PSM® Mill block


Innovative 3-roll technology

PSM® stands for ”Precision Sizing Mill“. It also stands for wire rod and bar production that meets today‘s demands for top flexibility and process transparency. Always keen to achieve even better sustainability, SMS further improved the process for you. How? By integrating our MEERgauge® cross-section measurement system.

An outstanding advantage of the innovative 3-roll technology is that it positions the rolls using hydraulic cylinders – even under load. Combined with our TCS technological control system, this feature enables you to fine-tune your rolling processes in real time. That way you benefit from even better finished products. It’s another plus that the 3-roll PSM®, which has been successfully in use since 2006, can be operated in fully automatic mode with MEERgauge®.

Greater precision, cost efficiency, and sustainability

Included in our new technology is a precision laser gage for measuring the crosssection with pinpoint accuracy. You can also run a highly dynamic monitor control system. Then there is our MEERgauge® system which automatically corrects dimensional and temperature fluctuations in the preform. That ensures perfect end products due to rolling tolerances of 1/8 DIN EN 10060 and higher. What that means for you is lower peeling volume and labor costs. Plus: rolling with improved dimensional accuracy cuts both energy and material costs. All in all, the PSM® process plus integrated MEERgauge® system offers you greater precision, cost efficiency, and sustainability.

First-class reference for a successful upgrade
The main products of Deutsche Edelstahlwerke at its site in Siegen-Geisweid are materials for the automotive industry. The company commissioned SMS group in 2011 to expand its 3-roll PSM®. Our customer planned to include a precision cross- section measurement system with integrated automatic size control. As soon as the project was completed, the MEERgauge® system boosted both the efficiency of the mill and the quality of the steel produced.
