literature on the topic and details the methodology and experimental setup used in recent studies on phosphorus equilibrium between liquid iron and slags New data for BOF type slags are presented where equilibrium was approached from both metal and slag sides phosphorus was transferred from metal to slag and vice versa
As one of the important industries in the world iron and steel industry plays an irreplaceable role In 2016 the world s crude steel output reached billion tons [1] On average each ton of steel production could accompany with tons of CO 2 emissions [2] Globally CO 2 emissions from iron and steel industry account for about 6 7 % of global CO 2 emissions [3]
The present paper encompasses the existing literature on the workability characteristics of concrete made with IS as an NFA supplant of steel slag Therefore ground steel slag could be utilized as cement additives and concrete admixtures [18] The iron slag IS in concrete satisfies the physical characteristics because of its morphology
As an industrial byproduct of smelter operations smelting slag has brought certain environmental issues including without taking safety precautions or using appropriate management Through a thorough analysis of the literature published in the last years the latest research progress on the characteristics resource utilization pathways and safety utilization
Welcome In 1990 various members representing producers processors marketers customers and suppliers of iron and steel slags founded the Australasian iron & steel Slag Association ASA Adopting a similar operating model used by the National Slag Association based in the USA the ASA has since forged its own operating model and governance structure to meet the
Although the phosphorus reaction in steelmaking has been extensively studied it continues to be a relevant topic as low phosphorus iron sources become less available and more expensive necessitating the need for more accurate predictions of the partitioning of phosphorous as function of slag composition and temperature The current study revisits some of the
split tensile strength of concrete with various percentages of iron Slag Aggregate The result has been found from the various tests which were compared with conventional concrete Thus the use of iron slag in concrete could enhance the strength in concrete Keywords Natural coarse aggregate Iron slag Iron slag aggregate concrete

The underlying vision of the ASA is to serve as an authoritative and credible central reference point for its stakeholders on all matters relating to the iron and steel slag industry Mission The ASA declares as its mission the promotion of the effective and beneficial use
In the two last decades world production of pig iron and steel has undergone a significant increase In 2018 and million tons of pig iron and steel respectively were produced
Industrial waste products from iron and steel manufacturers are known as iron slag An incorporated steel plant produces 2 4 tons of waste total consisting of solid liquid and gaseous waste for every tonne of steel produced [8] Slag production in the iron and steel industry is so great that managing it has turned into a dangerous step in the production process
Globally Gt of steel was produced in 2014 creating 250 Mt of steel slag as residue [] Disposal of the slag is the major issue for steel industry and the utilization of steel slags has been under active research in many years [] Most of the slag 50% is used for road projects sintering iron making and recycling within the steel plant []
A major difference between the NFM slags and other more commonly used SCMs is the high iron content in these slags [15] thereby yielding a higher Fe/Si Fe/Ca and Fe/Al ratio compared to conventional SCMs such as blast furnace slag or fly ash which could have an impact on the phase assemblage of hydrated Fe forms of typical cement
Although the phosphorus reaction in steelmaking has been extensively studied it continues to be a relevant topic as low phosphorus iron sources become less available and more expensive necessitating the need for more accurate predictions of the partitioning of phosphorous as function of slag composition and temperature The current study revisits some of the
The iron and steel slag is characterized by highly alkaline nature and significant levels of metal ions especially Ca According to Geological Survey USGS 2018 every year almost 15 20 million ton of iron/ferrous slag and about 10 15 million ton of steel slag is produced These large quantities of slag are often stockpiled in huge
The ASA has through a refined supply chain approach to sustainability and low carbon product development worked closely with Victorian steel companies and supply chain partner industries to explore or in some cases re explore opportunities to utlise EAFS
Process of slag Generation During the process of reducing iron ore through coke in a blast furnace blast furnace slag is generated while steel making slag is generated in the process of
the possibilities of using iron slag as partial replacement of fine aggregate sand by iron slag Iron slag was used to replace 25% to 30% of sand by weight at increment of 5% for both cube and cylinder The strength of concrete increases rapidly with increase the iron slag content and the optimum value of
