“…Model accuracy is the basic condition of mill setup accuracy. Also model learning methods are used to improve the model accuracy with actual rolling data [7]. The using purpose of the pilot mill is different with the producing mill, pilot mill is used for new steel grade development and new process research, but the producing mill is used for stable product manufacturing.…”

Pilot hot rolling mill is developed with perfect measuring devices and automation system. The hot rolling experimental studies of the plate and strip can be done on this mill. Automation system for this pilot mill is composed with Basic Automation System (BAS), Process Control System (PCS) and Human Machine Interface system (HMI). PC server is used as the PCS hardware, and Microsoft software is used as the operation system and developing software. With the coordination of the functions such as date communication, process tracking, data management, and model calculation, the PCS software function is realized. The effect on the model calculation accuracy with the pilot mill using condition was analyzed. This pilot hot rolling mill gets a lot of application. The practical application shows that the PCS’s setup has a high precision.

“…It is urgent to solve the problem of plate camber in the plate rolling process due to large number of influence factors and complicated relationship between the influence factor and plate camber. The study on plate camber was first developed in Japan, and a lot of breakthroughs have been made in the fields of research and applications [1][2][3][4][5][6][7], and it grows fast in China [8][9][10][11][12]. The current investigation concentrates on the development of detection means and control techniques.…”

During the past two decades, progress has been achieved for the plate production in various areas, from the level of equipment to the processing techniques, and from the product size to the quality of the products as well. However, plate camber which may affect the stability of rolling has been one of those thorny problems due to the complexity and variation of plate camber. Analysis of the factors which may lead to plate camber, including slab wedge, temperature uniformity across the plate width, side-guide alignment, stiffness difference at two sides of the mill and the inclination of the roll gap, the features of the plate camber have been studied. Using measurement and quantitative analysis of plate camber, process data analysis of the plate, equipment monitoring and operation adjustment, a systematical diagnostic strategy of plate camber has been carried out. It has shown that the developed diagnostic strategy is satisfactory in one domestic Plate Mill.

According to the characteristic of plate rolling process and the on-line applications, the non-homogeneous wear and thermal expansion of rollers, the elastic recovery and thermal expansion of work pieces, the variation of oil film thickness and the zero point deviation, which influence the precision of gap setting model, are analyzed. Based on the results of analysis, a high-precision gap setting model is proposed, and a zero point correction method is developed, in order to avoid overshoot, damp coefficient, which is affected by the thickness of work piece and zero point deviation are considered, is introduced. On-line applications indicate that the gap setting model improves the precision of gap setting and laid a good foundation of further improvement of thickness accuracy.
