Various Tsubaki products are Sinter plant Blast furnace

used in the steelmaking industry. Steelmaking involves various processes. You’ll find Tsubaki products everywhere, from unloading iron ore and coal from ships to shipping coils of products. Based on the expertise, quality, and technological capability cultivated since 1917, Tsubaki contributes to the world together with steelmakers and steelmaking equipment manufacturers around the globe.

Steelmaking Processes and Main The steel items found around us are made through various processes. First, raw materials such as iron ore, coal, and limestone, are received, then they are used to produce steel using blast furnaces and converters before the steel goes through continuous casting and rolling machines to become products. Tsubaki products support these important processes.

Material yard The material yard plays the roles of unloading and storing iron ore, coal, and limestone from ships, and then supplying these to the sintered ore and coke production processes in the pig iron plant. Steel cable carriers Steel cable carriers with superior strength, rigidity, and heat resistance. Stainless steel types, special surface treated types with excellent cost performance, and horizontal types are also available. Continuous unloaders Horizontal arrangement Unloader chains Tsubaki unloader chains are used by various customers that rely on their superb durability made possible...

Bucket wheel reclaimers Overload protectors The swivel ring gears of reclaimers are driven by pinions. Tsubaki’s mechanical protection equipment instantly prevents overloads for even large machines due to clogging of coal or fragments in gears. Power Cylinders Bucket wheel reclaimers A wheel with buckets is attached to the end of the boom for this type of reclaimer. The wheel is rotated to transport bulk materials, e.g. ores, piled in the storage yard to the next process. Tsubaki Power Cylinders are electric cylinders that can be put in service with just simple electric wiring. This means simple...

The pig iron making process extracts iron from iron ore. Here, sintered ore and coke are produced, and molten iron is taken out of the blast furnace. Coke plant The coke plant fires coal in a furnace to produce coke. Coke provides a heat source for extracting iron by reducing iron ore with carbon, and for melting iron ore and limestone. CDQ uses inert gas rather than water to cool coke, then recovers exhaust heat to generate electricity. Tsubaki’s Power Cylinders are employed in many CDQs, contributing to energy savings at steel mills around the world. Compared to hydraulic cylinders, Power Cylinders...

Sinter plant Coke plant Sinter plant The sintering process fires powdered iron ore (which comprises the majority of iron ore received) to produce sintered ore. Indicator pins (replacement alert mark) Inspection with indicator pins Scrap conveyors The service life limit is reached when teeth are worn to the point that they contact the mark. (Prepare for replacement if teeth come close to the mark.) Sprockets equipped with Tsubaki indicator pins (replacement alert mark) are recommended when sprockets are used in dusty or otherwise severe environments. They indicate the impending need for replacement...

Blast furnace Blast furnace Sintered ore The blast furnace produces iron from iron ore. Iron ore and coke are fed alternately from the furnace top, while a blast of hot air is blown from the furnace bottom. The CO2 gas generated by combustion of coke reduces iron ore to iron. As temperature in the furnace reaches as high as 2000°C, molten iron is removed from the bottom of the furnace. Belt conveyor for feeding raw materials Slag and molten iron Roller chain couplings Miter Gear Boxes Each roller chain coupling consists of a double strand roller chain wrapped onto two sprockets. The chain is...

Steel mill In the steel mill, the pig iron (molten iron) produced in the blast furnace is decarbonized in a converter furnace to form molten steel. The next process is continuous casting, where molten iron solidifies and gets cast into billets of a given shape. Converter Here, the molten iron from the blast furnace is refined into molten steel. As molten iron contains large quantities of impurities, e.g. carbon, silicon, and phosphorus, it is transferred into the converter, where blasts of oxygen are blown from both top and bottom to oxidize and remove impurities. This produces steel of the required...
