Abstract
The study reviews an analysis of factory melting of K52 strength grade pipe steel in Casting and Rolling Complex (the branch of OMK) which demonstrates steel quality infl uence factors. As a basis, the authors have taken data set of 30 melting. Analyzed manufacturing scheme includes setting and tapping in an arc furnace, metal production in a ladle furnace and steel degassing adjusted microalloying, ladle inoculation and also hot-rolling with subsequent sheet-shearing and strip-shearing. It is signifi cant that reject key factors perhaps are fragile and rigid silicate non-metallic inclusions. This study also contains recommendations of reducing silicate non-metallic inclusions content for changes in technological process.
