In Kleinbessemereien, welche sich mit der Herstellung von Stahlformguß beschäftigen, ist es gebräuchlich, der erblasenen Flußeisencharge einen Zusatz einer Silicium - Mangan-Legierung zu geben, um den Stahl ruhig und zum Gießen geeignet zu machen.In small-scale workshops, which deal with the production of cast steel, it is customary to add a silicon-manganese alloy to the blown iron charge to give to make the steel calm and suitable for casting.
Um das verhältnismäßig kleine Metallbad durch diesen Zusatz nicht unnötig abzukühlen, wird letzterer in konzentrierter Form, d. h. alsIn order not to cool down the relatively small metal bath unnecessarily by this addition, the latter is in concentrated form, d. H. as
ίο hochprozentiges Ferromangan bzw. Ferrosilicium im festen, angewärmten oder geschmolzenen Zustande zugefügt.ίο high-percentage ferromanganese or ferrosilicon added in the solid, warmed or molten state.
In Großbessemereien pflegt man diesen Zusatz in Form von Spiegeleisen oder ähnliehen Silicium-Mangan-Legierungen in kleinen Kupolöfen für sich zu schmelzen und von dort unmittelbar in die erblasene Charge abzustechen. In large-scale repair shops, this addition is used in the form of fried iron or something similar To melt silicon-manganese alloys in small cupolas for themselves and from there to pierce directly into the blown charge.
Auch ist es bekannt, in Konverterchargen einen Zusatz von Roheisen zwecks Oxydierens und Rückkohlens zu machen.It is also known to add pig iron to converter batches for the purpose of oxidizing and to make charcoal.
Der Zweck der Neuerung, deren Brauchbarkeit für den technischen Großbetrieb durch zahlreiche Versuche festgelegt wurde, besteht nun darin, dem erblasenen Metallbade zum Beruhigen dasselbe geschmolzene Hämatitroheisen zuzufügen, welches als Rinneneisen aus dem Kupolofen in den Konverter fließt und dort gebessemert wird.The purpose of the innovation, its usefulness for large-scale technical operations Numerous attempts have been made, is now to use the blown metal bath Calm adding the same molten hematite iron that is used as gutter iron flows from the cupola into the converter and is improved there.
Es ist also nicht nötig, wie bisher eine neue, erforderlichenfalls an dritter Stelle zu schmelzende Legierung als Beruhigungsmittel zu benutzen, sondern es wird nach beendetem Blasen aus dem Kupolofen, welcher das Hämatitroheisen für die Stahlchargen liefert, eine kleine Menge abgestochen und direkt oder vorteilhaft durch eine Gabelpfanne mit bekanntem Inhalt dem Metallbade zugesetzt. Der Kohlenstoff dieses Zusatzes von Hämatitroheisen ist es, welcher auf. die im Metallbade gelösten Oxyde kräftig einwirkt und dieselben unter Bildung von Kohlenoxydgasen zerstört. Das Hämatitroheisen dient also nicht zum Härten, sondern nur zum Beruhigen des Metallbades, und da von seinem Kohlenstoff nach zahlreichen Versuchen mehr als 50 Prozent bei der Reaktion verbrennen, so können zur Erzielung von Flußeisenformguß bis zu 10 Prozent an Hämatiteisen dem Bade zugesetzt werden.So it is not necessary, as before, to add a new one, if necessary in the third position Melting alloy to use as a sedative, instead it is finished after Bubbles from the cupola, which supplies the hematite iron for the steel batches, Tear off a small amount and use it directly or advantageously through a fork pan known content added to the metal bath. The carbon of this addition of hematite hot iron is it which on. the oxides dissolved in the metal bath act vigorously and the same destroyed with the formation of carbon dioxide gases. The hematite metal does not serve to Hardening, but only to calm the metal bath, and there its carbon after numerous attempts more than 50 percent burn in the reaction, so can Up to 10 percent of hematite iron is added to the bath to achieve fluoro-iron castings will.
