Development and application of laminar cooling simulation system for hot strip rolling
摘要
Abstract
Using Desheng 1 ISO mm hot strip mill laminar cooling system as the study object, two-dimension finite difference model was set up through the research on the system. To make the model more in line with the actual, some parameters of the model were identified and mended by the measured data. Strip temperature change curve and temperature field distribution were calculated by the model. The verification results of the model are very accordant with the measured results. Using computer simulation technology, the mathematical model and control algorithms combined laminar cooling simulation system with friendly HMI was developed in VC++ platform. The simulation system with coiling temperature prediction function, model parameter optimization function and cooling group open pre-setup function can be efficiently used to simulate cooling process, especially for the inconvenience or not working conditions in the actual production process. Comprehensive and systematic simulation analysis of various factors on the influence law of strip cooling and the change rule of the strip temperature were made. The simulation system provides a soft measurement and experimental platform for the system design, control strategy, control method optimization and product quality improvement. The simulated results are used in 1 150 mm strip line and the results completely meet online production requirements.关键词
