| 摘 要： | 建立了三段步进梁式加热炉内加热的板坯物理模型和数学模型.用全隐式有限差分法对数学模型进行了离散化,同时运用软件工程的理论,编制了加热炉内板坯温度场计算软件.计算结果表明,在保证板坯加热质量的前提下,提高加热炉预热段温度、板坯入炉温度和炉气黑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和延长炉子寿命.

| Abstract: | A physical and mathematical model for slabs heated in a 3-zone walking beam type of re-heating furnace was established. The finite difference method was used for discretization of the physical and mathematical model and a computational software was developed according to the software engineering theory. The results indicate that raising the temperature of reheating zone, the slab initial temperature and the emissivity of furnace gas can improve slab heating efficiency while guaranteeing the final quality of slabs. Reduction in heating zone temperature can decrease energy consumption and prolong the furnace campaign life. |
