PG Series Heated Launder
Launder systems are electrically heated and controlled by thermocouples. All
parts that come in contact with the molten metal are made using special silicon-carbide
ceramic, which has a long history of providing excellent service. Since the launders
are electrically heated, there is very little or no heat loss from the
furnace to the mold. This minimizes the need for super-heating of the metal in the
furnace, and further improves metal quality and reduces costs.
The metal moves up from the pump through a short unheated section and
then enters an 85 degree elbow which is connected to a horizontal section.
The horizontal section is at a 5 degree incline, which allows the launder
to be self-draining when the pump is shut down. The horizontal section is then attached
to the mouthpiece.
There are several different mouthpieces available depending on your
needs, such as roll over, direct low-pressure, tundish, gravity, or double
low-pressure (i.e. two molds in one press). Special mouthpieces can be designed
according to your individual needs.
Since the launder carries a large volume of metal every week, it is
important to clean it every week. In most cases, a spare is heated
one day in advance and put into service, while the other one is cleaned
and re-gasketed. The launder transport cart makes this changeover fast and easy.
