【摘要】 考虑板坯实际温度分布不均匀的事实,结合某钢厂的一座步进式加热炉建立了板坯加热过程的三维数学模型及其离线仿真系统。应用Sysweld有限元软件的热处理模块对加热炉内板坯温度场进行计算,并与黑匣子拖偶测试数据进行比较验证。计算结果显示在保证板坯加热质量的前提下,得到了板厚以及入炉温度与板坯所需加热时间的关系式,表明提高板坯入炉温度有利于提高加热效率,缩短板坯在加热炉内的加热时间,降低板坯氧化烧损量。更多还原

【Abstract】 A 3-D mathematical model and its off-line simulation system are built for slab heating process combined with a walking beam reheating furnace of some plant considering the uneven distribution of slabs temperature.By using heat treatment module of Sysweld finite element software,the temperature fields of slabs in the reheating furnace are calculated and validated by the black box test data.The results indicate that under the premise of quality,the relation between heating time and the thickness and the initial temperature of the slabs is obtained.It is indicated that raising the initial temperature of slabs can improve heating efficiency,shorten reheating time,and decrease energy consumption.更多还原
