Abstract

Consideration of the prototype tuyere geometry for injection of inert gas through the bottom in a basic oxygen steel furnace, and a requirement to specify an optimal flow for bottom wear and metal penetration, led to experimental investigations to apply the results of previous workers to this specific case. Flow velocity profile development within the tuyere was proposed as significant and the experimental scheme was designed to test this. It is proposed that the design criteria of the conditions of optimal flow of the prototype geometry be based on the non-dimensional mass velocity.
