Steckel mill stand for 1.3 million tons of heavy plate per year

Shandong Iron & Steel Group Rizhao Corp. Ltd. (Shandong Rizhao) has ordered a Steckel/plate mill from SMS group. The order comprises the complete engineering package, mechanical key equipment, all electrical and automation systems as well as process know-how.

The slabs for the rolling mill will be produced by a new slab caster also to be supplied by SMS group. Thanks to the high slab weight of 57 tons, the envisaged output of 1.3 million tons per year can be achieved with only one mill stand.

The rolling line will comprise a Steckel mill stand with a connected edger at the entry side. The first passes are simple reversing flat passes. Rolling stock of a thickness of 25 millimeters or less will be coiled in the Steckel furnaces to keep the specified temperature. Shandong Rizhao will be able to roll strips up to a length of 600 meters, which will be divided to mother plate lengths of maximum 50 meters by a “flying” cross-cut shear. To set the desired strip geometry, the mill stand will be equipped with state-of-the-art actuators including CVC® plus technology with integrated work roll bending.
