Abstract

PURPOSE: To provide a method for cutting away the defective part of a steel material such as a slab, a bloom and the like obtained by the hot rolling step, comprising obtaining estimated value of the defective part by a statistical method, and determining the cutting reference dimension by deducting cutting allowance from the estimated value thereby cutting the defective part at good yield.
