Melting Technologies.
Retech offers a range of melting technologies to the foundry industry. Plasma arc melting furnaces utilize an arc in a non-reactive gas as a heat source that is applied to the melting of reactive and refractory metals Refractory metals are a class of metals extraordinarily resistant to heat, wear, and corrosion. These properties make them useful in many applications. Household incandescent bulbs contain refractory metals in their tungsten filaments, and nearly all manufactured goods, . Vacuum induction melting Vacuum Induction Melting is a process for melting metal under vacuum conditions using electromagnetic induction. It works by creating electrical eddy currents in the metal which heats the "charge" to melt it. and casting equipment offers precision pouring, repeatable temperature control, a responsive withdrawal system and comprehensive data acquisition. Each of these features is controlled by a PLC/computer package that can offer automatic, semi-automatic and manual operations. Vacuum arc remelting Vacuum Arc Remelting (VAR) is a secondary melting process for production of metal ingots with elevated chemical and mechanical homogeneity for highly demanding applications. can be utilized in the production of titanium, nickel and steel ingots. Consumable electrode casting furnaces are ideal for aerospace and commercial applications and are available in single- and multiple-chamber both of which can be equipped with centrifugal casting Centrifugal casting or rotocasting is a casting technique which has application across a wide range of industrial and artistic applications: - It is used as a means of casting small, detailed parts or jewelry.
capabilities. Electron beam A stream of electrons, or electricity, that is directed towards a receiving object. See electron beam imaging and electron beam lithography. hearth furnaces can be used for the production of rotating grade titanium alloys for aircraft engineer parts as well as a variety of other applications, including refining and consolidation of refractory and reactive metals. The Rototrode non-consumable melting system was developed for the melting and recycling of reactive and specialty metals in a single operation. It utilizes a rotating, water-cooled copper, non-consumable electrode, and melting is performed by a high-current DC arc. This technology can be applied to tilt-pour crucibles.
