Slit Rolling Mill
Slit Rolling Mill
Slit rolling configurations are offered to increase output of small-diameter TMT bars while making full use of reheating capacity. Using dog-bone pass designs and slit passes, multiple strands are rolled through housingless finishing stands, followed by controlled cooling, flying shears, and walking-beam cooling beds.Typical Advantages:
- Significant power savings for slit sizes
- Fuel savings through reduced furnace discharge temperature
- Reduction in total number of stands and rolls required
