After the oxygen blowing, continue to blow argon and stir, perform carbon deoxidation (both carbon and oxygen in steel are reduced at the same time) and degas under vacuum, and perform sampling and temperature measurement (generally no sampling during oxygen blowing, sampling should be stopped if necessary Blow oxygen). If the temperature is too high, the return material of this steel can be added to cool down, and slagging materials such as deoxidizer and lime can be added, as well as alloy adjustment components, and then continue to vacuum degassing. When the chemical composition and temperature of the steel meet the requirements, it will be cast immediately after processing. Usually the refining time takes about 1h.
