Description
Technical field
The present invention relates to copper cash technology field, more particularly to ultra-fine copper cash hot dip process of tin.
Background technology
In electric wire production, the most frequently used plating wire is tinned wird, and it is mainly used in rubber covered mining
The conductor wire core of cable, retardant cable of locomotives and cable for ship etc., and electric wire external shield braiding layer.Copper wire tin-plating
Rubber that the oxidation and copper cash and rubber contacts that copper cash can effectively be prevented afterwards cause is tacky, copper cash blackening the problems such as, while carrying
The weldability of cable service life high and core.
At present, the production of China's line cable industry tinned wird, mainly has chemical plating stannum (electrotinning) and physics tin plating (hot tinning)
Two ways.Electrotinning is the more advanced mode of production, and its major advantage is uniform thickness of coating, and can arbitrarily be controlled, but
Compared with hot dip tin complex, operation requires that strictly equipment price is higher to its technique.Hot tinning process is simple, and equipment price is low, because
And used by many producers.Because the technique of each factory's hot tinning is not quite similar, the quality of the tinned wird of production is also different.
Especially in ultra-fine copper cash（Diameter is less than 0.2mm）Hot dip process of tin in, it is easy to produce broken string, tin layers the problems such as come off.
The content of the invention
The present invention provides a kind of hot dip process of tin of ultra-fine copper cash, can effectively reduce broken string, the probability that tin layers come off, and wraps
Include step:
1）Wire Drawing is carried out using the copper bar of purity >=99.95%, copper cash of the diameter less than 0.2mm is made；
2）Annealing;Annealing temperature is 230 ~ 260 DEG C, annealing time >=11S；
3）Pickling;Using the mixed liquor of zinc chloride, ammonium chloride, sodium chloride, hydrochloric acid, triethanolamine, emulsifying agent and water as pickling
Liquid, and by the way of felt line ball, be regularly cast on felt with pickle；
4）Hot tinning;At 240 ~ 260 DEG C, tin plating mould uses diamond mould, the hole of tin plating mould to the tin liquor temperature control melted in tin stove
Footpath 0.001mm bigger than copper wire diameter.
5）Cooling;The copper cash after tin plating is cooled down with water, by the way of felt line ball, water is drenched into note in felt
On, copper cash is carried out using blower fan then it is air-cooled, and by copper cash water drying；
6）Traction take-up.
Preferably, in hot tinning, stratus mother or charcoal powder are covered on the tin liquor surface of fusing, to completely cut off air and tin
The contact on liquid surface, prevents tin liquor surface oxidation.
Preferably, hot tinning uses No. 2 tin material.
Preferably, in hot tinning, a tin liquor is changed every two weeks.
Preferably, time of the copper cash in tin stove is not less than 0.02S.
Preferably, when drawing take-up, hauling speed is 120 ~ 150m/min
The hot dip process of tin of the ultra-fine copper cash that the present invention is provided, by controlling copper wire copper content, using acid washing method by copper wire table
Face is fully cleaned, and is made annealing treatment so as to improve the tensile strength of copper wire, and tin plating complete using suitable annealing temperature
Into it is rear using water-cooled combine it is air-cooled by the way of, make layer quickly cool down it is firm cover on copper wire surface, can effectively reduce broken string,
The probability that tin layers come off.
Specific embodiment
To make those skilled in the art be better understood from the present invention, further is made to the present invention with reference to specific embodiment
Description.
In the specific implementation, raw material first need to select the copper bar of purity >=99.95% to carry out Wire Drawing, be made diameter small
In the copper cash of 0.2mm, can be avoided because oxidation impurities are more so that tin layers are attached when follow-up tin plating on copper cash from purity copper bar high
Insecure；Then copper cash is annealed, annealing temperature is set as 250 DEG C, and the time is 12S；Then zinc chloride, chlorination are used
Pickle is regularly cast in felt by the mixed liquor of ammonium, sodium chloride, hydrochloric acid, triethanolamine, emulsifying agent and water as pickle
On, and pickling is carried out by the way of felt line ball, to remove the oxidation impurities of copper line surface；Enter into tin stove after the completion of pickling
Row is tin plating, and wherein at 250 DEG C, tin plating mould need to use diamond mould to tin liquor temperature control, to ensure preferable tin layers form, tin scraping mould
The big 0.001mm of aperture ratio copper wire diameter, tin slab used by hot tinning refers to No. two technical requirements of tin in GB/T728-1984；
In hot tinning, stratus mother or charcoal powder are covered on the tin liquor surface of fusing, to completely cut off the contact of air and tin liquor surface, prevented
Only tin liquor surface oxidation, and change a tin liquor every two weeks；To ensure that tin liquor is sufficiently adhering to copper line surface, attachment is formed
Good tin layers, time of the copper cash in tin stove is not less than 0.02S；When finally drawing take-up, to prevent broken string, hauling speed is not
It is preferably too fast, it is advisable with 120 m/min.
Above-described embodiment is only specific embodiment of the invention, and its description is more specific and in detail, but can not therefore and
It is interpreted as the limitation to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, not taking off
On the premise of present inventive concept, various modifications and improvements can be made, these obvious alternative forms belong to this
The protection domain of invention.
