Chamber-type furnaces - Type PKM 6.12.5
Chamber furnaces are the most universal for such heat-treatment processes as quenching and forging. Due to the wide range of products, furnaces with various diameter working chambers are used both in machine tool production and at the heat-treating departments for basic products of our customers. More than 2 000 furnaces of this type are operated at present and the corresponding reference list includes more than 1 500 customers.
Chamber-type furnaces - Type NKO 10.20.10
Technological processes related to tempering and stress relief after welding require high-precision temperature control and uniform temperature distribution in the working chamber. For the processes involving heat treatment of large-sized heavy charges we offer the NKO chamber furnaces.
Design features:
Design features:
- Max temperature up to 700°C.
- Forced atmosphere circulation system (fans, screens, diffusers).
- Three-side heating: air passes at a high speed from sidewalls heaters located behind the screens and completes the circuit flowing through the charge which is heated by the hearth heaters from below.
- Uniformity within ±5°C.
- roof and door are lined with cost-saving Unifrax fiber insulation and walls have fiber or multilayer lining.
- Power consumption is 30-50% less as compared to brick linings.
- M and MDO embodiment furnaces are equipped with a motorized hearth allowing to charge up to 30 tons into the large-sized furnaces.
- Multizone temperature control system.
- Emergency shutdown at temperature rise over 750°C.
- Cast heat-resistant hearth plates and carborundum floor plates protecting the hearth against mechanical shocks.
- Furnace accessories (baskets, shelves and stands)
- Forced charge cooling system.
- Removal system for products of combustion (oils, emulsions).
- Computer-aided data collection and storage system (documented technological parameters).
- Frequency-controlled hearth drive (acceleration – deceleration) for large charges (more than 7 tons).
- Motorized door lifting drive.
