Solid waste management is a critical issue worldwide. Effectively utilizing these solid waste resources presents a viable solution. This study focuses on Iron ore tailings (IOTs), a solid waste generated during iron ore processing, which can be used as supplementary cementitious materials (SCMs) but have low reactivity, hindering their large-scale …

1. Introduction. Slag examined in this study is defined as the predominantly silicate and oxide by-product derived from smelting metallic ore. The two main types of slag included in this discussion are from the primary production of ferrous ores, from iron and steel manufacturing, and from non-ferrous ores, from the recovery of base metals and …

In addition to hardening iron by adding small amounts of carbon and also some other metals to the molten iron, iron castings or forgings can be heat-treated to take advantage of the various physical properties of the different solid phases of iron. Pure iron reacts readily with oxygen and moisture in the environment and corrodes destructively.

Abstract—The formation of slag binders, which ensure the strength properties of iron ore pellets during reduction, is studied. The formation of dicalcium ferrite, which is not reduced, has been found. The formation of an irreducible binder, namely, dicalcium silicate (belite) is also discovered. However, this compound is characterized …

The addition of iron-ore pellets allows for the formation of free-running slag at the beginning of the heat blowing by increasing the content of iron oxides in the slag. Thus, no faults with the slag practice and leakage of the slag–metal emulsion have been found in the heats with the minimum consumption of scrap metal. At a consumption rate ...

In modern ferrous metallurgy, there are two main routes for steel production: the primary route converts iron ore via blast furnaces (BF) into pig iron, and pig iron via the BOF process into steel.The secondary route converts scrap via the electric arc furnace (EAF) into steel. The BF-BOF route contributes to 60% and the EAF route to 40% of the …

The first iron used by mankind, far back in prehistory, came from meteors. The smelting of iron in bloomeries probably began in Anatolia or the Caucasus in the second millennium BC or the latter part of the preceding one. Cast iron was first produced in China about 550 BC, but not in Europe until the medieval period. During the medieval period, means were …

Just below the middle of the furnace, the temperature is high enough to melt both the iron and the slag. They collect in layers at the bottom of the furnace; the less dense slag floats on the iron and protects it from oxidation. Several times a day, the slag and molten iron are withdrawn from the furnace.
