In modern tube production, induction heating and welding technology is a basic prerequisite for high productivity, quality and profitability.
Elotherm has many decades of experience in tube machines, as well as the latest process expertise. On that basis, Elotherm develops and supplies solutions along the entire tube production chain. Perfectly integrable and cost-effective.
With longitudinal welding, an endless strip is formed into a tubein a continuous rolling process. The opposing strip edges are heated to the welding point by an inductor carrying a high-frequency alternating current and pressed together by rolls. The resulting high-quality weld does not need any additional materials.
The SMS Elotherm induction machines for tube annealing consist of an induction heating section with an attached quenching device, followed by an induction annealing section to configure the desired hardness parameters. The most impressive features of the quench and temper lines from SMS Elotherm are their high efficiency, accuracy and versatility.
The quench and temper lines for long products, such as steel bars, have an induction heating section and a quenching section, followed by tempering induction coils. The heating and tempering coils are usually divided into several controllable zones. This has the advantage that the last zone in each case can be used for homogenisation, austenitisation, solution annealing (for stainless steels), or hardness adjustment.
On modern production lines, the quench and temper machines from SMS Elotherm are the standard for tempering tube and bar material. The most impressive features of the quench and temper lines from SMS Elotherm are their high efficiency, accuracy and versatility.
The long-standing know-how in the induction heating of steel makes the SMS Elotherm to a reliable partner! We offer heating systems for rolling long products and flat products, for strip heating, forging heating, crankshaft hardening, surface hardening, ring hardening, bar hardening and much more!
