Method and apparatus for continuously treating a mass of molten metal with a determinate treating agent, wherein the treating agent is continuously introduced in a treating vessel through a supply passage formed through the wall of the vessel while the molten metal is continuously poured into the vessel, for effecting a continuous contact of the molten metal with the introduced treating agent. The molten metal is discharged from a lower part of the vessel after it has been treated with the treating agent in the vessel. The treating vessel has a reaction chamber to which the supply passage is open. The treating vessel is adapted so that the poured molten metal which flows through the vessel temporarily stay in the reaction chamber for effective contact and reaction between the molten metal and the treating agent.
