영문 초록

This study aims to investigate efficient techniques for mending the guide roll of the caster machine, which is one of the pieces of equipment needing frequent repair in the integrated process of ironworks. In the guide roll of the caster machine often appear abrasions, cracks, and corrosion in the surface as a result of repeated abrasion and bending compression under high temperatures. FCAW(Flux Cored Arc Welding) is chosen as the welding method, due to its relatively simple handling method and favorable expenses and working time. As for welding wire, the method uses a type of continuous roll wire which makes auto-welding possible, and also has the possibility of a hardfacing which takes advantage of the mechanical properties of the welded metal according to the chemical reaction of the flux. The overlay welding teachnique for the repair of the guide roll of the caster machine described in this paper is sure to contribute to the improvement of the quality of steel products and productivity, as well as the reduction of repair expenses by overlay welding of guide rolls in the future.
