The article discusses the problem of the formation of magnesia spinel (MgO·al₂o₃) in steelmaking processes, affecting the quality of steel, especially in the production of electro-welded pipes. The mechanisms of spinel formation are described, including the interaction of refractories with melt and slag, as well as the main chemical reactions contributing to the formation of nonmetallic inclusions. The analysis of technological factors affecting the MgO content in bucket slag is carried out, and methods for its stabilization are proposed. Technological measures have been developed and implemented to minimize the formation of inclusions: temperature control of the bucket lining, correction of the slag composition, digital monitoring of the bucket condition, optimization of argon purging and stricter requirements for slag-forming materials. Analysis of data for 2014-2017 showed a decrease in the MgO content in bucket slag and a decrease in defects in finished products. The implementation of the proposed measures made it possible to stabilize the chemical composition of the slag, reduce the level of non-metallic inclusions and improve the quality of steel, which is confirmed by a reduction in the number of defects in pipe welds. The developed recommendations can be used to optimize steelmaking processes and increase the competitiveness of metallurgical products.
