Zusammenfassung:	To provide a method and a device for scarfing a steel billet, which can stably scarf the surface of a steel material with a shallow depth uniformly.SOLUTION: The method and the device for scarfing a steel billet, which scarf the surface of the steel billet at a hot scarfer, satisfy the following expressions. Y≤-X+53.5 t+43.8 ...(1), X>20 ...(2), and Y>20 ...(3). In the expressions, X(mm) denotes a distance between the tip surface of a lower block of the hot scarfer and the surface of the steel billet, Y(mm) denotes a distance between the nozzle surface of an upper block of the hot scarfer and the surface of the steel billet, and t(mm) denotes a scarfing depth.SELECTED DRAWING: Figure 4 【課題】鋼材の表面を安定して溶削することができ、溶削深さを浅く、かつ、均一に溶削することが可能な鋼材の溶削方法、及び、鋼材の溶削装置を提供する。【解決手段】鋼片表面をホットスカーファーにて溶削する鋼片の溶削方法及び溶削装置であって、ホットスカーファーの下部ブロックの先端面と鋼片表面の面間距離Ｘ（ｍｍ）、ホットスカーファーの上部ブロックのノズル面と鋼片表面との面間距離Ｙ（ｍｍ）、溶削深さｔ（ｍｍ）とするとき、下記（１）（２）（３）式が満たされていることを特徴とする鋼片の溶削方法及び溶削装置を提供する。Ｙ≦－Ｘ＋５３．５ｔ＋４３．８・・・・・（１）Ｘ＞２０・・・・・（２）Ｙ＞２０・・・・・（３）【選択図】図４
