NO SHOW: Elimination of Surface Cracks in Low-Carbon Peritectic Grades by Optimizing the Casting Parameters

Surface cracks forms during the continuous casting because of the thermal gradients through the solidifying shell and the stress generation resulting from differential expansion or contraction. It is one of the serious quality problem because the cracks oxidize and give rise to oxide-rich seams in the rolled product. During solidification, low carbon steels that are in peritectic range are prone to surface cracks due to the volume changes in the peritectic reaction. The present work discusses the optimization of the parameters such as primary, secondary cooling, casting powder and casting speed that contributes to the surface crack.
