The RIVA mill in Sam Montereau, France, already has good experience with Sund Birsta compactors and coil handling systems and has been successfully using earlier versions for more than 30 years now.
The new coil compactor, Sirius, will use mainly electro-mechanic
drives for its functions and only limited hydraulic power; all systems
will be on board, thereby limiting installation and commissioning time.
The Sirius will use approx. 20% energy consumption compared to
conventional compactors on the market. Carriages travel with electrical
gear motors quickly and with low force. Final compacting is then done by
hydraulic cylinders with short stroke and high force. The press forces
will be kept within the frame work of the two press carriages since they
are locked together before final compacting is done. Wire feeding is
entirely electrical driven using frequency converters to control speed.
The new fully electrical binding unit KNBe has also been introduced and
will use servo motors to operate. With servo drives a vast range of
analyzing tools are available and these can be used for generating
feedback for preventive maintenance. The electrical binding units also
avoid any risk of getting hydraulic oil on the coils. The Sirius will
help mills save energy while, at the same time, speed and efficiency are
optimized. Machine dimensions are smaller than traditional compactors
and this will therefore enable substituting older machines on existing
foundations.
