Salzgitter Flachstahl, Germany, has awarded SMS Siemag a contract to revamp the head of the casting machine of continuous caster No. 2 at its Salzgitter location. The revamp is expected to make the casting process safer and increase plant availability.
SMS Siemag is delivering a new mould, a hydraulic resonance oscillator tailored to fit into the limited installation space and the first segment. The existing cooling chamber, the hydraulic equipment, the utilities supply as well as the electrical and automation systems will be adapted by SMS Siemag as part of the customer-specific modernisation concept. SMS Siemag is implementing its newly developed ‘Delta Speed Adjustment’ process in the plant, by way of which slab widths can be adjusted efficiently and with a high degree of flexibility. With Delta Speed Adjustment, the taper of the narrow faces is adjusted simultaneously with the width change itself. This saves time and shortens the transition length. Furthermore, the casting speed does not have to be reduced for the adjustment process, and the planned production is not impaired.
Installation and commissioning will take place during a planned plant shutdown in September 2015. Continuous caster No. 2 was originally built by SMS Siemag in 1973. SMS Siemag already delivered and installed a new ladle turret on continuous caster No. 2 in 2013.
