The invention relates to a continuous heat processing technology of a steel wire, which is characterized in that the steel wire penetrates into a heat processing heating furnace for heating by a pay-off rack, penetrates into a lead pool for lead quenching, penetrates into a pickling tank for pickling, then penetrates into a parkerising pool, penetrates into a saponification pool, penetrates through a drying box and finally is wound up. The continuous heat processing technology of the steel wire in the invention has the advantages that a continuous heat processing line is used, the pickling and parkerising are carried out in a mode of one line, and a steel wire technology for each specification can be adjusted by adjusting speed of the steel wire heat processing, thus reducing production cost and improving production efficiency; and all processing procedures are linked compactly; and weight of parts is improved to reduce joint number in the steel wire so as to improve quality of the steel wire.
Description
Technical field
The present invention relates to a kind of continous way thermal treatment process of steel wire,
Background technology
Steel wire is one of plate, pipe, type, silk four big kinds of steel, is through the cold drawn reprocessing product of processing with gren rod.The master operation of Production for Steel Wire comprises material choice, removes iron scale, oven dry, coating processing, thermal treatment, wire drawing, coating processing etc.
Thermal treatment comprises 3 types of raw material thermal treatment, intermediate heat treatment and finished product thermal treatments.Intermediate heat treatment is to be the thermal treatment that the mid-line base carries out to the steel wire work in-process, and main purpose is to eliminate the work hardening that produces in the Cold Drawing Process, and the plasticity of recovery lines base is beneficial to further drawing.Like no finished product heat treatment step in producing, then end product drawing preceding in ask that thermal treatment also requires tissue and the performance of guaranteeing that the finished product steel wire should have.Intermediate heat treatment is used the intermittent type wire heat treatment process, and promptly first thermal treatment is carried out surface acid-washing again and handled; Carrying out alramenting again handles; Carry out surperficial saponification again and handle, undesirable but this Steel Wire Heat Treatment operation connects, production efficiency is low; Tank farm stock is big between operation and the operation, and production cost is high; Thermal treatment part anharmonic ratio is less, usually less than 200KG/ spare, there is certain influence in the quality of wireline finished product.
Summary of the invention
In order to address the above problem, the invention provides a kind of continous way thermal treatment process of steel wire, improved the linking ability between the operation through this continous way thermal treatment process, improved production efficiency, reduced production cost.
In order to address the above problem, the invention provides a kind of continous way thermal treatment process of steel wire,
Technical scheme of the present invention is:
A kind of continous way thermal treatment process of steel wire is used the continous way heat-treatment lines, pickling, line of phosphatization,
May further comprise the steps:
(1) process furnace heating: steel wire is through the pay off rack unwrapping wire; Penetrate in the heat treatment heating furnace; In process furnace, heat through 970～990 ℃ one section heating, 920～940 ℃ of soaking zones; Wherein between one section heating and soaking zone heating, 950～970 ℃ two sections heating, 935～955 ℃ of three sections heating are arranged, be 2-3min heat-up time;
(2) lead is quenched: the steel wire through the process furnace heating penetrates plumbous pond, carries out lead through 545～555 ℃ fused lead and quenches, and the lead time of quenching is 0.5-1min;
(3) pickling: penetrate pickling tub through the plumbous steel wire of quenching, use hydrochloric acid to carry out pickling, the pickling time is 1.5-2.5min;
(4) phosphatization: the steel wire through overpickling penetrates the phosphatization pond, uses phosphoric acid salt to carry out phosphatization, and phosphating time is 1.5-2.5min;
(5) saponification: the steel wire through phosphatization penetrates the saponification pond, carries out saponification;
(6) oven dry: dry through drying baker through the saponified steel wire, 200～250 ℃ of bake out temperatures, drying time are 0.3-0.8min, last take-up.
The purpose of pickling is in order to remove iron scale; Remove the iron scale on wire rod or mid-line base surface; Iron scale damage mould and Steel Wire Surface when preventing drawing are coated with or friction that coating is handled when preparing the surface of good condition and reducing drawing reduces drawing force for follow-up.
Wire rod or mid-line base need carry out low-temperature heat and promptly dry in order to remove hydrogen and moisture after chemical de-scaling and coating are handled, general 300 ℃ of bake out temperature, and temperature is unsuitable too high, in case the slip coating inefficacy.Dehydrogenation is promptly got rid of the hydrogen of in acid cleaning process, invading in the base steel, and purpose is an elimination of hydrogen embrittlement, recovers the plasticity of wire rod, removes the moisture on wire rod surface, makes it dry, prevents that moisture from worsening the result of use of lubricant.Drying equipment commonly used has 3 kinds: drying baker, tunnel like stoving oven and chain type stoving oven, drying baker are the casing that has loam cake, and it is definite that its effective dimensions press the maximum diameter of drum, pass to 150～250 ℃ hot blast during work in the case.This equipment drying rate is very fast, and the time is about 2～15min, dries more even.
Beneficial effect of the present invention is: use the continous way heat-treatment lines; Pickling, line of phosphatization; Speed through regulating Steel Wire Heat Treatment is regulated each specification wire technology, has reduced production cost, has improved production efficiency; Linking between the treatment process is tight, heavily reduces the joint quantity raising wireline quality in the wireline thereby improve part.
