通过有限差分法对中厚板轧后控制冷却温度场进行模拟,得到钢板在整个控冷阶段的瞬态温度分布和温降速度分布,为均匀化冷却速度,制定合理控冷工艺提供实践指导。
The finite difference method was used to simulate the controlled cooling temperature field after the plate rolling, and the transient temperature distribution and the temperature drop velocity distribution of the steel during the whole controlled cooling stage were obtained. This could provide practical guidance for the uniform cooling rate and reasonable control of the cooling process.
