Refractory Ceramic Distributing Launder for Aluminum billet casting
Distribution launder is used in the casting mould table of the casting machine, especially suitable in hot-top casting for aluminum and aluminum alloy.
Distribution launder is made from aluminum silicate fiber and ceramic composite material. It has the features of high strength; resistance to etching liquid aluminum, long-term use is not dross, long life, and good insulation effect. It is the best choice for casting platform.
Distribution launder common size for billets like 3", 4", 5", 6", 7", 8", 9", 10", 12", 14", 16", 18 ", 20 ", and also can produce different sizes according to customers' requirements.
