Abstract
The invention discloses a manufacturing method for a rosin soldering tin bar. The method includes the following steps that (1) metal is pulverized and sieved, the metal comprises metallic nickel, metallic copper, metallic tin, metallic lead and metallic bismuth, and the metal is subjected to superfine pulverization and sieved through a 50-60 mesh screen; (2) soldering tin bar powder is weighed; (3) 10-15 parts of rosin is weighed; (4) melting of the soldering tin bar is carried out, the weighed metal powder is put into a melting furnace and subjected to primary melting stirring until the metal powder is completely melted, then the rosin obtained in the step (3) is added, and secondary melting stirring is carried out; and (5) moulding by casting is carried out, and a mixture obtained in the step (4) is poured into a mould to complete moulding by casting. According to the manufacturing method for the rosin soldering tin bar, operation is simple, the process is easy to control, and the manufactured soldering tin bar is low in melting point, low in cost and good in using effect.
Description
Technical field
The present invention relates to soldering tin bar field, particularly relate to a kind of preparation method of rosin soldering tin bar.
Background technology
Rosin belongs to scaling powder, and the purposes of its most critical is the effect of impregnation of solder and welded object when increasing welding, and existing soldering tin bar most existing use rosin in the process of welding infiltrates.
Summary of the invention
The preparation method of the rosin soldering tin bar that the technical problem that the present invention mainly solves is to provide a kind ofly does not need to use in addition rosin to carry out infiltrating, fusing point is low, result of use is good.
For solving the problems of the technologies described above, the invention provides a kind of preparation method of rosin soldering tin bar, comprising the following steps:
(1) pulverized and sieved by metal, metal comprises metallic nickel, metallic copper, metallic tin, metallic lead and bismuth metal, by broken for above-mentioned metal ultrafine powder, crosses 50-60 mesh sieve,
(2) take soldering tin bar powder, take the metallic nickel 2-5 part after sieving respectively, metallic copper 8-10 part, metallic tin 70-75 part, metallic lead 5-8 part, bismuth metal 0.2-0.3 part, described number is weight proportion,
(3) rosin 10-15 part is taken,
(4) fusing of soldering tin bar, drop in melting furnace by the above-mentioned metal dust taken, first time melts stirring, until after its whole fusing, add the rosin in step (3), carry out second time and melt stirring,
(5) moulding by casting, is poured on mould by the mixture obtained in step (4), moulding by casting.
In a preferred embodiment of the present invention, the fusion temperature that described first time fusing is stirred is 350-395 degree Celsius, and fusing time is 15-20 minute.
