Abstract
The invention relates to a hot-sprayed zinc-aluminum alloy wire and a preparation method thereof. The hot-sprayed zinc-aluminum alloy wire comprises the following components in percentage by weight: 2-20% of aluminum and the balance of zinc. The preparation method of the hot-sprayed zinc-aluminum alloy wire comprises the following steps of: feeding zinc and aluminum according to a component ratio, smelting and casting to form cylindrical zinc-aluminum alloy ingot materials; producing bar stocks by using a hot extrusion machine, and rolling the bar stocks by using a wire rolling machine to produce wire materials with the diameter phi of 3.0-4.5 mm; and then, repeatedly carrying out cold drawing on the wire materials by using a drawing die, so as to produce zinc-aluminum alloy wires with the diameter phi of 1.6-4 mm.. According to the preparation method, the drawing frequency during the forming of the zinc-aluminum alloy wires is greatly reduced, the alloy structure becomes more uniform during the process of rolling zinc-aluminum alloy, the tensile strength of the rolled wires is reduced by 8-10%, and the percentage elongation is increased by 12-15%, wire break can be avoided in a drawing process, the diameter of finished product wires is uniform, the production efficiency is greatly increased, the energy consumption and production cost are reduced, and the environmental pollution is lightened. Thus, the invention successfully provides an economical and feasible technology for the large-scale industrial production of the hot-sprayed zinc-aluminum alloy wires.
Description
Technical field
the present invention relates to a kind of thermal spraying alloy wire and production technique thereof.
Background technology
are the effectively reliable methods that at present steel is carried out anti-corrosive treatment at metal levels such as steel surface spraying zinc or aluminium.Its working method normally earlier becomes the bigger bar of diameter with zinc or aluminium fusion continuous casting; It is tempered and make the Spray Wire of any surface finish, the uniform Φ 1.6～4mm of diameter through the several times drawing to hold in both hands material then, and the steel surface that power supply heat or flame plating rifle are sprayed at through clean forms corrosion resistant protective layer.The existing zinc metal protection layer that generally uses is better to the electrochemical protection of iron and steel, but its solidity to corrosion is relatively poor, and corrosion failure is very fast in seawater; And the protection against corrosion of aluminum metal protective layer is stable, wear resistance is good, but electrochemical protection is relatively poor.The existing aluminium zinc coating of development had newly then both had the good electrical chemical protective like the zinc metal protection layer; Have good protection against corrosion stability, wear resistance again, but be a kind of novel high resistant metal protective layer of comparatively ideal anti-seawater corrosion like the aluminum metal protective layer.Yet the forming process of aluminium zinc Spray Wire is difficulty very.Because adopt the conventional pure zinc or the drawing method for processing of fine aluminium Spray Wire; Be drawn into the Spray Wire that is suitable for 1.6～4 millimeters of diameters that spray gun uses from the handful material of more than ten millimeter of diameter, need through more than 20 drawings step by step, but since in the aluminium zinc zinc and aluminium be easy to generate segregation and make alloy structure not too even; The plastic deformation resistance increases; Fracture of wire is even inadequately with the silk footpath when often causing drawing, and the hardness of Spray Wire is big, the application of not convenient spray gun.So far, do not find as yet to have to solve the way that aluminium zinc Spray Wire production efficiency is low, energy consumption is high, production cost is high and functional quality is not good enough, thereby, make this novel good high resistant metal protection coating materials still fail to obtain actual widely applying.
Summary of the invention
the object of the invention provides a kind of novel thermospray Zn-Al alloy wire and preparation method thereof.
Technical solution of the present invention is:
a kind of thermospray Zn-Al alloy wire, its component is by weight percentage: aluminium 2～20%, surplus are zinc.
aforesaid thermospray Zn-Al alloy wire preparation method; Comprise zinc, aluminium in the feed intake melting and be cast into cylindrical aluminium zinc ingot of component ratio; Process bar through heat extruder then; Thereafter hold in both hands material and be rolled into Φ 3.0～4.5mm wire rod through the rolling line machine, again with wire rod through the cold drawing of several times drawing-die, make the Zn-Al alloy wire of Φ 1.6～4mm.
as preferred, the Heating temperature of heat extruder hot extrusion is 270 ℃.
the invention has the beneficial effects as follows: because the aluminium zinc bar is processed the thermospray Zn-Al alloy wire product that wire rod is drawn into Φ 1.6～4mm more earlier through rolling, this has not only significantly reduced the drawing number of times that former cause aluminium zinc bar directly draws the thermospray Zn-Al alloy wire, and because aluminium zinc makes alloy structure more even in the operation of rolling; Make the wire rod tensile strength of rolling gained reduce by 8～10%, unit elongation improves 12～15%, and more helps drawing; Thereby guaranteed not fracture of wire of the drawing course of processing; The finished silk footpath is even, and hardness is moderate, any surface finish; Improved production efficiency greatly; Also significantly reduce the times of tempering of the course of processing simultaneously, reduced energy consumption and production cost, and alleviated environmental pollution.Thereby; The present invention successfully provides practical economically viable Technology for the large-scale industrial production of thermospray Zn-Al alloy wire, for this novel good high resistant metal protection coating materials of aluminium zinc obtains the actual widely condition created of applying.
