抄録

To clarify the mechanism of internal cracking in continuous casting, a series of tensile tests of cylindrical ingot with liquid core and internal cracking tests by intentional misalignment in continuous caster were carried out. By analysing the above experimental results with strain accumulation model, it wad found that internal cracking occurs and grows in the range where the total amount of strain given between ZST and ZDT exceeds the critical strain. Severe longer internal cracks which often generates in continuously cast strand is estimated to be caused with the development of solidification. To prevent internal cracking, not only suppression of each incremental strain, but the determination of casting condition and roll-lavout to suppress total amount of accumulated strain smaller, considering the range between ZST and ZDT is significant.
