Abstract

This work was a continuous and multidisciplinary development. Through studies of the blowing process and its parameters results, evolutions, improvements and adjustments were made on the lance’s hot face with Slagless® technology, as well in the process parameters and mitigating actions of the projection of materials out of the converter. The main results are the increase in the nozzle’s life with a “record mark” of 1785 heats, and water leakage occurrence in the cartridge decreased considerably reaching the mark of one year without any occurrence.
