摘要基于连铸、输送、加热过程大板坯的传热研究，针对E36铸坯的组织演变，系统研究了不同热履历对E36铸坯组织演变的影响，为优化界面技术提供了依据。结果表明，铸坯以不同输送方式冷至625℃以下再加热后的开轧组织没有显著差异，铸坯是否经过奥氏体-铁素体-奥氏体相变过程是影响开轧组织的主要因素。铸坯横断面不同位置的组织演变过程不尽相同，若采用低温区装炉，应保证铸坯横断面中心温度在625℃以下，若采用高温区热装，应将铸坯角部温度控制在805℃以上。

Abstract：Based on study for heat transfer of slab in process of continuous casting-conveying-heating, as for the micro-structural evolution of E36 slab, the effect of different thermal history for micro-structural evolution was investigated to provide the reference for the improvement of interface-technique. Their start rolling microstructure is no significant difference after heating when slab conveyed by different way and then cooled down to the temperature below 625℃. γ-α-γ phase transformation is one of the main factors affecting the start rolling microstructure. The micro-structural evolutions of slab cross section at different positions are not the same. If low charging temperature is adopted, the temperature of central of slab cross section should be below 625℃. Whereas, the temperature of slab corner should be above 805℃.
