Wire rod feeding method, wire rod feeding device and casting blank

Номер: CN104278127A
Автор: ZUO LIJIE, HUANG ZHOUHUA
Принадлежит:

The invention provides a wire rod feeding method, a wire rod feeding device and a casting blank. The wire rod feeding method comprises the following steps: continuously introducing a protective gas to a wire rod feeding pipe by virtue of an air inlet on the wire rod feeding pipe and extending the outlet of the wire rod feeding pipe into molten metal; and extending a wire rod from the inlet of the wire rod feeding pipe to the molten metal along the wire rod feeding pipe. According to the wire rod feeding method provided by the invention, the wire rod can extend into any position of the molten metal so as to realize the purpose of deep wire rod feeding, so that the wire rod feeding yield is effectively improved and the waste on the wire rod is effectively reduced. Meanwhile, bubbles of the gasified fed wire rod in a process of moving toward the surface layer of the molten metal are mixed with the protective gas, so that the partial pressure of mixed bubbles is effectively alleviated, thereby ...

Preparation method of copper-aluminum gradient alloy submarine cable welding joint

Номер: CN116571747A
Принадлежит:

The invention discloses a preparation method of a copper-aluminum gradient alloy submarine cable welding joint, which comprises the following steps of: preparing copper-aluminum alloy powder with different mixing proportions by using a mechanical stirring mode, carrying out vibration densification and extrusion on powder blanks arranged according to gradients by adopting a cold isostatic pressing molding technology, preparing a copper-aluminum gradient blank through cold isostatic pressing, and carrying out heat treatment on the copper-aluminum gradient blank to obtain the copper-aluminum gradient alloy submarine cable welding joint. The copper-aluminum gradient material is prepared through equal channel angular pressing and heat treatment; according to the cold isostatic pressing and equal channel angular pressing processes adopted by the invention, the copper-aluminum ratio is controllable through pre-mechanical mixing; under the condition that the cross sectional area and the shape of ...
