Abstract
The paper analyzes the production technology of corrosion-resistant 08Kh18N10T steel to determine the causes of overgrowth of steel filling cups and contamination with non-metallic inclusions. In the course of the work, the oxygen content found in various types of nonmetallic oxide inclusions and the total nitrogen and oxygen content in the metal were determined at the stages of bucket processing and casting of steel. The results of the electron microscope study confirmed the results of the FGA, namely, the predominance of unfavorable nonmetallic inclusions for corrosion-resistant steels: titanium oxides and nitrides, aluminates and spinels. It is shown that after the titanium wire was recoated into the metal, titanium oxides were the main type of HB. It is shown that the causes of overgrowth of steel filling equipment are complex non-metallic inclusions based on titanium oxide, which «stick» to the inner surface of the steel filling cup dispenser when casting steel.
