Abstract

An improved apparatus for steeping a surface of a metal body comprising in combination: (a) means for discharging an oxygen stream and directing it against a molten metal reaction zone on the surface of said metal body to produce a reaction thermochemistry thereon, and (b) means for producing a relative movement between the workpiece and said means for discharging oxygen, characterized by comprising: (c) means for discharging at least one non-reactive fluid stream such that it forms a laminar curtain directed to form a cover over the reaction zone and at least the rear portion of the melting puddle so that said fluid curtain forms a bag with the surface of the work piece.
