Description

Technical field [0001] The invention belongs to the technical field of simulation and automatic control of the cooling process of a steel plate after rolling, and specifically relates to a steel plate cooling control simulation system and method. Background technique [0002] The online accelerated cooling process of rolled high-temperature steel plates has been widely used in the production process of thick plates with high strength, high toughness and good weldability. The controlled cooling of the steel plate is through the control of the structure of the steel plate, which greatly reduces the investment of the alloy and saves the post-processing procedures, so as to achieve the purpose of saving costs and improving economic benefits. [0003] With the development of controlled rolling and controlled cooling (TMCP) technology, the speed requirements for cooling control value setting are getting higher and higher, whether the speed calculated by the physical-mathematical model ...

Problems solved by technology

However, the improvement of any of the above needs to have a comprehensive grasp of the upper and lower computer systems and a full understanding of the interface. Large process improvements will also involve changes in the system structure, which will bring risks to the commissioning of the production line , may even bring some loss

[0004] Although there are many papers published on laminar flow cooling simulation, they are basically based on the research of specific algorithms or a certain process. The simulation software package does not have the exchange of signals between sensors and controllers, and they are all simulation results obtained under many assumptions. , can only evaluate the algorithm to a certain extent, and it is difficult to realize the engineering research of general control technology
