Severstal awards Danieli with order for new special steel rolling mill

Russian steelmaker AO Severstal has awarded Danieli with an order for the supply of a new rolling mill for special steels to be installed in Cerepovec. The new plant will produce 1 million t/a of 5.5 to 32-mm-dia smooth wirerod and coiled bars for the engineering and automotive industries and 8 to 16-mm-dia quenched rebar for construction purposes. Mill startup is planned within end of 2022.

Danieli will provide all the technological equipment, automation and advisory services. A Danieli Centro Combustion walking beam reheating furnace will bring to rolling temperature 12-m-long, 150-mm square-billets, at a pace of 170 t/h. A single-strand high-speed roughing mill made of horizontal and vertical housingless stands will feed two independent wirerod lines and a garret coiler to produce the bigger diameters.
The intermediate mill is composed by horizontal housingless stands while the finishing stand group consists of cantilever stands and two separate fast-finishing blocks (six plus four passes) in order to achieve better macrostructure.
Two oil-film bearing laying heads will lay wraps on a 100-m cooling conveyor designed for sorbitezed process.
All coils will be processed along a Sundbirsta vertical trestle system.
The entire mill will be powered by Danieli Automation electrical motors and drives, and controlled by L1, L2 and Q3 technologies.
