sowie nach Art, Menge und Zustand der Formmasse der Giessform. Diese die Wärmebilanz beeinflussenden Grössen können für gegebene Werkstücke und Verhältnisse festgelegt bzw. vorausbestimmt werden.
Bei der richtigen Wärmebilanz wird die durch das Eing1lsskanalsystem in einer Mehrzahl senkrecht zur Lagersehalenachse dem Hohlmantel zwischen Rotgussschale und innerer Giessformwandung plötzlich

mantel der Lagersehale bei ihrer Berührung mit der dabei als Kernstück dienenden Rotsussschale an der Berührungsoberfläche abgeschreckt und alsdann durch Wärmeübertragung aus der Stahlmasse durch die dabei gebildete kühlere Schutzschicht derselben hindurch der Rotgusskernmantel zum Schmelzen gebracht, wobei dann ohne Vermischung von Rotguss-und Stahlmassen miteinander an dieser Berührungs- sehieht unter dem durch die Klammerwirkung des erstarrenden Inhalts des Eingusskanalsystems erhöhten Schrumpf- bzw.
Schwindungsdruck des erstarrenden Armierungsstahlmantels die erstrebte, innige und gleichmässige Schweissverbindung zwischen den beiden Metallteilen erfolgt und durch die die Erstarrung der Metallmassen regelnden und das Herauspressen der flüssigen Rotgussmasse unter Druckentlastung verhindernden Kühlmassnahmen bzw. Kühleinriehtungen gesichert wird.
Die Zeichnung zeigt beispielsweise eine nach dem Verfahren gegossene armierte Lagerschale i

Die Angüsse k sind entstanden durch die Ausfüllung des Eingusskanalsystems beim Eingiessen des Stahls in die Form.
Beim Erstarren des Inhalts des Eineusskanalsystenis entsteht die oben näher beschriebene Klammer- wirkung.

as well as the type, quantity and condition of the molding compound of the casting mold. These parameters, which influence the heat balance, can be defined or predetermined for given workpieces and conditions.
With the correct heat balance, the hollow casing between the gunmetal shell and the inner mold wall suddenly becomes apparent through the inlet channel system in a plurality perpendicular to the bearing shell axis
EMI2.2
The shell of the storage shell is quenched when it comes into contact with the Rotsuss shell, which serves as the core piece, on the contact surface and then melts the gunmetal core shell by heat transfer from the steel mass through the cooler protective layer formed, whereby the gunmetal core jacket then melts without mixing the gunmetal and steel masses with one another The contact point under the increased shrinkage or shrinkage due to the clamping effect of the solidifying contents of the sprue system.
Shrinkage pressure of the solidifying reinforcing steel jacket the desired, intimate and uniform welded connection between the two metal parts takes place and through which cooling measures or cooling devices that regulate the solidification of the metal masses and prevent the pressing out of the liquid gunmetal mass under pressure relief are secured.
The drawing shows, for example, a reinforced bearing shell i cast according to the method
EMI2.3
The sprues k were created by filling the sprue system when pouring the steel into the mold.
When the contents of the inlet duct system solidify, the clamping effect described in more detail above arises.
