Vacuum furnaces is a relatively economical method of oxide prevention and is most often used to braze materials with very stable oxides (aluminum, titanium and zirconium) that cannot be brazed in atmosphere furnaces. Vacuum brazing is also used heavily with refractory materials and other exotic alloy combinations unsuited to atmosphere furnaces ...
BVCu-1x is OFHC, vacuum-grade, for furnace brazing of steels, stainless steels and nickel alloys. Oxygen-containing copper is incompatible with hydrogen-containing atmospheres which cause its embrittlement. Cheaper than silver, but requires higher processing temperatures and is oxidation-prone. Used in fluxless vacuum brazing of stainless steels.
Vacuum furnaces are used to carry out processes such as annealing, brazing, sintering and heat treatment with high consistency and low contamination. Characteristics of a vacuum furnace are: Uniform temperatures in the range. 800–3,000 °C (1,500–5,400 °F) Commercially available vacuum pumping systems can reach vacuum levels as low as 1 × ...
Materials for use in vacuum are materials that show very low rates of outgassing in vacuum and, where applicable, are tolerant to bake-out temperatures. The requirements grow increasingly stringent with the desired degree of vacuum to be achieved in the vacuum chamber. The materials can produce gas by several mechanisms.
Ipsen's industrial furnaces - vacuum furnaces, atmosphere furnaces and pusher-type furnaces - are used for the following heat treatment processes: hardening, quenching, tempering, carburization, carbon nitriding, nitro carburization, bright tempering, annealing, vacuum brazing, temperature brazing, plasma nitriding
Induction brazing is a process in which two or more materials are joined together by a filler metal that has a lower melting point than the base materials using induction heating. In induction heating, usually ferrous materials are heated rapidly from the electromagnetic field that is created by the alternating current from an induction coil .
An industrial furnace, also known as a direct heater or a direct fired heater, is a device used to provide heat for an industrial process, typically higher than 400 degrees Celsius. [1] They are used to provide heat for a process or can serve as reactor which provides heats of reaction.
Electron-beam furnaces are used for production and refining of high-purity metals (especially titanium, vanadium, tantalum, niobium, hafnium, etc.) and some exotic alloys. [1] The EB furnaces use a hot cathode for production of electrons and high voltage for accelerating them towards the target to be melted.
