RH Snorkel: A Critical Component in Steelmaking
Understanding RH Snorkels An RH snorkel, or ladle refining snorkel , is a crucial piece of equipment used in the steelmaking process. It plays a vital role in the ladle refining process, where molten steel is refined to achieve the desired chemical composition and properties. The Function of RH Snorkels Gas Injection: RH snorkels are used to inject inert gases, such as argon or nitrogen, into the molten steel. This process, known as argon oxygen decarburization (AOD), helps to remove impurities like carbon, oxygen, and sulfur from the steel. Vacuum Degassing: The snorkel can also be used to create a vacuum above the molten steel. This vacuum helps to extract dissolved gases, such as hydrogen and nitrogen, from the steel, improving its quality and reducing the risk of defects. Powder Injection: In some cases, powders, such as lime or dolomite, can be injected through the snorkel to adjust the slag composition and control the oxid...
