slag in the hearth since the furnace was cast dry. By 1957, Bosley et al. from the Steel Corp, together with Norwood B. Melcher from the Bureau of Mines, decided to come together and conduct a study on the quenching of the Bureau's experimental blast furnace at Pittsburgh [2]. The Bureau had earlier decided to dismantle the furnace
Blast Furnace Slag Material Description ORIGIN In the production of iron, iron ore, iron scrap, and fluxes (limestone and/or dolomite) are charged into a blast furnace along with coke for fuel. The coke is combusted to produce carbon monoxide, which reduces the iron ore to a molten iron product.
The objective behind this annual exercise is to have a builtin compliance mechanism for environment and forest safeguards and encourage all mining lease holders to strive for excellence. Initially, Indian Bureau of Mines (IBM) felicitated 19 mines with 4 and 5 star ratings.
The slag produced at blast furnace during pig iron manufacturing is called blast furnace slag. The slag produced at steel melting shop is known as steel slag. Slag output obtained during pig iron and steel production is variable and depends mainly on composition of raw materials and type of furnace. Typically, for ore Steel Plant Capacity for granulation
