Background technology
High-strength galvanized steel wire, because of its mechanical property with excellence and good antiseptic power, is widely used in the important events such as bridge cable, suspension cable.High-strength galvanized steel wire is with high-carbon pearlitic steel wire rod for raw material, first pass through multi-pass continuous cold drawing deformation and obtain extra-high strength wire, then carrying out galvanizing by dipping process again, the hot galvanized layer obtain continuously in Steel Wire Surface, being well combined, thus obtaining good decay resistance.
Owing to Mechanism of High Strength Pearlite Steel Wire is through large deformation amount plastic deformation, deformation storage energy (mainly existing with the form such as residual stress, high density dislocation) that its internal existence is higher, heating process is extremely sensitive.In the hot galvanizing process of steel wire (zinc-plated temperature is typically in 440 DEG C～460 DEG C, and the time is 20 seconds～40 seconds), will there is a series of change in the residual stress of high-tensile steel wires, dislocation etc..Owing to Steel Wire Surface directly contacts about 450 DEG C liquid Zn, and inside needs to can be only achieved same temperature through heat transfer, owing to the zinc-plated time is short, the heating process frequently resulting in Steel Wire Surface and internal experience is inconsistent, causing that more uniform residual stress can become skewness originally, macro manifestations is steel wire torsion performance dramatic drop-off.
At present, adopt the bridge cable high-strength galvanized steel wire that domestic high-carbon steel wire rod produces, the index that can not meet standard-required is mainly hot-dip galvanizing steel wire (standard sample, length is 100d, d-steel wire diameter) the torsion number of turns enclose (be typically in 3～11 circle) lower than 14, and high-tensile steel wires zinc-plated before the torsion number of turns be generally attained by more than 25 circles.The torsion index of bridge cable high-strength galvanized steel wire becomes the key factor limiting domestic high-carbon steel wire rod large-scale application.

Described high-carbon steel pearlite wire rod is free of surface defects, and metallographic structure sorbite rate more than 90%, wire rod intensity is between 1200MPa～1350MPa.
Hot blast or high pressure steam heating is adopted when described lonneal processes.
Zinc-plated temperature is 440 DEG C～460 DEG C, and the zinc-plated time is 20s～40s.
Stabilizing treatment, adopts heating in medium frequency, and temperature is chosen as 380 DEG C, and the time is 20s～30s.
The bridge cable zinc-coated wire of 1770MPa～1960MPa level of described finished product zinc-coated wire Ф 5～Ф 7mm, reverses the number of turns >=14.
Beneficial effect:
1) the bridge cable zinc-coated wire of 1770MPa～1960MPa level that this technique is applicable to Ф 5～Ф 7mm produces.Original wire rod can be selected for domestic high-quality high-carbon steel wire rod；Compared with the prior art, technique is changed little.
2) twisting property is stable: as long as reversing the number of turns >=20 circle before cold drawing wire galvanization, adopt the technology of the present invention cross high-tensile steel wires zinc-plated before carry out lonneal process after, it is ensured that the torsion number of turns >=14 of high-strength galvanized steel wire circle.
