INDUSTRIAL OVENS FOR THE FIRING PROCESS FOR THE PRODUCTION OF COMPOSITE MATERIALS – AMARC srl

INDUSTRIAL OVENS FOR THE FIRING PROCESS FOR THE PRODUCTION OF COMPOSITE MATERIALS

The customer produces composite material for the renewable energy sector, and needed to start up a new production from scratch.

The amarc team designed and produced a battery of 10+5 ovens as described above.

The project was important because of the number of units produced, but it was also a challenge (that we won) especially to satisfy the qualitative requirements of the process: required temperature tolerance (and reached) +/-1°c.

AMARC handled the entire process from design to installation, start up and training of operators.

AMARC technicians also assisted the customer in the subsequent activities involved in the preventive maintenance and calibration of the temperatures to maintain the peformance of the process over time.

Technical data

Thermoregulation areas: 1
Working dimensions WxDxH in mm: 10 ovens 2000x6500x2100
5 ovens 2000x1300x1700
Installation site : Indoor
Heating power supply: Electric
Nominal operating temperature: Up to +80°C
Temperature accuracy: +/- 1°C
Doors: 1 double leaf door for both types
Base: Both types of ovens are constructed without floors
Finish: Stainless steel interior, exterior carbon steel painted in RAL 7035 with standard cycle
Control panel (Process + Logic): Built in control panel and wiring ducts. Heating process control in PID mode.
For the 10 large ovens a 48x48 mm pogrammer processor was installed for standard temperature for cycles control.
For the 5 small ovens, 3.5" touch screen recorder programmer was installed for control of the work cycles and temperature recordings.
Data Recording: A significant part of the design involved the recording of temperatures. To ensure the quality of their process, the customer requires a report showing, for every batch loaded, that the temperatura tolerances are maintained along the work cycle (+/-1°c compared to the set point). To achieve this result:
  • 2 temperature probes were installed in addition to the process probe

  • a system was installed for the supervision and recording of temperatures by the aforementioned temperature probes.
For the 5 small ovens a touch screen recorder was provided on board the machine. However, for the 10 large ovens, a control and recording panel was provided for all 10 ovens. A blank plc collects the temperatures of the ovens and sends these to a pc for reading and download.
