A hybrid soft sensor for measuring hot-rolled strip temperature in the laminar cooling process

A novel acquisition approach for heat transfer coefficient during periodic cooling process

“…LCS is the main way to realize slab rapid cooling in hot rolling strips [18][19][20][21]. In this process, slab cooling is divided into two areas, one is air cooling, and the other is water cooling.…”

“…During the cooling process, the microstructure of the metal formed by the decomposition and precipitation of austenite is closely related to the temperature distribution, level and gradient [23][24]. While heat transfer boundary directly affect and determine the temperature distribution.…”

Online Cooling System and Improved Similar Self-adaptive Strategy for Hot-rolled Seamless Steel Tube

“…Therefore, few people pay attention to study online cooling temperature model for hot-rolled seamless tube. In reality, many kinds of models based on different building methods or theories had been developed and applied in hot-rolled strip or plate cooling process, [6][7][8][9][10] which can be used to build temperature model for hot-rolled seamless steel tube in cooling process. To reflect reality as much accurately as possible, statistical models are proposed in some studies, 11) which adequately consider all the influence parameters in cooling process.…”

Research and Application of Model and Control Strategies for Hot Rolled Strip Cooling Process Based on Ultra-Fast Cooling System

“…3,4) Statistical models have been developed to solve the situation that closely reflects reality as much accurately as possible. 5) And there are also many artificial intelligence algorithm models, [6][7][8][9][10] such as fuzzy control model, neural network model and instant base learning by k-NN algorithm are uti- Ultra-fast cooling technology as an effective method for control microstructure and property, is widely used in hot rolled strips. For precise control of strip temperature in cooling process, a mathematical model based on UFC is established to calculate UFC-T and CT in high pressure mode, or only CT in low pressure mode.…”
