LOCATION The Flying is Shear placed between the Quenching Box and the Cooling Bed. APPLICATIONS To cut the T.M.T. Bar at a temperature of 500oC and above to the required lengths. FEATURES The 1000 mm CRS (adding to the manufactures cost because with 1000 mm centres the depth of the shear also has to be increased leading to increased dia gears, shaft lengths, casing weight) instead of 800 or 850 CRS so as to reduce the base rpm of the drives Motor. Since it is a start stop shear the motor shall have to accelerate to lower (base) rpm hereby reducing power consumption on recurring basis and generate payback. The casing is prestressed to prevent seperating of casing parting surfaces on load during the milli seconds when the cut is executed. The cutter ends are involute profiled at ends. The cutters engage before the bar touches the cutting edge, eliminating possibility of erroneous blade over lap. We provide an optional arrangement of Flywheel with mechanical clutch. The flywheel is engages for cutting above 20 mm bar size. The flywheel inertia augments the lower power available from constant torque motor running at low rpm to match thicker bar rolling speed. The casing front end and pinch roll cantilever shaft is water cooled to avoid distortion with heating. The gears are case carburised hardened & ground designed for minimum back lash. Again the gears and knife holders are designed for minimum intertia.

Double helical gear has both left- right helical teeth, is used to balance the thrust force and provide additional gear shear area. Also known as Herringbone gears, which resemble two helical gears that have been placed in an adjacent manner. Being double helicals, the thrusts are counter-balanced with no thrust loading on the bearings. FEATURES Teeth grinded on hofler gear grinder, mot is checked post operation, surface finish, geometrical accuracy, contact with the mating part are checked, 70%, backlash is checked whether it is within the limits. Apex is checked in case of shrink, distance between two gears is checked, and material is 18crnimo6. Gear quality –Din1 and Din 2 Teeth cutting on hobbling operation maintaining the teeth grounding allowance. Gear machined using tools and inserts from world’s best tool manufacturer like seco and sandvik Sharpening of gear cutters done on German machine klingenberg sharpener Grinding is done on cnc gear grinder using grinding wheels of Winterthur APPLICATION Heavy machinery External gear pumps Required on higher pressures & larger percentage of filled materials TECHNICAL SPECIFICATION: These gears are placed in V shape as two mirrored helical gears joined together. The mirrored arrangement revokes net axial thrust as each half of gear thrusts in opposite direction. To operate in rotational directions, these gears are extended in two possible arrangements for oppositely oriented helical gears/gear faces, one stable and the other unstable.

LOCATION The Disc & Drum Shear is placed between the Roughing and intermediate Mill. APPLICATION To Cut the front and back end of the squares upto 32 mm at 900o C In case of misroll at the Intermediate or Finishing Mill the deviator pipe is shifted directing the bar to the Drum Shear which cuts It into scrap pieces ADVANTAGES In the mills the Snap Shears are mounted on repeaters to cut the bar in case of misroll, but the bar which is coming from the Roughing Mill is continuously fed into the mill is getting entangled on the roll. This feeding of the bar is stopped by cutting at the Drum Shear, thereby drastically reducing the down time of the mill in case of misroll. FEATURES Both Disc & Drum Shear are with case carburised, hardened & ground gears, (almost eliminating teeth wear) with near zero backlash. The cut pieces at the Drum Shear are collected in a tray placed under the silo, keeping the surrounding clear and enabling easy removal

LOCATION The Crank Shear is placed between the Roughing train & the Intermediate train. APPLICATIONS To cut front/back end & Cobble cutting of the square at a temperature of 900 deg C and above. FEATURES The casing is prestressed to prevent seperating of casing parting surfaces on load during the milli seconds when the cut is executed. The cutter ends protrude, so as to have increased blade grinding margin. We provide two nos. Flywheels with mechanical clutch. The additional flywheel has to be engaged for cutting heavier section. The flywheel inertia augments the power available for cutting from constant torque motor. The casing front face is water cooled to avoid distortion with heating from moving rolled stock. The gears are case carburised hardened & ground designed for minimum back lash. Again the gears and knife holders are designed for required intertia. ADVANTAGES The square shaped cobble cutting is saleable material to be rolled in scrap rolling mills.

ADVANTAGE The Start Stop Flying Shear can cut upto 18m/s with the standard DC motors. The solution lies in installing High Speed Continuous Rotating Shear with regenerative Tail Breaking Pinch rolls. The speeds of 22m/s with pneumatic deviator & 30 m/s with servo motor deviator have been achieved. The first cut of this shear is not accurate, but the subsequent cuts are very accurate. The material loss of first cut is compensated by the subsequent cuts. The motor power is only 50 KW, compared to 90, 130, 175 KW of Start Stop Flying Shear. RANGE 8mm to 16mm TMT bar. Single Shear is sufficient for ingot rolling mills. APPLICATION To cut set lenth of TMT bar being rolled above 20m/s at a temperature of 550 deg C FEATURES The casing is vertically split to take the separating force during the the milli seconds when the cut is executed on the casing profiles instead of parting bolts. The blade holder is fitted with double cone torque couplings as a safeguard against the accidental overload. The Flywheels are provided to reduce the motor power. The flywheel intertia augments the cyclic cutting load. The gears are case carburised hardened & ground designed for minimum back lash.

Our company designs supreme quality Chain Transfer Systems, which are installed at the side of run out roller table after the cold shear. In this, the first chain set cuts across the run out roller table after the cold shear. It has its resting on the common tie bar, which is fixed with the pneumatic cylinders. The cut bar lot in the system received on the run-out roller table, where the chains set lifts. Here, the chain moves across the rolling line & shifts the cut bar lot to the set distance of the chain transfers. Further, the middle chain runs at superior speed to spread bar for removing the random length and the third chain for manual bundling. Therefore, in last the bundle is thrown in the cradle or on to some other roller table where transferring it to U- bending station is done.
