Research On Wide Cross-cutting Line Control System

This topic comes from a medium-sized iron and Steel Group hot-rolled plant in China, this paper introduces the basic situation of the hot rolling mill of hot cross cutting line of German SMS-DEMAG. With the terminal customers of the production line product approval, the cross cut production capacity can not meet the actual production requirements, production to improve the efficiency of the problem, to solve this problem, not only can improve the production capacity, can also improve product competitiveness in the market. The hot rolling mill based o. The hot rolling mill based on the original production line to develop with independent intellectual property rights of the new cross cutting line. This topic will be the automation of hot cross cutting research. The tangent is the goal of plate roll forming into a certain size, so the research on the technology of steel rolls uncoiling is essential and important.Stability of uncoiling machine in the production process is an important factor to evaluate the unit stability. According to the given production features wide traverse calculation method, calculation method of tension compensation principle and the volume diameter.Sizing accuracy is an important factor of crosscut set product quality evaluation. To analyze the motion law of crosscut set flying shear, establish mathematical model, to improve the cutting precision flying shear for the purpose of, respectively, the current loop, speed loop, position loop regulator. The use of fuzzy control to the control parameters of the traditional PID control is modified, optimized the position control model of flying shear, which has good dynamic performance and stability.According to the technological characteristics of cross-cutting line to track across the region, and divide the trace level. To determine the overall program, all tracking function of the horizontal tangent track design, data flow, using binary and hexadecimal sixteen material status description method of material tracking process management. At the same time, on the basis of the above theory to design horizontal tangent line tracking system, and gives the program flow. Hope can fundamentally solve the problem of improving product capacity.
