CISDI’s automation upgrades bring massive results for two Chinese rolling lines

Thanks to CISDI’s optimisations for automation systems, two Chinese hot rolling lines have made massive increases in daily output.

Each line features a nominal roll barrel length of 1.78 metres.

One of the lines, which is located in China’s north, had its automation control system upgraded after over ten years of operation. It resulted in a remarkable increase in rolling rhythm and a much-improved coil quality.

CISDI carried out the front-end preparations and were onsite for critical rebuilds and commissioning assistance.

A daily record of 852 coils and a daily production exceeding 19,500 tonnes has been achieved. The line’s daily average output has risen by 34.6 per cent.

Meanwhile in southern China, optimisation of a hot rolling line has resulted in a huge increase in production and quality.

Working remotely with the client’s onsite team, CISDI solved acute problems which had been occurring at the three-year-old line.

Optimisations boosted the rolling rhythm, enabling the line to produce 49 coils per hour.

Its daily maximum output is now 876 coils, amounting to a minimum daily production of 25,440 tonnes - a record for China’s wide strip rolling sector.

CISDI’s talent pool of hot-rolling specialists and its advanced toolkit of automation and control models is bringing about major transformation.

Its safe, fast remote ops management and digital hot rolling systems are playing a unique role in providing tailor-made solutions.

With a vast amount of engineering and package supply experience, CISDI is empowering China’s hot rolling with IT-based, digital production.
