俄罗斯铝业公司调整铸造产品结构的经验

在上世纪90年代中期以前,俄罗斯各铝厂基本上只生产原铝锭,铝加工厂用的锭坯都是各厂以原铝锭为基础重熔与铸造而成的。近几年来特别是进入新世纪以来,各铝厂的铸造车间根据各自特点加速了产品结构调整,增加了高附加值产品产量,压低了重熔铝锭的比例。俄罗斯铝业公司(Rusal)现以美国铝业公司(Alcoa)、加拿大铝业公司(Alcan)、海德鲁铝业公司(Hydro)为样板调整了铸造车间的产品结构,多生产附加值高的铸造锭坯,如轧制厂用的铝及铝合金扁锭、挤压厂用的铝合金圆锭、汽车零配件铸造厂用的铝-硅合金锭、电线电缆厂用的线杆(圆盘)、电子工业用的…

空心圆铸锭热顶铸造设备问世

我国挤压用空心圆铸锭（空心锭）的生产一般采用直接水冷（DC）立式半连续铸造工艺,或采用将实心圆铸锭经车皮和钻孔（或穿孔）成空心锭的方法来生产。直接水冷（DC）半连续铸造工艺生产的空心圆铸锭必须经过车皮和镗孔工序,这二种方法均存在铝耗大、成本高、效率低等问题。
