Description d\u00e9taill\u00e9e (contexte, objectifs, etc.)<\/strong>\u00a0:<\/p>

Actuellement 2 voies de production de l’acier sont utilis\u00e9es :<\/p>

-La fili\u00e8re fonte : un proc\u00e9d\u00e9 historique efficace mais fortement consommateur de charbon et g\u00e9n\u00e9rant des \u00e9missions de process. Le minerai de fer est transform\u00e9 en fonte dans le haut fourneau. Le coke de charbon sert d’agent r\u00e9ducteur et de combustible. La fonte est d\u00e9carbur\u00e9e avec de l’oxyg\u00e8ne dans le convertisseur de l’aci\u00e9rie, qui int\u00e8gre \u00e9galement entre 10 et 15% de ferrailles.<\/p>

-La fili\u00e8re \u00e9lectrique : les aci\u00e9rie \u00e9lectrique recyclent de la ferraille en acier en la chauffant \u00e0 plus de 1500\u00b0C par arc \u00e9lectrique. Avec le mix \u00e9lectrique fran\u00e7ais, le recyclage d’une tonne de ferraille permet d’\u00e9viter 75-80% des \u00e9missions.<\/p>

Saarstahl a une politique de d\u00e9carbonation en favorisant sa fili\u00e8re \u00e9lectrique et en recyclant les rails usagers provenant de ses clients.\u00a0\u00a0<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
