- When steel is initially made, the molten state can have carbon and hydrogen gases trapped within. Older methods to remove the gases involve two days of cooling that consequently affects production time and adds cost to the steel maker's bottom line.
- Steam ejectors use high pressure to bring gases out of the steel mixture. Steam is sent through an ejector at a high velocity. As pressure grows within the ejector, a suction valve placed in the liquid metal is opened to allow gases to be suctioned out. This high powered suction reduces the amount of gases within the steel without the need to cool it.
- For some steel manufacturing, argon gas is also pumped into the molten steel mixture. This promotes turbulence within the mixture to bring the unwanted gases up and out faster than without the argon.
