reheating furnace chambers for slabs, slab shears, slab turnover devices as well as complete hot processing (rolling and pressing etc) in rolling mills. In metallurgical plants and power stations, Pieper’s furnace systems are used for slag flow control and for melt control in aluminium plants. Detailed information on furnace television systems is included in the FRS-T technical documentation, available on the request.

used; and place of installation in furnace (rigid installation or automatic retraction system). Thanks to Pieper GmbH’s many years of experience internationally, many more applications – apart from those stated above – can be implemented if required by the customer. The company’s main strength refers to the design and construction of complete and tailor-made furnace systems for any application. Other applications of Pieper’s furnace television engineering cover slab and continuous casting plants, slab transport systems, monitoring of

manufactures a number of furnace probes, including optional accessories, for process monitoring in blast furnaces, melters, vacuum containers (VD/RH) and other types of furnace chambers. When planning and constructing furnace probes, all specific local conditions and requirements are considered at an early stage, such as: the type of furnace and melt; different furnace wall thicknesses; required probe length; probe view angles; temperature at place of installation; temperature at probe tip; ambient conditions in furnace; heating media

High-speed plasma annealing for stainless steel, Cu and Ni alloy tubes

exchanger, food processing, chemical, aerospace, aviation and automotive. Trials on the new line can be performed at Plasmait’s facility in Austria. Plasma annealer and plasma cleaner can process different types of materials used in applications such as fine precision tubes, medical tubes, hydraulic tubes, capillary tubes, heating element tubes, heat exchanger tubes, thin-walled tubes, and various tubes in automotive, aerospace and instrumentation applications.

accuracy. Rapid heating and reduced time of recrystallisation results in fine grain size with uniform crystal structure. This in turn improves material formability, and its susceptibility to bending and further drawing. PlasmaANNEALER can cold start production in a few minutes and can be stopped immediately. This avoids the lengthy heating-up and cooling-down times and associated energy costs that are symptomatic of a conventional furnace. Ion sputtering on the material surface results in fine dry surface cleaning and surface oxide removal, which have proved beneficial to applications with demanding surface requirements in sectors such as medical, heat

PLASMAIT has introduced a new PlasmaANNEALER for precision, thin- walled and small diameter, tubes. The annealer can be used for tubes made of copper, titanium, alloy, stainless steel and nickel alloy. Plasma improves annealing speeds on small diameter and small cross- section tubes and improves surface quality of the finished tubes. Plasma annealing can be performed in-line with tube welding or drawing substituting multiple lines of a traditional tube furnace. The annealer features compact design, high energy conversion efficiency, and low gas consumption, and gives the operator the ability to target mechanical properties with
