Description
Stahlartige Legierung für Kirchenglocken. Zum Gießen von Kirchenglocken wird eine stahlartige Legierung benötigt, die sehr dünnflüssig ist und ihre Dünnflüssigkeit lange beibehält, so daß sie die Formen genau und scharf ausfüllt, ohne vorzeitig matt zu werden. Diese Legierung enthält folgende Bestandteile: Kohlenstoff 2,8 Prozent, Silizium 0,24 Prozent, Mlangan o,31 Prozent, Phosphor o,64 Prozent und Schwefel o,o8 Prozent.Steel-like alloy for church bells. For casting church bells a steel-like alloy is required, which is very fluid and its fluidity long, so that it fills the shapes accurately and sharply without prematurely to become dull. This alloy contains the following components: carbon 2.8 percent, Silicon 0.24 percent, mlangan o.31 percent, phosphorus o.64 percent and sulfur o, o8 percent.
Zur Herstellung dieser Legierung wird zweckmäßig aus 8o Prozent altem Schmiedeeisen ,oder Stahl, io Prozent phosphorhaltigem Roheisen und io Prozent Gußbruch eine Vorgattierung verschmolzen, die in Sandformen zu Barren vergossen und nach dem Erkalten in Stücke geschlagen wird.For the production of this alloy it is expedient to use 80 percent old Wrought iron, or steel, 10 percent pig iron containing phosphorus and 10 percent broken cast iron a Vorgattierung fused, which poured into sand molds to ingots and after is beaten to pieces when cold.
Soll nun eine oder mehrere Glocken gegossen werden, so wird beispielsweise in einem Ofen mit Vorherd folgendermaßen gearbeitet: Der Ofen wird mit Koks gefüllt, und zwar 2 m über den Düsen. Dann folgen 25 kg Kalksteine, 6o Prozent Schmiedeeisen oder Stahl, 40 Prozent von ersterer Vorgattierung, dann folgen 6o kg Koks und 2o kg Kalksteine usw.If one or more bells are to be cast, for example work in a furnace with a forehearth as follows: the furnace is filled with coke, namely 2 m above the nozzles. This is followed by 25 kg of limestone, 60 percent wrought iron or steel, 40 percent of the first charge, followed by 60 kg of coke and 20 kg kg of limestone etc.
Ist der Vorherd mit flüssigem Metall gefüllt, so wird abgestochen und die Glocke gegossen.If the forehearth is filled with liquid metal, it is tapped and poured the bell.
Ein großer Vorteil ist der, daß diese Legierung bei schwachen und starken Querschnitten sehr gleichmäßig ausfällt, wodurch die Klangfülle gewinnt. Sie kann natürlich nicht nur in einem Kuppelofen mit Vorherd, sondern auch in einem gewöhnlichen Kuppelofen ohne Vorherd geschmolzen werden. Nur muß berücksichtigt werden, daß die Legierung dann weicher zusammengesetzt werden kann, da sie in diesem Falle bedeutend an Schwefel zunimmt, aber nicht so viel Gelegenheit hat, sich an Silizium aus der starken Schamottesteinausmauerung des Vorherdes anzureichern.A great advantage is that this alloy is used in weak and strong cross-sections turns out very evenly, which increases the richness of the sound. You can of course not only in a dome furnace with a forehearth, but also in one ordinary dome furnace can be melted without forehearth. Just must be considered that the alloy can then be composed softer because it is in this Trap increases significantly in sulfur, but does not have as much opportunity to get on Enrich silicon from the strong firebrick lining of the forehearth.
Durch den Zusatz von Schmiedeeisen oder Stahl wird ein bestimmter Härtegrad erzielt. Sind nun die Anforderungen, welche an die Legierung gestellt werden, derartige, daß eine geringere Härte genügt, wie z. B. bei der kleinen Glocke im Geläute, so muß, damit der Ton nicht zu schrill hindurchklingt gegenüber den dazugehörigen größeren Glocken, der Prozentsatz an Schmiedeeisen oder Stahl und Vorgattierung verringert und der Gußeisenbruchzusatä dementsprechend erhöht werden.The addition of wrought iron or steel creates a certain Degree of hardness achieved. Now are the requirements that are placed on the alloy be, such that a lower hardness is sufficient, such as. B. at the little bell in the bell, so must, so that the tone does not sound too shrill compared to the associated larger bells, the percentage of wrought iron or steel and Pre-charging is reduced and the cast iron fraction can be increased accordingly.
