SMS group www.sms-group.com has successfully put into operation the new CCM® (Compact Cold Mill) of Aisha Steel Mills Limited (ASML) in Karachi, Pakistan. Since 2015, this has already been the third successful installation of the two-stand type of cold rolling mill by SMS group in Pakistan.
The CCM® at ASML is designed for an annual cold strip production capacity of 500,000 tons. The new facility enables ASML to supply the local market with high-grade cold strip according to international standards and helps the company to make its contribution to reducing the country`s dependency on high-quality cold strip imports. The products rolled on the CCM® are up to 1,250 millimeters wide and down to 0.15 millimeters thin.
The CCM® features two mill stands in four-high design with the proven roll shifting technology CVC®plus (Continuously Variable Crown) by SMS group. CVC®plus is supplemented by further actuators to infinitely adjust the roll gap, for example positive and negative work roll bending. The quality-determining technical highlights of the plant include two X-Shape flatness measurement rolls, installed at the entry and exit sides, together with multi-zone cooling system and automatic flatness control.
The highly productive CCM® is equipped with the holistic X-Pact® electrical and automation system from SMS group. SMS group supplied the complete plant with all auxiliary equipment, such as modern technological instrumentation, emulsion plant, high- and low-pressure hydraulics as well as the fume exhaust system.
With this CCM® from SMS group, ASML operates a high-quality and modern plant technology suited to meet present and future requirements.
