lower temperature difference in working zone, especially applicable for heating and heat treatment for long axial work-piece.

2) Adopt energy-saving furnace lining, fast temperature rise, low empty furnace consumption, save more than 20% of energy compare with old product.

3)The control system can be equipped with normal control instrument or instrument with micro-processor program control according to actual need.

4)When needed during process, protective atmosphere can be fed into the furnace to realize little-oxidizing heating.

5)Each product is installed with safety interlock and over-temperature device to provide reliable and safe operation and use.
