Tsubaki provides the best solutions for steelmaking equipment--Applications in the Stock Yard

Steelmaking
Stock Yard

Iron ore, coal, and limestone are unloaded from ships and stored in the stock yard. This material is then fed to the sintering plant, coking plant, and blast furnace in the pig iron plant.

Continuous Unloader --Unloader Chain & Unloader Sprockets/Steel Cableveyors/Helical Reducers

An unloader uses a bucket to unload coal, iron ore, and other loose material from a tanker. A continuous unloader can unload even more efficiently and in a shorter time, meaning much lower landing costs.

Chain Scraper Reclaimers and Bucket Wheel Reclaimers --Reclaimer Chain/Heavy Duty Roller Chain

A chain scraper reclaimer reclaims ore and other loose material stored in the stockpile. The shoveled material is then fed to the next process. Reclaimer types include chain scrapers and 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.

Reclaimer Chain

When abrasive material infiltrates between bushes and rollers, and infiltrates outboard rollers, the rollers lock and wear accelerates, causing your chain to reach its wear life. Using Tsubaki's dust resistant bearing rollers can extend the life of your reclaimer chain.

Raw Material Belt Conveyor --T Series Power Cylinder

The belt conveyors that connect the stockyard and other processes are used outdoors, and pooling rainwater can negatively affect the raw material. Power cylinders are used to push up on the center of the conveyor and drain any pooled water.

Features a wide range of functions to match any application, thrust, or speed needs. These are tough, high precision electric cylinders, so they can even be used outdoors. (IP55)

APP Series Roller Chain: Perfect for hash environments such as outdoor and coastal areas

Offers outstanding protection in corrosive environments.

APP Series Roller Chain

Uses a special surface coating on the pin that does not lower its strength for protection against pitting corrosion, which leads to fatigue breakage.

APP Series Roller Chain

APP Series features
  • Chains have the same tensile strength and allowable load as standard steel chains. There is no loss of strength.
  • Chromate free. The special pin surface treatment uses no harmful hexavalent chromium.
Available models
  • Single/double strand RS Roller Chain
  • Single strand Heavy Duty Chain

Contact a Tsubaki representative for more information.

The example of fatigue breakage from pitting corrosion

fig.

Pitting corrosion on a pin is a type of localized corrosion, where the corrosion is locally concentrated on the surface of the metal and then propagates inward, resembling a pit. Pitting corrosion that occurs on a pin's surface becomes the origin point that will quickly lead to fatigue breakage and chain failure.

APP Series roller chain prevents this kind of fatigue breakage.
