determined in order to define the influence of ladle furnace slag on the environment. The final results showed that the ladle furnace slag does not contain constituent which might in any way affect the environment harmfully. The activity concentrations of 226Ra, 232Th and 40K in ladle furnace slag were
TORPEDO LADLE The increasingly severe conditions imposed in high capacity (200 to 500 MT) Torpedo Ladles today are a function of the weight of metal, temperature, transportation time and distance, thermal cycling rate, amount and composition of slag and any metal treatment carried out in the ladle.
amount of furnace slag into the ladle is slag skimming in combination with a tilting ladle car equipped with an EMS. At slag raking, the slag will be pushed towards the slag rake side under the electromagnetic force, move the steel upwards on the stirrer side of the ladle and make the slag removal more efficient and thorough. Figure 3.
Nov 08, 2014· Steel Teeming Ladle and its Refractory Lining Steel teeming ladle (STL) is needed in a steel plant to contain and transport liquid steel from the steel making furnace to the casting facility. These days STL is used in a significantly more complex manner than the older steel melting shops where ladles were used simply to transport liquid steel ...
The variation in composition and properties of blast furnace slags are largely determined by the gangue in the ore and ash in the coke and much progress has been made in the reuse of such slag. With respect to steelmaking slag, emphasis has in recent years been placed on hot metal treatment before refining and ladle treatment after ...
Hot Metal Handling Equipment Remso designs and manufactures Hot Metal Handling Equipment for Steel Plants, Ladle Transfer Car, Coils Car, Hot Slab Transfer Car, Billet Transfer car, Scrap transfer car, Scrap Charging System, Tundish Car, Ladle Car, EOT Crane, heavy duty Electric Over Head (EOT) cranes for application in Steel Plant and Core Sector.

Analysis of the application of ladle furnace slags from steelworks, of low and high alumina, in masonry mortars 1TECNALIASustainable Construction (SPAIN), 2UPV/EHU – ETSI Bilbao (SPAIN), *Corresponding author Abstract Ladle Furnace (basic) Slag (LFS) byproducts from the steel industry are generated after the basic refining of steel.
Slag Composition: The composition of furnace and ladle slag is often very complex. The slags that form in electric furnace melting result from complex reactions between silica (adhering sand and dirt from casting returns), oxides from scrap, other oxidation byproducts from melting and reactions with refractory linings.
Lime plays a key role in fine tuning steel chemistry, lowering oxygen content, removal of impurities such as sulfur and reduction in inclusions trapped by the basic slag. In stainless steelmaking lime is used in the Argon Oxygen Decarburization Furnace (AOD), Lime is used in these secondary processes, Ladle Metallurgical Furnace, (LMF) and ...
Ladle. Steel Ladles are being operated for longer continuous periods while minimizing downtime for maintenance or repair. In addition, an everincreasing number of metallurgical operations are now being performed in the ladle as opposed to the furnace.

The argon oxygen decarburization (AOD) process is used to make stainless steel and specialty grades of steel, including tool steels, silicon steels, lowalloy steels, and lowcarbon steels. In this process the tuyeres are submerged, resulting in high element recovery, rapid and efficient desulfurization, and good control of the slag chemistry.
Iron and steelmaking slags (ferrous slags) are coproducts of the iron and steel making industry. They are nonmetallic rocklike materials which are produced together with the metallic products of these processes. Depending on the iron and steel production process different slag types can be manufactured. Blast furnace slag is made during the melting and reduction of iron [.]
These custom designed additives quickly generate a fluid ladle slag to improve shop productivity and final product quality. The generation of a liquid ladle slag with high CaO (Calcium Oxide) and low FeO (Iron Oxide) contents increases the absorption capacity of both oxide inclusions and sulfur.

It was shown that the application of the secondary metallurgy by a synthetic slag in the ladle furnace and argon bubbling of a metal bath leads to obtaining in the final analysis: % of sulphur (a decrease of S content during refining in LF reached 40%).
May 01, 2009· Characterization of ladle furnace basic slag for use as a construction material Characterization of ladle furnace basic slag for use as a construction material Setién, J.; Hernández, D.; González, 00:00:00 The use of ladle furnace basic slag (LFS) as a cementitious material in industrial applications requires an indepth knowledge of its characteristics.
The refining slag is a new type steel casting auxiliary materials to meet the requirements for producing low sulphur steel. Its raw materials are fused by the EAF, making this products with 90% 7Al2O3•12CaO calcium aluminate contents. Its activity coefficient is more than 70%.
Slag ladle is also called slag pot, casting ladle, or slag bucket. It is important container holding high temperature liquid steel slag in the process of steel making, the main structure contain parts of tank, lug, supporting foot, tilting arm etc.
These include furnace or tap slag, raker slag, synthetic or ladle slags. Figure 1 presents a diagram of the general flow and production of different slags in a modern steel plant. Following processing and metal recovery, the nonmetallic products from the furnace, raker and ladle slags
CHAENG slag pots /slag ladle introduction: CHAENG cast steel slag pots/slag ladle are available with finished weights range from 1– 150 tons. CHAENG has the capability to cast slag pots in nearly every shape and style for a variety of mounting systems and methods of transport. CHAENG slag pots /slag ladle applications:
Submerged arc furnace stoker machine, which is operated remotely (behind blast wall/etc.) and removes operators from heat/potential harm. Dramatically reduces maintenance cost associated with legacy equipment used in this application.
