METHOD OF COMPOSITE CASTING OF A ONE-PIECE CAST TOOL |
摘要 |
A method of one-piece casting of a tool with a working component of steel and a body of grey iron, and an interconnection zone therebetween is carried out in a single mould which is kept closed and unchanged during the casting. The steel is cast first from beneath and upwards, whereafter a pause is made. The casting of the grey iron is only carried out when the temperature of the steel in the intended interconnection zone has fallen to a temperature corresponding to the liquidus temperature of the steel minus approx. 30° to 150° C.
