It is reported that ArcelorMittal has awarded ABB Automation of Germany the contract for modernizing the cold rolling mill and pickling line at Krakow works in Poland formerly known as Huta Sendzimir.

Low alloy sheet steel is produced on the 4 stand tandem rolling mill and the connected single stand skin pass mill stand. The order with a value of approx. 14 million euros includes the complete modernization of the mechanical and electrical components. The essential part of the project are the new DC supply units for the main and auxiliaries drives, while retaining the DC motors, and the completely new motor control centers. Moreover the rolling mills will be fitted with new work roll bending control systems and completely new measuring systems for thickness and flatness control.

ABB will also supply the completely new level 1 automation systems including the technological control systems equipped with AC800PEC high speed controllers for rolling mill applications. Furthermore the scope of supply includes the Level 2 systems containing the mathematical models for the tandem rolling mill and the pass schedule computer for the skin pass mill. ABB is also responsible for all engineering services, project management, installation and commissioning.

In addition to the modernization of the cold rolling mills the refurbishment of the pickling line will start in the same mill. ABB will supply the new AC drives, the welding transformer, and the motor control centers for the new hydraulic system and the new DC supply units for the existing DC motors of the main and auxiliary drives. This project too includes level 1 and level 2 automation and all engineering services, project management, installation and commissioning.
