摘要：
A process for producing an extremely low carbon steel in a top- and bottom-blown converter. The process is characterized in top-blowing a mixed gas of oxygen gas and an inert gas onto a molten steel in the top- and bottom-blown converter. The mixed gas is blown through a top-blowing lance at the final decarburization stage, while a gas (selected from a group consisting of an inert gas, oxygen gas and a mixture of oxygen and an inert gas) is bottom-blown into the molten steel in the converter.
