Refractories manufacturer Magneco/Metrel reports it has helped to start the world’s largest blast furnace with its installation of almost 2,500 of its Metpump refractories. The silica-bonded pumpable refractories line the new 5,500-m 3, working volume furnace, operated by Shougang Jing Tang United Iron and Steel Ltd. at Caofeidan, China. The furnace is rated to produce over 5 million metric tons/year of iron. Magneco/Metrel noted that a second identical facility is under construction at the site. http://foundrymag.com/materials/worlds-largest-bla… ————————— The largest blast furnaces have a volume around 5580 m3 (190,000 cu ft) and can produce around 80,000 tonnes (88,000 short tons) of iron per week.This is a great increase from the typical 18th-century furnaces, which averaged about 360 tonnes (400 short tons) per year. http://en.wikipedia.org/wiki/Blast_furnace#Modern_… ——————— Contact the american iron and steel institue. I hink the largest furnace in the US has 40 tuyeres and makes 12000 tons per dayhttp://answers.yahoo.com/question/index?qid=200706… ———— Posco has become the world’s first steel manufacturer capable of producing five million tonnes of steel per year from a single blast furnace for the first time since the operation of its first blast furnace 36 years ago. The company recently (July 21) re-opened its refurbished 5500-cubic-meter No. 4 Furnace at its Gwangyang Plant, complete with a blowing-in ceremony for rekindling the renovated furnace. The restated furnace is to produce some 14,000 tonnes of steel per day, earning it the distinction of being the world’s largest blast furnace in terms of daily production.http://steelnews.com/Coke,%20Iron%20and%20Alternat… ———— The Schwelgern blast furnace plant in Duisburg, Germany, is home to blast furnace Schwelgern 2, Europe’s largest blast furnace and one of the biggest of its kind in the world.The furnace has a 5 513 m3 capacity with a hearth diameter of 14.9 m. Hot air is injected into the large-scale furnace through its 42 tuyères, creating a high temperature ideal for smelting.The furnace produces around 12 000 t/d of hot metal and about 3 300 t/d of ground granulated blast furnace slag, which is used as a basis for cement manufacture.http://www.miningweekly.com/article/europes-bigges… ——————- The Indiana Harbor plant is the largest steelmaking facility in North America, covering more than 3,100 acres and operating five blast furnaces that transform iron ore, coke, limestone and scrap into molten iron – and ultimately, high-quality, finished steel.The process for converting these raw materials into steel is very energy intensive. The facility produces 9.5 million tons of steel annually http://energy.gov/articles/steel-manufacturer-prov…...
