Everything under control:The SyncroTherm Control concept
The SyncroTherm vacuum heat treating system is equipped
with an easy-to-operate system to control, monitor and docu-
ment all processes.
SyncroThermControl
This data base hosted by a PC system
supports the following functions:
system control
operating modes
recipe creation and management
data back-up
load record generation
alarm management
touch-PC-solutions, integrated in
switch cabinet
optional: redundant PC solutions
connection to several recipe clients
Plant control
A Siemens PLC manages all activities
within the SyncroTherm system including
temperature, pressure and gas ow. The
system is operated via touch panel which
communicates with a host computer,
installed in the switch cabinet. The host
computer manages all documentation
and secures the traceability of individual
processes.
he One-Piece-Flow
rinciple
th the one-piece-ow principle, the heat
atment of large batches is converted to
atment of single components. The parts
e charged in one layer on one workpiece
rrier. The at-panel heating elements
talled in top and bottom of each hot
ne radiate the heat directly onto each
rt, heating these 2D-charges rapidly
d homogeneously. Using micro-alloyed
eel, parts are processed at high temper-
ures (above 1000C / 1832F) without
desired grain growth. Further, the
gle-layer charge provides the possibility
control high pressure gas quenching
ich is customized for various parts,
apes and dimensions.
echnology
e SyncroTherm system consists of a
essure-tight chamber in the front which
rves primarily as quench chamber as
ell as loading chamber. The treatment
amber located behind this chamber
mprises a cold loading area with a
escoping loader and up to six hot zones
ich are arranged one upon the other.
ch hot zone may hold one workpiece
rrier. The treatment chamber always
mains under vacuum and is separated
m the quench/loading chamber by a
essure-tight door.
The Process
An external handling system places single
parts on the workpiece carrier and trans-
ports it through the front opening in the
quench chamber, which initially serves as
a loading chamber. The chamber is evacu-
ated of all unwanted oxygen. The tele-
scoping loader, integrated in the treatment
chamber, places the workpiece carrier into
a vacant hot zone. In the hot zone, the
strong radiant heat rapidly and homo-
geneously heats the parts to treatment
temperature according to the individual
recipe, such as carburization, annealing
and diffusion. Temperature and process
gas supplies are controlled independently
in each hot zone. After carburizing, the
telescoping loader returns the workpiece
carrier with the processed parts to the
quench chamber. The chamber is ooded
with quench gas (nitrogen) to a maximum
pressure of 6 bar. The high powered gas
blower directs the quench gas ow over
the parts for rapid and homogeneous
quenching. Subsequently, the chamber is
vented to atmosphere and the carrier con-
taining the processed parts is transported
out of the chamber. The external handling
system disassembles the workloads and
transports them to the respective stations
for further processing.
