Description
(54) СПОСОБ ЗАКАЛКИ МЕТАЛЛИЧЕСКИХ ИЗДЕЛИЙ(54) METHOD FOR HARDENING METAL PRODUCTS
де. .4агнитост:1 кционные преобразователи соединены с ге оратором ультразвуковых колебаний , который работает на частоте 22 кГц. В процессе охлаждени колец в масле избыточное давление над зеркалом жидкости в ванне плавное снижали до атмосферного. Выдел ющиес при этом в масле воздушные (газовые) пузырьки, вл ющиес зародыщами кавитации, обеспечивали интенсификацию процесса закалки.de. .4 magnetostatics: 1 part transducers are connected to an ultrasonic oscillation heaver that operates at a frequency of 22 kHz. In the process of cooling the rings in the oil, the excess pressure above the mirror of the fluid in the bath was gradually reduced to atmospheric. The air (gas) bubbles released in the oil, which are cavitation germs, intensified the hardening process.
Использование предлагаемого способа закалки обеспечивает по сравнению с существующими способами следующие преимущества: упрощение технологического оборудовани , снижение его металлоемкости; снижение времени охлаждени ; снижение энергии ультразвуковых колебаний, необходимой дл образовани кавитации.The use of the proposed method of quenching provides in comparison with existing methods the following advantages: simplification of the process equipment, reduction of its metal intensity; reduced cooling time; reducing the energy of ultrasonic vibrations necessary for the formation of cavitation.
Формула (Гни Formula (Rot
Способ закалк -: л;еал„1ических изделий , включаюпщй нагрев и охлаждение в жидкой среде под избыточным давлением с одновременным наложением на жидкость ультразвуковых колебаний, отличающийс тем, что, с целью интенсификации закалки, избыточное давление снижают до атмосферного .Quenching method -: l; eal; 1 products, including heating and cooling in a liquid medium under excess pressure with simultaneous imposition of ultrasonic vibrations on the liquid, characterized in that, in order to intensify the hardening, the excess pressure is reduced to atmospheric.
