Sweden, Stockholm: During the planned maintenance outage at SSAB Special Steels in Oxelösund at the beginning of December, ABB replaced the control system for the power supply of the rolling mill. However, during the planned restart, a transformer broke down.
After repair, during the restart of the powertrain of the rolling mill, there was another breakdown of one out of six similar power transformers, reports Cision.
ABB is now repairing the transformer and conducting a renewed trouble shooting of the control systems, which is expected to last for three weeks.
"It is a top priority for ABB to find a solution together with SSAB. ABB has mobilized all expert resources needed to find a fast and reliable solution," said Johan Söderström, Managing Director, ABB Sweden.
