Heavy plate mills for steel

Hot rolling

Whether skyscrapers or offshore platforms, giant bridges or slender wind turbines, pipelines, gasholders for enormous pressures, excavators, mobile cranes, container ships, luxury liners - heavy plate covers a vast range of applications. Ideal for all these products are heavy-plate mills from SMS group. They also allow steelmakers to supply plates with tailor-made material properties designed for tight geometrical tolerances. As a system supplier, SMS offers you the complete technology spectrum from reheating furnaces to heat treatment including mechanical engineering, electrical and automation systems, and process know-how.

Heavy-plate mill designs

Heavy-plate mills

Each heavy-plate mill features its own individual layout. That depends on the product mix, the product geometries, and the installation site. Common to all mills are the main process sections: reheating furnaces, mill area with one or two reversing 4-high stands, plate cooling and hot plate leveler, cooling beds, shearing line, finishing line, heavy plate line, and heat treatment line. We apply all our hands-on experience to develop the optimum layout in close cooperation with you.

Flexibility in leveling
Plate leveling

Today, the market demands for heavy plates with excellent flatness and low residual stresses. That's why we design and supply pre-levelers, hot plate levelers and cold plate levelers with special features to guarantee the demanded flatness throughout the entire production process.

Shearing iamge

Shears for 60 mm plate thickness

Our heavy-plate shears are designed to cut plates up to 60 mm thickness with exact width and length and excellent edge quality.

Innovative designs and technology
Heat treatment

New on the market are our latest furnaces and quench systems. They make heat treatment of heavy plate more efficient, precise, and flexible.

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.
