Method and device for fixing an insert of a refractory material to a stool of an ingot mold, in which a weight having a metal flow way or path is placed on top of an insert fitted within the hollow of the stool, and a molten joint metal of cast iron or steel is poured into a gap between the insert and the hollow of the stool to form the joint using the metal flow way or path, and the joint metal is solidified. The weight prevents the insert from floating up, and the metal flow way distributes the molten metal uniformly to the top opening of the gap. A close contact of the insert and stool is thus obtained and it enhances the advantages of using an insert of carbon-bonded-silicon carbide-graphite material having a high strength and enough thermal conductivity to prevent internal defects of the ingot metal, because of its less interruption of the heat flow across the joint.
