Induction tempering: the modern alternative to oil tempered wire

OIL tempering (OT) is recognised as the traditional method of producing spring wire for cold coiling. However, due to environmental concerns with this process, induction tempered (IT) wire is growing in popularity. Additionally, spring makers for cold coiling applications are moving to IT wire due to its mechanical properties. Ori Martin SpA, of Brescia, Italy, placed its trust in Inductotherm Heating & Welding Ltd and the Radyne brand to purchase its first Radyne spring wire line for the production of IT wire. To date, Radyne has supplied 15 of these high efficiency lines with production capacities of 1,500 to 3,000kg/hr. Typically the Radyne lines treat SAE9254 or equivalent and are also used to treat more exotic alloys with vanadium and nickel additions. As main project contractor, Inductotherm Heating & Welding is responsible for the complete heat treatment process, from pay- off to take-up. With these established Radyne lines there are no harmful chemicals to pose a risk to operator health or the environment. The quench tanks only require tap water as the quenching medium. Induction heating technology generates heat directly within the wire and only when the line is in production, minimising start-up times and energy losses as well as ensuring maximum power efficiency.
