Steel in Translation Aims and scope

Abstract

The possibilities of achieving a low carbon content (less than 0.002%) under the conditions of converter production of cold-rolled non grain-oriented electrical steel of the 4th alloy steel group (Si > 2.9% and Al > 1.0%) are studied. With the results of the analysis of the change in the carbon content after decarburization on the circulation degassing plant of the converter shop no. 1 (CDP CS-1), laboratory studies and theoretical calculations are presented. The possibility of achieving a carbon content of less than 0.002% wt. after decarburization in the CDP CS-1 is confirmed. The main technological factors influencing the carbon content in the entire technological chain of production in the NLMK’s CS-1 is determined.
