The Azovstal' combine studied methods to improve the quality of its large forging ingots. Steel 10KhSND was made in a 350-ton oxygen converter and the mold walls were lined with chrome-magnesite, high-alumina, or fireclay. Nonmetallic inclusions of the trial steel were found to include sulfides, oxides, titanium nitrides, silicates, and aluminosilicates. Usable output increased due to an improvement in the quality of the ingots with a 20-25% reduction in crop and in material and energy costs.
