Order for steel tube annealing machine PLASMAIT reports that 2015 was an exciting time for its team in Austria. One of the orders received by the company last year included an annealing line for precision stainless steel and nickel alloy tubes with OD range 0.6-10mm. The order reaffirmed the success of Plasmait in stainless steel heat and surface treatment applications that now include wire, tube, strip and rope annealing and hardening.

The line was built for a producer of small-size precision tubing whose prime concern was the quality of recrystallisation, as well as clean, bright and scratch-free finish of the tube surface. Plasmait’s solution offered the client a modern, computer-controlled facility designed for ease of use and minimal environmental impact. Plasmait now offers annealing lines with outputs of up to 170kg/h per line for austenitic, and more for martensitic stainless steels. The new facility occupies a fraction of the space that would be required by a conventional multi-line annealing furnace of the same capacity. A single plasma line can substitute around 20 traditional lines. The annealing line features high energy conversion efficiency, low purging gas consumption, quick string-in, and computer-based quality control. PlasmaAnnealer can cold start production in a few minutes and can be stopped immediately. This avoids 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 dry surface degreasing and surface oxide removal, which have proved beneficial to applications with demanding surface requirements in sectors such as medical, heat exchanger, food processing, chemical, aerospace, aviation and automotive. Plasmait also sold annealers for producers of fine medical tubes with sizes down to 0.2mm OD. The annealing speeds on small-size tubes are high enough to allow annealing to be performed in-line with drawing. Tube producers now require fewer take-ups and payoffs, which reduces the total cost of equipment.
