Nqus Induction Melting: Lub Tshuab Dub Rau Purifying Thiab Upgrading Hlau Khoom
Feb 28, 2026
Koj puas paub yuav ua li cas lub siab -kub- cov kav dej ntawm aero- cav thiab corrosion- cov kav dej tiv thaiv hauv cov chaw tsim hluav taws xob nuclear raug tsim? Qhov "pib taw tes" ntawm cov high - cov ntaub ntawv hlau kawg yog sib cais los ntawm cov cuab yeej tseem ceeb - Vacuum Induction Melting (VIM). Piv nrog rau cov txheej txheem melting ib txwm siv (xws li hluav taws xob arc rauv thiab nruab nrab-frequency furnaces), nws zoo li ua "precision purification + customized optimization" ntawm cov ntaub ntawv hlau, nrog rau qhov zoo.
Cias muab, lub hauv paus ntawm lub tshuab nqus tsev induction melting yog kev sib txuas ntawm "nqus ib puag ncig + hluav taws xob cua sov". Nws tuaj yeem tswj tau ntau yam khoom hauv cov hlau. Piv txwv li, thaum ntxiv cov ntsiab lus tseem ceeb niobium (Nb) rau npib tsib xee-raws li alloys, qhov kev ua yuam kev tuaj yeem tswj tau li ntawm 0.05%, thiab cov khoom tsis zoo xws li sulfur (S) thiab phosphorus (P) tuaj yeem txo qis dua 1/100,000, uas ua rau muaj kev purity ntau dua li ntawm.
Dab tsi zoo dua yog nws "kev tshem tawm impurity". Nyob rau hauv ib qho chaw siab -nqus tsev, "invisible killers" xws li hydrogen thiab oxygen hauv cov hlau raug tshem tawm tag nrho (piv txwv li, cov ntsiab lus hydrogen tuaj yeem qis li ib feem ntawm ib lab), zam qhov pores thiab tawg ntawm cov ntaub ntawv thaum ua tom ntej. Cov qis- melting- taw tes "cov teeb meem" (xws li cov hlau lead thiab tin) kuj evaporated, ua rau cov hlau ntxuav.
Ntxiv mus, tag nrho cov txheej txheem yog nqa tawm nyob rau hauv ib tug kaw lub tshuab nqus tsev vacuum, kiag li cais huab cua thiab sab nraud muaj kuab paug. Tsis zoo li ib txwm yaj, nws tiv thaiv cov hlau los ntawm reacting nrog oxygen thiab nitrogen nyob rau hauv cov huab cua los tsim impurities, kom ntseeg tau cov khoom zoo los ntawm qhov chaw. Nyob rau tib lub sij hawm, electromagnetic quab yuam ua zoo li ib tug "stirrer" kom uniformly tov cov hlau tov, tsis txhob muaj ib tug tsis sib xws. Los ntawm kev tswj cov cua txias, cov nplej hlau tau ua kom zoo rau qib micrometer, ua rau cov khoom siv tau yooj yim dua thiab nws cov kev ua tau zoo dua qub.
Nws yog cov peev txheej no uas ua rau lub tshuab nqus tsev induction melting "tus qauv" thev naus laus zis rau siab- cov ntaub ntawv hlau kawg (xws li npib tsib xee- cov alloys thiab titanium alloys), muab "cov khoom siv pob zeb" txhim khu kev qha rau cov khoom tseem ceeb hauv aerospace, nuclear zog thiab lwm yam.
