Abstract

The invention discloses a heat treatment furnace heating model calculation method based on a graphic processing unit (GPU). The method includes the following steps: building an internal heat conduction mathematical model of a heat treatment object which is a steel blank or a steel roll, dividing the heat treatment object through a grid, adopting a finite difference method to conduct discretization on the heat conduction mathematical model, mapping the generated grid on a GPU thread, utilizing the discrete heat conduction mathematical model to map the generated grid on the GPU thread to obtain a calculation result. By means of the method, the heating model calculation time can be reduced greatly, and model system response speed is increased.

Description

technical field [0001] The invention relates to the field of heat treatment, in particular to a GPU-based calculation method for a heating model of a heat treatment furnace. Background technique [0002] In the field of metallurgical production process control, the heat conduction model is a widely used mathematical model. The traditional heat conduction mathematical model algorithm is implemented using the finite difference method, and the application of real-time temperature forecast and model optimization calculation is realized through the high-performance CPU of the server. At present, the calculation method of the heating model of the heat treatment furnace is to use the finite difference method to iteratively calculate the temperature distribution of the steel coil, and obtain the optimal annealing set value through the optimization calculation. This calculation method uses the CPU for calculation, and the calculated coil section The grid is divided first, and then t...
