blast-furnace slag—produce freshly mixed normal-weight concrete with a density (unit weight) of 2200 to 2400 kg/m. 3 (140 to 150 lb/ft. 3). Aggregates of expanded shale, clay, slate, and slag (Fig. 5-3) are used to produce struc-tural lightweight concrete with a freshly mixed density ranging from about 1350 to 1850 kg/m. 3 (90 to 120 lb/ft. 3).

The molten slag, is water-quenched rapidly, after the molten iron is trapped off which results in the formation of a glassy granulate. The molten slag consists of mainly siliceous and aluminous residue. This glassy granulate is dried and ground to the required size, which is known as Ground Granulated Blast Furnace Slag (GGBFS).

If a good ing slag cannot be sustained then however, it is preferable to reduce the secondary voltage and thus the arc length in order to avoid the risk of damage to the furnace structure. The slag ing phenomenon is dependent on the properties of the slag and the gas evolution rate, due to reactions in the slag.

Thanks for your info Tommyjoking, but the slag came from Submerged Arc Welding as you know it generates a huge amount of slag. In history, we normally crushed the slag to consider as Recovered, mixed it with Flux (25% Recovery and 75% ) and used it in production, but we stop that practice due to Customer requirements and related quality issues.
