Different silica sources, used for this investigation to reduce the slag basicity, are quartzite ...
CHARACTERIZATION OF LADLE FURNACE SLAG FROM THE .Ladle furnace slag samples were prepared for EDS analysis as follows: 4 grams of each powdered sample (particle size less than mm in diameter) was pressed into pellets of 20 mm in diameter (15 tons pressure, 30 s dwelling time). No binder material was applied. The samples were placed in standard sample holders and loaded into the spectrometer. Samples were irradiated by Xrays generated ...
Properties and Uses of Steelmaking Slag – IspatGuru · The slag generated in the basic oxygen furnace (BOF) and electric arc furnace (EAF) is of basic nature while the slag is of acidic nature in induction furnace because of the use of silica ramming mass as the lining material. Since most of the steel produced in the world is by BOF and EAF processes, hence slag from these processes is discussed in this article.

WasteFree Recycling of Metallurgical Slags · Extracting clinker from ladle slag is a complex technological process compared to obtaining pig iron from electric furnace slag. Considering this factor, the scientists initially evaluated the conditions such as the temperature levels needed to produce clinker and the chemical composition of the mixture to be processed (charge).
Properties of Ladle Furnace Slag for Their Utilization as ...The ladle furnace slag, as detailed above, was taken directly from the production company. It has then been subjected to a drying process at 105 2 C for 24 h to eliminate the humidity. The elimination of water was carried out in order to avoid variables that would disturb the final results. However, the existence of humidity within an industrial process in which ladle furnace slag is used is ...
Recycling of ladle furnace slagsof ladle furnace slags as a part of ladle fluxes can be considered as an economical recovery for these materials. In current study, the LF slags of Mobarakeh Steel Company (MSC) was separated from metallic part and also was crashed and sized. This powder was blended with some minerals in order to meet different chemical composition of synthetic fluxes. Plant trials were conducted to illustrate ...
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
The Study of Ladle Furnace Slag as Cementitious MaterialSetién et al (2009) stated that ladle furnace slag is produced in the final stages of steelmaking, when the steel is desulphured in the transport ladle, during what is generally known as the secondary metallurgy process. It is determined that LFS contains high amount of calcium and magnesium oxide and low content of ferrous oxides. Silicon and aluminium oxides constitute the other main oxides ...
