The work principle and technology characteristics of developed technology of vibration-excited nucleation in liquid and the treated effect on ingot of metal zinc ingot and 1Cr17 ferrite stainless steel ingot in lab are presented. And the commercial pilot production for application of developed device using the technology of vibration-excited nucleation in liquid for 220 mm x 1 600 mm slab caster on 16Mn series steel grades is carried out. Application results show that for the cast slab non-treated by vibration-excited nucleation the equiaxed zone rate of slab is ≤ 10% with center porosity and segregation rating 1.5
but for the cast slab treated by vibration-excited nucleation the equiaxed zone rate of slab is ≥ 30% with center porosity and segregation rating 0. 5. Analysis shows that for large-scale ingot
application of technology of vibration-excited nucleation in liquid is available to control solidification structure of ingot in line
increase equiaxed zone rate of ingot and improve its inner quality.
