An improved BP neural network model was presented by modifying the learning algorithm of the traditional BP neural network, based on the Levenberg-Marquardt algorithm, and was applied to the breakout prediction system in the continuous casting process. The results showed that the accuracy rate of the model for the temperature pattern of sticking breakout was 96.43%, and the quote rate was 100%, that...
The process of solidification of continuous casting of thin slab on compact strip production (CSP) was simulated by finite element method (FEM) and two-dimensional cutting slice method. Simulated results of solidification and heat transfer of the slab were gotten. The temperature distribution of the cooling process on the thin casting slab is agreed with the actual online production. Influence of...
According to actual circumstance of Han Iron and Steel Company CSP, a three-dimensional mathematical model of fluid flow in the mould has been developed. The process of fluid flow is simulated in aid of fluid simulation software FLUENT, when we use two kinds of SEN separately in cast. The fluid flow in the mould is simulated at the difference of technical parameters (flow-guiding slot angle and submerge...
A three-dimensional heat transfer model was developed to simulate the temperature distribution of the cooling copper mould used in the thin slab continuous casting process. Temperature field of the copper plate of the funneled mould was calculated by finite element method (FEM). It was confirmed that the simulation results are in agree with the experiments and actual online production. Influences...
