"We want encoders with a long service life"
At Outokumpu's hot rolling mill in Avesta, Leine & Linde's products have been chosen for speed control and position-monitoring. The mill produces top-quality stainless steel – a task that requires a production process that is as safe and problem-free as possible.
Stainless steel accounts for 5 per cent of the world's steel production thanks to its many areas of application – plus it is fully recyclable.
Stainless steel accounts for 5 per cent of the world's steel production and it is the fastest growing metal market. At one of Outokumpu's plants, the hot rolling mill in Avesta, they are concentrating on producing steel strip from huge stainless steel ingots or 'slabs'.
Leine & Linde's encoders highly praised at hot rolling mill
The production line at the hot rolling mill uses a number of encoders from Leine & Linde. Most are used for controlling speeds, and the robust 861 incremental hollow shaft encoder is a popular model. The "shear" that cuts the strip is fitted with a Leine & Linde 13-bit absolute encoder that is used to check positioning.
Electrical manager Mikael Larsson, who works in the hot rolling section, explains that they chose Leine & Linde encoders a few years ago.
"The hot-rolling environment is extremely tough, and encoders have to withstand dirt, oil, high temperatures, vibrations and shock. We are very pleased with Leine & Linde's encoders and with their cooperation. The stainless steel strips and sheets have a high alloy content and are heat-resistant. The tiniest defect can be disastrous, and top quality is what counts here," concludes Mikael Larsson.
