A world-class dual high-speed bar rolling line is now operating successfully at Baowu Chongqing Steel.

Built by CISDI on an EPC basis, the line’s projected production capacity is 1.40 million tonnes a year and its main product specification ranges from 8 to 22 millimetres in diameter.

It operates with state-of-the-art tech, equipment, quality and management levels, producing bars for high-strength buildings. CISDI has designed, manufactured and integrated the line’s core process, equipment and automation.

A number of CISDI’s intelligent, information technologies have been applied:

ü  Continuous casting and direct hot charge rolling

ü  Single pass rolling

ü  NHCD short stress path rolling mill

ü  CDMC super-heavy-duty high-speed modular mill.
