Description
Technical field
The present invention relates to a kind of steel bead wire preparation method, adopt the steel wire of present method preparation to be widely used in underloading and radial tyre of passenger car and bias tire.。
Background technology
Along with the development of automotive light weight technology, high speed, as the radial of automobile important component part, obtain rapidly application and development with advantages such as its high speed, energy-saving, lightweight, actual service life length.Radial in use will bear stretching, compress, reverse and the reactive force such as centrifugal, as the steel bead wire of one of framework material, and the good and bad quality that directly affects tire of quality.
In traditional production process, use lead bath that steel wire is carried out quench treatment, because the rate of cooling of patenting is far above water quenching, so easily form in process of production a small amount of troostitic structures.Because troostitic structures sheet spacing is very little, so the obstruction of On Dislocation Motion is large, the plastic deformation resistance increases, thereby is unfavorable for the follow-up cold working of steel wire.Plumbous mist in the production process also can cause to a certain degree injury to human body in addition.
Therefore, there is defective in prior art, needs to improve.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of steel bead wire preparation method for above-mentioned deficiency of the prior art exactly, the number of drawbacks and the deficiency that exist to solve existing employing technology.
Realize the technical measures of above-mentioned purpose:

Adopt technical scheme of the present invention, owing to adopt lead bath quenching technique, in actual mechanical process, be not easy to form and be unfavorable for the follow-up cold worked troostitic structures of steel wire, and pollute littlely, can not bring to operator the source of pollution of the harmful to human such as Lead contamination.
Description of drawings
Fig. 1 is a kind of steel bead wire preparation method of the present invention schema.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention are made more explicit defining.
Embodiment one
As shown in Figure 1, for solving the problems of the technologies described above, the invention provides a kind of water quenching sorbitizing steel bead wire preparation method, by the deficiency that adopts present technique to exist to solve above-mentioned traditional patenting technology.This patent is achieved in that
Hardening liquid by adding macromolecule polyacrylic acid sodium to improve the viscosity of water, strengthens the surface tension of the aqueous solution by 96% sodium polyacrylate and 4% soft water preparation.Steel wire in hardening liquid by austenite structure to the sorbite structural transformation, this metaplasia drag is large less than troostite, has good comprehensive mechanical performance.
Embodiment two
On the basis of above-described embodiment, after steel wire was processed through the water quenching sorbitizing, its mechanical property obviously was better than traditional patenting and processes.Take the 1.30NT steel bead wire as example, relative reduction in area is higher by 4% than patenting after the water quenching, and its twisting property is higher about 3-5 time than patenting.
Embodiment three
On the basis of above-described embodiment, a kind of steel bead wire preparation method is provided: A is with the steel bead wire unwrapping wire;
The thermal treatment of B direct-fired heater; By with steel wire heating, so that steel wire satisfies condition, the steel wire interior tissue changes to austenitizing.(Ao Shitihua ﹠amp; Quenching is in order to obtain being fit to the tissue of postorder drawing) when silk is heated to the Ac1 temperature, as when being heated in the 820-860 degree centigrade of scope, perlite is just to austenitic transformation, because of perlite to austenitic transformation, that inner composition differs greatly, lattice is different, and two-phase mixture is transformed into the former process of single phase solid solution.Therefore, transition process must be carried out the redistribution of carbon and lattice reorganization, and the two only has by atom and diffusion and just can finish.
C: adopt the fuel oil direct-fired heater, traditional retort furnace DV value is low, and the DV value refers to process the product of steel wire quantity and diameter.Retort furnace horse not hole is easily stopped up, and affects production efficiency.And adopt fuel oil direct-fired heater atmosphere good, steel wire is difficult for oxidation, adopts pressure-fired to process.
D carries out water quenching in hardening liquid; So that the steel wire tissue is changed to sorbitizing by austenite.
E carries out water cooling, and how temperature when entering pickling by regulating water flow with the control steel wire namely controls pickling temperature.It is large that hydrochloric acid is crossed the peracid consumption, crosses the low pickling quality that affects.
F carries out pickling; Thermohaline pickling in the employing, temperature are removed the oxide compound that Steel Wire Surface is residual about 45-55 ℃.The employing white oil covers, and white oil buoyancy is large than hydrochloric acid, floats on the hydrochloric acid top, can effectively prevent the acid mist volatilization, and Reduction of acid consumption also reduces personal injury.
The residual acid solution of steel wire is cleaned in G water flushing, prevents that acid solution from bringing Phosphating Slot into and affecting the phosphatization quality.
H carries out phosphating reaction, the iron-based of steel wire and Phosphating Solution during phosphating reaction (are mainly Zn (PO4) 2 dilute aqueous solns and an amount of free phosphoric acid and accelerator etc., the effect of the low phosphatization temperature of the main landing of accelerator and quickening phosphatization speed, as chemical accelerator oxygenant with the most use such as NO3-, NO2-, CIO3-, H2O2 etc.), and add cupric nitrate promotion Phosphating Solution in the Steel Wire Surface film forming, phosphatize phosphate coat is conducive to the drawing of steel wire postorder, and has certain antirust ability.It is between the 11-13 that total acidity is controlled at pH value, and the too high sediment of total acidity is more, the more difficult cleaning of waste and sediment, total acidity reaction steel wire phosphatization speed.
I neutralizes, and is mainly NAOH, because the preorder acid washing phosphorization is processed, it is acid that Steel Wire Surface is, and is unfavorable for postorder butt welding processing, and the acidic surface easy-to-rust.
J carries out take-up.
In the preferred aforesaid method, hardening liquid is by 96% sodium polyacrylate and 4% soft water preparation.
Above embodiment is more preferably one of embodiment of the present invention, and common variation and the replacement of those skilled in the art in the solution of the present invention scope all should be included within protection scope of the present invention.
