Abstract

PURPOSE:To increase the strength of the weld zone, in the case of continuous rolling, where the forward steel material and the following steel material is welded, between the hot roughing rolling and the hot finishing rolling of the steel material, by spreading oxide, etc., of a specified metal over the faving surface of both steel materials, and further, by taking both steel materials using the needle type material.
