EMI1.1
EMI1.2
Koks im elektrischen Lichtbogen zusammengeschmolzen und das hiebel entatehende Erzeugnis, das sogenannte Karbid, der Einwirkung des Luftstickstoffes in Asotieröfen unter- worfen. Die bisher verwendeten Einsatze für die Azotierofon bestehen aus einem unten geschlossenen Metallzylinder, dessen Mantel rund gelocht ist. Im Innern sind die Ein- sätze mit Wellpappe ausgekleidet, damit das in Pulverform eingebrachte Karbid nicht durch die Öffnungen herausfallen kann.
Zweck der Erfindung ist die Beseitigung der Papiereinlage der Einsitzt für Azotier- öfen, welche den Durchtrittsquerschnitt für die Luft in ubzutrlg1icher Weise verringern und ausserdem an sich unpraktisch und unwirtschaftlich sind. Das angestrebte Ziel wird dadurch erreicht, das der Mantel des Zylinders nicht mehr rund durchgeiocht wird, aondern maultaschenförmigeÖffnungenohneMaterialverlustenthält.
Auf der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel dargestellt. Es zeigt :
Fig. 1 den Einsatz in Ansicht,
Fig. 2 ein Stuck der Einsatzwandung in grösserem Massstabs und
Fig. 3 den Schnitt nach A-B der Fig. 2.
Der Einsatz besteht in bekannter Weise aus einem Metallzylinder a, welcher unten durch einen Boden vorschlossen ist. Der Zylinder besitzt maultaschenförmige Öffnungen b,

EMI1.1
EMI1.2
Coke melted together in an electric arc and the Hiebel entatehende product, the so-called carbide, subjected to the action of atmospheric nitrogen in asotier ovens. The previously used inserts for the Azotierofon consist of a metal cylinder closed at the bottom, the jacket of which is perforated. Inside, the inserts are lined with corrugated cardboard so that the powdered carbide cannot fall out through the openings.
The purpose of the invention is to eliminate the paper insert of the seats for azotizing ovens, which reduce the passage cross-section for the air in an unreasonable manner and, moreover, are inherently impractical and uneconomical. The aim is achieved in that the jacket of the cylinder is no longer perforated round, but instead contains mouth-shaped openings without any loss of material.
The subject of the invention is shown in an exemplary embodiment in the drawing. It shows :
Fig. 1 the insert in view,
2 shows a piece of the insert wall on a larger scale and
3 shows the section along A-B of FIG. 2.
The insert consists in a known manner of a metal cylinder a, which is closed at the bottom by a base. The cylinder has mouth-shaped openings b,
