Description
Przedmiotem niniejszego wynalazku jest urzadzenie do wykonywania odlewów metalowych, które sklada isie, jak juz to by¬ lo opisane w patencie Nr 15329, z formy i grzejnika, zawierajacego przewodnik, po którym przepuszcza sie zmienny prad elek¬ tryczny o wysokiej czestotliwosci, przyczem grzejnik ten mozna ustawiac tak, aby ogrze¬ wal tylko czesc górna stopionego metalu, znajdujacego sie w formie, lub tez byl opu¬ szczany w sam metal zawarty w formie.Na rysunku podano tytulem przykladu trzy odmiany wynalazku, przyczem fig. 1 i 2 przedstawiaja przekroje pionowe wzdluz osi dwóch odmian wynalazku, i fig. 3 — szczegól trzeciej odmiany wynalazku.Urzadzenie uwidocznione na fig. 1 slu¬ zy do odlewania walca metalowego o wy¬ sokosci h1, zas urzadzenie, uwidocznione na fig. 2, sluzy do odlewania bloków stalowych.Urzadzenie to sklada sie z formy 7, do któ¬ rej wlewa sie stopiona stal, i z grzejnika 2.Grzejnik ten ma ksztalt tarczy, zaopatrzo¬ nej w przewodnik elektryczny 3, przez któ-ry przepuszcza sie zmienny prad elektrycz¬ ny, przyczem przewodnik ten mozna umie¬ scic ria spodzie tarczy tak, aby tworzyl spi¬ rale (fig. 3) znajdujaca sie w jednej pla¬ szczyznie; przewodnik ten posiada konce 5 i 6 do doprowadzania pradu elektrycznego. PLThe present invention relates to a device for casting metal which consists, as already described in Patent No. 15329, of a mold and a heater containing a conductor on which a high frequency alternating current is passed through the heater. may be positioned so as to heat only the upper part of the molten metal in the mold, or to be lowered into the metal itself contained in the mold. In the drawing, three variations of the invention are given by way of example, while Figures 1 and 2 are vertical sections. along the axis of the two variants of the invention, and Fig. 3 - a detail of the third variant of the invention. The apparatus shown in Fig. 1 is used to cast a metal cylinder h1 high, or the apparatus shown in Fig. 2 is used to cast steel blocks. The device consists of a mold 7 into which molten steel is poured, and a heater 2. This heater has the shape of a disk, provided with an electric conductor 3 through which to pass As an alternating current occurs, the conductor can be placed on the bottom of the disc so as to form spirals (Fig. 3) located in one plane; the conductor has ends 5 and 6 for introducing an electric current.
