Abstract
The invention provides a novel production method for achieving large-scale production of small-diameter flux-cored wires. According to the novel method, a rolling diameter-reducing and diameter-equalizing shaping (or micro diameter-reducing shaping) method is used for replacing a common stretching diameter-reducing method. Due to the fact that rolling deformation avoids wire breakage caused by large local deformation in stretching deformation, under the conditions that the same steel strips and the same flux core components are used and the flux powder filling rate is unchanged, the diameter of a finished wire can be smaller than 1.6 mm and even be smaller than 1.0 mm. The novel method can be used for producing various flux-cored wires. The flux-cored wires can be iron-based flux-core wires (various kinds of carbon steel and alloy steel), or nickel-based flux-cored wires, or copper and copper alloy flux-cored wires, or aluminum and aluminum alloy flux-cored wires, or zinc and zinc alloy flux-cored wires or various wrapped flux-cored wires composed of various mixed materials.
Description
Technical field
The present invention relates to a kind of flux core welding wire manufacture method, the superiority of this method is: under the prerequisite ensureing required flux cored filler rate, and it can be produced diameter and be less than the flux-cored wire that 1.6mm is even less than 1.0mm, and can realize large-scale mass production.
Background technology
Compared with solid welding wire, the advantage such as flux-cored wire has that welding production efficiency is high, welding cost is low, welding wire and layer composition are easily adjusted flexibly, can meet various production and quality requirement.In welding process, the deposite metal thing distribution of flux-cored wire is more more even than solid welding wire, and heat has a very wide distribution, and outside transmission speed is fast, and thermograde is little.Use flux-cored wire, can also reduce because heat concentrates the matrix caused to burn penetration phenomenon.These features of flux-cored wire, also limit its use occasion and welding position, in overhead welding with vertical position welding, particularly use difficulty comparatively large, the flowing of wayward deposite metal thing and distribution.The less flux-cored wire of diameter is used to contribute to breaking through these restrictions.Flux-cored wire diameter majority common on market is 2.8mm or larger, only has minority flux-cored wire can accomplish the diameter of 1.6mm.The technological difficulties of producing small diameter medicine core welding wire are that the diameter of small diameter medicine core welding wire reduces simultaneously, and its foreskin thickness is also restricted, and this directly causes its medicinal powder filling rate and is restricted.When medicinal powder filling rate is increased to certain numerical value, because its foreskin is excessively thin, in process of production, be easy to the phenomenon that fracture of wire occurs, this makes the performance of welding wire and layer all can be subject to negative effect.So the flux-cored wire producing the minor diameter meeting performance requirement is very difficult, produces the minor diameter wear-resisting welding wire with flux core with desirable anti-wear performance and be then more added with challenge.
The production method of existing flux-cored wire and the production method basic simlarity of solid silk material, mainly comprise roll forming, rough tube reducing, carefully draw tube reducing, last finish draw finished product.Add annealing break because solid welding wire can adopt, the finished silk material that plasticity is good, impurity content is few can draw the diameter being deformed to submillimeter level, even micron-sized finished product.And flux-cored wire is owing to filling the existence of medicinal powder, for avoiding the bonding between powder particle and forming continuous low-resistance medicine core, the method utilizing annealing to improve deflection can not be applied in the production of flux-cored wire.Because medicine core powder is discontinuous, the distortion of flux-cored wire concentrates on the tube wall of outer foreskin.The flux-cored wire of corresponding 1.6mm diameter, the pipe thickness of foreskin only has about 0.2mm usually.In wear-resisting welding wire with flux core tube wall, include the core particle of high rigidity.Once the local deformation of hard particles or impurity induced tube wall or stress are concentrated, flux-cored wire will be pulled off.Welding wire majority common on market is that diameter is greater than 2.8mm[CN101402161B: a kind of flux-cored wire of abrasive wear, and Sun Junsheng etc. apply for 2008].Equipment design and manufacture is also most demands [CN202877288U: a kind of roll for the production of diameter more than 2.0 flux-cored wire, Li Mingjun etc. apply for 2012] for production major diameter welding wire.In order to produce the flux-cored wire of minor diameter, usually have to sacrifice medicinal powder filling rate, the wlding capability and performance [CN102974956B: a kind of flux-cored wire, Liu Yushuan etc. apply for 2012] that directly infringement is final.For these features that flux-cored wire is produced, the present invention proposes a kind of new flux-cored wire production method, is less than the flux-cored wire of 1.6mm in order to preparation and production diameter.Under the condition of equal steel band and medicinal powder, originally minimum diameter is the flux-cored wire of 1.6mm, the new method that application the present invention proposes, and is out of shape further, makes minimum diameter and be less than 1.6mm, be even less than the flux-cored wire of 1.0mm.
Summary of the invention
The technical problem to be solved in the present invention is: the manufacture method providing a kind of flux core welding wire.When its energy manufacture diameter is less than the flux-cored wire of 1.6mm, by the coating material wall thickness control of flux-cored wire in thinner level, to ensure required flux cored filler rate and final layer properties of product.
The technical solution adopted for the present invention to solve the technical problems is: after mild-carbon steel strip is cut to suitable width, is cleaned by high temperature ultrasonic ripple, removes surface blot, oil stain etc.; Again the steel band that pretreatment is good is rolled into U-shaped.Utilize crawler type powder adding device to be added in U-shaped steel tank by the medicinal powder of required filling, then mild-carbon steel strip is rolled into O type.By the continuous acceleration drawing of drawbench, diameter is decreased to about 3.2mm-2.8mm.Silk material after tube reducing, then by milling train, making a material sectional area be further reduced to equivalent diameter to the cross section of 1.6mm – 1.0mm or less is oval silk material.Again by drawbench, allow a material accelerate through one or more shaping circular hole close to constant speed or trace, thus obtain uniform ultra-fine flux-cored wire silk material.According to composition and the mechanical property of steel band, in last shaping stretches, a small amount of distortion can be applied, make the surface of finished product welding wire more smooth, and obtain the well-regulated circular cross section of tool.Concrete preparation flow as shown in Figure 1.
In the above description, be with the citing of mild steel steel band, to facilitate explanation.Other alloyed steel strip, or other metal and its alloy, comprise Al and Alalloy band, Copper and its alloy band, nickel and nickel-base alloy band, zinc and zinc alloy band etc., are also all useful in method involved in the present invention.After band is rolled into O type, tube reducing deformation method can have following selection.Can be that rough tube reducing is to certain diameter; Also can be to certain diameter with rolling tube reducing; Can also be that the combination of two kinds of deformation methods realizes tube reducing to certain diameter.
The invention has the beneficial effects as follows: for the production of the smelting impurity inevitably containing certain size and certain statistical magnitude in the steel band of flux-cored wire, harder medicine core powder particle is also bound to cause the local deformation of welding wire tube wall after tube reducing.In drawing tube reducing process, they all can bring out the inefficacy distortion under tensile stress, and namely flux-cored wire is pulled off before finished product.In the present invention, we adopt rolling reduction to replace stretching mode to realize the tube reducing of flux-cored wire.In roll compacting stress field, distortion of losing efficacy is less likely to occur the weak-strong test containing impurity or local deformation, avoids welding wire to be pulled off, realizes the silk material tube reducing larger than drawing mode.So, apply method of the present invention, wire diameter thinner medicine core wlding can be prepared, the comprehensive welding potential of exploitation flux-cored wire.
