PPRM is an industry leader in manufacturing high-productivity rolling mills with a running speed of 30 metres per second and above. When Shyam Steel Group, a leading TMT bar manufacturer in India, aimed to enhance its operations, they turned to us for strategic collaboration.
Shyam Steel Group required a state-of-the-art steel rolling mill capable of producing 330,000 metric tonnes of TMT rebars annually. The mill needed to achieve a top finishing speed of 32 metres per second for Ø10 mm rebars, catering to various steel grades and producing diameters ranging from 8 mm to 32 mm.
PPRM offered housingless stands with vertical/horizontal designs for reduced stress paths and a longer mill-bearing life. The design facilitated quicker roll-changing and gap-setting processes. The rigid structure of the design minimised roll jumping for better stock size control. The stands featured unique adjustable rest bars and air oil lubrication provisions that enhanced reliability and performance.
PPRM’s pinch roll was designed for high-speed operation for rebar diameters ranging from 8 mm to 32 mm. A direct DC motor drive was used to drive the continuous shear, and shifting of the bar was controlled through the servo motor to ensure precise cut lengths. The tail brake was engineered for high mill speeds up to 40 mps, particularly for 8-mm-diameter bars.
PPRM’s high-speed rotating drum was engineered to receive the bar at a maximum speed of 40mps. Receiving the bar at such high speed is the key to the success of high-speed rolling because of the high accuracy and control of the rotating drum. The automatic cooling bed featured a rake mechanism for precise bar alignment and cooling of the bar at atmospheric temperature, which is called self-tempering of the rebars. A perfect design is very important for the quality of the rebars.
When Shyam Steels was considering a partner for their rolling mill needs, PPRM stood out for several compelling reasons.
