摘要
This invention provides a method for preliminarily treating hot metal which comprises passing hot metal continuously in a trough-like vessel disposed in a horizontal direction towards the downstream side and jetting obliquely downwards a powdered refining agent into the hot metal by use of an oxygen-containing gas as a carrier gas from a single-pipe nozzle disposed on the side wall of the vessel with the nozzle port thereof being positioned below the molten metal surface.
