Blast furnace (BF) is the most used equipment for production of iron in world. It charged mainly with metallurgical coke and ferrous materials. When descending inside BF, iron-bearing materials start reducing melting other burden This leads to formation so-called primary slags from which final slag formed as descend furnace. Each charge material has a unique effect on total composition BF slag....

Physical properties of molten slag such as viscosity, density and surface tension have a significant influence on the slag splashing process in an oxygen steelmaking converter. Particularly, viscosity determines the shear forces that rule droplets formation. Besides, stirring of the molten slag bath strongly depends on this property. In this work, the influence of viscosity on the efficiency of...

The purpose of this study was to investigate the reuse of desulfurization slag in cement clinker production and its influence on the formation of clinker phases. The desulfurization slag that mainly contained Ca and Si was identified as non-toxic, and thus it should be suitable to be reused in clinker production. The addition of desulfurization slag increased the melt phase during clinkerizatio...

Alkaline treatment with steel slag and NaOH addition were investigated under different pH conditions for the fermentation of waste activated sludge. Better performance was achieved in steel slag addition scenarios for both sludge hydrolysis and acidification. More solubilization of organic matters and much production of higher VFA (volatile fatty acid) in a shorter time can be achieved at pH10 ...

Two liquid phases: molton metal (or alloy) and slag occur in most metallurgical systems. The slag occurring at the surface of the metal bath not only protects it against negative atmospheric effects but also enables to make many treatments necessary to achieve good quality of the material designed for shaping the casted products. In the conditions of fully controlled process (e.g. melting or re...

Submit Manuscript | http://medcraveonline.com rate of about 125 kg/t of the steel produced which leads to piling of the slag in the plant. This slag is generally recycled in a waste recycling plant (WRP) so as to separate the magnetic and the nonmagnetic portions by means of mechanical crushing and magnetic separation. The magnetic portion is then recycled and used in the primary steel making p...

–The objective of present work is to use this industrial waste i.e. Slag as particulate filler material to the epoxy matrix composites by molding technique with different weight fractions ( 0%, 5%,10%,15%, 20% ) to study the mechanical behaviour of reinforced polymer composite material. The change in weight is studied for Slag under different tests like, tensile, bending and impact for obtainin...
