pig iron (hot metal) is flushed out in slag pot and then sent to slag granulating plant or to cooling pits. Depending upon the cooling process, three types of slags are generated; namely, air -cooled slag, granulated slag and expanded slag. Air-cooled slag is produced by allowing the molten slag to cool under atmospheric conditions in a pit.
