Summary of the invention
Its purpose of the present invention just is to provide a kind of pre-stressed galvanized steel strand production process; this process using zinc-plated polishing, do not shut down joint, optimize drawing, zinc-plated stabilisation production technology; can improve lumber recovery; reduce production costs, make product reach high strength, high toughness plasticity, high antiseptic property, underrelaxation, low deflection drawing coefficient, linearity is good.
Technical scheme of the present invention is: a kind of pre-stressed galvanized steel strand production process, little alloy high-carbon wire rod-pickling-high pressure flushing-middle temperature phosphating-rinsing-saponification-oven dry-rotation unwrapping wire-1200mm reel 9 passage continuous pressures rotation mould drawing-1400mm I-beam wheel take-up-zinc-plated unwrapping wire-degreasing-cascade sealing pickling-complex salt help the blue frame take-up of plating-electric furnace oven dry-galvanizing-surperficial erasing-cool off-spend-scalable spend blue frame unwrapping wire-zinc-plated light whole-I-beam wheel take-up-seven piece pools capital-aligns the-the first tensioning-removable heating in medium frequency-cooling-second tensioning-retractable cable-traction-layer around bundling-packing-warehouse-in.
Compared with prior art the present invention has the following advantages:
1, since this process using zinc-plated polishing, do not shut down joint, optimize drawing, the zinc-plated production technology of changing surely; thereby product to have high strength, high tenacity, high antiseptic property, linearity good, have economical with materials, prolong product service life, characteristics such as easy construction.
2, adopt homemade wire rod to substitute the import wire rod, can save production cost 30%, shorten 3 months materials procurement cycles.
3, optimization production technology and new technology can improve lumber recovery more than 3%, have reduced production cost more than 7%.
The specific embodiment
Embodiment
Comprise little alloy high-carbon wire rod-pickling-high pressure flushing-middle temperature phosphating-rinsing-saponification-oven dry-rotation unwrapping wire-1200mm reel 9 passage continuous pressures rotation mould drawing-1400mm I-beam wheel take-up-zinc-plated unwrapping wire-degreasing-cascade sealing pickling-complex salt help the blue frame take-up of plating-electric furnace oven dry-galvanizing-surperficial erasing-cool off-spend-scalable spend blue frame unwrapping wire-zinc-plated light whole-I-beam wheel take-up-seven piece pools capital-aligns the-the first tensioning-removable heating in medium frequency-cooling-second tensioning-retractable cable-traction-layer around bundling-packing-warehouse-in.
Described wire drawing passage 9 passages, drawing speed 3～6m/s, 380～450 ℃ of debinding furnace temperature, pickling concentration 15～25% helps 60～80 ℃ of plating temperature, 430～460 ℃ of zinc-plated temperature, zinc-plated speed 13～18m/min; Stabilization processes tension force 40～50%F
b, 360～400 ℃ of heating in medium frequency temperature, stabilization processes speed 50～80m/min.
The present invention carries out mechanical property, chemical analysis check with the homemade microalloy high-carbon wire rod that buying comes before entering factory, wire rod after the assay was approved changes the pickling workshop over to and carries out pickling, remove the wire rod scale on surface, utilize high pressure water washing that the dirt and the residual acid on wire rod surface are rinsed well again, enter then and carry out phosphatization in 80-90 ℃ the phosphatization liquid and handle, make wire rod surface form that one deck is high pressure resistant, the phosphatization mould of high temperature, then enter saponification and oven dry is handled.Wire rod after surface treatment is good enters drawing plant, by rotation pay off rack unwrapping wire, pulls out through 9 road pressure die drawings at the reel of big format diameter 1200mm, and the wire drawing admission machine adopts the take-up of major diameter 1400mm I-beam wheel.Steel wire drawing back steel wire well changes zinc-plated workshop unwrapping wire over to, by the degreasing of debinding furnace high temperature, then through cascade sealing pickling, remove the Steel Wire Surface iron scale, then help plating by the quickening liquid of forming by complex salt, through galvanizing again after the electric furnace oven dry, zinc-plated back steel wire is through water-cooled, air-cooled, by spending blue frame take-up; Zinc-coated wire is hung on extension type paying out machine unwrapping wire, by the polishing machine zinc-coated wire is carried out polishing processing, strength of galvanized wire is obviously improved, the better quality of zinc laminar surface improves zinc-plated antiseptic property, improves the zinc-coated wire dimensional accuracy.Zinc-coated wire after polishing processes enters for seven one group and carries out twisting in the buncher, galvanized strand wires behind the plying is aligned through straightener, form tension force by first regulating wheel, second regulating wheel again, by the packaged type intermediate frequency furnace galvanized strand wires being carried out heating in medium frequency simultaneously handles, eliminate the residual stress of steel strand wires inside, inner dislocation structure is stable, steel strand wires are handled through water cooling more afterwards, around last admission machine, draw to layer winder through the rubber tyre traction wheel and carry out bundling, the galvanized strand wires after inspection by sampling is qualified is packed warehouse-in.
The homemade microalloy high-carbon wire rod of this process using, big specification wire drawing machine, big specification admission machine, the drawing of pressure mould rotating mould; effectively improve steel wire surface quality and obdurability, help plating, novel strand system guide wheel, stabilization temperature warning, novel bipyramid face self-locking tensioner cover, zinc-coated wire table by not shutting down joint, plating leakage warning, double pump spray, complex salt
New technologies such as flour dirt cancellation element have improved obdurability, relaxation property and the antiseptic property of product.
