slag powder and blast furnace slag so the recycling of steel slag can bring enormous benefits and environ-mental benefit to whole society.[9] 6. Ground granulated blast furnace slag is commonly used in combination with Portland cement in concrete for many applications[10,11] 7. The heat of hydration is dependent on the Portland

This paper investigates the effect of ferronickel slag powder on microhydration heat, flow, compressive strength, and drying shrinkage of mortar. In South Korea, approximately two million tons of ferronickel slag, a by-product of the nickel industry, are produced every year. However, a considerable amount of this by-product is treated as waste and dumped in landfills.

Yellow gangue, silico and steel slag make use of a belt weigher to measure; however calcium carbide slag and fly ash use the powder rotameter, which may cause the large fluctuation. To maintain the accuracy of measurement, some changes were made: a high precision fly ash rotameter was used and a cushioning device added into the negative ...

Granulated Blast Furnace Slag : Granulated blast furnace slag or gbfs is the residue of combustion in the furnace of the steel refining process. It is obtained by quenching molten iron slag from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.

In subsequent steps, the retort is emptied, the reduced iron sponge is separated from the slag and is crushed and annealed. The resultant powder is highly irregular in particle shape, therefore ensuring good "green strength" so that die-pressed compacts can be readily handled prior to sintering, and each particle contains internal pores ...

Steel - Steel - Ladle metallurgy: The carrying out of metallurgical reactions in the ladle is a common practice in practically all steelmaking shops, because it is cost-efficient to operate the primary furnace as a high-speed melter and to adjust the final chemical composition and temperature of the steel after tapping. Also, certain metallurgical reactions, for reasons of equipment design and ...
