Two high-speed wire-rod rolling lines at Yonggang in China’s Jiangsu Province are to be upgraded with CISDI’s unique, patented short-stress path rolling mill technology.

All producing and standby roughing mills, intermediate mills and auxiliaries will be manufactured and delivered by CISDI Equipment Co, which is based in Chongqing, China.

The order will be the 120th for CISDI. This unique mill has won more than 10 patents in China.

A core product for the company, it features a high standard of rigidity, precision and stability and its standard equipment can be manufactured to 13 specifications, ranging from NHCD300 to 1000.

A full gamut of product specifications has been applied around the world and the mill is showcasing world-class performance levels for special steels rolling.

Winning the contract was a challenging process. During the bid, pandemic lockdowns in China meant communications between CISDI’s team and Yonggang could only be carried out by video link or phone. But combined with its long list of references and strong reputation, the team managed to submit what the client considered to be outstanding proposals.

Yonggang’s new high-speed wire-rod rolling lines will produce special steels, with a projected annual production capacity of 1.15 million tonnes.

Products will be high-quality wire rods in a diameter range of 5.0 to 28.0 millimetres. A space at the site has been reserved for the future construction of heavy coils.
