Abstract
A method for carrying out shot blasting treatment on the surface of a steel core wire of a bimetallic wire comprises the steps of impacting a steel core wire which continuously moves after lead quenching by using steel shots continuously thrown at a high speed in a shot blasting treatment chamber, knocking off oxides formed on the surface of the steel core wire in the heating and lead quenching processes, wherein the throwing speed of the steel shots is 70-75 m/s, the outer diameter of each steel shot is 0.2-0.4 mm, and the moving speed of the steel core wire is 120-150 m/min. The steel shots are continuously thrown out at high speed by a nozzle which is communicated with a high-speed rotating impeller of a fan arranged outside the shot blasting treatment chamber and is arranged in the shot blasting treatment chamber. The method for removing the surface oxide of the steel core wire of the bimetallic wire has the advantages of high efficiency, low energy consumption and no pollution. And after the steel shots are thrown out at high speed and impact the steel core wire, the oxides on the surface of the steel core wire can be knocked down, pits with different depths are formed on the surface of the steel core wire, and after the bimetallic wire is manufactured by coating an aluminum layer or a copper layer, the binding force between the aluminum layer or the copper layer and the steel core wire is strong, and the manufactured bimetallic wire is high in quality.
Description
Technical field
The present invention relates to a kind of to metal wire surface-treated method, the method that especially a kind of steel core wire shotblasting to bimetallic conductor is handled.
Background technology
Bimetallic conductor generally has aluminium lamination clad steel wire and two kinds of structures of copper layer clad steel wire.The steel core wire of existing bimetallic conductor is to make like this: the steel wire in the required line footpath that will make by wire drawing, and be heated to and enter lead pan again after the uniform temperature and carry out patenting, promptly make the steel core wire of bimetallic conductor after the cooling.But this steel core wire surface in heating and patented process can form the oxide skin(coating) of one deck densification, and the main component of oxide skin(coating) is the mixture of di-iron trioxide and ferrous oxide.This steel core wire is because there is oxide skin(coating) on the surface, coating after aluminium lamination or copper layer make bimetallic conductor, and the adhesion of aluminium lamination or copper layer and steel core wire is had a strong impact on, and prepared bimetallic conductor is of low quality.So, before steel core wire outsourcing alclad or copper layer, need to remove the oxide on steel core wire surface.The existing method of removing the oxide on steel core wire surface has two kinds:
A kind of method is to increase cleaning equipment to remove oxide on surface in two steps:
First step physical method is by peeling off its surperficial oxide to an amount of distortion of the steel core wire after the patenting;
Second step was used chemical method, under certain temperature condition, thereby used phosphoric acid and the oxide reaction of not peeling off after the first step that remaining most of oxide is peeled off.
Behind above two steps removal steel core wire oxide on surface, before coating aluminium lamination or copper layer, carry out on-line cleaning again, so basically can be with the oxide removal on steel core wire surface.But this method is owing to used phosphoric acid, the phosphide that is produced can cause water to pollute, and energy consumption is higher, and cost is big.
Another kind method is that steel core wire directly carries out the on-line cleaning oxide on surface after patenting.
But, the steel core wire surface oxidation easily after cleaning with the method, the resting period slightly length will form new oxide skin(coating) again.
Summary of the invention
In order to overcome the deficiency of two kinds of methods that have the steel core wire oxide on surface of removing bimetallic conductor now, the invention provides a kind of method that the steel core wire shotblasting of bimetallic conductor is handled, can effectively remove the steel core wire oxide on surface, coating after aluminium lamination or copper layer make bimetallic conductor, the adhesion of aluminium lamination or copper layer and steel core wire is strong, the bimetallic conductor quality height that makes.
A kind of method that the steel core wire shotblasting of bimetallic conductor is handled provided by the invention, the shot bump of dishing out in the indoor high-speed and continuous of Shot Blasting continues mobile steel core wire after patenting, the steel core wire oxide that the surface forms in heating and patented process is shot down, the speed that shot is dished out is the 70-75 meter per second, the external diameter of every shot is the 0.2-0.4 millimeter, the speed that steel core wire moves be 120-150 rice/minute.
Shot among the present invention can be located at the indoor shower nozzle high-speed and continuous of Shot Blasting with the impeller connection of the high speed rotation that is located at the outdoor blower fan of Shot Blasting and dish out.
The invention has the beneficial effects as follows: adopt steel core wire oxide on surface that method of the present invention removes bimetallic conductor not only efficient height, energy consumption low, do not produce pollution.And, the shot continuous high speed bump of dishing out both can shoot down the oxide on steel core wire surface behind the steel core wire, also formed deep mixed pit on the steel core wire surface, was coating after aluminium lamination or copper layer make bimetallic conductor, the adhesion of aluminium lamination or copper layer and steel core wire is strong, the bimetallic conductor quality height that makes.
Description of drawings
Fig. 1 is the schematic diagram of use of the present invention.
In Fig. 1,1, the Shot Blasting chamber, 2, shot, 3, steel core wire, 4, shower nozzle, 5, the shot collecting board, 6, the eyelet of shot collecting board.
The specific embodiment
With reference to Fig. 1, with external diameter is that the shot 2 of 0.2-0.4 millimeter is put into the draught fan impeller that places Shot Blasting chamber 1 outer, draught fan impeller is communicated with shower nozzle 4 in placing Shot Blasting chamber 1, adjust the rotary speed of draught fan impeller, shot 2 is dished out from shower nozzle 4 in Shot Blasting chamber 1 continuously, and speed reaches the 70-75 meter per second; The steel core wire 3 of shot 2 bump through continuing after the patenting to move Shot Blasting chamber 1 in shoots down the oxide on steel core wire 3 surfaces, simultaneously at the deep mixed pit of steel core wire 3 surface formation; The speed that steel core wire 3 moves be 120-150 rice/minute.The steel core wire 3 that uses method of the present invention to handle coats after aluminium laminations or copper layer make bimetallic conductor, the adhesion enhancing of aluminium lamination or copper layer and steel core wire 3.Be scattering into behind shot 2 bump steel core wires 3 surfaces fall into again on the shot collecting board 5 that has eyelet 6 behind the gatherer reusable.
