- Abstract
Methods are proposed for intensifying mass transfer in blow of steel in a ladle using acoustic vibrations. Industrial tests of blowing metal in a ladle using a lance and imposition of acoustic vibrations generated by an external acoustic radiator are described. An acoustic blow plug (ABP) containing a resonator of jet-acoustic vibrations is proposed for argon blow of steel in the ladle. Model studies and theoretical estimates of factors that contribute to intensification of mixing and decrease in the blow plug erosion are described. The results of industrial testing of blowing steel in a furnace-ladle plant using the ABP at the Severskii Pipe Works are presented.
