Siemens to Modernize Bar and Bar-in-Coil Mill for Shougang Tonghua

01/10/2012 - Shougang Tonghua Iron & Steel has placed an order with Siemens VAI Metals Technologies to supply equipment to modernize the company’s bar mill in Tonghua.

Shougang Tonghua Iron & Steel Co. has placed an order with Siemens VAI Metals Technologies to supply equipment to modernize the company’s bar mill in Tonghua. The project will also optimize the entry side of the bar mill’s cooling bed and the Garrett reel in the bar-in-coil production. This is intended to reduce wear on the workpieces considerably, and to improve the quality of the final products.
 
The bar and bar-in-coil mill, originally installed in the Beijing area by Siemens (2006) will be relocated to Tonghua in the Jilin province. With an annual capacity of 600,000 tons of straight and coiled quality steel bars, it can produce bar stock with diameters from 14 to 80 millimeters and coiled bar with diameters from 14 to 50 millimeters.
 
Siemens is engineering a new entry section for the bar mill’s cooling bed with the intention of minimizing wear on the surface of the bars. Two new saws will also be added to the bar mill for cutting steel bars to size.
 
In addition, the bar-in-coil mill’s two Garrett reels — in which coils are formed — will be equipped with a new pre-bending device that will invert the coiling direction and further reduce the mechanical load on the bar during coiling.
 
Siemens will also supply the associated basic automation for both plant sections as well as a mechatronics package for sawing, and also will support Shougang Tonghua with the installation and commissioning. Completion of the modernization is scheduled for mid-2012.
 
Shougang Tonghua is part of the Shougang Group, one of China’s leading steel producers.
