Jiyuan orders RSB® 500++/4 for new big bar mill line

The Chinese special steel producer Jiyuan Iron & Steel has placed an order with KOCKS for a Reducing & Sizing Block RSB® 500++/4. The equipment will be installed in a new big bar mill line. With this already being the fourth RSB® for Jiyuan, the project underlines the close and trusted relationship between the two companies. At the same time, it marks the 50th RSB® to be integrated in China, illustrating the strategic relevance of KOCKS’ 3-roll technology in SBQ mills.

The new KOCKS RSB® 500++/4 will be integrated as the finishing block in a new big bar mill line, enabling Jiyuan to roll large bar sizes from 50.00 to 160.00 mm with highest dimensional accuracy, tight tolerances, and operational reliability. This second RSB® 500++/4 for Jiyuan represents a strategic move to further strengthen the company’s position. As the investment will increase flexibility in meeting demanding customer requirements it supports Jiyuan’s ambition to lead the Chinese market for large-size SBQ products.

In addition to the RSB® 500++/4, the scope of supply includes the Remote Control for automatic stand and guide adjustments and BAMICON Octopus as workflow-oriented solution for roll shop operations. Seamlessly connected to the RSB® and higher-level systems, it forms a solution to contribute to consistent setup processes, exact control of rolling results, and highest flexibility across the complete size range.

With the order placement, the project has entered the execution phase. KOCKS will support Jiyuan as a technology partner with proven equipment, process expertise, and service competence through commissioning, which is scheduled for mid-2027.
