Molten metal is transferred from the remelt\/holding furnace through a launder line to the casting machine. If the launders are not covered and heated, the metal cools as it travels the length of the launder line. Because casting machines require metal at a specific temperature, the operating temperature of the furnace is related to the thermal efficiency of the launder line. Therefore a thermally efficient launder line, allowing a lower operating temperature in the furnace, usually results in energy savings and reduced hydrogen absorption in the molten aluminium.<\/p>\n
When launders are not fully preheated, heat is absorbed from the molten metal until the launder line reaches equilibrium. This usually results in the first metal of each casting being drained off into pans until the temperature stabilizes and the metal can be redirected into the casting machine. The preheat temperature and the thermal efficiency of the launder line affect the amount of metal lost each casting and the time required before the system reaches equilibrium.<\/p>\n

\nThe metal going into the casting machine must be free of \u201cinclusions\u201d. The surface quality of the launders can affect the risk of refractory pieces being included in the metal flow.<\/p>\n
For a number of years Adtech has fabricated high quality refractory casting line launders.<\/p>\n
Through much time and energy spent on research and development, Adtech has developed forming and casting techniques that result in launders with an unparalleled quality of surface finish.<\/p>\n
Further, Adtech’s specialized forming techniques reduce stresses on the launders during deforming. This reduces the occurrence of micro-cracks and permits the launders to retain their maximum mechanical and thermal shock resistances.<\/p>\n

\nAdtech casts launders in several different materials depending on the specific operating conditions. Different materials may even be used in the same installation according to the requirements of different “zones”.<\/p>\n
\"D\u00f6k\u00fcmhane<\/p>\n
Adtech’s engineering department has developed a system of non-steady state heat transfer calculations that permit it model and optimize the thermal performance of casting lines based on different refractory, insulation and pre-heat configurations. They can also design the launder geometry to specific flow rate, maximum velocity and time of retention criteria.<\/p>\n
All of the above allow Adtech to provide high performance casting line launders<\/a>, and complete casting line launders solutions, adapted specifically to client needs.<\/p>","protected":false},"excerpt":{"rendered":"
