In September 2014, Swedish steel producer SSAB awarded SMS Siemag (www.sms-siemag.com) Germany, the order to modernize the tandem cold mill at its Borlänge works. The rolling mill, supplied by SMS Siemag, has been in operation since 1970. The most recent revamp of the mill in 2004 was also performed by SMS Siemag.

The five-stand tandem cold mill has an annual capacity of more than 1.2 million tons. It produces carbon steel strips in widths ranging between 600 and 1,550 millimeters and with final gages down to 0.32 millimeters.

To be able to roll new materials cost efficiently and with better flatness on the tandem mill, SMS Siemag will supply new mechanical systems for mill stand No. 4. These will include systems for roll gap lubrication, roll cooling and an oil wiper system.

The revamping work, which will take one week, is scheduled to take place during the regular shutdown in summer 2015. In mid-August 2015, SSAB will be able resume production on the revamped tandem cold mill.

 

SMS Siemag AG and SMS Meer GmbH are both companies of SMS group which, under the roof of SMS Holding GmbH, consists of a group of companies internationally active in plant construction and mechanical engineering for the steel and nonferrous metals industry.
