Abstract

Strand guide rolls in continuous casters are crucial components for guaranteeing an optimum process for the production of high-quality steel grades. The properties of these rolls greatly influence the quality of the slab produced. The most commonly used designs so far have been the axle roll and the solid roll. A quite new roll concept is the STEC-Roll®. It combines the advantages of the axle roll with those of the solid roll. This paper explains the development of this roll type and shows the current design. The characteristics of the STEC-Roll® are presented in greater detail and are underlined by a number of simulation results. Beside the design itself, the benefits for casting and maintenance are explained, including for example the easy assembly and dismantling or the use of the roll for dry casting. A brief examination is made of the TCO for the STEC-Roll® and an estimation is provided of the exchangeability of this roll. To conclude, an overview on the current applications is presented.
