The re-melted slags, which were left to cool in the crucibles (semi-rapid cooling), resulted in large pieces that were crushed to <4 mm for leaching tests.The water-granulated material of the BOF slag, the EAF slag 1 and the EAF slag 2 consisted of granular particles, 2–4 mm.During the rapid cooling process the ladle slag reacted with …
The EAF slag is the majority of the slag produced in an EAF plant (up to 75 percent). There are two other slag sources in an EAF operation: (1) the ladle slag that is formed by adding slag formers to the ladle, and (2) a pit slag that is formed by spillage and other uncontrolled processes. This ladle slag is generally a calcium aluminate with ...

Production and Processing. An Electric arc furnace (EAF) produces steel by the melting of recycled steel scrap, using heat generated by an arc, created by a large electric current Lime added (as flux) combine with silicates and oxides to form liquid slag. EAF slag has a lower density than steel and therefore floats on top of the molten steel.
Thirty samples of approximately 300 g of EAF slag (named slag-1 to slag-30) were collected on the slag dump surface, up to 10 cm deep, along two 150 m profiles, with a sampling step of 10 m .
