Blast Furnace Slag - an overview ScienceDirect Topics

Blast furnace slag (BFS) is a by-product from iron production in blast furnaces, which are fed by a mixture of iron-ore, coke and limestone. In the process, the iron ore is reduced to iron while all remaining materials form the slag, which is tapped off as a molten liquid and cooled.

Blast Furnace Slag - an overview ScienceDirect Topics

Blast furnace slag is a calcium-silicate-based product removed from the top of molten iron during its extraction from ore in a blast furnace. Usually, it is rapidly cooled to a Limestoney state and ground for use in construction materials (Provis et al., 2015). By the step of water quenching and out of rapid decrease in temperature, most of the compounds have not reached a stable phase. The slag ...

Blast Furnace B - Blogger

I selected this furnace as a basis for my model for two reasons - first, the wealth of HABS/HAER information (drawings, text, and photos) on this facility; and second, this furnace was used to produce ferromanganese. Ferromanganese production will add a lot to the operation of the railroad as there are different and and or more raw materials handled - more slag - different cars for handling ...

Effect of High Al2O3 Slag on the Blast Furnace Operations

The slag fluidity in a blast furnace affects softening-melt-ing behavior in a cohensive zone, permeability in the lower part of a furnace due to liquid hold-up in a dripping zone, liquid flow in a furnace hearth, and the ability of the drainage slag by a taphole. The slag fluidity is affected by temperature and composi- tion, with the latter influenced by ore gangue minerals and ash ...

Slag produced by direct reduced iron in an electric arc furnace is not comparable to blast furnace slag because it has no latent hydraulic properties. Hence, we need to compare a production route which produces stones as by-product with a production route that produces a cement substitute. To compare carbon footprint of steel produced by both production routes, the blast furnace route should ...

The slag is directed to the slag ladle cars through troughs on the front side of the blast furnace. The molten slag is poured into a slag pit, where it solidifies and is scraped up and dumped into dump trucks, for processing into ballast, or other materials. The ladles are open topped, therefore, the slag pit cannot be located very far from the Blast Furnace. The molten iron passes down ...
