Services of thermal treatment of wire and wire rod
The annealing processes are carried out in a bell-type furnace, in N2 protection gas.
Types of processes:
- Spheroidising annealing of wire rod and wire for upset forging and cold extrusion (+AC)
- Recrystallisation or softening annealing of wire rod, low-carbon wire and low-alloy wire (+A)
- Complex service including annealing and preparation of wire rod surface for drawing by means of pickling and applying a carrier coating (lime, phosphate, reactive soap)
Recommended charge:
- External diameter of coil - max.1250 mm
- 6 t of wire rod (3 racks): 3 x 2t or 3 x (2x1t)
- Internal diameter of coil - min. 800 mm
- Charge height (on a rack, including the instrumentation) - 1500 mm
or
- External diameter of coil - max.900 mm
- 12 t of wire (7 racks):
- Internal diameter of coil - min. 350 mm
- Charge height (on a rack, including the instrumentation) - 1700 mm
