Description
Technical field
The present invention relates to chrome zirconium copper alloy melting technique field, more particularly to a kind of high-strength highly-conductive chrome zirconium copper alloy melting to use
Refining agent and its application method.
Background technology
Microalloying copper alloy is due to the combination property such as outstanding mechanics, conductive and heat-conductive, anticorrosive, antifatigue, making
Its electric wire, IC blaster fuse frame materials, electric railway contact line and other need alloy conductive heat conductivility its
He is widely used in field.Wherein CuCrZr systems alloy is preferable height due to Cr and Zr strong precipitation enhancement
Intensity high-conductivity copper alloy material, its intensity and electrical conductivity are all well positioned to meet actual operation requirements.Moreover, it is anti-soft
Can be reached by changing temperature by 500 DEG C, and the founding environment for CuCrZr alloys is mainly based on vacuum condition at present, in antivacuum bar
Founding under part also obtained the attention of researcher in recent years.
Refining agent is that the antivacuum founding of chrome zirconium copper alloy is essential, and largely have impact on the performance of same ingot casting.
Often function is excessively single for the refining agent that the antivacuum founding of chrome zirconium copper alloy at present uses, and deaerating effect is undesirable, and to copper-based
Body pollution.Therefore, developing the more excellent high-strength highly-conductive chrome zirconium copper alloy refining agent for smelting of performance turns into this area urgent need solution
Problem certainly.
The content of the invention
The present invention proposes a kind of high-strength highly-conductive chrome zirconium copper alloy refining agent for smelting and its application method, and the present invention uses
Component and decontaminant components mating reaction are covered, there are good impurity and purification to act on to chrome zirconium copper alloy liquation, and effectively avoid
Oxidization burning loss in fusion process, the intensity and electric conductivity of material are improved, and it is pollution-free to copper alloy liquid.
A kind of high-strength highly-conductive chrome zirconium copper alloy refining agent for smelting proposed by the present invention, including covering component and purification group
Point；Wherein, decontaminant components include：Six calcium borides, fluotitanate, borofluoride, chlorine metal salt, rare earth.
