Fiber Bearings are moulded from Plastic Laminate of Cotton fabric, bonded with phenol Formaldehyde Resin. It has wide Industrial Applications. |
i) The very low coefficient of friction, when wet, it enables reduction in POWER consumption. |
ii) Being highly resistant to abrasion, it also considerably reduces roll journal wear |
iii) Its large loading capacity brings about higher efficiency of the machine. |
iv) Water, the cheapest lubricant, can be used on the Bearings thus dispensing with the costly use of lubricating oils and / or greases. |
v) The specific gravity of Phenolic Plastic is 1.36, which is approximately 1/5th of any nonferrous metal. |
vi) Machines using Fiber Bearings have longer services, performance and high production efficiency. |

In a Rod Mill, the pinch roll is used for moving the material further when bar has left the mill stand. |
The main housing of Pinch roll is made from Cast iron, and fitted with EN - 9 rolls with spherical roller bearing housed in steel chocks. The tap roll setting device consists of screw down screw of EN - 8 with gun metal nut. The top roll is also spring loaded with helical spring for balancing. |
Gear box: The main body is fabricated from M.S.plate. The gears of EN-9 steel fitted on two shaft of EN-8 steel run on antifriction bearings. The gears and the bearings run in oil bath and provide adequate lubrication at all times. |
Spindle: The pinch roll and the gear box are coupled with two nos. Universal type spindle. |
Motor: The motor is coupled to one of the shaft by vee-belts. |
Base: The whole equipment is mounted on one common base plate fabricated from steel. |
STRUCTUREThe bridge will consist of two main girders of plate/box type welded and bolted construction. Suitable rail will be provided. A chequered plate will be provided full length of one side of the bridge. The platforms will have hand railling of approximately a meter high with a top rail, intermediate rail and toe guard. Substantial steel and stop will be provided at each end of the crane bridge securely attached the main girder.
END CARRIAGES The end carriage will be bolted and welded type of fabricated steel construction using rolled section and or plates. Rubber buffer will be provided at the four corners.
CRABThe crab frame will be of fabricated steel construction, welded and bolted with hoisting and cross travel motor, brakes, Gearbox, drums, electricals etc. Mounted on it. The rope drum will be machine cut Grooves and mounted on antifriction bearings. Rubber buffers will be provided at the four corners.
WELDINGWelding will be in accordances with IS:816-1956 and would eminently suitable for the duty required. Welding would be by hand electric arc. Our design would ensure avoidance of welding at critical points and all welds would be under low stress. WHEELSThe wheels for end carriage and crab Wheels will be of carbon steel En 9 hardened and tempered double flanged running on antifriction bearings. GEARINGThe gears and pinion shall be made of carbon/alloy steel. They are mounted on steel shafts, running on ball bearings. The gear box will be of cast iron/fabricated steel construction with oil bath lubrication. Input pinion shall be EN 24, hardened & tempered and other gears and pinions shall be of EN9. BRAKESUnless otherwise described specially E.H.T or Electro magnet brakes of the solenoid release type will be provided for the controlling of different motors. When the current will bring the motions safety and the brake will bring the motions safety and autometically to a rest. RESISTANCE BOXES Punched grid stainless steel resistance boxes shall be of 10 minutes rating as per IS:3177. HOOK BLOCK MAIN HOIST & AUXILIARY HOISTHook for the main hoist shall be of c-type of shape and section as indicated in relevant BS/IS Standered. The hook shall be steel forget. The hook shall be of swivelling type with thrust bearings. The block shall be of fabricated construction. Rope pulley will be of fabricated steel works of carbon steel, with rope grooves accurately machined. The pulley will be providded with the plain bearings and have suitable rope guards.
PULLEY FITTED ON CRAB In case of the number of falls of rope being more than two, pulley shall be fitted on crab frame also. The pulley will be fabricated steel work of carbon steel. It will have rope grooves accrately machined.

The rotary shear is used for cutting off the rod for two purposes: |
For removal of front and back ends |
For cutting the long length of a bar into smaller commercial lengths. |
The rotary cutters of EN - 24 steel, are mounted on a swivelling housing along with the motor and transmission gears. The speed of the cutters is synchronized with mill speed so that a neat cut is obtained |
Rods usually rounds from 5.5 to 9 mm and TMT Bars from 8 to 40 mm in diameter are produced in bar and rod Mill.
Three types of mills are employed in rolling rods: Open Train, Semi-Continuous and Continuous. The selection of the layout in any case depends upon the tonnage required, the volume of production and the required quality of the finished product and their rolling speeds which reaches 30m/sec. and even higher. The continuous rod mill consists of Roughing mill train, first intermediate mill train, second intermediate mill train and finishing mill train with D.C. drive.
Section cum Structure mills with Rolls 250 to 750 mm diameter are employed for the production of rounds and squares from 8 to 150mm in size, Beams and Channels from 50 to 300 mm in depth, Angles from 20 x 20 to 200 x 200 mm in size and other section. In accordance with the size of section they accommodate, these mills are often further classified as heavy-section mills with Rolls from 500 to 750 mm diameter, medium-section mills with 350 to 500 mm diameter rolls, and light-section mills in which the rolls are from 250 to 350 mm in diameter.
The installation of an in-line quenching process can produce steel reinforcing bars with high and very stable yield strength around 500N/mm Sq.
This TMT (Thermo-mechanical treatment) process exposes the bar to an intense cooling after the last rolling pass, providing excellent strength combined with good toughness, hardening of the surface layer and subsequent tempering by residual heat flowing from the core. The fast cooling of the core leads to a very fine ferritic pearlitic structure. Hence the mechanical properties required by several technical standards like ABNT, BSI, AFNOR, JIS, DIN, etc. regarding high strength bars may safely reach, even for analysis levels which normally apply to low resistance material only, as follows:
C :0.20 to 0.30%Si :0.10 to 0.30%Mn :0.60 to 0.90%Ceq :0.30 to 0.50%
Thus High strength material may be produced combined with weld ability characteristics.(C= 0.24, Ceq = 48%)
