For maximum plant efficiency, improved and safer working conditions,
the economical process for handling molten metals is through a gravity-feed
launder system. The Lindberg/MPH launder system designed along the
same parameters as the Holimesy electric holding furnaces, has proven
to reduce energy costs by at least 1/3. This cost-effective, energy-efficient
alternative to conventional outmoded and hazardous molten metal transport
methods can be adapted to fit new or existing facilities.
BENEFITS
REDUCED HANDLING COSTS
Molten metal flows from the central melting furnace through the
launder system to the casting station by gravity feed. This significantly
reduces time and labor expenses as well as the equipment investment
normally required for manual transfer methods.
LOWER METAL LOSSES
The use of one central melting furnace plus the fully covered
design of the launder substantially reduces metal loss due to
oxidation.
SAFER WORKING CONDITIONS
Lindberg/MPH launders generate no hot gases or combustible products
and are completely covered, eliminating the hazards of exposed
molten metal and radiant heat to the work area.
GREATER ENERGY EFFICIENCY
Extensive use of ceramic plates and fiber insulation minimizes
energy consumption. The typical Lindberg/ MPH launder system is
rated at 560 watts per foot of launder but uses only about 300
watts per foot under normal process conditions.
MINIMAL MAINTENANCE COSTS
The low mass ceramic plate lining provides long service life.
launder thermocouples also achieve long life because they are
located between the melt and the insulated launder cover to avoid
corrosive effects of the hot metal. Pneumatic-lift cover sections
make inspection or cleaning easy to perform. Air cylinder can
be on or opposite hinged side to suit.
