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

Application of Phase Change Materials in Heat Recovery from Blast Furnace Slag Renuka Sahu1 1Department of Mechanical Engineering, National Institute of Technology Raipur Raipur, Chhattisgarh, India Abstract The objective of this paper is to suggest a suitable method for heat recovery from blast furnace slag in a steel industry using a suitable Phase Change Material (PCM). The system will
A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.. In a blast furnace, fuel (), ores, and flux are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with
Blast furnace slag (BFS, see Wikipedia ground granulated blast-furnace slag) is a nonmetallic byproduct of the manufacture of pig iron in a blast furnace. BFS consists primarily of silicates, aluminosilicates, and calcium-alumina-silicates. BFS forms when slagging agents (e.g., iron ore, coke ash, and limestone) are added to the iron ore to
BLAST FURNACE SLAG User Guideline. Embankment or Fill. INTRODUCTION. Both air-cooled blast furnace slag (ACBFS) and expanded blast furnace slag can be used as a conventional aggregate in embankment or fill. They are generally considered by many specifying agencies to be conventional aggregates and require minimal processing to satisfy
√ Artificial coal furnace. Applications of Slag Dryer Machine. Thanks to its own cleaning device and material lifting plate, slag dryer is extensively applied to dewater wet materials with large specific gravity. Slag dryer is mainly used in smelting field like iron industry for the tailings of blast furnace slag drying;
2014-06-06· The blast furnace (BF) cast house is the working area where hot metal and liquid slag are tapped from the blast furnace and either poured into ladles (torpedo car or open top ladle) or led off for solidification (pig casting and slag granulation) or treatment (cast house desulphurization).
The Blast Furnace is a heat based machine using solely for the creation of Steel.To create Steel with the Blast Furnace, input a source of Iron, such as Iron Ingots, Iron Ore, or Iron Dust, and also 6 Compressed Air Cells.To start the process, the Blast Furnace needs an input of Heat through the orange square on the side of the block.

Mini Blast Furnace and Iron making. Mini blast furnaces (MBF) are generally viewed as miniature versions of the conventional large blast furnaces (BF). These furnaces are ideally suited for small scale operations. In fact, they are basically the forerunner to modern conventional last blast furnaces and hence they have operated for a longer
blast furnace slag. Grading Expanded blast furnace slag is crushed and screened to desired product sizing. Typically this is a blend of coarse and fine aggregate particles. The actual grading of products should be reviewed with the local supplier. The Process In the pelletizing process, a molten blast furnace slag stream is directed onto an

In the Furnace Hot Metal, (along with slag) is processed from the raw material which gets collected in the hearth and blast furnace gases come out of blast furnace from the top. ii) Cast House: In the Cast House Hot Metal,& slag are tapped from the Furnace tap hole and Hot metal and slag are separated in the refractory lined main iron trough
Basic oxygen steelmaking (BOS, BOP, BOF, or OSM), also known as Linz–Donawitz-steelmaking or the oxygen converter process is a method of primary steelmaking in which carbon-rich molten pig iron is made into steel. Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into low-carbon steel.
