Metallurgical Metal Solution Degassing Ultrasonic Technology

Ultrasonic hlau yaj khoom siv tsuas yog siv nyob rau hauv metallurgical kev lag luam, nyob rau hauv lub ultrasonic vibration tej yam kev mob, cov hlau tov yog conducive rau degassing, de-impurities, refining lub grain, thiab ntxiv dag zog rau cov txheej txheem leaching, thiab lwm yam. Ultrasonic hlau yaj cov khoom siv rau lub molten. hlau tov tuaj yeem ua tiav qhov sib xyaw ntawm fibers thiab hlau hauv lub sijhawm luv luv, thiab cov ntaub ntawv sib xyaw ua haujlwm siab tau npaj. Cov hlau ua kua tuaj yeem nkag mus rau hauv cov particle preform lossis sib tov sib npaug nrog cov khoom raws li kev txiav txim ntawm ultrasound, thiab ultrasonic dip plating tuaj yeem paub steel hlau galvanization thiab txhuas plating.

Ultrasonic hlau yaj kho cov cuab yeej siv cov nyhuv cavitation ntawm ultrasonic tsis nyob rau hauv lub yaj, uas yuav txiav thiab puas dendrites, cuam tshuam lub solidification pem hauv ntej, nce stirring diffusion, homogenize tus qauv, thiab ua rau kom lub zog tensile ntawm cov ntaub ntawv hlau, txhim kho hlau toughness. Cov nplej loj yog me me thiab thaj tsam ntawm thaj tsam loj, uas tuaj yeem tiv thaiv kev tsis sib haum xeeb thiab kev sib txuam sib luag, txhais tau hais tias yuav tsum muaj zog ntau dua kom tawg cov khoom. Lub finer lub grain loj, qhov me dua qhov dendrite qhov sib txawv, qhov siab dua lub zog tawm los, thiab qhov zoo dua qhov hardness. Qhov zoo tshaj plaws ingot qauv yog ib tug niaj hnub thiab me me equiaxed siv lead ua nyob rau hauv tag nrho cov ntoo khaub lig-section ntawm lub ingot, nrog tsawg anisotropy ntawm equiaxed muaju. Nws muaj qhov sib txawv deformation, kev ua tau zoo heev, thiab cov yas zoo thaum ua tiav, uas yog qhov zoo rau kev ua cov yas thiab cov yas tom qab. Txoj hauv kev zoo tshaj plaws kom tau txais cov koom haum no tam sim no yog siv cov khoom siv ultrasonic hlau yaj los kho cov hlau molten los ntawm kev kho ultrasonic.

Thaum tsim cov castings los ntawm kev kho ultrasonic kev co, ultrasonic tsis tsim alternating zoo thiab tsis zoo suab siab thaum propagation, tsim ib tug dav hlau. Nyob rau tib lub sijhawm, vim tsis muaj cov teebmeem, lub suab thiab micro suab ntws tau tsim, thiab ultrasonic cavitation generates high-speed micro jets ntawm cov khoom-kua interface. Cov nyhuv cavitation hauv cov kua ultrasonic tuaj yeem txiav tawm thiab rhuav tshem cov dendrites, cuam tshuam rau pem hauv ntej solidification, nce stirring thiab diffusion, thiab ua tiav cov teebmeem ntawm purifying ntaub so ntswg, refining nplej, thiab homogenizing ntaub so ntswg. Ntxiv nrog rau cov nyhuv ntawm kev puas tsuaj dendrites tshwm sim los ntawm kev vibration, lwm lub luag haujlwm tseem ceeb ntawm ultrasonic kev co solidification yog kom ua tau zoo undercooling ntawm cov hlau molten, txo qhov tseem ceeb nucleation radius, yog li nce tus nqi nucleation thiab refining cov nplej.
