Chain Scraper Reclaimers
A chain scraper reclaimer moves ore and other materials stored in stockpiles to a conveyor that transports the material to the next stage of the production process.
Continuous Unloaders An unloader uses a bucket to unload coal, iron ore, and other loose material from a freighter. A continuous unloader can unload more efficiently and in less time, equating to much lower landing costs.
Bucket Wheel Reclaimers Bucket wheel reclaimers feature buckets attached to a wheel at the end of a boom. The wheel rotates and feeds material from the stockpile to the next process

Unloader Chains and Sprockets
Unique technology gives Tsubaki Unloader Chain its superb endurance and proven track record. We also offer various specifications and series to match the needs of the conveyed items. Unloader sprockets are optimized for use with unloader chains. We specially harden them for extremely effective wear resistance.
Special hardening
Backstop Cam Clutches ackstop Cam Clutches
Tsubaki’s Backstop Cam Clutch products use a non-rollover design. The load distribution is among multiple cams and a large surface cross section, so even if an unexpectedly large reverse torque occurs, the clutches will not roll over. This will prevent the conveyor from reversing.
Steel Cable Carrier Systems
Steel Cableveyor ® has excellent strength and heat resistance. Stainless steel and side mount specifications are also available. We also offer an extensive line-up of tube type Cableveyors for added cable/hose protection.

Sintered Iron
Sintering P lant
In the sintering process, powdered iron ore, which makes up the majority of imported iron ore, is fused to create sintered ore.
Blast Furnace
Coking P lant Coal in the furnace is distilled to manufacture coke. Iron is extracted by reducing iron ore in the presence of carbon, which also becomes a source of heat for melting ore and limestone.
Here, iron is created from iron ore. Iron ore and coke are alternately charged in the furnace from the top, while hot air is pumped in from below. The CO2 generated from the burning coke reduces the iron ore to iron. Temperatures inside the furnace can reach 2000°C. The melted iron (hot metal) is removed from beneath the furnace.

Drive Sprockets
Comparison of Hardened Layers
We ensure that our Tsubaki roller chain sprockets have a deep hardened layer over the entire sprocket – even the tooth bottoms. This ensures superb wear life for tooth bottoms and long life for the sprocket. We offer an extensive line-up of sprockets with a wide-ranging number of teeth, rows, and shapes, as well as finished bore sprockets and bore fasteners.

Power Cylinders
Tsubaki Power Cylinders are electric cylinders that can operate with just simple wiring. With no troublesome hydraulic or pneumatic pipes to worry about, maintenance is a snap. Standardized operation for small to large thrust forces, diverse options, and various built-in overload safety devices give our users peace of mind. Highly efficient ball screws provide long service life even under high speed/high frequency use.
Hybrid Cable Carrier System
Hybrid cable carrier systems (sideband made of plastic and stays made of aluminum) are available in 1mm width increments to perfectly fit to the available mounting space. When operating on crane systems, the carriers run safely in guide channels made of steel sheet metal which are custom-made for any application. In doing so, we can accommodate almost any request for special shapes and fastening options.

Dummy Bar Car
Converter
Continuous Casting
Here, the hot metal from the blast furnace is reduced to form molten steel. The hot metal contains carbon, silicon, phosphorus, and many other impurities, so it is transferred to the converter, where oxygen is blown in from above and below to oxidize and remove the impurities. This allows the required optimal components to be adjusted to make steel.
Here, the molten steel reduced in the converter is hardened and shaped into billets. The molten steel taken from the converter is continuously poured from the ladle into a mold below and cooled. The cooled, hardened steel is cut to specific lengths and carried to the rolling process to be shaped.

T Series Power Cylinder
The T Series Power Cylinder is a heavy thrust type power cylinder that uses AC power. Tsubaki offers a wide range of models to match any application, thrust, or speed. Thrust ranges from 2.45 to 313kN{250 to 32000kgf}, with a maximum stroke of 2000mm. All models use a braked motor for reliable load support and safety. Heat resistant and other special braked motors can be easily installed for high temperature environments.
Dummy Bar Car Chain
This chain returns dummy bars used in continuous casting to their original position. The attachments are individually designed to match the customer’s dummy bars. The plates and the part of the attachment that engages the dummy bar are quench hardened for added strength.

TKV/TKI Series Steel Cableveyor ® S/SX1252B / 1802B
TKV Series Cableveyors have a maximum stroke of 30m (100m for the TKI Series). The maximum travel speed of the TKV Series is 150m/min, and TKI Series 120m/min, so they are usable in high frequency, high speed, and long travel stroke ranges where previous steel Cableveyors were not. The optimized geometry of S/SX 1252B and S/SX 1802B reliably prevent costly downtimes and maintenance breaks for the entire system – especially in environments, where large amounts of very fine, abrasive media are generated. Foreign bodies entering into the system are removed from the stroke system by the self-cleaning effect of the cable carrier in motion.

P ickling
The surface scale (iron oxide) formed on hot coils in the hot rolling process are washed off (“pickled”) using hydrochloric acid.
Cold Rolling
Here, hot coils are rolled to a usable thickness at room temperature. Coils rolled even thinner during this process are called cold rolled coils.
Hot Rolling
Here, slabs are pulled to make steel strips. The slabs are reheated to 1250°C and rolled while hot. The rolled strip steel is then wound up like a roll of toilet paper (called a “hot coil”).

NEP Series Roller Chain
Lines subjected to cold water sprays have problems with corrosion. With NEP Series, the pins, bushes, and plates have a unique triple layer coating, and the rollers are also specially coated, for added corrosion resistance. NEP Chain does not use hexavalent chromium, cadmium, mercury, or arsenic and so is RoHS compliant.
Covered Cable Carrier Systems
Covered or closed steel cable carrier systems should be used for applications where hot chips or severe contamination occur. The cover system also protects the layed cables against short-term radiant heat impact. Available as covered types with the robust Covered system RMD or economically priced, light covered types (steel band cover) for flying sparks and small chips.
