RSB as core technology for SBQ bar mill line Chinese steel producer Changzhou Dongfang Special Steel Co Ltd has signed a contract with Friedrich Kocks for the supply of an RSB® 370++/4 in 5.0 design. The reducing and sizing block will be installed in the company’s special bar quality rolling mill in Changzhou, China. Changzhou Dongfang Special Steel produces three million metric tons of long products annually. Its portfolio includes alloyed carbon steels, spring steels, ball bearing steels, high pressure boiler tube steels and gear steels. The focus is on SBQ products for demanding processing industries. In the city of Changzhou, the steel producer operates three mill lines – one for producing steel profiles and two for steel bars with diameters between 20 and 150mm. The three-roll technology from Kocks allows flexibility and productivity of the production process in the new 800,000t/a SBQ rolling mill, after 21 stands in H/V arrangement. In the small bar mill line, the RSB 370++/4 has been designed according to the individual requirements of Changzhou Dongfang Special Steel, in order to produce straight bars in a finished size range from Ø 20 to 80mm with tight dimensional tolerance.

The RSB 370++/4 will be part of Changzhou Dongfang Special Steel’s new SBQ small bar mill line

The scope of supply includes remote control for stand and guide adjustments; equipment for the roll shop; and the hardware and software for the advanced Bamicon Octopus, which assists operators in stand and guide preparation and supports the entire tooling process. The commissioning of the new small bar mill line including the RSB 5.0 is scheduled for the end of 2024. Friedrich Kocks GmbH & Co KG www.kocks.de
