When a sufficient quantity of molten iron accumulates in the hearth of the blast furnace, it is tapped off into ladles for steelmaking. As slag builds up on the surface of the molten metal it, too, is tapped off at regular intervals through a separate 'notch' or taphole. Meanwhile, the raw materials continue to be charged into the top of the furnace, and heated air blasted in at the ...
The blast furnace process has been the primary method for producing iron for many decades. The blast furnace is a refractorylined circular shaft 100 to 200 feet high, with an internal diameter between 20 and 45 feet. The refractory wall lining typically measures two feet or more in thickness and contains more than 2,500 tons of refractories. Blast furnaces produce iron by exposing iron ore ...
Ferrous industry slag is waste product of all steelmaking manufactures. These materials should be reused or stocked. There is abundant literature on the subject of reuse and recycling of blast furnace(BF), basic oxygen furnace(BOF), electric arc furnace(EAF). However, due to the fact that ladle furnaces(LF) have only been constructed in significant numbers since the 1980's, the relatively low ...
Answer (1 of 7): First of all Holy F***! You are sitting on a pile whose potential worth in India is at least Rs. 300 crore (50 million)!! I am not sure what you are seeking here on Quora, when the answer should be obvious to someone in possession of such a humongous quantity of material, u...
Blast Furnace Slag What It Is, and How It May Be Used as a Building Material By Richard Gruen* B ... slag is dumped out of the ladles at a suitable part of the plant and allowed to cool in a pile. Then it is either processed in some way or else used or sold as such to fill in ground. A distinction is made between two kinds of slag, acid slag which can be drawn out into a string just like honey ...

Blast Furnace Slag (BFS) cement is the combination of Ordinary Portland Cement (OPC) and fine Granulated Blast Furnace Slag (GBFS) gained as a byproduct in the steel making manufacturer with below 70% to that of cement. Ground Granulated Blast Furnace Slag (GGBFS) is a fine glassy granule which encompasses cementitious possessions.
The liquid slag flows into "slag pots" (25) or into slag pits (not shown) and the liquid iron flows into refractory lined "ladles" (26) known as torpedo cars or sub cars due to their shape. When the liquids in the furnace are drained down to taphole level, some of the blast from the tuyeres causes the taphole to spit. This signals the end of the cast, so the "mudgun" (29) is swung into the ...
Ladle furnace slag samples were prepared for EDS analysis as follows: 4 grams of each powdered sample (particle size less than mm in diameter) was pressed into pellets of 20 mm in diameter (15 tons pressure, 30 s dwelling time). No binder material was applied. The samples were placed in standard sample holders and loaded into the spectrometer. Samples were irradiated by Xrays generated ...
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. This molten iron product can be cast into iron products, but is most often used as a feedstock ...
Slag runoff from one of the open hearth furnaces of a steel mills, Republic Steel Corp., Youngstown, Ohio. Slag is drawn off the furnace just before the molten steel is poured into ladles for ingotting Contributor Names Palmer, Alfred T., photographer
The slag must take up a large amount of S from the liquid steel (have a "high sulfur capacity") so that a significant amount of sulfur will move from the liquid steel to the slag phase. The example explores these two conditions for an equilibrium between liquid steel and .
Steel Ladle. Already the most versatile vessel in a steel shop, the steel ladle has become increasingly important due to secondary refining process requirements. A steel ladle is also the piece of equipment that consumes the largest amount of refractories in a steel shop, making design optimization essential for cost reduction, energy ...
Use of Blast Furnace Slag Aggregate in Concrete Hiraskar and Chetan Patil AbstractThe Iron industries produce a huge quantity of blast furnace slag as by–product, which is a non–biodegradable waste material from that only a small percentage of it is used by cement industries to manufacture cement. In the present investigation Blast Furnace Slag from local industries has been utilised ...
