Pit type annealing electric resistance furnace heat treatment furnace for iron core wire

   The pit type furnace is cycle production furnace. Mainly used for metal parts in natural atmosphere or protective atmosphere for heat treatment. Applicable for bright annealing tempering of carbon steel, alloy steel parts and magnetic materials in protective atmosphere, and for bright annealing of small batch of scrolling strips.

    Structure Almost pit type furnace are round type and installed in the pit for easy loading and un-loading the goods, which consist of furnace body, cover, heating element, loading basket, and temperature control system.
    Parts Description: 1) Body Shell: Made by steel plate and structural steel. 2) Inside of furnace cover: made by stainless steel plate. 3) Burner liner: Adopt 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: Adopt the 0Cr25Al5 high resistor alloy wire installed upon brick. 6) Furnace cover: Adopt the manual lever lifter or motor-driven or hydraulic. 7) Furnace installed fan: Made by a heat-resistance stainless steel shaft and fan blade for uniform heating the work-piece 8) Limit switch: Installed near the furnace cover for safety operation.   
    Controlling of the furnace temperature, automatic recording, over temperature automatic power-off protection and so on.

Products On Site:

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.

Furnace and temperature control cabinet generally choose the standard fumigation-free wood packing boxes for packaging.Other accessories, according to the specific items to choose the appropriate packaging.
