Study on Control Technology of Transverse Corner Cracks on CC Slab for Automobile Frame Steel Plate

Abstract:

Article Preview

There were serious transverse corner cracks on continuous casting slab of automobile frame steel plate in Panzhihua Steel before, and study on the control of transverse corner cracks had been carried out. Some effective countermeasures are put forward, such as the optimization of ratio of heat flux density on narrow side and broad side of casting slab (RHFD) and mold powder, as well as the stabilization of casting speed and working condition of caster. Industrial test shows that the transverse corner cracks on continuous casting slab have been significantly reduced, and the lines and peeling defects on hot rolled sheet have been eliminated due to the transverse corner cracks.
