PCT No. PCT/DE95/01521 Sec. 371 Date May 19, 1997 Sec. 102(e) Date May 19, 1997 PCT Filed Oct. 27, 1995 PCT Pub. No. WO96/16190 PCT Pub. Date May 30, 1996A process for blowing oxygen-containing gas, with and without solid material, on a metal melt in a metallurgical vessel, a process for generating a burner flame and corresponding devices. The inventive process and lance suitable for such process provides, without structural conversion and by a simple design, various different process steps in the treatment of metal melts in a metallurgical vessel while increasing the insertion rates of the individual media. This is accomplished using a multifunctional lance in which the process of blowing oxygen with and without solids, and the generation of a burner flame may be performed independently from one another. The individual supply lines are connected in a corresponding manner depending on the respective process step. In the process for blowing oxygen-containing gas, vibrations are excited in the gas flow in a relatively simple manner. |
