Pit Type Heat Treatment Furnace

Vertical Pit Type Heat Treatment Furnace

COOLDO Vertical pit type resistance heat treatment furnace is cycle production furnace. We have the RJ seriese and RQ series. The furnace used for heating treatment the metal parts not only can in natural atmosphere but also can in protective atmosphere. and The furnaces are mainly service for bright anealing and tempering various kinds of standard parts , carbon steel, alloy steel parts and magnetic materials, bright anealing of small batch of scrolling strips.

Features

Diameter of Body: 500-4500mm
Temperature: 650 and 950 degree
Melting Method: Gas/fuel/electric.
Chamber: Muffle tank for atmosphere protection

Vertical Pit Type Annealing Furnace Description:

 

pit-type-resistance-heat-treatment-furnaceAlmost 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.

Feature of Vertical Pit Type Resistance Hardening Treatment Furnace:

1), Stronger structure and small temperature difference in working zone,
2), Adopt the energy-saving furnace lining which can make fast temperature rising but saving more than 20% of energy compare with old product.
3),  Large fan installed and multiple heating zone controling for improving the temperature uniformity.
4), The control system can be equipped with normal control instrument or instrument with micro-processor program control according to actual need.
5), The Protective atmosphere can be special fed into the furnace to realize little-oxidizing heating if your need
6), Each product is installed with safety interlock and over-temperature device to provide reliable and safe operation and use.
