Abstract


Our country’s steel output has ranked first in the world for many years, iron and steel enterprises are the main pillars of the national economy, its development largely reflects the strength of a country. The development of a modern iron and steel industry is to increase the focus of the quality of steel. The sheet rolling is an important part as well as the basic link in the steel production, its precision directly effect the quality of the strip shape and the slab thickness.This subject, taking four-high reversing cold mill reforming project of Shanxi Provincial Key Laboratory of Metallurgical Equipment Design and Technology——State Key Laboratory Cultivation Base of Province-ministry Co-construct as a backing, has conducted the research to the application of the DAGG on slab thickness controlling. According to the actual situation, this thesis has proposed the Hydraulic AGC reform scheme, which changes the Electric Pressure System into Hydraulic Screw Down System and verifies the rapidity and stability of the Hydraulic System response with AMESim simulation software. Meanwhile, it has changed the Thickness Control Model into DAGC and will achieve it with step7 software. What’s more, with the reformed rolling mill and controlling system, this thesis has set up an experiment on Roll Eccentricity and steel rolling. Basing on the former experiment data, it powerfully proves that DAGC improves the precision of the thickness controlling and also proves its controlling stability.This paper by reforming the rolling mill and the control model has improved the sheet material quality, which makes DAGC extended from hot rolling to cold rolling and from tandem rolling to single stand reversing rolling. Meanwhile, this thesis provides a reference success case for the small and medium-sized rolling enterprise and scientific research institution that attempts to improve the sheet quality by reforming rolling mill with small economic cost, and offers a viable method for its product reforming, which will profit its sustainable living.
