Abstract

A converter for refining raw iron consists in the main of steel plated clad with a refractory material and its inserted bottom has a number of nozzles inclined at an angle to the centre line of the converter. The nozzles consist of two concentric straight pipes which are inclined at 15 degrees relatively to the centre line of the converter, and the outlets of the nozzles are in two rows parallel to the pivoting axis of the converter. Each row of nozzles opens only at about the centre of the converter bottom, and the inclination of the separate nozzles diminishes slightly towards the centre line of the converter. A good mixing of the bath is obtd. and maintained in the end phase of the operation, also, when the generation of CO has largely finished.
