Severstal awards Danieli with order for new special steel rolling mill

Russian steelmaker AO Severstal 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 Mtpy 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.

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 tph. 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.

Mill startup is planned within end of 2022.
