Research On Entire Roller Intelligence Cold Strip Shape Meter And Its Industrial Applilcation

The strip shape is important qualitative index of the high-level cold-strip steel, the shape control is the core technology, the key technology, the frontier technology and the high-end technology of the cold-strip steel rolling mill. The shape meter is the"eye"for online examinating shape strip, and is the premise and the key of realizing the shape closed-loop control.The cold rolling domain's shape control aspect has been controlled by others, although the last three decades, China has made in this area some breakthrough advances in technology, but for the shape meter is always in laboratory research stage, the industrial application is almost blank. The key components of the core shape meter- Measuring Roll research, always following the foreign product , without major innovation in design. This makes the closed-loop control technology blocked by foreign companies and several major monopolies, leading to the introduction and maintenance is extremely expensive, only a small number of large domestic enterprises to introduce. But because of it is difficult in technical upgrades and process optimization follow-up, it is difficult to produce high quality strip steel product steadily, excellent mill no first-class products, customer satisfaction is generally low. At present, it si desiderate to solve the shape measurement and closed loop control in the area of the cold rolling and it is the most difficult problems.So the development of independent innovation to meet the shape meter for industrial applications is significant and critical.This paper breakthrough the international and popular technology program, successfully developed to meet industrial application of the entire roll inserts cold rolling strip-shaped instrument smart plate. Firstly, proposed an innovative concept different from international instrument popular sectional shape, the installed sensors's elastic block embedded in two rectangular tank of detection roll radial symmetry, constitute the entire roll body roll-type structure, signal sensitivity, to avoid scratch the surface of strip. Secondly, develop flow automatic spray which is set of highly integrate device ,to achieve slip ring of the self-cleaning, lubrication and cooling, significantly improved signal's stability and slip ring's service life. Thirdly, develop the device of variable packet angle calibration simulation, enhanced calibration function, to achieve the shape of dynamic precision calibration, to improve the calibration accuracy and precision. Fourthly, develop the hardware system of embedded DSP shap signal processing, to improve shape signal anti-jamming capability, reliability and real-time. Fifthly, research and develop with error compensation, the standard curve, pattern recognition, shape control function of the shape signal processing software system to enhance the shape meter Engineer. The key technologies applied not only to mill, also applies to single stand reversing mill, leveling mill, tension and leveling. Currently, the instrument has been successfully applied to the cold rolling mill in Anshan Iron and Steel 1250 mm, the overall technical indicators have reached international leading level in the same industry.The successful development of the shape meter, realized the independent innovation in the key technologies of cold rolled steel shape detection and shape control break,through the blockade and the monopoly of foreign technology. Help raise the overall level of China's cold rolling mill equipment, meet the technical requirement of producing high quality strip steel products, improve high customer satisfaction of cold-rolled strip steel products, and meet the cold rolled products demand of car plate, home appliance plate, decorative plate, coated board and other high-end market.
