The two companies already look back on a successful partnership, as this is the third Kocks Reducing and Sizing Block (RSB) installation for Huaigang, following previous projects in 2010 and 2019. A fourth installation is in the process of being set up. With the installation of this biggest Kocks block in Huaigang's existing bar mill line, the Chinese SBQ producer is extending its capacity for the production of high-quality special steel for various industries. The advanced Kocks 3-roll technology of the “RSB” will greatly benefit Huaigang Special Steel's production capabilities and improve the overall efficiency of its operations. In addition to providing the “RSB 500++/4”, Kocks also supplied equipment for the roll shop and proprietary software solutions. Despite the challenges posed by the ongoing pandemic, the project team was able to successfully execute the installation in a timely and efficient manner.
