SSAB Iowa, USA ordered twelve STEC roll lines from SMS Siemag, Germany for use in the casting bow of its continuous slab caster in Montpelier, SSAB Iowa. The STEC-Roll optimises the casting process and sets new standards for cost-efficient maintenance.
SSAB chose the STEC-Roll for the roll’s inside cooling with revolver bores, which enables a versatile secondary cooling concept for the casting of elaborate steel grades. The STEC-Roll will replace two driven and ten non-driven rolls in one segment in the existing continuous slab caster. The STEC-Roll will replace rolls with maintenance-prone split bearings.
The STEC-Roll receives customised deposit welding in the service workshop at SMS Millcraft, USA, extending the service lives of the STEC rolls even more. The continuous caster was supplied by SMS Siemag in 1996.
