RH Degasser

RH degasser is a secondary refining system that removes dissolved gases such as hydrogen present in molten steel to enable the production of high-grade steel.

Processes that remove the dissolved gases present in molten steel are necessary for the production of high-grade steel. RH degassers (RH) are suitable for quickly degassing from large quantities of molten steel. They feature a vacuum chamber equipped with two snorkels that is mounted to the ladle. Argon gas is blown from the sides of one of the snorkels, circulating the molten steel into the vacuum chamber using the buoyancy of the blown gas and removing dissolved gases such as hydrogen from the molten steel.

NIPPON STEEL ENGINEERING CO., LTD.'s RH degasser is equipped with a Multi Function Burner (MFB). MFB is a device that enables fuel and oxygen to be blown from a single lance that is inserted into the vacuum chamber. It allows heat to be retained within the vacuum chamber both during vacuum processing and while on standby. This reduces the adhesion of metals within the chamber while making it possible to manufacture ultra low-carbon steel by means of oxygen blowing during processing.
