actual ferrous slag production, but domestic slag sales1 in 2021 were estimated to be 17 million tons valued at about 460 million. Blast furnace slag was about 49% of the tonnage sold and accounted for 87% of the total value of slag, most of which was granulated. Steel slag produced from basic oxygen and electric arc furnaces accounted for

Iron and steel slags are coproducts of iron and steel manufacturing. In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent. The iron ore is a mixture of iron oxides, silica, and alumina. From this and the added fluxing agents molten slag and ...

Abstract. Ground granulated blast furnace slag (GGBS) is a byproduct from the blastfurnaces used to make iron. Blastfurnaces are fed with controlled mixture of ironore, coke and limestone, and operated at a temperature of about 1,500°C. When ironore, coke and limestone melt in the blast furnace, two products are produced—molten iron ...

What is Slag? There are two distinct types of slag produced at the BlueScope Steel Port Kembla Site; Blast Furnace Slag and Steel Furnace (or BOS) Slag. BLAST FURNACE SLAG. Iron is extracted from iron ore in a blast furnace by a process known as reduction. The raw materials iron ore, coke and fluxes are fed into the top of the furnace.

These different types are referred to as furnace or tap slag, raker slag, synthetic or ladle slags, and pit or cleanout slag. Figure 181 presents a diagram of the general flow and production of different slags in a modern steel plant. The steel slag produced during the primary stage of steel production is referred to as furnace slag or tap slag.

In 2016, Mta of blast furnace slag was produced, of which only Mta ( %) was granulated slag and Mta ( %) was aircooled blast furnace slag. In addition, Mta of steelworks slag was produced. Fig. 9 shows the amounts recovered. It can be seen that only granulated blast furnace slag (GBFS) can be used as a cement additive.
