Switching gear, electronic hardware, wrought products, and wire. such slag may contain alloying elements e.g., beryllium or iron. beryllium is toxic, and iron is easily oxidized to rust, which appears as spots on the abrasive-cleaned steel surface. the heavy metal content of the coal or furnace
Granulated blast furnace slag or gbfs is a by product of steel plant. the slag is a sand like substance produced by spraying high-pressure water jets on a blast furnace molten slag. when this slag is grounded, it becomes ground granulated blast furnace slag or ggbfs, which is a hot product for ready mix concrete units to produce concrete.
2001 by slag cement manufacturers and the slag cement association, the american concrete institute officially reviewed and changed the terminology from ggbfs to slag cement aci committee 233, 2004. the term slag cement will be used throughout this paper when referring to finely-ground granulated blast-furnace slag.
The molten slag, is water-quenched rapidly, after the molten iron is trapped off which results in the formation of a glassy granulate. the molten slag consists of mainly siliceous and aluminous residue. this glassy granulate is dried and ground to the required size, which is known as ground granulated blast furnace slag ggbfs.
Granulated blast furnace slag gbfs brief description . gbfs is formed when molten blast furnace slag bfs is rapidly quenched from the furnace, rather than left to slowly solidify by air-cooling.. physical description. on casual examination, gbfs would pass for river sand
Slag ground granulated blast-furnace slag fig. 3-5, also called slag cement, is made from iron blast-furnace slag it is a nonmetallic hydraulic cement consisting essentially of sili-cates and aluminosilicates of calcium developed in a molten condition simultaneously with iron in a blast furnace. the molten slag at a temperature of about 1500176c
Jan 31, 2008nbsp018332slag also often has a more glass-like appearance. since slag is just the impurities that are present in the bog iron ore prior to separation in the furnace, it can vary widely depending on the mineral makeup of the particular ore being refined.
Iron blast-furnace slag blast-furnace slag is defined by the american society for testing and materials as quotthe non-metallic product consisting essentially of silicates and alumino-silicates of calcium and other bases that is quotdeveloped in a molten condition simultaneously with iron in a blast furnace.quot the blast furnace is the primary means ...
The slag has a lower density than steel and therefore floats on top of the molten steel. once the steel has been tapped into a ladle, the slag is either poured from the furnace onto the floor where it is cooled and removed for further processing, or into slag pots where specially designed vehicles are used to transport the slag to purpose built ...
Gbfs granulated blast-furnace slag is obtained by quenching molten iron slag a by-product of iron and steel-making from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.it is suitable for applications in marine environment, mass concreting and sulphate environment, water retaining structures, basement and other ...

Jan 10, 2014nbsp018332slags are one of the most natural products of all. slags are principally divided into blast furnace slag and metallurgical slag. at voestalpine the slags resulting from the steelmaking process are separated into blast furnace and metallurgical slags and then recycled. the separated slags are processed into valuable products.
Iron blast furnace slag gbfs is produced by directing the stream of molten slag leaving the furnace into a large volume of cold water in a granulator. the rapid quenching or chilling prevents crystallization and converts the molten slag into sand-sized particles of predominantly amorphous or non-crystalline
