Localized reinforcement of structural steel sheets by localized heating and cooling to form tempered spaced strips at the localized points

A method for the localized reinforcement of a steel based structural sheet consists of heating one or more localized zones of the sheet so that the steel thus heated may be partially austenitized, then the zone(s) are subjected to gas cooling to transform the steel thus heated to a tempered structur...

Zusammenfassung:	A method for the localized reinforcement of a steel based structural sheet consists of heating one or more localized zones of the sheet so that the steel thus heated may be partially austenitized, then the zone(s) are subjected to gas cooling to transform the steel thus heated to a tempered structure. An Independent claim is also included for a device for locally reinforcing a structural steel sheet. L'invention concerne un procédé de renforcement localisé d'une tôle de structure à base d'acier, caractérisé en ce qu'on chauffe une ou plusieurs zones localisées de la tôle, de façon à ce que l'acier ainsi chauffé ne soit que partiellement austénitisé, puis qu'on soumet la ou les zones localisées chauffées à un refroidissement à l'aide d'un gaz, de façon à transformer en structure de trempe l'acier ainsi chauffé.
