Documentation

The documentation of all process-relevant data plays an important role as proof of compliance with heat treatment regulations and for quality assurance. THERMCONCEPT offers a range of options for this purpose.

  • Eurotherm iTools in conjunction with Eurotherm controller Connection to a PC for programming, monitoring and documentation
  • Point and line paperless recorder with up to 6 channels for irretrievable protocols
  • Digital recorders with USB interfaces, Ethernet, memory cards, with up to 18 channels
  • Process standard compliant recorders like e.g. Eurotherm Aerodac 6100A 6180A, 6100XIO, Nanodac

Control and evaluation software

  • Eurotherm iTools for professional process control and documentation of temperature-time profiles and batch data
  • Simultaneous management of several furnaces possible
  • Control of the furnaces from a central PC or via a network
  • Great ease of use

Process norms

This standard covers requirements for temperature measurement in heat treatment plants of the aerospace industry and concerns furnaces and plants as well as their thermocouples, temperature controllers and displays. The documentation of heat treatment processes as well as regular system accuracy tests and temperature uniformity tests play an important role in quality assurance. These are carried out to ensure that components have been heat-treated in accordance with the applicable standards.

The heat treatment plants are grouped into furnace class (temperature distribution in the useful space) and instrumentation version (pyrometry version).

Temperaturverteilung
Furnace class 1 ±3°C
Furnace class 2 ±6°C
Furnace class 3 ±8°C
Furnace class 4 ±10°C
Furnace class 5 ±14°C
Furnace class 6 ±28°C

The CQI-9 is a self-assessment for the heat treatment of components in the automotive industry and was introduced by a working group of leading international automotive manufacturers and suppliers and the International Organization for Standardization (ISO) for continuous improvement, defect prevention and reduction of process deviations.
Relevant contents were taken from the AMS 2750 and adapted to the heat treatments in the automotive industry with regard to application requirements, available furnace technology and test frequencies.
