Abstract

A method for preparing a thermal spraying metal wire includes the following steps of: melting and casting raw material metal feeding into a cylindrical bar; using a rolling machine to roll the bar into a wire rod with the diameter being 3.0 to 4.5 mm; and carrying out limited times of cold drawing of a drawing die on the wire rod to obtain the thermal spraying wire with the diameter being smaller than 4 mm. The method in the invention firstly rolls the metal bar to produce the wire rod and draws the wire rod into the thermal spraying wire with the diameter being smaller than 4 mm, which not only greatly reduces drawing times needed in an existing method in which a metal bar is directly drawn into a thermal spraying metal wire, but also ensures unbroken wires in a drawing process as well as uniform wire diameter, moderate hardness and smooth surface of a product; the method in the invention can further improve production efficiency of the thermal spraying metal wire by more than 40% compared with that of a traditional direct drawing process, and greatly reduces tempering frequency in the processing process, thereby reducing energy consumption and production cost as well as environmental pollution.

Description

Thermal spraying a kind of preparation method wiry

Technical field

the present invention relates to thermal spraying contour machining procedure wiry.

Background technology

are effective, the reliable methods that at present steel is carried out anti-corrosion treatment at metal levels such as steel surface spraying zinc or aluminium.Its processing method is earlier zinc or aluminium fusion continuous casting to be become the bigger bar of diameter all the time; Hold in both hands then material tempered and through the several times drawing make any surface finish, evenly, typically have a diameter from the Spray Wire of Φ 1.2～4mm, the steel surface that this Spray Wire power supply heat or flame-spraying rifle are sprayed at through clean forms corrosion resistant overcoat.The processing and forming of above-mentioned Spray Wire will be drawn into from the handful material of more than ten millimeter of diameter and is suitable for the Spray Wire of diameter below 4 millimeters that paint spray gun uses, and needs through more than 20 drawings step by step approximately, production efficiency is low, energy consumption is high, big for environment pollution, production cost is high.

Summary of the invention

the object of the invention is that above-mentioned traditional thermal spraying preparation method wiry is carried out technological improvement, thereby the thermal spraying wire preparation method that a kind of production efficiency is high, energy consumption is low, environmental pollution is few is provided.

Technical solution of the present invention is:

comprise feed intake melting and be cast into cylindrical bar of feed metal, hold in both hands material thereafter and be rolled into Φ 3.0～4.5mm wire rod through the rolling line machine, again with wire rod through limited drawing-die cold drawing several times, make the thermal spraying wire below the 4mm.

the invention has the beneficial effects as follows: because metal bar material is drawn into the thermal spraying wire product below the Φ 4mm again through the rolling wire rod of processing earlier; This has not only significantly reduced former cause metal bar material and has directly drawn thermal spraying drawing number of times wiry; And guaranteed not fracture of wire of drawing process; The finished silk footpath is even, and hardness is moderate, any surface finish; The production efficiency direct drawing process of tradition improves more than 40 %, also significantly reduces the times of tempering of process simultaneously, has reduced energy consumption and production cost, and has alleviated environmental pollution.

The specific embodiment

embodiment 1; The preparation of thermal spraying zinc silk: zinc ingot metal is dropped into smelting furnace; Under 570 ℃, become the cylindrical zinc of Φ 8～Φ 15mm to hold in both hands material through melting and continuous casting; Bar once is rolled into Φ 3.0～4.5mm wire rod through the rolling line machine, again with 2～5 drawing-die cold drawings of wire rod warp, promptly makes the thermal spraying zinc silk of Φ 1.2～4mm.

The bright and clean no burr of above-mentioned thermal spraying zinc silk product surface does not have greasy dirt, and is on probation through QX-1 type flame-spraying rifle: advance silk smoothly, the fuse rapid and uniform.

embodiment 2; The preparation of thermal spraying aluminium wire: aluminium ingot is dropped into smelting furnace; Under 780 ℃, become Φ 9.5～Φ 12mm cylindrical aluminium to hold in both hands material through melting and continuous casting; Bar once is rolled into Φ 3.0～4.5mm wire rod through the rolling line machine, again with 2～4 drawing-die cold drawings of wire rod warp, promptly makes the thermal spraying aluminium wire of Φ 1.6～4mm.

The bright and clean no burr of above-mentioned thermal spraying aluminium wire product surface does not have greasy dirt, and is on probation through the electric heating paint spray gun: advance silk smoothly, the fuse rapid and uniform.

embodiment 3; The preparation of thermal spraying aluminum Mg alloy wire: aluminium, magnesium ingot are dropped into smelting furnace; Under 750 ℃, become Φ 12mm cylindrical aluminium magnesium alloy to hold in both hands material through melting and continuous casting; Bar once is rolled into Φ 3.0～4.5mm wire rod through the rolling line machine, again with 2～4 drawing-die cold drawings of wire rod warp, promptly makes the thermal spraying aluminum Mg alloy wire of Φ 1.6～4mm.

The bright and clean no burr of above-mentioned thermal spraying aluminum Mg alloy wire product surface does not have greasy dirt, and is on probation through QX-1 type flame-spraying rifle: advance silk smoothly, the fuse rapid and uniform.

embodiment 4; The preparation of thermal spraying capacitor Zinc-tin alloy silk: zinc, tin slab are dropped into smelting furnace; Under 350 ℃, become the cylindrical Zinc-tin alloy of Φ 10～Φ 13mm to hold in both hands material through melting and continuous casting; Bar once is rolled into Φ 3.0～4.5mm wire rod through the rolling line machine, again with 2～5 drawing-die cold drawings of wire rod warp, promptly makes the thermal spraying capacitor Zinc-tin alloy silk of Φ 1.2～4mm.

The bright and clean no burr of above-mentioned thermal spraying capacitor Zinc-tin alloy silk product surface does not have greasy dirt, and is on probation through the electric heating paint spray gun: advance silk smoothly, the fuse rapid and uniform.
