Recycling Of Blast Furnace Slag


Blast Furnace Slag - Material Description - User

Recycling Pelletized blast furnace slag has been used as lightweight aggregate and for cement manufacture Foamed slag has been used as a lightweight aggregate for Portland cement concrete Granulated blast furnace slag has been used as a raw material for cement production and as an aggregate and insulating material


Blast Furnace Slag - an overview | ScienceDirect Topics

6 Zinc Fuming and Recycling Fuming of lead blast furnace slag is an important source of zinc oxide as feed for zinc electrowinning Slag containing 12–18% zinc is reduced in a water-jacketed furnace at 1150–1200°C by injection of pulverized coal and air through tuyeres


Blast Furnace Slag - Material Description - RMRC

Blast Furnace Slag - Material Description ORIGIN In the production of iron, iron ore, iron scrap, and fluxes (limestone and/or dolomite) are charged into a blast furnace along with coke for fuel The coke is combusted to produce carbon monoxide, which reduces the iron ore to a molten iron product


Blast Furnace Slag Cement - theconstructororg

Blast furnace slag cement is the mixture of ordinary Portland cement and fine granulated blast furnace slag obtained as a by product in the manufacture of steel with percent under 70% to that of cement Ground granulated blast furnace slag cement (GGBFS) is a fine glassy granules which contain cementatious properties


Discussion of blast furnace slag recycling of a factory

Discussion of blast furnace slag recycling of a factory Abstract: A large amount of solid waste slag is generated in the production process in iron and steel enterprises As for enterprise which takes blast furnace as the process, blast furnace slag accounts for more than 50%


RECYCLING OF STEELMAKING SLAG - academiaedu

RECYCLING OF LD-SLAG The phosphorus content of the blast furnace usually ranges from 01 to 03 % depending upon the type of burden used, whereas the bulk of quality steels must have phosphorus level below 002% Table 8 shows the effect of recycling of dephosphorised slag on the phosphorus values of hot metal


Blast Furnace Slag | National Slag Association

Blast Furnace Slag is formed when iron ore or iron pellets, coke and a flux (either limestone or dolomite) are melted together in a blast furnace When the metallurgical smelting process is complete, the lime in the flux has been chemically combined with the aluminates and silicates of the ore and coke ash to form a non-metallic product called blast furnace slag


Blast Furnance Slag - User Guideline - Portland Cement

ENGINEERING PROPERTIES Fineness: Granulated blast furnace slag is a glassy granular material, and its particle distribution, shape, and grain size vary, depending on the chemical composition and method of production, from popcornlike friable particles to dense, sand-size grains Pelletized blast furnace slag, in contrast to air-cooled


Ground granulated blast-furnace slag - Wikipedia

Silicate and aluminate impurities from the ore and coke are combined in the blast furnace with a flux which lowers the viscosity of the slag In the case of pig iron production the flux consists mostly of a mixture of limestone and forsterite or in some cases dolomite


Ground Granulated Blast Furnace Slag in Concrete and its

The ground granulated blast furnace slag (GGBFS) is a by-product of iron manufacturing which when added to concrete improves its properties such as workability, strength and durability This material is obtained by the heating of iron ore, limestone and coke at a temperature about 1500 degree
