    Types of iron and steel slag NIPPON SLAG ASSOCIATION

    Blast furnace slag. Blast furnace slag is recovered by melting separation from blast furnaces that produce molten pig iron. It consists of non-ferrous components contained in the iron ore together with limestone as an auxiliary materials and ash from coke. Approximately 290 kg of slag is generated for each ton of pig iron.

    Figure 11 displays that the separation efficiency of molten iron from the slag could be 100 when the height difference between iron dam and slag port is 0.2 m in this work. In contrast when the height of iron dam is increased the interface level will be elevated in the trough resulting in the molten iron flowing into the slag port easily.

    EAFS is produced in an Electric Arc Furnace. The slag is dark grey in colour and is characteristically harder than blast furnace slag BFS. It has a density about 20 - 25 greater than basalt or BFS. It crushes to a cubical shape. EAFS in common with most steel slags is subject to slight dimensional expansion until it fully hydrates.

    The bulk density of asphalt mixes with EAF slag aggregates is 15-20 higher than conventional mixtures on account of the high specific gravity of the slag. Slag mixtures usually show higher void contents because of their the high angularity of their particles which generates higher voids in the mineral aggregate.
