Development of casting practices to minimise transverse cracking in microalloyed steels*
Développement de méthodes de coulée afin de réduire les criques transversales dans les aciers microalliés
Extensive investigations have been carried out to develop casting practices to minimise transverse cracking. Cracking mechanisms were reviewed and on-plant and laboratory studies were made of the effects of process and engineering factors and steel chemistry. Major parameters identified include casting powder, mould heat transfer, oscillation and level control, alignment and straightening strains, secondary cooling to avoid the ductility trough, and steel composition.
Trials were also carried out using large mould corner chamfers to reduce transverse corner cracking.
