Continuous-casting round and square billets made of carbon and alloy steels with special properties are designed for production of bar-stock pipes and custom products.
Steel is melted in electric arc furnaces with external steel treatment; ladle furnaces with vacuum degassing, argon purging and subsequent casting at continuous steel casting units. Ultra-ductile metal with low content of detrimental impurities and low content of gases and non-metal inclusions is used.
