The CMT® technology, when compared to a traditional minimill of same capacity, provides steel producers with an efficient tool with estimated saving of approx. 20 Euro/t in transformation cost that in addition to the reduced initial investment cost results in an estimated competitive advantage of 10 to 25% over conventional minimills.
The worldwide steel industry is seeking strategies for compact and efficient production units utilizing local resource and distribution markets. This development originates from the requirement of a sustainable, energy efficient and cost-optimized steel production process. To meet this market demand SMS developed the CMT® Continuous Mill Technology, process.
Aim of the CMT® process is to combine billet continuous casting directly with the rolling process. Hence, energy consumption and yield losses can be reduced significantly compared to conventional dis-continuous processes. To maximize these and other benefits of the directly linked casting and rolling the casting machine is casting on one strand only with speeds as high as the required entry speed of the rolling mill, hence allowing a real endless production of rolled product with uninterrupted sequences of approx. 23 hours.
