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℃.
