Blast furnace slag Euroslag

Blast furnace slag is formed during the production of hot metal by thermo-chemical reduction in a blast furnace. During this continuous process, iron ore or pellets as well as fluxes (lime[stone] and/or dolomite) are heated under reducing conditions in the presence of heated air. Coke and other reducing agents (e.g. injected coal) are combusted to produce []

Ferrous Slag general information Euroslag

Jan 31, 2021· Blast furnace slag is made during the melting and reduction of iron ore in a blast furnace. Steel making slag (also: steel slag) is produced during the conversion of hot metal to crude steel in a basic oxygen furnace or during the melting of scrap in an electric arc furnace. If the crude steel undergoes further secondary steelmaking processes

Basic oxygen furnace slag Euroslag

Basic oxygen furnace slag. Basic oxygen furnace slag BOS (also called LD-converter slag)is formed during the conversion of hot metal from the blast furnace into steel in a basic oxygen furnace.In this process the hot metal is treated by blowing oxygen to remove carbon and other elements that have a high affinity to oxygen.

Euroslag Euroslag

Ferrous slag is the by-product of iron and steel manufacturing. It arises from the conversion of ores to iron, hot iron to steel, from melting scrap in an electric arc furnace or from the subsequent treatment of crude steel. Each year, about 45 million tonnes of ferrous slag (iron and steel slag) is generated in Europe.

Cement / Concrete Euroslag

Today, the main by-product of hot metal production in blast furnaces is granulated blast furnace slag (GBS, see statistics). After grinding to cement fineness (GGBS = ground granulated blast furnace slag) it is used as a main constituent of cement or as a separate concrete addition. Since the discovery of the latent hydraulic properties of glassy []

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 glassy 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

Ground Granulated Blast Furnace Slag an overview

Slag. Ground granulated blast-furnace slag, more commonly referred to as slag or slag cement, is a by-product of steel production. Slag is primarily composed of CaO, SiO 2, aluminum oxide (Al 2 O 3), and magnesium oxide (MgO). When used as part of a portland cement concrete, slag reacts with both the water (latent hydraulic reaction) and the

Slag recycling recovery

The terms blast furnace slag (BFS) and granulated blast furnace slag, as well as LD slag and electric furnace slag are used for finer distinctions. With high-quality iron ore grades with an iron content of 64 to 67 %, a blast furnace typically produces about 0.25 to 0.30 t of slag per t of pig iron.

GGBS Ground Granulated Blast Furnace Slag for Concrete!

Ground granulated blast furnace slag (GGBS) is a non-metallic product obtained as a byproduct from the blast furnaces used to make iron. Ground granulated blast furnace slag consists of silicates and aluminates of calcium and other bases. The size of its particles is less than 45 microns and specific surface area is about 400 to 600 m 2 /kg.

Cupola Furnace Slag: Its Origin, Properties and

A cupola furnace is the most frequently used furnace aggregate for cast iron production. A by-product of the production of cast iron in cupola furnaces is cupola slag. Its amount is 40–80 kg per 1 tonne of the produced cast iron, and that is one of the reasons why this material is not as favoured as, for example, the blast-furnace slag. The purpose of this article is to provide the basic
