The Rolls For Re-Rolling Mills Are Manufactured By Forging And Centrifugal Spin Casting Process. The Rolls Manufactured In Alloy Steel Grades Such As EN-9, EN-42, And Unalloyed Grades Like Spheroidal Cast Iron And Chilled Castrolls.

These Bearing Chokes Are Of Rolling Mill Duty And Blend In Between Window Of Rolling Mills Stands. These Bearings Chokes Are Suitable For Anti Friction Roller Bearings. The Bearings Chokes Are Of EN-8 Machined Accurately With Bearing Sizes. The Bearings Chokes Are Complete With Side Cover, Sleeves/Lumbering And Chuck Nut.

A Charging Pusher Is An Electro-Mechanical Or Hydraulic Device Which Is Used For Feeding Charging Of Raw Material (Like Ingots, Billet Etc.) Into The Reheating Furnace. Various Components. Which Are Used In The Manufacture Of A ChargingPusher Are Heavy Steel Slab Frame, Pushing Screw With Pushing Slab, Multi Stage Type Reduction Gear Box Or A Hydraulic Power Pack With Alloy Steel Shafts In Case Of A Hydraulic Pusher. Depending On The Raw Material To Be Fed I.E. Scrap Roll, Ingots /Billets Or Heavy Blooms And Their Sizes The Mechanical Or Hydraulic Type Pusher Is Designed And Supplied.

Used In Pairs Between Roughing And Intermediate Finishing Stands To Crop Front And Back Ends In Strip TMT Bar/Wire Rod Mills.

The Basic Function Of Pinch Rolls Is To Push The Material In A Particular Direction. It Does Not Cause Any Kind Of Physical Change In The Material And Is Usually Used To Move The Material Over A Distance. 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 Garden Shaft.

A Fly Wheel Is A Heavy Metal Wheel Attached To A Drive Shaft, Having Most Of Its Weight Concentrated At The Circumference, The Main Function Of A Flywheel, Is To Reduce Speed Fluctuation By Strong Extra Energy During Part Load As Kinetic Energy And The Same Is Released During Overloading. By Slowly Increasing The Speed Of A Fly Wheel, Small Motor Can Store Up Energy Which Enables The Motor To Perform A Function For Which It Is Ordinarily Too Small.

Discharging Ejector Is An Electro-Mechanical Device Which Is Used To Expel The Hot Material From The Re-Heating Furnace To The Rolling Mill. It Has A Mill Housing Type Structure With A Movable Frame And Can Do Both Front And Side Travel For Discharging Of Hot Material(Like Ingots, Billets)From Re-Heating Furnace. It Comes Complete With Heavy Stand, Rollers, Cooling System, Wheel For Cross Travel, Gear Box, Pushing Arrangements Etc. It Uses A Square Billet Of Approx.6 Meters(Or More)Length As The Device To Push The Hot Material Out Of The Re-Heating Furnace. It Is Manufactured Depending On The Size And Capacity Of The Re-Heating Furnace.

A Gear Coupling Is Used For Transmitting Torque And Power Between Two Shafts. It Is Normally Used For The Coupling Of Motor To Fly-Wheel , Flywheel To Gear Box Etc. It Is A Individually Designed And Manufactured To Specific Requirements. It Is A Triple Crowned Double Engagement Type With Hexagonal And Alien Bolt, Forced Greased Having Reamed Flange Hole. We Provide Half And Full Gear Couplings Of 101 And Above Sizes As Per The Customer's Requirements.

The Gear Boxes (Reducers) And Pinion Stand Designing And Manufacturing Is Also The Frame Of Our Technical And Engineering Expertise With Modern Features As Per Industrial Standards And Requirements. The Gear Boxes Are Highly Efficient Due To Case-Hardened Steel Of High Strength Bearings Of Ample Dimensions, Steel Fabricated Body For Smooth Running And Low Noise.
