HIGH-THROUGHPUT STEEL BAR TEMPERING

Q&T Bars

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.

KEY FEATURES

LOW-DISTORTION TEMPERING

Low operating costs

Tempering without decar­burisation

Compact modular design

TECHNOLOGY

Tempering

Flexibly configurable to meet individual requirements

The quench and temper lines from SMS Elotherm can be quickly configured for new dimensions, steel grades or special features, such as tubes with upset-forged ends. High production rates (tonnes per hour) are possible with induction technology, even with variable lengths and diameters.

Another advantage of the SMS Elotherm precision induction process is that high uniformity can be achieved in tempering with regard to hardness, mechanical properties and microstructure.

Smooth commissioning of quench and temper machines

The induction quench and temper lines from SMS Elotherm can usually be installed considerably faster at the customer’s site than lines with conventional furnace technology. In addition, commissioning of the induction lines is impressively easy, allowing production of finished products to commence much earlier. With induction tempering lines from SMS Elotherm, new methods can be developed quickly, enabling simple implementation of prototype production for end users.
