Characteristics of advanced wire rod mills
- Production speeds up to 120 m/s
- Utilization factor up to 90 % and more
- Yield of material over 96 %
- Good tolerances and minimum surface scratching to achieve best prices in the markets
- Temperature control system throughout the mill to achieve repeatable and uniform material properties :
- Rolling within closed temperature ranges meeting the particular material demands
- Low temperature rolling
- Controlled cooling process used as in-line heat treatment or for “pre-adjustment” of material properties
- Low labour cost due to high degree of automation
- Extensive program system for both the rolling process and subsequent rod treatment
- Developed and improved continuously, including the experience and expertise gained from many
- Rolling mills delivered by Rana Udyog
- An effective tool to save costs in downstream processes and achieve an optimal product structure and specific Physical properties
Intermediate cooling upstream the rod mill block
- Maintain the desired temperature field by regulating the water pressure
- Temperature controlled rolling possible
- Improved grain size(fine) of rolled material
- Quick-acting valves for higher speeds and small-diameter rod to shut off the water flow while the rod head end enters the cooling pipes.
- Cooling line also suitable for other products
- High strength values:
| • Yield point : |
500 N/mm2 |
| • Tensile strength: |
560 N/mm2 |
| • Elongation percentage grade: |
12% |
- Other data:
| • Final rolling temperature: |
950-1050°C |
| • Equalizing temperature at laying head: |

Ring conveyor with air cooling
- Adjustable speed to influence package compactness by varying ring overlapping patterns
- Steps within the conveyor and provision for change of roller groups speed to change overlap position
- Suitable for retarded and accelerated cooling
- Consisting of three sections
- Ring laying section
- Secondary cooling train for controlled cooling
- Delivery section to reforming tub
Controlled cooling section
- Retarded cooling for cooling rates of less than 0.3 K/s
- Accelerated cooling for cooling rates of more than 25 K/s
- Air flow rates at the loops of more than 50 m/s
