ArcelorMittal Poland will invest over PLN 100 million in its cold rolling mill in Kraków in Poland. As part of the program, the company implements three projects: replacement of the rolling mill motors, modernization of the sheet etching line and the purchase of a new grinding machine. The end of the program is scheduled for the end of this year. The first project has already been completed, and consisted in replacing three DC motors in one of the rolling stands of the rolling mill with one AC motor.Modernization of the sheet etching line is planned for the fourth quarter of this year. Hot-rolled coils must be cleaned of the so-called scales, i.e. mixtures of iron oxides formed during hot rolling. Etching, i.e. cleaning sheet metal from surface defects in hydrochloric acid solution, takes place on a 250-meter-long etching line. Thanks to automation, the processes performed before the material enters the line will be shortened. The number of hot-rolled steel coils prepared simultaneously for pickling will increase, and the packaging tape will be removed by a robot. Full automation of the process is also waiting for the exit section of the line: a new coiler, an automatic coil tying machine and new coil transport trolleys will be installed.In turn, a new, fully automatic grinder will be installed in the roll grinding plant, working with high precision - the deviations in the surface of the polished rollers will not exceed 0.002 mm per meter.
