Patent-Anspruch:Patent claim: Verfahren zum Gießen von Verbundblöcken oder sonstigen Gußstücken ,durch Übereinandergießen von zwei oder mehr verschiedenen Metallen oder Metalllegierungen in einer eisernen Gußform nach Patent 277292 zur Herstellung von für Eisenbahnschienen u. dgl. bestimmtenVerbundblöcken, dadurch gekennzeichnet, daß die z. B. für Eisenbahnschienen o. dgl. bestimmten verschieden harten Stahlsorten nicht in zwei oder mehr verschiedenen Frischöfen hergestellt werden, sondern daß man nur aus eiη em Frischofen in der Weise arbeitet, daß in diesem Ofen der Frischprozeß bis zur vollständigen Entkohlung sowie Entfernung aller schädlichen Fremdkörper durchgeführt wird, daß man hierauf den Metallinhalt des Frischofens in zwei bzw. mehr Gießpfannen abgießt, und dann in jede dieser Pfannen die für die gewünschte Zusammensetzung der betreffenden Stahlschicht erforderlichen Zusatzstoffe (Kohle, Mangan, Silizium u. dgl.) zugegeben werden.Process for casting composite blocks or other castings by overmolding of two or more different metals or metal alloys in an iron mold according to patent 277292 for the production of railroad tracks and the like certain composite blocks, characterized in that the z. B. for railroad tracks or the like. Certain types of steel of different hardness are not produced in two or more different fresh furnaces, but that you can only come from a fresh oven works in such a way that in this oven the freshening process is complete Decarburization as well as removal of all harmful foreign bodies is carried out that one on this the metal content of the fresh furnace is poured into two or more ladles, and then into each of these pans the one for the desired composition the additives required for the steel layer concerned (coal, manganese, Silicon and the like) can be added.
