Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bei gegossenen Formkästen werden beim Losklopfen der Form insbesondere die Flanschen vielfach beschädigt oder die Kästen springen entzwei. Gegenstand der Erfindung ist, Formkästen aus Siemens-Martin-Stahl auszuschmieden und zu walzen. Bei solchen sind obige Mängel ausgeschlossen und ist die Lebensdauer bedeutend länger. Auch kommt bei diesem Verfahren die schnellere Beschaffungsmöglichkeit sehr zustatten, da man an einem Tage auf einem eigens hierzu geschaffenen Walzwerk wohl 40 Formkästen herstellen und auch in eiligen Fällen einige Kästen ohne Unterschied der Größe, von 500 bis 4000 mmIn the case of cast molding boxes, when the mold is knocked loose, the flanges in particular are affected many times damaged or the boxes crack in two. The object of the invention is to forge molding boxes made of Siemens-Martin steel and to roll. In such cases, the above defects are excluded and the life expectancy is significantly longer. This process also allows for faster procurement very helpful, as one day on a specially created The rolling mill will probably produce 40 molding boxes and, in urgent cases, some boxes without Difference in size, from 500 to 4000 mm

Λ5 Durchmesser, sofort anfertigen kann, während zur Herstellung gegossener Kästen durch die zeitraubende Herstellung und Trocknung der Form, das Erkalten und Trichterabstechen viel mehr Zeit benötigt wird. Auch können die geschmiedeten Kästen im Notfall viel ^leichter auf dem oben erwähnten Walzwerk gerichtet werden. Die Herstellung der aus Siemens-Martin-Stahl geschmiedeten und gewalzten Formkästen geschieht auf folgende, bereits bei der Erzeugung von Radbandagen angewandte Weise:Λ5 diameter, can manufacture instantly, while for the manufacture of cast boxes through the time-consuming production and drying of the mold, cooling and funnel tapping much more time is needed. The forged boxes can also do a lot in an emergency ^ can be straightened more easily on the rolling mill mentioned above. The manufacture of the Siemens-Martin steel forged and rolled molding boxes happens on the following, already used in the production of wheel bandages:

Man schmiedet einen Siemens-Martin-Block (Fig. 1) unter dem Hammer oder einer Presse zur Scheibe und locht diese dann (Fig. 2). Darauf bringt man die Scheibe auf einen Hornsattel, gibt ihr runde Form, schmiedet sie weiter aus und macht bereits das äußere Profil fertig (Fig. 3). Das so roh vorgeschmiedete Stück wird dann auf eigens hierzu geschaffenem Walzwerk auf den gewünschten Durchmesser gebracht. Fig. 5 zeigt den fertig ausgewalzten Kasten. Zum Einhängen der Kranketten nötige Zapfen o. dgl. lassen sich nachher leicht an die Flanschen anschrauben.A Siemens-Martin block (Fig. 1) is forged under a hammer or a press to the disc and then perforates it (Fig. 2). Then you bring the disc to you Horn saddle, gives it a round shape, forges it further and already makes the outer one Profile finished (Fig. 3). The rough forged piece is then specially created for this purpose Rolling mill brought to the desired diameter. Fig. 5 shows the completely rolled out box. For hanging the Pins or the like required for crane chains can easily be screwed onto the flanges afterwards.
