Abstract

Continuously cast billet sections containing halfway cracks and in-plant, hot rolled rod from the same heat have been examined for open defects. It was found that significant open defects were present in the steel after a reduction of 4:1. A direct correlation between initial crack dimensions and open defects after a given reduction could not be made as the initial crack configuration varied appreciably along the billet length. Laborav scale, hot rolling of small continuously cast billet sections containing a known halfway crack configuration showed hot reductions greater than 6:1 are necessary to effectively close halfway cracks. This is applicable for cracks oriented both parallel and prependicular to the rolling plane. Small pores and lines of inclusions present in material reduced 10:1 did not affect the low temperature fracture stress of the steel.
