Mechanical Power Transmission products for Upstream and Downstream in Steel Plant

Flexible Gear Couplings

High performance and easy in installation manufactured using fully automatic hobbing machine.

Roller Chain Couplings

Roller Chain Flexible Couplings are compact, long lasting flexible couplings, capable of transmitting relatively high torques with minimum of space consumption

Torque Limiter

Nu-Teck torque limiter is a protective device that limits torque transmitted in a drive system by slipping when torque demand exceeds a preset value as a result of shock loads, over loads, or machine jams.

Sprockets

Nu-Teck Sprocket Wheels are manufactured from quality materials. Teeth are hob-cut for correct tooth form, tooth thickness and profile.

Mechanical Power Transmission Products for Steel Plant

Upstream & Specialty Sections — Steel Plant

Beyond the rolling and coating sections, our products are critical in the upstream (raw material to liquid steel) and downstream (specialty finishing) stages of a steel plant. These areas are characterized by massive scale, abrasive dust, and the handling of molten metal.

Here are 20 additional applications across these unseen sections of the plant, where our Nu-Teck Couplings' power transmission products — Gear, Grid, Tyre, Pin & Bush, and Brake Disc Couplings, along with Heavy-Duty Sprockets — are essential.

Power Transmission Products for Upstream & Specialty Sections

20 Applications in Upstream & Specialty Sections

Application-wise coupling reference for all critical drive points across RMHS, Sinter & Pellet Plants, Blast Furnace, Continuous Casting, and Bar/Rod/Pipe Mills, grouped by process section

Application	Nu-Teck Couplings	Description

Raw Material Handling (RMHS) & Coke Ovens — Abrasive materials, high dust, heavy-duty transport
Wagon Tippler Drives	Gear Pinions & Gear Shafts	Rotate entire railway wagons 180° to unload coal and iron ore — high-torque, heavy-duty application.
Stacker-Reclaimer Slew Drives	Gear Pinions & Gear Shafts	Manage the massive inertia when the boom rotates to stack or reclaim raw material.
Main Belt Conveyor Drives	Tyre Couplings	Protect motors by absorbing the shock of starting 2 km-long loaded conveyor belts.
Apron Feeder Drives	Sprockets	Move the slow-speed, high-torque pans that feed raw ore into crushers.
Coke Pusher Machine	Gear Couplings (Specialized)	Drive the ram that pushes 1,000°C coke out of the oven into the quenching car.
Sinter & Pellet Plants — Extreme heat and continuous abrasive grit
Sinter Machine Drive	Sprockets (Large)	Drive the pallets (moving grate) that bake iron ore fines into sinter.
Circular Cooler Fans	Grid Couplings	Handle the high-speed vibration of fans cooling hot sinter after the sintering process.
Primary Jaw Crushers	Tyre Couplings	Essential to absorb the violent shocks of crushing large ore lumps in primary crushing.
Pelletizing Disc Drives	Pin & Bush Couplings	Synchronize the rotation of the massive discs that form green pellets from iron ore fines.
Blast Furnace (BF) & Steel Melt Shop (SMS) — Critical safety and molten metal handling
Skip Hoist Drives	Nu-Teck Brake Disc Gear Couplings	Ensure the bucket carrying raw materials up the furnace shaft stops instantly and safely.
Ladle Turret Rotation	Gear Couplings (Massive)	Rotate the turret holding 300 tons of molten steel at the Continuous Caster.
Slag Granulation Pumps	Chain Couplings	Drive the pumps that blast water into molten slag to turn it into sand-like granules.
EOT Crane Hoists	Brake Drum Gear Couplings	Mandatory on cranes lifting ladles of liquid steel — provide fail-safe holding torque.
Continuous Casting Machine (CCM) — Precision speed for solidification
Mould Oscillation Mechanism	Precision Gear Couplings	Drive the rapid shaking of the copper mould to prevent the steel strand from sticking.
Withdrawal & Straightening Rolls	Gear Spindles	Pull the partially solidified strand through the machine at a perfectly constant speed.
Torch Cutting Machines	Chain Sprockets (Small)	Move the gas torches that cut the continuous slab into specific lengths.
Bar, Rod & Pipe Mills — High speed and complex material handling
Wire Rod Finishing Block	Grid Couplings (High-Speed)	Manage the vibration of rods traveling at 100+ meters per second through the finishing block.
Pipe Threading Machines	Tyre Couplings	Allow for the slight misalignment needed when gripping and rotating large steel pipes.
Cooling Bed Rakes	Chain Sprockets	Facilitate the lateral stepping movement of bars as they cool on the cooling bed.
Straightening Machines	Gear Couplings	Provide the high torque required to remove bends from finished steel sections.

Customised Gear Couplings for These Sections

Because these areas involve unique hazards — molten metal, heavy dust — Nu-Teck offers these specific customizations engineered for the demands of upstream and specialty steel plant sections

Coupling / Product Type	Description & Purpose
Nu-Teck Labyrinth-Sealed Gear Couplings	For RMHS and Sinter Plants — use a tortuous path seal rather than a standard O-ring to prevent abrasive iron ore dust from entering the gear mesh.
Nu-Teck Vertical Mounted Gear Couplings	Specifically designed with internal thrust buttons for Agitators and Vertical Pumps used in water treatment and chemical sections.
Nu-Teck Insulated Gear Couplings	Used in Induction Furnaces to prevent electrical currents from jumping from the motor to the driven equipment.
Nu-Teck Torque-Limiting (Safety) Couplings	For Crushers and Conveyors — feature a break-away mechanism that instantly disconnects the drive if the machine jams, preventing motor burnout.
Nu-Teck High-Speed Dynamically Balanced Couplings	Customized for Oxygen Plant Compressors and Turbo Blowers to prevent whine and bearing failure at speeds exceeding 3,000 RPM.
