| Abstract Scope |
The article considers the opportunities of using ultrasonic treatment to create conditions conducive to modify of the structure, as well as conditions that reduce the consumption of the supplied modifying rod for large-sized slabs of 5083 alloy manufactured by DC casting. Established the effective power range of ultrasonic waves for influencing the melt and the effective flow rate of the modifying rod supplied together with the use of ultrasound.
The reduction in modifier consumption is due to the effect of advanced cavitation on TiB2 agglomerates, as well as “activation”, i.e., wetting of potential nucleating particles, thereby creating more crystallization centers.
It is shown that the use of ultrasonic treatment promote to the removal of dissolved gases from the melt in industrial production. The removal of gases, similar to the modifying of the structure, is promoted by cavitation, forming microzones of different partial pressure, grabbing the gases dissolved in the melt. |
