Description

Verfahren zum Herstellen nicht harter Gußstücke in gekühlten Schleudergußkokillen Die Erfindung betrifft eine besonders vorteilhafte und :einfache Weiterentwicklung des durch das Patent 633 oIO geschützten Verfahrens zur Herstellung nicht harter Gußstücke in gekühlten Schleudergußkokillen, gemäß welchem die Kokilleninnenwand an der Stelle, auf die jeweils das flüssige Metall aufgebracht wird, eine derart örtlich begrenzte Erwärmung :erfährt, daß die Bildung harter Außenschichten verhindert oder zumindest stark herabgemindert wird.Process for the production of non-hard castings in cooled centrifugal casting molds The invention relates to a particularly advantageous and simple further development of the process for the production of non-hard ones, protected by the patent 633 oIO Castings in cooled centrifugal casting molds, according to which the mold inner wall at the point to which the liquid metal is applied, one such Localized heating: learns that prevents the formation of hard outer layers or at least greatly reduced.

Gemäß der Erfindung erfolgt die örtlich begrenzte Erwärmung der Kokille durch die Strahlungswärme eines elektrisch beheizten Widerstandes. Dieser elektrisch beheizte Widerstand kann bei Benutzung einer Bri@ederinne zum Gießen zweckmäßig unmittelbar an der Briederinne befestigt sein, an welcher auch die Stromzuführungsleitung angebracht sein kann. lntolge der außerordehtli:ch hohen Temperaturen, die mit elektrisch beheizten Widerständen hervorgerufen werden können, wird es durch den Erfindungsgegenstand erreicht, daß eine sehr kräftige örtliche Erwärmung der Kokille stattfindet, so daß der auf diese verhältnismäßig hocherwärmten Stellen der Kokillenwandung auftreffende Gießstrahl keine allzu schroffe Abschreckung erfährt und mithin der Entstehung von Weißeisenschichten dadurch in äußerst vorteilhafter Weise vorgebeugt ist.According to the invention, the localized heating of the mold takes place by the radiant heat of an electrically heated resistor. This electric heated resistance can be useful when using a Bri @ ederinne for pouring be attached directly to the Briederinne, on which also the power supply line may be appropriate. As a result of the extraordinarily high temperatures associated with electrical heated resistors can be caused by the subject matter of the invention achieved that a very strong local heating of the mold takes place, so that the impinging on these relatively highly heated points of the mold wall Pouring stream is not deterred too abruptly and therefore the development of White iron layers is thereby prevented in an extremely advantageous manner.
