VERFAHREN UND VORRICHTUNG ZUR WAERMEBEHANDLUNG VON OBERFLAECHEN VON WERKSTUECKEN AUS STAHL

摘要

A first high energy beam is projected against a first flank surface of a substantially V-shaped steel surface, and simultaneously thereto a second a high energy beam is projected against a second flank surface of the V-shaped surface. The high energy beams may be electron beams or laser beams and may be provided from a single source or separate sources. The separate high energy beams are projected against the respective flank surfaces at angles as close as possible to vertical thereto, thereby subjecting the flank surfaces to a heat treatment to form a hardened layer.
