Abstract
The invention discloses a manufacturing method for a copper-added soldering tin bar. The method includes the following steps that (1) soldering tin bar components are weighed, and 0.5-0.85 part, by weight, of metallic nickel, 70-75 parts, by weight, of metallic tin, 0.5-0.95 part, by weight, of metallic bismuth, 1-3.5 parts, by weight, of metallic lead, and 5-10 parts, by weight, of metallic copper are weighed; (2) melting of the soldering tin bar is carried out, and the weighed metal is put into a melting furnace and stirred sufficiently until all the metal is melted; and (3) moulding by casting is carried out, and a mixture obtained in the step (2) is poured into a mold to complete moulding by casting. In this way, the soldering tin bar manufactured through the manufacturing method for the copper-added soldering tin bar makes full use of the heat conducting performance of the metallic copper, the melting speed and soldering speed of soldering tin are increased, the soldering production effect is improved, and the using effect is better.
Description
Technical field
The present invention relates to scolding tin field, particularly relate to a kind of preparation method adding brazing tin bar.
Background technology
For the difficult point that copper and stainless dissimilar welding are also in welding operation, because the good heat-conducting effect of copper, and stainless heat conductivity is poor, the separately difference of both coefficients of expansion, if adopt the words of gas welding operation, be easy to cause the solder of melting in the process of welding to roll about and do not glue in face on stainless steel, the temperature now for both mother metals controls to be difficult point.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of preparation method adding brazing tin bar.
For solving the problems of the technologies described above, the invention provides a kind of preparation method adding brazing tin bar, comprising the following steps:
(1) take soldering tin bar component, take metallic nickel 0.5-0.85 part respectively, metallic tin 70-75 part, bismuth metal 0.5-0.95 part, metallic lead 1-3.5 part, metallic copper 5-10 part, described number is weight proportion,
(2) fusing of soldering tin bar, drops into melting furnace by the above-mentioned metal taken, fully stirs, until it all melts,
(3) moulding by casting, is poured on mould by the mixture obtained in step (2), moulding by casting.
In a preferred embodiment of the present invention, the temperature of described melting furnace remains on 330-365 degree Celsius, and fusing time is 10-15 minute.
In a preferred embodiment of the present invention, in described soldering tin bar component, also comprise 0.12-0.25 part gold.
In a preferred embodiment of the present invention, in described soldering tin bar component, also comprise 0.55-0.85 part rare earth alloy.
The invention has the beneficial effects as follows: the soldering tin bar that the preparation method that the present invention adds brazing tin bar is made takes full advantage of the heat conductivility of copper metal, enhance burn-off rate and the speed of welding of scolding tin, improve the production effect of welding, result of use is better.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention comprises:
Add a preparation method for brazing tin bar, comprise the following steps:
(1) take soldering tin bar component, take metallic nickel 0.5-0.85 part respectively, metallic tin 70-75 part, bismuth metal 0.5-0.95 part, metallic lead 1-3.5 part, metallic copper 5-10 part, described number is weight proportion,
(2) fusing of soldering tin bar, drops into melting furnace by the above-mentioned metal taken, fully stirs, until it all melts,
(3) moulding by casting, is poured on mould by the mixture obtained in step (2), moulding by casting.
This soldering tin bar takes full advantage of the heat conductivility of copper metal, and enhance burn-off rate and the speed of welding of scolding tin, improve the production effect of welding, result of use is better.
The temperature of described melting furnace remains on 330-365 degree Celsius, and fusing time is 10-15 minute.
0.12-0.25 part gold is also comprised in described soldering tin bar component.
0.55-0.85 part rare earth alloy is also comprised in described soldering tin bar component.
Be different from prior art, the soldering tin bar that the preparation method that the present invention adds brazing tin bar is made takes full advantage of the heat conductivility of copper metal, and enhance burn-off rate and the speed of welding of scolding tin, improve the production effect of welding, result of use is better.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
