Problems solved by technology

[0002] At present, the production process and technology of rare earth coated steel wire for bridge cables are still in the exploratory stage. Due to the low melting point of rare earth coating (382°C), and the temperature parameter of the traditional stable production process is 370-390°C, it is very easy to cause The rare earth coating melts; if the temperature drops too much (below 360°C), the product performance cannot meet the requirements of low relaxation and elongation

Embodiment Construction

[0013] The embodiment, as shown in the figure, includes: flower basket unwinding 1, straightening 2, first tensioning wheel set 3, smoothing die 4, intermediate frequency furnace 5 tempering, cooling tank 6 cooling, force measuring wheel 7, second Tensioning wheel set 8, traction machine 9, shearing machine 10 shear, and take-up machine 11 forms a coil.

[0014] The tempering temperature of the intermediate frequency furnace 5 is 360-370°C.

[0015] The steel wire passes through the flower basket pay-off machine 1, passes through the straightener 2, enters the first tensioning wheel group 3, enters the intermediate frequency furnace 5 for medium temperature tempering after finishing the mold 4, and then enters the cooling tank 6 for cooling, and then passes through the The force-measuring wheel 7 and the second tensioning wheel group 8 are drawn into the shearing machine 10 by the tractor 9, and then enter the wire take-up machine 11 into coils through shearing.

Abstract

The invention relates to a high-strength prestress rare earth coating steel wire stabilization production technology, which comprises the following steps: paying off by a basket, straightening, tensioning by a first tension pulley unit, finishing by a finishing module, tempering by a middle-frequency furnace, cooling by a cooling bath, force measuring by a force measuring wheel, tensioning by a second tension pulley unit, towing by a towing machine, cutting by a cutting machine and coiling by a take-up machine. The traditional temperature parameter of the stabilization is changed and is reduced by 20 DEG C, and a great amount of electric power is saved. The temperature control is stable, the fluctuation range is small, and the quality of the zinc layer on the surface of the steel wire is ensured. The tension value of the galvanized steel wire stabilization production is improved, and different mechanics performances of the product are optimized. The flexible parameter of the steel wire is remarkably improved, and particularly the torsion value of the steel wire is improved.

Description

technical field [0001] The invention relates to a stable production process of high-strength prestressed rare earth coated steel wire. Background technique [0002] At present, the production process and technology of rare earth coated steel wire for bridge cables are still in the exploratory stage. Due to the low melting point of rare earth coating (382°C), and the temperature parameter of the traditional stable production process is 370-390°C, it is very easy to cause The rare earth coating melts; if the temperature drops too much (below 360°C), the product performance cannot meet the requirements of low relaxation and elongation. Contents of the invention [0003] The purpose of the present invention is to provide a stable production process for high-strength prestressed rare earth coated steel wire, which can be suitable for the process parameters of stable production of high strength prestressed rare earth coated steel wire, and ensure the surface quality and various ...
