CSP® technology

CSP® technology - the leading thin slab technology

Today, CSP® (Compact Strip Production) is the world's leading thin slab technology. Pioneered by SMS group in 1989, it has transformed the world of flat steel production. That's because CSP® has so much to offer - above all: high cost efficiency, a broad product spectrum, and excellent strip quality.



Main data
Full variety of carbon grades such as structural steel, silicon steel, pipe grades, multiphase steel

Strip width:

Compact in design, CSP® produces high-quality hot strip in a single manufacturing line that combines casting, heating, and rolling. Our proven CSP® caster with its patented funnel-shaped mold casts thin slabs in thicknesses ranging from 50 to 90 mm. Next, the slabs go into the CSP® furnace for temperature equalization. Straight after that, the CSP® mill rolls them to final strip thickness.

If you want to grow with the market, CSP® is the perfect solution for you. Starting with a single-strand CSP® plant, you can cost-effectively produce around 1.5 million tons per year. Later, simply add a second casting strand to double your capacity to more than 3 million tons per year.

X-Roll® Oil Bearing

Hydrodynamic roll-neck bearings from SMS group are highly advanced and elementary components of modern rolling mill technology. That's because they support the load-bearing backup rolls. Even under extremely tough operating conditions, they ensure long roll service life and minimal maintenance outlay. This is how roll-neck bearings contribute substantially to meeting the high requirements for optimal final strip geometry.
