Production line and factory setup overview
A small/medium heat-treatment and converting line producing soft black binding wire from purchased hard-drawn low-carbon wire through coil receiving and chemistry/diameter inspection, controlled recoiling into furnace-compatible carriers, batch loading, oxygen-limited pot or bell annealing, programmed heating/soak/cooling, unloading and oxide inspection, tensile/elongation and bend testing, rewinding into merchant coils or cutting into tie bundles, weighing, packing and lot traceability. Drawing wire rod, pickling and galvanizing are separate upstream scopes.
Recommended lowest-entry line configuration For the lowest credible entry, buy hard-drawn SAE1006/1008-class wire at one diameter, typically 1.0-1.6 mm, and install one supported oxygen-limited batch pot/bell furnace with furnace carriers, controlled thermocouples and recorded recipes, plus recoiler, merchant-coil rewinder or straight-cut/bundle cell and tensile/elongation tools. Do not buy a complete 5.5-8 mm wire-rod drawing line until scale, descaling and several hundred kilowatts of power are justified.
Production process and implementation sequence
- Hard-drawn wire receiving and release
- Controlled recoiling onto furnace carriers
- Batch identification, loading and thermocouple placement
- Oxygen-limited heating and soak
- Controlled furnace cooling
- Unload, descale/clean only as specified
- Rewind coils or straighten/cut tie lengths
- Mechanical test, weight, pack and trace release
Products, capacity and market fit
- Construction crews need soft, consistent wire for tying reinforcement without brittle breaks.
- Buying hard-drawn wire avoids a high-power drawing/descaling line at entry.
- Batch annealing can serve one diameter while local demand and furnace utilization are proven.
- Annealing atmosphere, temperature uniformity and controlled cooling govern softness and scale.
- Black annealed binding-wire coil - One diameter, tensile-strength range, elongation, bend softness, coil mass, surface/scale and oil limits - Rebar contractors and building-material merchants
- Pre-cut tie-wire bundle - Same released wire cut to one buyer length with count/mass and safe ends - Construction crews seeking ready-to-use ties
