ALUMINIUM SMELTING INDUSTRY
is released. Also during the welding process,
welding gas appears. In order to effectively
contain these impurities, a special cyclone filter
has been installed on the ASRL.
The advantages of HMR’s ASRL are:
• The line is completely automated and
requires just one supervising operator
• The process is efficient and very safe for
the floor personnel
• It reduces repair down-time to the
minimum
• There is no need to remove the anode
rods from the conveyor during stud
replacement
- Fewer anode rods are needed in the plant
(estimation 2-4%)
• Studs are replaced exactly according to
the procedure set up by the customer.
Procedure, line of action
HMR’s ASRL brings the studs distinctively to the same condition as on the anode yoke
Measuring station: All complete anode yokes
and rods are transported on the power and
free conveyer to HMR’s ASRL measuring station.
Each anode stud is checked against the
wear and tear limit set by the customer. Anode
studs with an acceptable wear-and-tear level
are returned to the plant. A bypass on power
and free conveyer brings anode studs with
wear and tear above the limit to the ASRL
for processing. The measurement station collects
historical data which later can be used for
statistical purposes.
Cleaning station: The HMR’s ASRL system
sends a signal to the robot-operated cleaning
device and indicates which stud is to be
cleaned. In front of the cleaning station there
is a conveyor block up. The robot with chain
centrifugal blast cleaning device starts to clean
