Title (EN) A PROCESS FOR FORMING STEEL
(FR) PROCÉDÉ DE FABRICATION D'ACIER
Abstract: front page image
(EN)The invention refers to a process for forming a steel component, incorporating the steps of - providing a blank having substantially the volume of the component to be formed, - heating the blank to a semi solid state with a specific liquid fraction, - forming the blank with a forging technique to a component of near net shape dimensions, - subjecting the formed, near net shape component, to a normalization combined with a hardening, - subjecting the normalized and hardened near net shape component to machining to give the component net shape.
(FR)L'invention porte sur un procédé de fabrication d'un composant d'acier, incorporant les étapes consistant : à se procurer une ébauche ayant sensiblement le volume du composant devant être formé, à chauffer l'ébauche à un état semi-solide avec une fraction de liquide précise, à former l'ébauche avec une technique de forgeage en un composant de dimension près des cotes, à soumettre le composant près des cotes formé à une normalisation combinée à un durcissement, à soumettre le composant près des cotes normalisé et durci à un usinage pour donner au composant une dimension aux cotes.
