建立了三段步进梁式加热炉板坯加热过程数学模型,用全隐式有限差分法对数学模型进行离散化,开发了板坯温度场计算模型.采用该模型重点研究了板坯宽度对板坯中心温度变化过程的影响规律.研究结果表明,对于厚度为200 mm的板坯,当板坯宽度大于600 mm时,板坯中心温度变化过程与板坯宽度无关.以此为根据,优化了板坯加热工艺,达到了提高生产效率并节能减排的目的.

A mathematical model for slabs heated in a 3-zone walking beam type of reheating furnace was established. The finite difference method was used for the discretion of the mathematical model and a com-putational software was developed. The influence of the slab's width on the change of the slab's tempera-ture was studied. It was founded that, to the 200 mm thick slab, when the width is above 600 mm, the slab's width has no influence on the slab's center point temperature. According to the result, the slab's reheating process was optimized, which improved the productivity and saved the energy.
