摘要： 采用辐射网络法推导了坯侧热流的有关表达式,分析了布料间距对加热时间以及炉子生产率的影响.在导出相对生产率解析表达式的基础上,采用求相对生产率极值的方法确定炉内坯料最佳间距,方法简单,便于实际应用.与前人的研究相比,本研究解除了料坯表面为黑体表面的假定,所以,导出的表达式更具一般意义.本研究成果对于钢坯或有色金属坯的步进梁式加热炉布料优化操作有参考价值.

Abstract: The reasonable billet space in walking beam furnace is of great significance to improve the productivity of the furnace. The related expressions of billet side heat flux were derived by using a radiation network, and the effect of billet space on heat-up time and furnace productivity were analyzed. What's more, the optimum space between billets was gotten using the extremum of relative productivity computed expression, which had been derived. Compared with the references, this study gets rid of the assume that the billet surface is bold and the expressions worked out are more general used, which has the important reference value to optimize the arrangement of billet and non-ferrous metal billet in the walking beam furnace.
