Route map
What happens to a coil between the day it arrives from the mill and the day it leaves as bright wire.
- 01
Receive
Wire rod from primary mills, tagged by heat.
- 02
Acid pickling
Mill scale off, phosphate coat on — the surface is prepared for the die.
Details - 03
Bell furnace
A long, controlled heat-and-cool cycle that re-arranges the steel from the inside.
Details - 04
IVD wire
Cold-drawn through carbide dies to the final diameter, with a bright finish.
Details - 05
Dispatch
Coils tagged with grade, size and heat.
Stage 01 · Surface
Acid pickling & phosphating
Hot-rolled wire rod leaves the mill covered in mill scale — a hard, brittle layer of iron oxides formed as the red-hot rod cools in air. Drawn as it is, that scale would tear the carbide dies and score the wire. So before anything else, each coil is chemically cleaned and given a coating that will carry lubricant into the die.
Stage 02 · Structure
Bell furnace annealing
Annealing is the stage you cannot see in the finished wire — and the one that decides how it behaves in your press. In an electrical bell furnace, a charge of coils is heated, held and slowly cooled. The cycle softens the steel, relieves stresses from rolling and drawing, and for alloy and higher-carbon grades changes the shape of the carbides inside.
Stage 03 · Size
IVD wire drawing
Drawing is where rod becomes wire. The coil is pointed, threaded through a tungsten-carbide die and pulled by a powered block. The die is slightly smaller than the rod, so the steel is stretched and squeezed to a new, precise diameter. On our inverted vertical drawing (IVD) machine, the finished wire drops into a coil beneath the block — suited to heavy coils and larger sizes.
