METHOD FOR PARTIALLY GRINDING SURFACE FLAWS OF BLOOM AND SLAB WHILE BEING HOT,AND APPARATUS FOR CARRYING OUT THE SAME

摘要

A method for partially grinding surface flaws of hot steel slabs including bloom, wherein the hot bloom immediately after being hot-rolled is maintained in the state most suitable for detecting surface flaws therein in the rolling line from a rolling mill to a cooling zone. The surface flaws are detected and the thus detected surface flaws are removed by grinding, while the bloom is hot.
