    • Molds for continuous casting machines are made by providing a plurality of different tubular blanks of copper or copper based alloys; selecting a particular blank and feeding same to a first working station in which the blank is provided with a thrust mount such as a rim against which a mandrel to be inserted can abut during subsequent working; a particular mandrel is selected from among a plurality of stored mandrels and forced into the rimmed tubular blank; by means of a die, the tubular blank is forced onto the mandrel in all around, tight, surface to surface contact while preferably a normal orientation of the die is maintained in relation to the mandrel passing through; thereafter the mandrel is recovered from the blank and either returned to the station of mandrel insertion or to the mandrel store.
    • 用于连续铸造机的模具通过提供铜或铜基合金的多个不同的管状坯料制成; 选择特定的坯料并将其馈送到第一工作站,其中坯件设置有推力安装件,例如在随后的加工期间待插入的心轴可抵靠的推力安装件; 从多个存储的心轴中选择特定的心轴并且被迫进入边缘的管状坯料; 通过模具,管状坯料在所有周围,紧密的表面到表面接触处被迫到心轴上,同时优选地相对于心轴通过而保持模具的正常取向; 此后,心轴从坯料中回收并返回到心轴插入工位或芯棒存储器。
