Research perspectives in the field of acoustic treatment of liquid alloys of iron

One of significant factors affecting properties of steel is uniform distribution of non metallic inclusions and alloy elements across the steel product cross-section. Acoustic treatment may be the final technological stage enabling the quality of steel to be influenced. Further research to be undertaken in this field should be focused on the design of power heads with application of a stack of several piezoceramic elements or what is referred to as a mosaic head, or consisting in simultaneous use of several heads. What is additionally required is to determine ranges of parameters of the acoustic treatment process for individual groups of steel grades.
