The steel slag produced during the primary stage of steel production is referred to as furnace slag or tap slag. This is the major source of steel slag aggregate. After being tapped from the furnace, the molten steel is transferred in a ladle for further refining to remove additional impurities still contained within the steel.

If steel mill slag was considered special waste up to a few years ago, today this industrial byproduct is a valid source of recovery of metal and non-metal material. There is a growing demand for aggregates in the construction sector, while quarries are diminishing.

The production of steel in an EAF is a batch process. Cycles, or "heats", range from about 1-1/2 to 5 hours to produce carbon steel and from 5 to 10 hours or more to produce alloy steel. Scrap steel is charged to begin a cycle, and alloying agents and …

Integrated steel plants utilize mostly five materials such as raw materials, air, water, fuel and power to produce steel. During the production of steel, 2–4 t of wastes are being generated per tonne of steel produced.The various solid wastes in the form of slags and sludges that are emerged from steel plants are blast furnace slag, blast furnace flue dust and sludge, …

What is metal slag? The production of high grade steel begins in electric arc furnaces. These use electrical energy to melt down metal scrap and alloying elements. The whole process takes place using electrodes which are lowered into the material and create temperatures of up to 3,500°C.

Slag is a by-product of smelting (pyrometallurgical) ores and used metals, generally. Slag can be classified as ferrous (by-products of processing iron and steel), ferroalloy (by-product of ferroalloy production) or non-ferrous/base metals (by-products of recovering non-ferrous materials like copper, nickel, zinc and phosphorus).

of the steel and into the slag. In modern EAF operations, especially those operating with a "hot heel" of molten steel and slag retained from the prior heat, oxygen may be blown into the bath throughout most of the heat. As a result, some of the melting and …

Using our own special-purpose vehicles, we move slag promptly and efficiently from your production area to the slag beds and, after cooling, to the temporary storage site and our processing plants. We have developed our own efficient logistics system to ensure that the vehicles transporting the slag are always at the right place at the right time.

During the steelmaking process, fluxes that consist of lime (CaO) or dolomitic lime, with iron and scraps, are charged to the furnace.There is a certain amount of free lime (f-CaO) in steel slag. Free lime, with a specific gravity of 3.34, can react with water to produce Ca(OH) 2, with a specific gravity of 2.23, which results in volume increase (Fig. 9.1).

JL Pittsburgh works did slag processing onsite. No fancy dump like USS. The JL process was multiple tracks that would dump into pits between said tracks, water jets were used to quickly cool the slag, steam shovels (later diesel) would break up and load the slag into rail cars and later trucks to be taken to crusher processor onsite.

By minimizing slag carryover into the ladle, the operator lowers the amount of reducible oxides in the slag which must be treated at secondary processing, lowering costs and producing a cleaner steel. The system also acts as a training tool for new operators, and allows for more consistent tapping practices for all operators.
