FIELD: metallurgy. ^ SUBSTANCE: device for supply of purging gases and simultaneous generation of ultrasonic vibrations into liquid metal of Hartman radiator type consists of case and of tube connected with case for supply of pulsing flow of gas. Coaxial and travelling one relative to another a nozzle and a resonator are installed in the case. An electrically insulated soldered joint of a thermo-pair is set in the case of the resonator. Another soldered joint of the thermo-couple is located in a cold zone beyond the radiator. Also, the first soldered joint of the thermo-couple is cooled at current transmission, simultaneously cooling a bottom of the resonator heated with compression shocks, while another soldered joint of the thermo-couple is heated and transmits heat into environment. ^ EFFECT: increased service life, thermo- and wear resistance of bottom of resonator, stabilised operation and increased resource of device for supply of purging gases and simultaneous generation of ultrasonic vibrations into liquid metal under conditions in intensive heating. ^ 1 dwg |
