Abstract Scope Different steel grades are subjected to surface cracking on the route from continuous casting to hot rolling. One of the causes is the local formation of hard structures and/or fine precipitates after casting depending on the slab handling and position in a pile, which is believed to influence its cracking risk. To evaluate the influence of the slab position on the cooling rate, a FEM model was built to calculate different cooling profiles in short and high piles using Abaqus CAE. The effect of different transport routes on phase transformations and sizes of precipitates for two steel grades (A: 0.08% C, 0.12% Ti and 0.05% Nb; B: 0.08% C and 0.001% Ti) were investigated using TM simulator DIL805A, mechanical testing, MatCalc software and means of LOM and SEM analysis. Critical conditions leading to bainitic structure and fine precipitates instead of a homogenous ferrite/pearlite matrix and larger precipitates could be defined.
