Abstract
The invention provides a tin-bronze rod with extremely high tin content which comprises the following components in percentage by weight: 23%-31% of tin and the balance of copper. A preparation method for the tin-bronze rod provided by the invention comprises the following steps that: tin and copper are directly smelted in a main frequency furnace at a certain temperature, and the corresponding thermal insulation and perception are carried out according to proper conditions to prevent the phenomenon of alloy segregation occurrence; alloy components are ensured through detection by advanced equipment; the alloy is directly cast to rod in a continuous casting manner so that the cost is low; and, because high-temperature treatment equipment are used in an electroplating process, the alloy rod can be directly applied to the electroplating, the rod is slowly melted in the high temperature electroplating equipment, the melted rod is adsorbed on the surface of an electroplating carrier material, and therefore, the rod can be directly used in the electroplating process to prevent from repeatedly carrying out grinding and micro-processing technologies which are for metal powder processing so that the production cost is reduced and the production efficiency is improved.
Description
Technical field
The present invention relates to the alloy bar field, particularly relate to a kind of extra-high-speed tin-bronze rod, and the preparation method of this alloy bar.
Background technology
In the Metal plating industry, need to use the extra high gun-metal powder of stanniferous amount other metals are electroplated.The production stage of the extra high powdered alloy of this stanniferous amount is: at first use the method for sand casting or die casting that tin and copper are proportionally carried out melting and ingot casting; Secondly, the mode of using machine to grind is ground copper ingot, and copper ingot is ground to form copper powder.There is following problem in this production method: at first, be easy to occur segregation phenomena in the time of sand casting and die casting copper water, can directly affect the homogeneity that the later stage powder is electroplated like this, cause electroplating unsuccessfully; Secondly, the granular size that can occur powder in the process of lapping is inhomogeneous, needs further plug choosing, and does the little processing of metal and make its graininess evenly available, has so just increased the cost of use powder metallurgy; Again, because the little complex treatment process of later stage metal has caused production efficiency low.
