A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally iron. In a blast furnace, fuel, ore, and flux (limestone) are continuously supplied through the top of the furnace, while air (sometimes with oxygen enrichment) is blown into the lower section of the furnace, so that the chemical reactions take place throughout the furnace as the material moves downward. The end products are usually molten metal and slag phases tapped from the bottom, and flue gases exiting from the top of the furnace.
Steel Authority of India’s (SAIL) Durgapur plant plans to engage a contractor who can supply three sets of skip car for blast furnace. Also, the company’s Bokaro Steel City, Jharkhand is looking out for a contractor for handling of Mudgun Mass at Bokaro.
Meanwhile, Rashtriya Ispat Nigam (RINL), Visakhapatnam, plans to hire a contractor for equipment repair jobs in blast furnace.
