New diameter measuring systems for Korean mills

ZUMBACH Electronic has won a contract from POSCO Pohang works in Korea for ten Steelmaster diameter/profile measuring systems. The new systems will partially replace existing gauges or complete unequipped locations in the finishing sections of the company’s #1, #2 and #3 rod mills. All gauges are equipped with six Odac high speed laser scanners (in six axes), delivering 6,000 calibrated measurements per second, as well as with the latest hardware and software concept. The systems will be fully networked over Ethernet with POSCO’s material flow and QC control system. Delivery of the compact gauges, which require close-to zero maintenance, is scheduled for early 2011. POSCO has operated a number of similar Steelmaster gauges in the intermediate sections since 2008. Zumbach Electronic AG – Switzerland Fax: +41 32 356 04 30

Chinese orders for cold rolling mills received by SMS Siemag AG

NORTHEAST Light Alloy Co, Ltd (NELA), China, has ordered a new CVC ® plus aluminium cold rolling mill in six-high design from SMS Siemag. With the new aluminium cold rolling mill, NELA is entering modern production of high-quality aluminium strip products. In addition to various finished products, input stock for foil manufacture will be rolled on the CVC plus six-high stand. The new SMS Siemag cold rolling mill, which will constitute the central production unit of the works in Harbin, is designed for a capacity of 85,000tpy and processes incoming strips with entry gauges of maximum 8mm and widths of up to 1,900mm. The minimum final gauge is 100μm, and the maximum coil weight 21t.

The six-high stand is equipped with CVC plus intermediate-roll shifting and with multizone roll cooling for influencing strip flatness. A Hot Edge Spray system (HES) is provided to influence strip flatness in the strip edge area. The Dry Strip system (DS) installed in the exit section of the mill ensures that the residual oil on the surface of the rolled strips is kept to a minimum. A coil preparation station, a coil conveyor system and the full range of utility systems complete the mill stand. SMS Siemag has also received an order from Novelis do Brasil Ltda, Brazil, to supply a new two-stand cold rolling mill for aluminium alloys. The two-stand tandem mill is said to be the first of its type in South America.

The new tandem cold mill will be used for manufacturing can stock for the beverage industry. The products will comprise strip in widths of up to 2,000mm and with a minimum final gauge of 0.15mm. The mill will be designed for an annual capacity of 330,000t. The key components of this high- capacity mill are highly efficient roll bending systems, multizone roll cooling and a hydraulic roll adjustment system. A coil preparation station, an off-line strip inspection facility and a pallet transport system from SMS Siemag complete the rolling mill.
