GRAPHITIC REFRACTORIES AND PREPARATION METHOD THEREOF

An oxidation-resistant graphitic refractory is produced by melting aluminium (Al) at 1000 deg.C or more in the melting furnace (1), disperisng compressive inert gas and graphite powder into the molten aluminium, cooling and crushing the dispersed material by passing through the water-cooling roll (4...

Beschreibung
Zusammenfassung:	An oxidation-resistant graphitic refractory is produced by melting aluminium (Al) at 1000 deg.C or more in the melting furnace (1), disperisng compressive inert gas and graphite powder into the molten aluminium, cooling and crushing the dispersed material by passing through the water-cooling roll (4). The graphitic refractory has a good heat-impact and erossion property, is used as a heating container.
