Abstract

A study was carried out on the refining and modification of steel in a steel-pouring ladle using flux-cored wire grade PP-TM14-FeVAlCa. Steel grade 20GL was used as the test metal. The results of various variants of refining, both traditional and steel processing by combining the operations of deoxidation and desulfurization with flux-cored wire, are presented. The paper presents the results of a study of the mechanical properties of steel grade 20GL for various processing options.
