Abstract


The continuous annealing line is an important part of the production of cold-rolled strip steel, it has a number of advantages of short process, high yield, good quality products, the production of high surface quality requirements and higher intensity strip (such as car plates) indispensable equipment. The strip has the right tension is one of the important conditions for strip high-speed operation and prevent the strip deviation and thermal buckling good strip shape. Due to the complex nature of the process of the metallurgical industry, people using the simulation system to investigate the dynamic characteristics of a variety of complex objects in depth, and troubleshooting and a variety of advanced control technology experiments. In this paper, the analysis of the mechanism of tension, the the Continuous Annealing area strip tension dynamic model, including dynamic mechanistic models and state-space expression. On this basis, the development of the model simulation program and control simulation program the strip tension closed loop control simulation software. Specific work is divided into the following: established dynamic mechanistic models and state-space expression model uncoiler strip tension developed model simulation program, the establishment of the simulation program and model simulation program composed of uncoiler tension control The tension of the closed-loop control simulation software, and simulation experiments and results analysis. Looper and metallurgical industry production line, the the annealing unit's entry looper drive roller, trolley and hoist Vertical Looper, therefore, the the looper tension existing model does not apply to even retire unit entry looper. Annealing unit entry looper area strip tension as the research object, first establish a mechanistic model of the strip tension control simulation program, and then according to the scene of the control system, developed and established by the the the tension model simulation program and control simulation the the the entry looper area strip program consisting closed-loop tension control simulation software, and simulation and results analysis. 3. Temperature variable is introduced into the furnace of tension model furnace strip tension dynamic mechanistic models and state-space expression model developed model simulation program, the establishment of a simulation program by tension control and model simulation program the composition of the furnace closed-loop tension control simulation software, and analysis of simulation experiments and results. 4. Establish the expression model of the dynamic mechanism of the model and the state space of the tension roller strip tension developed model simulation program was established to control the simulation program and model simulation program composed by tension tension roller tension closed-loop control simulation software, and simulation and analysis of results. 5. Furnace strip tension control system of semi-physical simulation system development.
