RECYCLING OF STEELMAKING SLAG P.N. Chaudhary J. Pal D.P. Singh M. Singh S. Ghosh ABSTRACT While the usage of blast furnace slag is well established in the area of cement making, recycling of steelmaking slag is still a challenging task. About 150-180 kg steelmaking slag is generated per ton of steel depending upon the quality of hot metal.

Greatest effectiveness of magnetic separation on upgrading steelmaking slag fines occurs below 1000 G surface magnetic field strength, and especially below 500 G. Citations of dry magnetic separation of steelmaking slag fines with near …

Induction Furnace and Steelmaking. Induction furnace is a type of furnace for steelmaking which uses electrical energy for its operation. Induction furnace (IF) steelmaking is one of the two electrical steelmaking processes. The other process for electrical steelmaking uses an electric arc furnace (EAF). Though IFs are being used since a long ...

Steel slag is commonly used to cover driveways, to fill potholes, repair farm lanes, residential entrances, or yards. Steel slag is not just good for driveways, it is also used by homeowners as a landscaping stone in back yards around a pool area or patio.

Liquid slag from the steelmaking furnace is dumped, cooled, and processed to recover the metallics in the slag. The slag fraction is further crushed and screened to produce SSA. Slag processors may handle· a variety of materials, such as steel slag, ladle slag, used refractory and pit slag, to recover steel metallics. These materials ~

For chemical uses, such as a raw material for manufacture of glass or mineral wool insulation and for agricultural applications, the chemical composition is quite important.STEELMAKING SLAGS Steelmaking slags are the by-products of processing molten iron into a specific type or grade of steel.

The history of the modern steel industry began in the late 1850s. Since then, steel has become a staple of the world's industrial economy. This article is intended only to address the business, economic and social dimensions of the industry, since the bulk production of steel began as a result of Henry Bessemer's development of the Bessemer converter, in 1857.
