There are various route to increase the strength of steel used tor construction. One ot the oldest route is the CTD Bar route. Here the bars are cold twisted after rolling. Another method is the Micro Alloying of steel to get high strength.
The problem with both these systems is the high labour, cost and time. In CTD bars the cost of twisting and this is the main bottleneck in all the mills. For Micro alloying the cost
alloying elements is very high.
To counter these problems, SMT has developed High Strength with High Ductility
TMT Quenched & Tempered Ribbed Bars of Grade Fe 415 & Fe 500 confirming to IS 1786
We are happy to offer our International Computerized Version with the latest development” Extended Nozzles’.
⇒ Cantilever Pinch Roll
PINCH ROLLS comprise of non-reducing rolls that are used to redirect the travel of a Hot Rolling Mill Product and to provide tension for a downstream process. The pinch rolls perform their function without negatively effecting mill productivity or product quality. It is installed at various places in a rolling mill such as between the roughing mill and the intermediate mill, before and after the TMT Quenching Box to maintain the speed and tension of bars. It is driven through an AC / DC motor and consists of 2 Hi Gear Boxes, Solid Rolls with Carbon Shaft.
A Cantilever Type Pinch Roll has a set of rolls projected from a main body using a bridge type construction and the rolls are fixed at only one end of the machine.
⇒ Tail Breaker Box
It is installed after the flying shear and before the cooling bed to reduce the velocity of the TMT Bars. It runs through DC or AC variable Drives. The Rolls are Separated Through Pneumatic cylinder.
It consists of steel fabricated body, Pneumatic cylinder, top and bottom rocker arms and rollers.
