electric arc furnace demetallized slag into electric arc furnace charge. The results are as follow 1. Industrial experiments with recycling of demetallized EAF slag into EAF charge showed the additions of demetallized slag had no negative effects on smelting process parameters, on composition and cleanness of produced steel. 2.

The slag is porous and is easy to grind. Under identical loading conditions in a laboratory ball mill, the treated slag takes only half the time to attain a fineness of 400 m 2 kg1 than that of untreated EAF slag. Microstructure The microstructure of the EAF slag before and after heat treatment is given in Figure 4.

A good slag practice is essential for production of a highquality stainless steel. In addition, the electrical and material efficiency of the electric arc furnace EAF can considerably be improved by a good slag practice. The metallurgical properties of the slag are strongly influenced by its hightemperature microstructure.

This Flux Slag can now be crushed reprocessed into a reusable SAW consumable. The S.A.W. flux slag crushing program at Harberts consists of the following 1. A manufacture of the slag ships a LOT of their slag to Harberts. 2. The slag is received and is inspected for deficiencies, and or nonconforming material. 3.

Electric arc furnace slag is produced during the manufacture of crude steel by the electric arc furnace EAF process. In this process steel scrap with additions of fluxes e.g., limestone andor dolomite are heated to a liquid state by means of an electric current. During the melting process the fluxes combine with nonmetallic scrap components and

Electric arc furnace carbon steel slag is a byproduct of the manufacture of steel by the electric arc furnace process EAF. Production and Processing. An EAF produces steel by the melting of recycled steel scrap, using heat generated by an arc, created by a large electric current. The slag is formed through the addition of lime, which is

The mineral composition of blast furnace slag generally consists of melilite Ca 2 MgSi 2 O 7 Ca 2 Al 2 SiO 7 and merwinite Ca 3 MgSi 2 O 8.Steelmaking slag BOS or EAF mainly consist of dicalciumsilicate Ca 2 SiO 4, dicalciumferrite Ca 2 Fe 2 O 5 and wuestite Fe 1 x y,Mg x,Mn yO z.. The physical properties of iron and steel slags depend on the chemistry as well as the cooling

The chemical composition of the waste aggregates is summarized in Table absorption and density of natural aggregates and slag waste were evaluated according to UNI EN 10976 .EAF granulated slag showed higher density than natural aggregates as a consequence of their high iron content 20 30 vs weight.

Electric Arc Furnace Slag EAF or steel furnace slag Produced when scrap metal and fluxes are oxidized by the use of an electric current. Molten slag is generally placed into ground bays for cooling. Both BOF and EAF slags are somewhat heavier than Blast Furnace Slag and most quarried rock material. Uses include

Slag formers are either charged with the scrap or blown into the furnace. The Si and Al in the scrap are oxidized first to form SiO 2 and Al 2O 3 fluxing oxides. As oxygen is blown into the furnace, the principal flux FeO is generated. The 34slag balance34 now starts to shift and the slag becomes more liquid.

The selective crushing capabilities of these machines take advantage of the huge difference in elastic modulus of the minerals and metals in the slag. The appropriate BHS machine, rotor impact mill type RPMV, rotor centrifugal crusher type RSMX or Rotorshredder type RS, depends primarily on the grain size of the input material.

1. PRODUCT NAME 2. MANUFACTURERS Producers of steel furnace slag aggregates for base course and subbase construction applicable under either rigid or flexible pavements can be contacted by visiting the NATIONAL SLAG ASSOCIATION at www.. DESCRIPTION Composition Steel slag is the byproduct of steel making.

Electric arc furnace slag and its use in hydraulic concrete. It is a stony material that is easy to crush for use as aggregate in concrete mixes. This study examines the longterm aging
