Description

6 импульсных токон. Внутри полости 4 между электродами 5 и наружной стенкой стакана 1 происходит високовольтный импульсный разр д. За счет высокого давлени  по стакану 1 проходит ударна  волна, котора  разрушает намерзающую на внутреннюю стенку стакана 1 корочку металла , осколки которого унос тс  струей жидкого металла в литейную форму 8. В послеразр дный период за счет пульсации парогазовой полости, в рабочей жидкости возникают возмущени , вызывающие осевые упругие колебани  стенок 2 и стакана 1 , которые способствуют дегазации и перемешиванию расплава. В результате виброимпульсной обработк жидкого металла в струе наблюдаетс  измельчение структуры литого металла в литейной форме 8 и ускорение процесса формировани  отливки.6 pulse tokons. Inside the cavity 4 between the electrodes 5 and the outer wall of the glass 1, a high-voltage pulsed discharge occurs. Due to the high pressure, a shock wave passes through the glass 1, which destroys the crust of metal 1 that freezes the inner wall of the glass, the fragments of which are carried by the jet of liquid metal into the mold 8 In the post-discharge period, due to the pulsation of the vapor-gas cavity, disturbances arise in the working fluid, causing axial elastic oscillations of the walls 2 and glass 1, which contribute to the degassing and mixing of the melt. As a result of the vibro-impulse treatment of the liquid metal in the jet, the grinding of the structure of the cast metal in the casting mold 8 and the acceleration of the casting process are observed.
