Product Description
1. Heat Treatment chamber:
- Max. operating temperature: 550 °C,
- Heating with natural gas (Option: Electrical heating),
- In case of natural gas heating: chimney and dust filter included,
- Calculation for the energy consumption (unit kWh) is part of the quotation,
- Indirect heating - use muffle furnace concept,
- Description of insulation material incl. MSDS necessary,
- Max. outside temperature = ambient temperature + 45 °C,
- Consider lock units on the ENTRY and EXIT side to reduce the energy loss keep the temperature inside the furnace stable,
- Consider the homogeneous temperature within the complete interior space of the furnace, ventilation preferred. Avoid hot spots,
- Consider the layout in segments, for potential future capacity extension,
- Robust and low-maintenance drive units (description in quotation is necessary),
- Outside construction: Carbon steel,
- Inside construction: Stainless steel DIN EN 1.4301/1.4016 or ASTM 304/430, continuously seam welded,
2. Cooling zone:
- cooling zone included in the safety area,
- cooling supported by air fan ventilation,
- when the parts come out of the cooling zone, the product's temperature should be approx. 50 °C to 60 °C so that they can be handled by workers with gloves.
3. Process Control
- Process flow inside the safety area fully automated following operator program, incl. temperature control and permanent temperature measurement and documentation on data carrier,
- Data carrier HDD, USB output (to be locked by BIOS),
- Connection to the GFSZ server (details to be developed),
- Documentation of heat treatment batches with time stamp,
- Alarm messages on operator panel in case of deviation of process parameters incl. blocking of the potentially affected parts in the server,
- Dimensional check by gauge (provided by GF Suzhou),
- Check of mechanical properties (duty of GF Suzhou),
