摘要： A pull-back type indirect extrusion press designed so that the scalping of billets can be effected inside the press independently of extrusion cycles and the scalped billet is allowed to stand by in a billet extrusion standby space which is provided with a heating element to heat the standby billet to maintain the same at a required temperature and into which a billet oxidation-preventive gas is admitted to prevent oxidation of the standby billet.
