Brikett zur Einbringung von Legierungselementen in Eisen schmelzenMelt briquette for the introduction of alloying elements into iron
Beschreibung Bei der Erschmelzung von Eisen-Kohlenstoff-GuB-Legierungen, allgemein auch GuReisen genannt, müssen der Ausgangsschmelze weitere Legierungselemente wie z. B. Silizium, Kohlenstoff, Mangan, Phosphor usw. zu gesetzt werden.Description When melting iron-carbon-GuB alloys, Commonly also called GuReisen, the starting melt must contain additional alloying elements such as B. silicon, carbon, manganese, phosphorus, etc. to be set.
Diese Legierungselemente werden in Form von Vorlegierungen oder Ver bindungen in körniger oder stückiger Form der Gattierung des Schmelzaggregates zugesetzt.These alloy elements are in the form of master alloys or ver Bonds in granular or lumpy form added to the charge of the melting unit.
Bei bestimmten Schmelzaggregaten, z. B. Kupol-Öfen, Trommel-Üfen werden die Legierungselemente aus technischen, metallurgischen und wirtschaftlichen Gründen in brikettierter Form verwandt.With certain melting units, e.g. B. cupola ovens, drum ovens the alloying elements for technical, metallurgical and economic reasons related in briquette form.
Diese Briketts werden unter Verwendung von Zementen, Kalk oder Ton allein oder in Mischungen hergestellt. Die Bindung ist hydraulisch.These briquettes are made using cement, lime or clay produced alone or in mixtures. The binding is hydraulic.
Die Aushärtung erfolgt an der Luft oder im Dampfofen.The curing takes place in the air or in a steam oven.
Hydraulisch gebundene Briketts haben einen Binde-Anteil von 15 - 25 %.Hydraulically bound briquettes have a binding content of 15 - 25 %.
Dieser besteht im wesentlichen aus CaO, A1203, SiO2 und Kristall wasser.This essentially consists of CaO, A1203, SiO2 and crystal water.
Beim Einsatz solcher Briketts muB der Binder im Schmelzaggregat geschmolzen werden, damit das oder die Legierungselemente frei werden und in die Eisenschmelze übergehen können. Der geschmolzene Binder be-einflußt und verändert naturgemäB die gewollte normale Schlacke.When using such briquettes, the binder must be melted in the melting unit so that the alloying element or elements are released and into the iron melt can pass over. The molten binder naturally influences and changes them wanted normal slag.
Zusammengefaßt wird festgestellt, daß hydraulisch gebundene Briketts aufgrund des Bindergehaltes zum Aufschmelzen zusätzliche Energie benötigen und die Schlackenzusammensetzung be-einflussen.In summary, it is stated that hydraulically bound briquettes require additional energy for melting due to the binder content and the Influence slag composition.
Aufgrund des ungünstigen Verhältnisses von Nutzinhalt zum tatsächlichen Gewicht entstehen unnötige Fracht- und Lagerkosten.Due to the unfavorable ratio of useful content to actual content Weight creates unnecessary freight and storage costs.
Dem Erfindungsgedanken liegt zugrunde, ein Legierungsbrikett herzustellen, das bei gleichem Nutzinhalt wesentlich leichter ist, dessen Bindemittel den Wärmehaushalt des Schmelzaggregates nicht belastet, die Schlacke nicht be-einflußt und das Legierungselement vor vorzeitigem Abbrand schützt.The idea of the invention is based on producing an alloy briquette, which is much lighter with the same useful content, its binding agent the heat balance of the smelting unit is not loaded, the slag and the alloying element are not affected protects against premature burn-up.
Die Lösung des Problemes wird dadurch erreicht, daß als Binder hoch-molekulare Kohlentisserstoff-Gemische verwendet werden.The solution to the problem is achieved by using high molecular weight binders Carbon fiber mixtures are used.
Bei Verwendung solcher Binder liegt der Anteil bei 3,5 - 7,0 46 Er umhüllt die körnigen Legierungselemente. Beim Erhitzen verkokt der Binder und schützt das Legierungselement vor Abbrand. Der Binder selbst verbrennt fast rückstandslos, da der Asche-Anteil bei max. 0,5 qd liegt.When using such binders, the proportion is 3.5 - 7.0 46 Er envelops the granular alloy elements. When heated, the binder cokes and protects the alloying element before burn-up. The binder itself burns almost completely, because the ash content is max. 0.5 qd.
