CISDI’s intelligent, high-strength and optimal SPM

CISDI’s unique, optimised high-strength skin pass mill has been developed through painstaking research and constant innovation.

Its many worldwide engineering references are performing with outstanding indicators.

CISDI’s SPM for Baosteel Shanghai’s 2,050mm hot strip rolling line

Intelligent expertise:

✔         Centralised operation controls achieved via innovative, smart equipment and optimised time sequence control

✔         Integrated operation and maintenance management achieved via fault analysis and push and smart safety control

✔         Intelligent production management achieved via data collection and fusion analysis

High-strength unit:

✔         The SPM’s high rigidity enables a maximum product strength of 1,200MPa

✔         Maximum levelling force of 20,000kN improves the strip profile to Super Rating

✔         Maximum roll bending force of positive 1,000kN at one side

✔         Maximum coiling tension of 400kN with dual tongs

Optimal product quality:

✔         Innovative deep roll bending (strip’s deep drawing) tech plus dedusting function and reversing roller brushing tech plus dedusting function remarkably improve the strip surface quality

✔         Skin pass roll’s online grinding tech ensures strip’s surface quality

✔         Coil tail pre-forming tech ensures coil shape and quality

Application and patent:

CISDI has designed and supplied 25 intelligent, high-strength and optimal skin pass mills to clients around the world. Multiple patents have been awarded and there is a strong market demand.
