CISDI to supply bar and wire-rod mills for HBIS Shijiazhuang Steel

CISDI has won two technology contracts for Shijiazhuang Steel’s relocation and upgrade projects.

The company is to be the technological lead for HBIS Shijiazhuang Steel’s premium special steel heavy bar mill, plus a quality high-speed wire-rod mill. In addition, CISDI is to package-supply the rolling equipment and hydraulic and lubrication systems.

The heavy bar mill is designed to produce 800,000-tonnes a year, made up of ø80mm-ø260mm alloy round bars, 150mm-300mm square blooms and 75mm-180mm square bars, reserved for producing flat rolled-slabs.

The high-speed wire-rod mill is designed for the annual production of 400,000-tonne coils to a size of ø5.0mm-ø28mm.

Both mills are geared to mechanical and automobile products. Applicable steel grades are quality carbon steel, alloy structural steel, pinion steel, free-cutting steel, cord steel, spring steel, bearing steel and tool steel.

Multiple CISDI-developed core technologies and equipment will be applied – the BDCD breakdown mill, NHCD short-stress path rolling mill and FSCD flying shears.
