ABSTRACT:
Skulls which form within the upper nose section of steelmaking vessels are removed by means of a centrally located top blowing lance designed to blow at high velocity oxygen or other gases. The lance includes laterally extending ports communicating with a central relatively wide gas chamber and the gas is directed generally laterally outwardly against the inner wall of the nose section to retard or remove the skulls.
