A method for refining liquid melts involves blowing down with refining inert gas of the metal through the immersed tuyere with simultaneous displacement thereof in the course of blow down and processing with refining reagents. Processing liquid metal with gaseous or gaseous and powdered refining reagents is performed in the flow of gaseous oxygen mixture, and slag is processed only with flows of gaseous oxygen fuel mixture. In the course of processing the tuyere is repeatedly moved in liquid metal and slag with simultaneous change of gaseous oxygen mixture composition and shape of torch for combustion thereof, and also change of gaseous oxygen or gas-powdered refining reagents consumption.
