SMS Siemag is supplying a 20-roll cold mill of type MB 22B-52“ for a new cold rolling complex being built for Bahru Stainless in Johor Bahru, Malaysia.
The supply scope comprises the design, manufacture, erection, and commissioning of the mechanical equipment, and the auxiliary and ancillary facilities. The SUPAFINE® filter system developed by SMS Siemag will clean and cool the rolling oil. Also included in the order is a water cooling tower for the supply of cooling water to the rolling-oil filter system and to the electrical drives.
The new cold rolling mill is designed for rolling austenitic and ferritic strip grades with a maximum strip width of 1320 mm down to a minimum final gage of 0.15 mm. Maximum rolling speed is 800 m/min. The high deformation allows a thickness reduction of up to 90% to be achieved. The mill stand is equipped with hydraulic roll gap control, roll crown adjusting systems, and a device for shifting the inner intermediate rolls.
SMS Siemag also will supply a payoff group with downstream leveler and a crop shear for reduction of non-productive times. The entry and exit groups contain reversing high-tension reels for strip tensions up to 500 kN.
The core components of the mill are fabricated, pre-assembled, and tested in SMS Siemag's Hilchenbach workshops. The mill is scheduled to go into operation in December 2012.
