The government owned Chinese producer of special bar quality products Fujian Sangang Minguang has successfully modernized its bar mill line and rolled the first bar on their new KOCKS 3-roll Reducing- & Sizing Block. The RSB 370++/4 in 5.0 designs will further improve the quality of Sanmings SBQ products. Within a major modernization project the decision was made to invest into an upgrade of the existing mill, including the integration of a KOCKS RSB. The proven KOCKS 3-roll technology enables Sanming to meet highest standards in terms of quality. The commissioned RSB 370++/4 is located as finishing unit after 21 stands in H/V rolling mill arrangement and will produce bar in coil within a dimension of 16-48 mm diameters and straight bars within a dimension of 20-90 mm diameters in a 800.000 tonnes per annum mill line. The large-scale modernization through a Chinese EPC contractor comprised additional rolling mill equipment. Despite the KOCKS Reducing & Sizing Block, the project included the supply of H/V stands, shears, a new bar in coil line with finishing facilities and the upgrade of the inspection line. In addition to the mechanical equipment also electric and automation components have been modernized to ensure minimum downtimes, maximum transparency and highest efficiency. Sangang Minguang was founded in 1958 and is one of the most important steel producers in the Fujian province on the southeastern coast of China with 11 million tonnes of steel every year. For more than 70 years KOCKS has stood for highest quality in the steel industry. KOCKS customers benefit from a unique KOCKS knowledge in 3‑roll technology for special bar quality and tube production. Founder Dr Friedrich Kocks, the grandfather of Chairman Mr Ali Bindernagel, innovation took form early in the company‘s history by applying 3‑roll technology to forming tube as well as wire rod and bar. With this technology he created a solution that increases the quality of the rolled product and improves efficiency while reducing costs. It was quickly established that the rolling process itself had an exceptional influence on the metallurgical and microstructure properties of the bar. This is where KOCKS was particularly active in developing innovative processes. For decades now the constancy of progress and new developments has made KOCKS a byword for excellence in the SBQ and seamless tube market, where quality standards are constantly being tightened – driven in part by the stringent requirements of the automotive industry.
