In strip casting, the steel is cast between two rolls, producing directly a strip of around 3 mm thickness. The steel is cast between two water-cooled casting rolls. This results in very rapid cooling and high production speeds. The major advantage of strip casting is the large reduction in capital costs, due to the high productivity and integration of several production steps. The technology was first applied to stainless steel, and later strip casting of carbon steel was also demonstrated.

Strip casting technology leads to considerable capital cost savings and energy savings. It may also lead to indirect energy savings due to reduced material losses. Operations and maintenance costs are also expected to drop by 20–25%, although this will depend strongly on the lifetime of the refractory on the rollers used in the caster and local circumstances. Energy consumption of a strip caster is significantly less than that for continuous casting (US EPA, 2010. p. 24).
