| 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. |

| Application: To cut finished TMT bars to specific length automatically through sensing device & PLC, drive through DC motor or AC variable drive. |
| Cutting capacity: 8mm to 32mm TMT bars |
| Structure: The body is steel fabricated and stress relieved and machined accurately to take the pinion which are hardened ground. Anti frictions spherical roller bearings are used of SKF/NTN make for better performance. |
| Body: Steel fabricated, stress relieved. |
| Gear/Pinion: EN-24 steel, double helical, ultrasonic tested. |
| Bearings: Antifriction spherical roller. |
| Stage: 1 stage |
| Shaft: EN-9, forged steel ultrasonic tested. |
| 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%)
