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

Multi Stand Slit Rolling

The dogbone, slit, finishing stands rolled through ‘Size Stabiliser Housing less Stands’, through multi strand ‘Controlled Cooling Bar Tempering system’, cut by ‘Wide Blade Flying Shear’ conveyed & braking through ‘ Lifting Apron Type entry roller table & ‘ Walking Beam Cooling Bed’ with inbuilt ‘Layer transfer system’

Advantage

• 15% Power saving for slit sizes, since the cross section area rolled is in multiple of strands.

• (Furnace capacity 16/20 TPH)

• Fuel saving, as the furnace discharge temperature can be reduced by 40degC, as speed of rolling in roughing & intermediate stands is higher, the material gets heated during rolling.

• Four nos. less nos. of total stands for four slit, Less roll consumption per ton.
