S&T: Dual-module reducing tech rolls to success

CISDI’s dual-module reducing mill has achieved its rolling targets during commissioning at the Xinjiang steel plant operated by Xinxing Ductile Iron Pipe Co.

Wire rod with a diameter of 10 millimetres can now be rolled at a speed of 62 metres a second - a dramatic increase on 55 metres a second - thanks to the mill.

The entire rolling line’s speed and output will eventually be improved.

Manufacture of the equipment for Xinxing Ductile was carried out during challenges posed by the Covid-19 pandemic. Swift rearrangements to working patterns were made and all equipment was delivered to site on schedule.

The technical services team - made up of process, equipment, electric and automation and hydraulic engineers - were on site day and night and completed all the specifications commissioning on schedule.

Startup of the mill resulted in immediate ramp-up. Production capacity has increased in output by the following ratios: specification Φ8.0mm by 12.1%, Φ12.0mm by 20%, Φ6.0mm by 15%, Φ10.0mm by 12%.

CISDI began development of its dual-module reducing mill in 2015. Continuous innovation and optimisations created an independently-driven, green, low-consumption and modularised reducing mill.

It is now used widely in China by companies who previously had no option but to import reducing mills for their high-speed bar and wire-rod rolling lines.

“We greatly appreciate the specialism and craftsmanship demonstrated by CISDI’s team throughout the design, installation and commissioning of our rolling line,” Xinxing Ductile Iron Pipe Co. said in a letter of thanks to CISDI.

“The high-quality equipment has boosted our production capacity quickly and successfully.”
