Abstract
A method for regulating the final carbon content in a steel production process that includes oxygen injection, characterized in that the minimum weight condition of the steel load caused by oxygen injection is detected, and the injection is continued oxygen after reaching this condition during a period that allows the injection of a quantity of oxygen that is chosen by a previously established ratio and that is effective in reducing the carbon content to the required level, from that corresponding to the minimum weight condition .
