The Potential of Ladle Slag and Electric Arc Furnace Slag ...
The blast furnace (BF) iron slag, also known as a ground granulated blast furnace slag (GGBFS), the electric arc furnace carbon or stainless steel slag (EAF-C/S), and the ladle furnace basic slag (LS), also called the white slag, have been regarded as precursors which exhibit good mechanical properties following alkali activation and can be ...
Handling of Hot Metal in Blast Furnace Iron Making – IspatGuru
blast furnace, Hot metal, hot metal runner, ladle, lime milk, PCM, Pig iron, skimmer, slag, Torpedo ladle Handling of Hot Metal in Blast Furnace Iron Making Hot metal (HM) is produced by the reduction of descending ore burden by the ascending reducing gases in a blast furnace (BF). It is liquid in nature and gets collected in the hearth of the BF.
Ladle Furnace Lining Refractory | Transfer Molten Steel ...
A ladle furnace (LF) also known as a transfer ladle utilizes the roof and most like a typical EAF utilizing an 8 to 25 megavolt ampere transformer, three electrodes for arc heating with the ladle acting as the furnace shell. Ladle furnaces are utilized to relieve the primary melter of secondary refining.
LADLE REFINING AND SLAG CONDITIONING
In the blast furnace slag originates from the gangue in the ore, ash in the coal, and the fluxes (lime, doloma, Al2O3) that were added to melt the gangue and coal ash so that the slag can be tapped from the blast furnace.
Ladle Furnace - an overview | ScienceDirect Topics
Except for heating ladle furnace is an excellent place to make desulfurization with slag, Ca-treatment, and other alloying and trimming additions. The process outline from converter to ladle furnace, vacuum treatment, and casting is presented in Figure 1.6.19.
Recycling of ladle furnace slags - Research Online
Recycling of ladle furnace slags Abstract Ferrous industry slag is waste product of all steelmaking manufactures. These materials should be reused or stocked. There is abundant literature on the subject of reuse and recycling of blast furnace(BF), basic oxygen furnace(BOF), electric arc furnace(EAF).

Optimization of Steel Production: Ladle Furnace Slag and ...
composition and properties of slag play an important role in protecting furnace refractories. The research focused on the development of a slag model to have optimum slag saturated with MgO for better refractory life. A computer model was developed to calculate minimum MgO required during the ladle refining process. The effect of the
SAFETY GUIDELINES FOR IRON & STEEL SECTOR BLAST …
In the Furnace Hot Metal, (along with slag) is processed from the raw material which gets collected in the hearth and blast furnace gases come out of blast furnace from the top. ii) Cast House: In the Cast House Hot Metal , & slag are tapped from the Furnace tap hole and Hot metal and slag are separated in the refractory lined main iron trough.
LEGO IDEAS - - Blast Furnace
At the base of the furnace are two exits. The slightly higher located one is to extract the waste product, the slag. This flows into a slag ladle for further transport. Slag is often used for driveways. The lower located exit is used for the molten iron which flows to the torpedo wagon. It is then transported to an iron mill for further processing.

Canadian Slag Association
Blast Furnace Slag has been used in Canada as a road and plant base material since the early 1900s. Steel Slag was originally used in the 1970s and and consisted of premium surface course HMA. There was extensive use in 1980s and by the 1990s there was in excess of 488,000 tonnes consumed in a variety of applications.
