Blast furnace slag granulation at cast house. Blast Furnaces normally generate 250 to 350 Kg of liquid slag for every ton of hot metal produced. This molten slag is at around 1400 1550 deg C temperature. Till seventies blast furnace BF slag was considered a waste product and was being dumped at a convenient place away from the blast furnace.

The application of ultrafine groundgranulated blastfurnace slag GGBFS in concrete becomes widely used for high performance and environmental sustainability. The form of ultrafine slag UFS used in concrete is powder for convenience of transport and store. Dryinggrindingdrying processes are needed before the application for wet emission.

This paper presents the strength and durability of cement mortars using 0100 ferronickel slag FNS as replacement of natural sand and 30 fly ash or ground granulated blast furnace slag GGBFS as cement replacement. The maximum mortar compressive strength was achieved with 50 sand replacement by FNS. Durability was evaluated by the changes in compressive strength and mass of

2011629The dry process in the case of blast furnace produces a cement grade granulate of equal quality to that produced by the wet process. Hence it has increased value due to reduced energy requirements in subsequent processing. So the dry blastfurnace slag granulation arrangement application can dissolve such problems the dry even sied

The present paper introduces and compares the main processing methods of the steel slag disposal in China. Results show that the steel slag comprehensive utiliation and residual heat reclamation are still in the phase of research and development and havent

2020117Abstract The influence of ferronickel slag powder on the sulfate attack resistance of concrete and the corresponding mechanism were investigated by measuring the porosity and charge passed through the concrete and the compressive strength loss below and after the concrete experienced a drywet cycle in a sodium sulfate solution and immersion in a high temperature sodium sulfate solution.

20151218General Information Blast furnace slag is a byproduct of the steel industry produced by adding a limestone flux to the ironore to remove nonferrous contaminants. Granulated Blast Furnace Slag is obtained by rapid cooling or quenching of molten slag

202035The molten blast furnace slag is quenched almost immediately to form a material generally smaller than a 4 sieve. The efficiency which the molten blast furnace slag is rapidly chilled as well as the chemical composition of the slag source largely determines its

2020323Electric Arc Furnace Slag EAF or steel furnace slag Produced when scrap metal and fluxes are oxidied by the use of an electric current. Molten slag is generally placed into ground bays for cooling. Both BOF and EAF slags are somewhat heavier than Blast Furnace Slag and most quarried rock material. Uses include

201272The slag which has a tapping temperature of around 1500C is normally used as a substitute for cement clinker or as an aggregate material in road construction. The current stateoftheart practice is to granulate molten blast furnace slag in wetgranulation

Ground granulated blast furnace slag GGBS is a nonmetallic product obtained as a byproduct from the blast furnaces used to make iron. Ground granulated blast furnace slag consists of silicates and aluminates of calcium and other bases. The sie of its particles is less than 45 microns and specific surface area is about 400 to 600 m 2 kg.

Blast furnace slag BFS see Wikipedia ground granulated blastfurnace slag is a This process results in the formation of sand sie or fritlike fragments 16 of production is accounted for by semidry and semiwet process

Wet Blast Furnace Slag. Groundgranulated blastfurnace slag GGBS or GGBFS is obtained by quenching molten iron slag a byproduct of iron and steelmaking from a blast furnace in water or steam to produce a glassy granular product that is then dried and ground into a fine powder

Since more than 100 years blast furnace slags are used as additive material or substitute material in cementitious systems like mortar and concrete. Due to their different syntheses the slag systems have binding properties which differ from conventional clinker. With the help of mechanical activation due to fine grinding the properties of blast furnace slags are shifted towards clinker systems.
