Iron Slag In this work, the Iron Slag is taken from the Dhiman Iron and Steel industry located at Mandi Gobindgarh, Punjab. It is black in color as shown in figure. The sieve analysis of iron slag is shown in Table 3.6. Magnesium Sulphate The Powder form of Magnesium Sulphate was obtained from Swindra Instruments Corporation, Anand Pura,
Molten steel is prone to oxidation more than molten iron, making deoxidation a necessary step. Conventional methods typically use aluminum, a strong deoxidizer, but it has drawbacks such as low density and floating on slag. Cored wire technology offers an economical alternative by employing deoxidizers like calcium silicate and ferrosilicon.

By adding 20% and 30% iron slag, there is large amount of increase in percentage i.e. 68%, 91%, 78% and 125%, 113%, 87% after 7, 28 and 56 days respectively. Split Tensile Strength After adding 10% iron slag in the mix, …
Steel slag is a by-product generated during the steelmaking process, constituting 15 to 20 % of crude steel production [3].Steel slag possesses significant sensible heat, carbon sequestration potential, and resource utilization capacity, all of which are crucial for reducing CO 2 emissions in the steel industry. Given its high heat content in the molten state, the release of steel slag ...
The slag generated from iron- and steelmaking industry is characterized with high content of lime, magnesia, silicates, and iron (Table 1). Iron and lime are two essential substances in iron- and …
Because iron oxide is not physically present in the resulting slag mass, the slag mass becomes a "dry-like" slag, an asset to clean iron production because it forms a barrier to further molten iron atmospheric contact. And because free oxygen atoms are not resupplied, the bath quickly becomes depleted of free oxygen – that is "deoxidized."
Natural graphite, on the other hand, produces excellent slag volumes but slow reduction of iron oxide. Slower rates of gas generation and higher surface tension values cause slag to trap gases and sustain ing. …
We have experience at several foundries that have successfully used this product with gray iron. Of course, in these cases we have to work only about slag. Even if gray iron is not as dirty as ductile, slag is a considerable concern. For this reason, it is important to minimize slag in gray iron too, and DISPERSIT definitely helps to achieve this.

1 INTRODUCTION. Blast furnace slag (BFS) and steel slag (SS), as industrial solid wastes produced in the process of steel-making, account for 80%–90% of the total smelting slag. [] BFS accounts for about 30% of pig iron output, [] while SS accounts for 10%–15% of the crude steel output. [] SS comprises various slags, including basic oxygen furnace slag (BOFS) …
Slag aggregates. Rendering environmental-friendly provisions, the Slag Aggregate branch of GSW produces well-prepared, top-notch quality aggregates from slag. We can create an iron-free aggregate by use of advanced crushing and magnetic separating methods which can be used for various applications like road making or rail ballast.
Manufacture and quality management of iron and steel slag products are carried out for a broad range of applications. These products have cleared environmental standards, and the majority of them are now provided to the market either as JIS (Japan Industrial Standard) equivalent products or as designated procurement items under the Green Purchasing Law.
