A533 Grade A steel pipe ladle treatment: short for ladle refining outside the furnace processing type. Is characterized by short refining time (about 10 ~ 30 minutes). A533 Grade A don’t needs compensation of molten steel temperature lowering heating device and process, so the operation is very simple, and it needs less equipment investment.
A533 Grade A steel needs degassing, desulfurization, composition and change the inclusion shape control device. Such as vacuum circulating degasification method (RH, DH), vacuum ladle argon blowing method (Gazid), ladle powder processing method (IJ, TN, SL) as such.
Ladle Refining of A533 Grade A steel pipe: type ladle refining refining outside the furnace. Its characteristic is long than the refining ladle handle (about 60 to 180 minutes), have a variety of refined function, have new methods like compensation A533 Grade A molten steel temperature lowering heating device, suitable for all kinds of high alloy steel and special steel performance (such as super pure steel) refining. Such as the following methods: Vacuum oxygen decarburization process (VOD), vacuum arc heating degassing method (VAD), ladle refining method (ASEA - SKF), enclosed argon blowing composition adjustment method (CAS). And argon oxygen decarburization (AOD) is also similar to the methods above.
