Todays mills can be used in a wide range of configurations in order to provide an ultimate selection of products from a single mill layout. It is possible to change from one unrelated product to another by simply pushing buttons and without the lengthy procedures needed for an old style mill change over. Convertible stands allow either horizontal or vertical positioning of the intermediate finishing trains in accordance with production requirements.

Features:

• Less than two minutes to change the position
• Excellent stand rigidity
• Reduced fountain depth
• Quick stand change system without crane requirement

High rigidity, reliability and quick roll change capabilities are the key features of the state of the art mill stands, which are designed for producing bars, wire rod, angles, channels, and universal beams. The connection and disconnection of the spindles and all the fluid utilities are fully automatic and therefore the stands can be interchanged very quickly. Different versions including horizontal, vertical, convertible and drop-in-joker (which converts a horizontal to a vertical) are in operation, allowing rapid adaptation to the variety of the rolled products needed to fulfill stringent market demands. Line flexibility allows rolling with low temperature, high alloy, wide forming passes, etc.

Features:

• High competent rigidity
• Reduced stress path
• Fully automatic operation
• Axial roll adjustment
• Automatic screw- down system
• Possibility for adjustment under load
• A roll balance system, which eliminates backlash
• Minimum wear and positive engagement due to
• self-balancing spindle support
• Long bearing Life
• Automatic utility connections
• Sliding Stands

  Modern 2-high sliding stands are reversible and fully automatic. They represent an innovation solution for roughing and intermediate mills and constitute the latest stage of 3-high stand evolution.

This is an excellent system as it carries the bar in a closed channel, minimizing the accident hazards. Specifically while carrying out high speed rolling the system is an absolute necessity.Its design features makes it possible to work in conjunction with braking pinch rolls, minimizing the length of run-in. The operations of twin channel are automated and are guided by the discharge of the rods from dividing shear. An innovative idea for cast iron center boxes has drastically brought down maintenance time.

PPRM designs flying and static type cold shears, with clutch and brake or direct drive, to produce the ultimate and product. Both open & closed types are available, Extremely precise cutting, Quick change device for blade replacement, Handles quenched rebar and high alloy steels.

The wire rod block has a group and not individual drive for all stands, the shaping in the different passes is done with a calculated tension between the stands in the block in other words the shaping is not tension free like in the intermediate mill. The tension between the stands depends first from constant parameters like the shape of the groove, working roll diameter in the groove, roll diameter relations between the stands, calculated cross section reduction but also from variable parameters like bar temperature, spread of material in the groove depending from type of material and temperature of the material. The different types of material can have different deformation resistance and consequently different roll forces. With higher roll forces the groove open according the mill modulus. All that means that geometrical tolerances like diameter and roundness of the finished rod is not better than the tolerances of the intermediate mill train rolled entry section into the block due to the non uniform tension in the bar created by difference spread in the groove caused by different cross sections of the entering bar, due to different bar temperature, material properties regarding spreading and elongation.

Quenching Process Solutions in a capacity upto 100 Tons per hour, Self Tempering Process that ensures high Weldability, TMT Bars of Fe 415, Fe 500 & Fe 550 Grades, TEMPCORE endorsed production process, Technical Partnership with Herbert Rothe of Germany, TMT approved by SAIL and MES.
