INTRODUCTION

IN recent

years, the upper limit for the composition of several elements in liquid steel has decreased significantly. For example, oxygen and sulfur can be controlled below 20 ppm levels. Nitrogen levels must also be controlled, and nitrogen is absorbed from air in many steelmaking processes. However, there is no effective refining technique presently available to remove nitrogen. Vacuum degassing can only remove small amounts of nitrogen when the sulfur content is very low (
