The investment highlights Chengde Jianlong's dedication to the continuous integration of advanced technology. The project follows a previous successful finishing block installation with Kocks a few years ago.

In 2017, Chengde Jianlong modernized its small bar mill SBQ line with a Kocks “RSB 370++/4” in 5.0 design, which resulted in a significant improvement in product quality and mill output. For the current greenfield project, the steel producer again consequently relies on Kocks' proven portfolio for producing high-quality specialty steels. Chengde Jianlong Iron+Steel is a leading Chinese steel producer based in Chengde and part of the Jianlong Group. The company is renowned for its extensive production of high-quality steel and its significant role in China's steel industry.

In the newly built 1,000,000t/a rolling mill for larger dimensions, a “RSB 500++/4” in Star Drive design has now been successfully commissioned. Straight after rolling the first bar, the four-stand finishing block started regular production. The “RSB 500++” rolls high-quality, straight bars with a diameter of 60mm to 160mm onto the cooling bed.

This biggest reducing and sizing block comes in the advanced “RSB” design. The further scope of supply included the remote control for stands and guides, which allows operational parameters to be adjusted from the control stand. In addition to the roll shop equipment, Kocks installed the „Bamicon” Octopus software and hardware features that assist operators in the stand and guide preparation and support the entire tooling process in the roll shop.
