Secondary Refining steel

any post steelmaking process performed at a separate station prior to casting and hot metal desulfurizaion. It does not include normal alloying prac tice in the furnace or at the ladle during tapping. This definition is not universally applied and many include operations at the tundish, electromagnetic stirring in the mold, etc.get price

Ladle (metallurgy) Wikipedia

Typically a transfer ladle will be used to transfer molten metal from a primary melting furnace to either an holding furnace or an auto-pour unit. Treatment ladle: a ladle used for a process to take place within the ladle to change some aspect of the molten metal. A typical example being to convert cast iron to ductile iron by the addition ofget price
