9th ECCC European Continuous Casting Conference – ECCC 2017

Strand guide rollers in continuous casters are crucial components for an optimal process for the production of high-quality steel grades. The properties of these rollers greatly influence the quality of the slab produced. The most commonly used designs so far have been the axle roller and the solid roller. Through an intensive exchange of experience with the caster manager of continuous casters from various suppliers, SMS group has succeeded yet improvement potential in the existing roller concepts. Especially the dismantling and assembly of strand guide rollers play an important role in maintenance. Further it is especially the axle roller and roller with split bearings, whose design obstruct a sufficient internal roller cooling. The STEC-Roll® reduces maintenance costs and enables different types of cooling concepts corresponding to the produced steel grades. A variation of the internal roller cooling allows dry casting of challenging steel grades such as micro-alloyed heavy plate or API grades. With the STEC-Roll® in combination with a suitable cooling concept, all target temperatures can be attained, even in the crack-susceptible edge zone. SMS presents some details about the quick and easy installation and dismantling as well as experience reports.
