Supervisory control of an automatic installation for heat treating
The system manages a continuous line for carburizing, tempering,
hardening heat treatments.
The SCADA application communicates with a PLC Siemens SIMATIC S7
network using MPI protocol (server Applicom).
Batch materials are linked to their treatment recipes and positioned
on parking platforms. An asynchronous process logic verifies furnaces
and washers availability to receive the materials.
The system allows accessing the recipes database that contains batch
identification and process data. The main template shows position
and progress status of each process and provides a detailed view of
each heat treatment element. At the end of any batch production,
the application generates quality control reports containing batch
identification data and temperature and carbon percentage charts for
each phase of the treatment; in each report it is available a section
in which it is possible to insert the measure of mechanical
characteristics of produced material.
Optionally, Sielco Sistemi offers a scheduling and optimizing batch
system that allows sending of many consecutive recipes to the
treatment line and obtaining the best sequence to use all the heat
treatment elements in a rational and economic way.
