  Abrieb- und druckfestes Graphitagglomerat und Verfahren zu seiner Herstellung 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 maschine innig gemischt, in Formen ausgegossen und mit einem Vibrationsrüttler auf ein Raumgewicht von   2, 1 g/cm3 verdichtet. Anschliessend   wird das Gemisch 14 Tage an der Luft abbinden gelassen, danach mit Abbauhämmern zerkleinert und abgesiebt. 



   PATENTANSPRÜCHE : 
1. Abrieb- und druckfestes Graphitagglomerat, insbesondere zur Verwendung als Zuschlagstoff im Hochofenmöller, dadurch gekennzeichnet, dass es aus Graphit mit dem Korngrössenbereich von 0, 01 bis 100 mm, vorzugsweise 0,5 bis 30 mm, und Zement besteht, wobei der Zementanteil 4, 5-13 Gew. -% beträgt.

 <Desc / Clms Page number 2>

 machine mixed intimately, poured into molds and compacted with a vibration shaker to a density of 2.1 g / cm3. The mixture is then left to set in the air for 14 days, then comminuted with demolition hammers and sieved.



   PATENT CLAIMS:
1. Abrasion-resistant and pressure-resistant graphite agglomerate, in particular for use as an aggregate in the blast furnace oiler, characterized in that it consists of graphite with a grain size range of 0.01 to 100 mm, preferably 0.5 to 30 mm, and cement, the cement fraction 4 , 5-13% by weight.

Claims (1)

2. Graphitagglomerat nach Anspruch 1, dadurch gekennzeichnet, dass die Kornverteilungskurve des Graphits etwa derjenigen der Fullerkurve entspricht. 2. graphite agglomerate according to claim 1, characterized in that the particle size distribution curve of the graphite corresponds approximately to that of the Fuller curve. 3. Verfahren zur Herstellung eines Graphitagglomerats nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass entsprechend ausgewähltes Graphitmaterial mit einer Zementmenge, die innerhalb des in Anspruch 1 genannten Bereiches liegt, und der erforderlichen Menge Wasser innig gemischt, anschliessend auf ein Raumgewicht von 1,5 bis 2,5 g/cm3, vorzugsweise 1,8 bis 2,2 g/cm3, verdichtet, hierauf durch Lufttrocknung auf eine Druckfestigkeit von 50 bis 200 kg/cm2, vorzugsweise 100 bis 180 kg/cnr', erhärten gelassen und gegebenenfalls nachfolgend auf die gewünschte Korngrösse, z. B. grösser als 30 mm, zerkleinert wird. 3. A method for producing a graphite agglomerate according to claim 1 or 2, characterized in that appropriately selected graphite material is intimately mixed with an amount of cement which is within the range mentioned in claim 1 and the required amount of water, then to a density of 1.5 up to 2.5 g / cm3, preferably 1.8 to 2.2 g / cm3, then allowed to harden by air drying to a compressive strength of 50 to 200 kg / cm2, preferably 100 to 180 kg / cm3, and optionally subsequently to the desired grain size, e.g. B. larger than 30 mm, is crushed.
