Iron and steel slag, also known as ferrous slag, is produced by adding limestone (or dolomite), lime and silica sand to blast furnaces and steel furnaces to strip impurities from iron ore, scrap and other ferrous feed materials and to lower the heat requirements of the iron and steelmaking processes.
By using steel scrap to make new steel, the North American steel industry conserves energy, emissions, raw materials and natural resources. This need for a continuous feedstock of steel scrap directly drives the recycling of many common steel products, including cans, .
Steel slag can also be produced by smelting iron ore in a basic oxygen furnace. According to methods for cooling molten steel slag, steel slag is classified into five types: natural aircooling steel slag, waterspray steel slag, waterquenching steel slag, airquenching steel slag, and shallow box chilling steel slag .
The applications of steel slag powder and steel slag aggregate in ultrigh performance concrete (UHPC) were investigated by determining the fluidity, nonevaporable water content, and pore structure of paste and the compressive strength of concrete and by observing the morphologies of hardened paste and the concrete fracture surface. The results show that the fluidity of the paste containing ...
Industrial uses of slag—The use and reuse of iron and steelmaking slags R. DIPPENAAR Steel Institute, University of Wollongong, Northfields Avenue, NSW, Australia Traditionally, iron ore has been reduced with coke in a blast furnace and the hotmetal product of the blast furnace containing carbon, manganese, silicon, sulphur and phosphorous, was
Recycling Iron and Steel Slag. Every year, the Kakogawa Works and Kobe Works together generate about million metric tons of blast furnace slag and million metric tons of steelmaking slag as secondary products. Both types of slag are reused as a raw material for cement or as a bedding material in road construction. Compared with regular ...
The specific charge of metal stock when melting with slag removal as shown in Table 1 is more by kg/t of steel and related to higher slag oxidation (by %) and additional iron loss with ...
Abstract. The internal recycling process of BOF slag which is one of the huge solid wastes from iron and steel industry was emphasized. Based on the four scenarios of different internal recycling strategies for BOF slag, life cycle assessment (LCA) as a valuable tool for industrial solid waste management was applied to analyze the contribution to reducing environmental impacts and resources ...
Steel slag is a residue produced by refining iron to steel in openhearth, basic oxygen and electric arc furnaces. It is liquid cooled from its molten state and has high density.
Iron and Steel Slag Market: Snapshot. In order to stay ead of the curve in the global iron and steel slag market, keen players are seeking out partnerships with original equipment manufacturers (OEM) in different enduse industries, namely building and construction, railways, fertilizers, etc.
Recycling: Ferrous slags are viewed as valuable byproducts of ironmaking and steelmaking. Apart from the large outside markets for slag in the construction sector, some iron and steel slags are used in the furnaces as ferrous and flux feed. Entrained metal, particularly in steel slag, is routinely recovered during slag processing for return to the
Oct 26, 2017· Albany – NY, Oct. 26, 2017 (GLOBE NEWSWIRE) At the forefront of driving the global market for iron and steel slag is the construction industry and stringent environmental emission control ...
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.
Tangshan Iron Steel, the flagship site of China''s largest steelmaker, Hebei Iron Steel (HBIS) Group, the second largest producer of steel in the world. In recent years Tangshan Iron Steel has made environmental improvements in power consumption, water use and byproduct recycling.
Active Members Member organizations are actively engaged in iron and steel slag processing, refining, and/or the marketing of these slags. Allied Members Organizations involved in servicing or providing products pertaining to the slag producing organizations. Associate Members
This nonmetallic slag material can either be crushed and screened for aggregate use (steel slag aggregates), or sintered and recycled as flux material in the iron and steel furnaces. Steel slag aggregates generally exhibit a propensity to expand.
Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of calcium, silicon, magnesium, and aluminium. Any sandy component or quartz component of the original ore automatically carries through the smelting process as silicon dioxide.
2. Overview of Iron/steel Slag Iron/steel slag production Slag is produced during iron and steelmaking processes, originating from the gangue in the mineral raw materials such as iron ore, coal, and limestone as well as those in the flux used at steel refining processes to remove Si, P, S, and other impurities in molten pig iron or to ...

AirCooled Blast Furnace Slag. Crushed ACBFS is angular, roughly cubical, and has textures ranging from rough, vesicular (porous) surfaces to glassy (smooth) surfaces with conchoidal fractures. There can, however, be considerable variability in the physical properties of blast furnace slag, depending on the iron production process.
SLAG IRON AND STEEL 16 Slag Iron and Steel S lag is a byproduct generated during manufacturing of pig iron and steel. It is produced by action of various fluxes upon gangue materials within the iron ore during the process of pig iron making in blast furnace and steel manufacturing in steel melting shop.
The internal recycling process of BOF slag which is one of the huge solid wastes from iron and steel industry was emphasized. Based on the four scenarios of different internal recycling strategies for BOF slag, life cycle assessment (LCA) as a valuable tool for industrial solid waste management was applied to analyze the contribution to reducing environmental impacts and resources burdens for ...
