Steel mills require durable, efficient machinery to boost productivity and cut costs in 24/7 operations. Cassette systems—comprising a terminal tractor, self-loading translifter, and cassettes—are a cost-effective solution for handling slabs, coils, sheets, plates, and scrap. For hot slabs, thermo cassettes with heat insulation prevent rapid cooling, protecting material quality and saving energy by reducing reheating needs in subsequent processing.
