<p>A steel-slab-use hot scarfer constituted by arranging side by side a plurality of scarfer units each comprising an upper block and a lower block provided with fuel gas jetting ports, an oxygen passage provided between the upper block and the lower block, and shoes mounted on the lower block, wherein the positions of between-shoe contact surfaces formed between adjacent shoes are deviated sideways from the positions of between-lower-block contact surfaces formed between adjacent lower blocks to thereby prevent oxygen passing through oxygen passages from leaking from between the contact surfaces, whereby the deterioration of the surface profile caused by slag occurrence due to abnormal combustion can be prevented.</p> |
