nickel iron granulated slag processing stainless steel,Euronickel produces high quality low carbon ferronickel granules comprising approximately 20 nickel and 80 iron that are primarily used in the production of stainless steel Our ferronickel is shipped in bulk or in bags from North Macedonia to major steel makers in Europe and internationally

CNB

The invention relates to a technique for smelting stainless steel, and particularly relates to a novel technique for smelting stainless steel through an RKEF (rotary kiln-electric furnace) and AOD furnace duplex process. The technique comprises the following steps: directly feeding crude nickel alloy molten iron produced by an RKEF into an AOD furnace, performing duplex refining to produce ...

What is called "Argon Oxygen Decarburization (AOD) Process"

Ground Granulated Blast furnace Slag as the name suggests is granulated blast furnace slag, ground to very high fineness Granulated blast furnace slag is obtained during the manufacturing process of pig iron in blast furnace When the molten slag at degC is tapped and subjected to a special process of quenching it.

(PDF) Ferronickel Slag Uses and Environment

During the pyrometallurgical treatment of the nickel-bearing laterite in the plant of G.M.M. S.A. LARCO, slag is produced after treatment in electric-arc furnace (EAF) that contains 0.10 to 0.20 % Ni.

Iron

2. Overview of Iron/steel Slag 2.1 Iron/steel slag production Slag is produced during iron and steelmaking processes, origi-nating 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 re-fining processes to remove Si, P, S, and other impurities in molten pig iron or to ...

Copper slag is used for cleaning surfaces made of steel, removing of paint coatings, rust and scale. It is commonly used for restoration of thin and thick steel construction, heavily painted or corroded steel bridges, ship hulls, steel and concrete production platforms, installations on oil fields, pipelines and all offshore and maritime applications.

Slag

There are several different types of steel slag produced during the steel-making process. These different types are referred to as furnace or tap slag, raker slag, synthetic or ladle slags, and pit or cleanout slag. Figure 18-1 presents a diagram of the general flow and production of different slags in a modern steel plant.

The optimal process for preparing road Portland cement with nickel slag is: the contents of nickel slag, limestone, fly ash, steel slag, desulfurized gypsum, and calcium fluoride (weight percentage) are 14%, 74%, 4%, 7%, 0.6% and 0.4%, respectively; the calcination temperature is 1350 °C and the heat preservation time is 60 min.

from iron ore to steel manufacturing process

Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore.Slag is usually a mixture of metal oxides and silicon dioxide.However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of ...

Fe

The slag has a lower density than steel and therefore floats on top of the molten steel. Once the steel has been tapped into a ladle, the slag is either poured from the furnace onto the floor where it is cooled and removed for further processing, or into slag pots where specially designed vehicles are used to transport the slag to purpose built ...

Iron

Each kg of FeNi nickel is providing approximately 5 to 6 kg of clean iron. The addition of iron has big advantages to steelworks. The cooling effect in stainless steel process is significantly low and much lower than stainless steel scrap or other nickel forms.

Nickel processing

The metallic and slag phases are removed systematically from the furnace. The metallic phase for further treatment, nickel enrichment and refinining and the slag for side exploitation and dumping.
