摘　　要： 热型连铸工艺可实现定向凝固，并且铸件与铸型间的摩擦力很小。本文介绍了用热型连铸工艺开发的单晶铜杆，用于高质量传输数字信号和模拟信号；柱晶组织的CuAlNi形状记忆合金丝，消除了铜基记忆合金的晶界应力集中，大大提高合金的力学性能和记忆性能；具有内肋片的铜管，提高换热效率3～5倍；连铸了塑性加工难度很大的白铜管坯，提高了塑性加工性能和耐海水腐蚀性能。 Ohno Continuous Casting（OCC） technology can realize unidirectional solidification and the friction between casting and mold is very small. The copper rod with single crystal developed by OCC is introduced, which can effectively transmit digital and analog signals. CuAINi shape memory alloy wires with columnar grain structure eliminate stress concentration on grain boundaries, thus enhances mechanical and memory properties. The heat exchange efficient of copper tubes with internal ribs increases 3-5 times. The plastic forming performance and corrosion resistance to sea water has been increased when cupronickel tubes, which is difficult to work by deforming, is manufactured by OCC.
