Abstract
The invention discloses a steel wire heat treatment process. A steel wire is paid-off through a pay-off rack, natural gas is used for directly heating the steel wire, and then the steel wire penetrates into a quenching pool to be quenched; afterwards, the steel wire is flushed with water, penetrates into an acid pickling pool and then a phosphorization pool and then is dried through a drying oven; and finally the steel wire is wound. The whole heat treatment line is free of pollution, clean and environmentally friendly; the heat utilization rate is high and energy is saved in heat treatment.
Description
Technical field
The present invention relates to the Technology for Heating Processing of a kind of steel wire.
Background technology
Steel wire is one of the plate of steel, pipe, type, the big kind of silk four, with hot rolling dish through the cold drawn reprocessing product made.The master operation of Production for Steel Wire includes material choice, removes iron scale, heat treatment, wire drawing, surface treatment, drying etc..
At present, the Steel Wire Heat Treatment Muffle furnace burning coal that adopts, its heat treatment heat utilization efficiency is low with production efficiency more.The technology of part advanced person adopts natural gas or electrical heating, quenching technical many employings patenting technique, but can cause environmental pollution, not environmentally.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of clean environment firendly, and the Technology for Heating Processing of the high steel wire of heat treatment heat utilization efficiency.
In order to solve above-mentioned technical problem, the invention provides a kind of wire heat treatment process, complete from unwrapping wire to take-up on same one procedure, this technique specifically sequentially includes the following steps:
(1) heating: steel wire is through pay off rack unwrapping wire, during heating, uses natural gas to be heated, directly to the naked burning of steel wire；
(2) quenching: the steel wire through heated by natural gas is penetrated quenching bath, quenches through quenching medium aqueous solution, is then rinsed with water；
(3) pickling: the steel wire through quenching is penetrated pickling tube, uses hydrochloric acid to carry out pickling；
(4) phosphatization: the steel wire through overpickling penetrates phosphating pond, uses phosphate to carry out phosphatization；
(5) dry: the steel wire through phosphatization to be dried by drying baker, last take-up.
Described step (1) heats, and is divided into by heating sequence: one section of heating, two-stage nitration heating, three sections of heating, soaking zone heating；Described one section of heating heating-up temperature is 970-980 DEG C, and described two-stage nitration heating heating-up temperature is 950-960 DEG C, and described three sections of heating heating-up temperatures are 940-950 DEG C, and described soaking zone heating heating-up temperature is 920-930 DEG C, and each bringing-up section heat time heating time is 1-2min.
Described step (2) is quenched, and hardening heat is 90-100 DEG C, and the cool time is 1-1.5min, rinses temperature and is 70-80 DEG C, and washing time is 0.5-1min.
Described step (3) pickling, described pickling tube is sealed pickling tube, and its mode of heating is steam heating, and pickling temperature is 80-90 DEG C, and during pickling, described hydrochloric acid is vaporific, and pickling time is 1-2min.
Described step (4) phosphatization, phosphatization temperature is: 80-90 DEG C, and phosphating time is 1-2min.
Described step (5) dries, and dries temperature and is 150-200 DEG C, and drying time is 1-2min.
Adopting above-mentioned technique, compared with prior art, it has the beneficial effects that the present invention:
1, the present invention uses natural gas directly to the naked burning of steel wire, is heated, and uses natural gas directly to the naked burning of steel wire, and this mode of heating heat utilization efficiency is high, do not produce pollution.
2, quenching: the steel wire through heated by natural gas is penetrated quenching bath, quenches through quenching medium aqueous solution, and quenching medium aqueous solution produces air film, is wrapped in Steel Wire Surface, it is ensured that the rate of cooling of quenching steel wire.
3, pickling: the steel wire through quenching is penetrated pickling tube, hydrochloric acid is used to carry out pickling, pickling in order that remove iron scale, remove the iron scale on wire rod or intermediate line base surface, iron scale damage mould and just dead surface when preventing drawing, process friction reduction pulling capacity when preparing good surface condition and reduce drawing for follow-up painting or coating.
4, whole piece heat-treatment lines is pollution-free, clean environment firendly；Heat treatment heat utilization efficiency is high, and energy-conservation heat treatment carries out heating, surface treatment continuous lines, and production efficiency height thermal treatment quality is stable.
