In order to control surface cracks in beam blank via continuous casting process,a thermo-mechanical coupling model considering the taper and air gap was established to compute the temperature and stress in the mold based on stress genetic characteristics of the slab shell and multiple load step way.From the modeling resultthe location where longitudinal surface cracks easily occurred is on the fillet at the central part of the mould.This finding will help to control longitudinal surface cracks initiation and growth.
