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%)

a Shaper is a Type of Machine Tool that Uses Linear Relative Motion Between the Workpiece and a Single-point Cutting Tool to Machine a Linear Toolpath. Its Cut is Analogous to that of a Lathe, Except that It is (archetypally) Linear Instead of Helical. (adding Axes of Motion Can Yield Helical Toolpaths, as also Done in Helical Planing.) a Shaper is Analogous to a Planer, But Smaller, and with the Cutter Riding a Ram that Moves Above a Stationary Workpiece, Rather Than the Entire Workpiece Moving Beneath the Cutter. the Ram is Moved Back and Forth Typically By a Crank Inside the Column; Hydraulically Actuated Shapers also Existrke Roller Guides Can Be Used for the Guiding of Many Sections such as Leader and Breakdown Ovals, Squares, Hexagons, and Octagons. the Roller Guide Can Be Used for Hand Rolling, Continuous and Repeater Rolling, and Enable the Last Method Be Used Even for Small Leader Ovals Down to 5mm Round. the Rolling of Large Rounds is Made Much Easier By the Use of Roller Guides.
the Roller Guides are Delivered to Suit Ant Type of Rest Bar.
rollers are Fitted with Strongest Ball/ Roller Bearings. the Rollers are from Special High- Carbon, High- Chrome Steel.
fixing and Replacement of the Entry Made from Alloy Cast Iron Can Be Performed to Their Function Quickly.

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 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
