Wrought iron can be melted and cast, however the product is no longer wrought iron, since the slag stringers characteristic of wrought iron disappear on melting, so the product resembles impure cast Bessemer steel. There is no engineering advantage as compared to cast iron or steel.
SLAG IRON AND STEEL 16 Slag Iron and Steel S lag is a byproduct generated during manufacturing of pig iron and steel. It is produced by action of various fluxes upon gangue materials within the iron ore during the process of pig iron making in blast furnace and steel manufacturing in steel melting shop.
For typical iron ore grades (60 to 66 percent iron), blast furnace slag output will be about to metric tons of slag per ton of crude iron produced. Steel furnace slag production, after removal of entrained metal, will be about 10 to 15 percent of the crude steel output.
materials and fuses them into cakes that are 52 to 60 percent iron. Other iron sources are scrap metal, mill scale, and steel making slag that is 20 to 25 percent iron (Lankford et al., 1985). Coke is made in ovens that heat metallurgical coal to drive off gases, oil, and tar, which can be
Steel slag aggregates are highly angular in shape and have rough surface texture. They have high bulk specific gravity and moderate water absorption (less than 3 percent). Table 181 lists some typical physical properties of steel slag. Table 181. Typical physical properties of steel slag.

Mineral Resource of the Month: Iron and Steel Slag EARTH . For typical iron ore grades (60 to 66 percent iron), blast furnace slag output will be about to metric tons of slag per ton of crude iron produced. Steel furnace slag production, after removal of entrained metal, will be about 10 to 15 percent of the crude steel output.
Corrosivity: Blast furnace slag is mildly alkaline, with a pH in nonstagnant water mixtures in the range of 8 to 10. Despite the fact that blast furnace slag contains a small component of elemental sulfur (1 to 2 percent), the leachate is slightly alkaline and does not present a corrosion risk to steel (, steel .

The shape and physical characteristics of iron and steel slag are similar to ordinary crushed stone and sand, however due to differences such as the chemical components and cooling processes, it is possible to provide different types of slag with a wide variety of unique properties.
Having spent more than 40 years in steelmaking, I think I am qualified to answer this question – but WIKIPEDIA has already done a fine job of answering it. WIKIPEDIA defines steel plant slag as: "Basic slag is a coproduct of steelmaking, and is t...
Steel slag also reduces CO 2 emissions because it is calcined in the steel making process. It also saves valuable raw materials for another day and the CO 2 pt that would be emitted from the clinkering process. Another benefit to the cement manufacturer from using steel slag is iron oxide in steel slag needed in the chemistry of Portland cement.
