摘要
Disclosed is a method for determining a decarburization time during an RH vacuum degassing process. In one embodiment, the method for determining the decarburization time during the RH vacuum degassing process includes: determining a target value of carbon concentration in molten steel after the RH vacuum degassing process; The immersion pipe of the RH vacuum degassing device is immersed in the molten steel contained in the ladle, and the molten steel is sucked up and refluxed into the vacuum tank to perform decarburization, but the concentration of the mixed gas in the exhaust gas in the vacuum tank reaches 2.0% by volume. A step of first decarburizing until the time point; And further decarburizing according to the target carbon concentration in the molten steel.
