摘　　要：以U71Mn钢为例,通过观察在加热和轧制过程中的钢坯脱碳层的变化,研究加热时间、保护涂料和轧制形变率对重轨钢坯脱碳和氧化的影响。通过对实验数据进行回归分析,给出坯料加热脱碳及轧制脱碳的预报模型。Taking U71Mn steel as an example, the effect of heating time, protective coating and rolling deformation rate on decarburization and oxidation of the heavy rail slab has been studied by observing the changes in the slab's decarburized layer in the course of heating and rolling. And the slab's decarburization prediction models in heating and rolling have been proposed through regression analysis of the experimentsal data.
