Hot strip mills for steel

Hot rolling
Hot strip mills

You'll appreciate X-Roll® hot strip mills from SMS group as all-round plants for high-quality hot strip. They are designed to produce flat steel from thin strip with a minimum final gauge of 1.2 millimeters to high-strength pipe steels up to 25.4 millimeters thick, including stainless steel grades. Implemented here are many technologies that ensure excellent hot strip quality as well as high cost efficiency and availability.

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.
