Dab tsi yog qhov cuam tshuam ntawm flange hom hluav taws xob cua sov raj cua sov ntawm cov cim vuam

Dab tsi yog qhov cuam tshuam ntawm kev nyab xeeb ntawm kev siv flange hom cua sov ntawm cov cim vuam? Thaum siv lub flange hom cua sov kom muaj kev nyab xeeb rau cua sov, tus cwj pwm ntws hauv qhov chaw yaj hauv pem hauv ntej yog qhov nyuaj heev, thiab nws txoj kev ntws zoo li tus ciav dej, ntws tawm ntawm qhov nruab nrab ntawm cov kua dej pem hauv ntej thiab ntws mus rau ntawm phab ntsa ntawm cov pwm kab noj hniav.
Hauv qhov xwm txheej no, thaum ob lub taub dej sib ntsib, cov kua dej ntawm qhov chaw ua ntej sib cuag, tsim ib qho chaw fusion, uas tom qab ntawd txhim kho radially los ntawm qhov chaw mus rau phab ntsa pwm, thaum kawg tsim ib cheeb tsam fusion. Yog li ntawd, fusion cov cim yog cov ciam teb tsim los ntawm fusion ntawm ob los yog ntau dua yaj ntws pem hauv ntej nyob rau hauv pwm kab noj hniav, thiab nyias-walling ntawm yas qhov chaw tsub kom lub filling tsis kam thaum molding. Nyob rau hauv xyoo tas los no, flange hom heaters tau dav siv nyob rau hauv industrial ntau lawm rau kub forging, xws li iav thiab ncej quenching. Lub flange hom rhaub yog ib hom rhaub uas hloov peb-theem AC lub zog rau hauv DC lub zog tom qab kev kho, thiab tom qab ntawd hloov DC lub zog rau hauv qhov hloov tau tam sim no los muab cov AC tam sim no ntws los ntawm lub capacitor thiab electromagnetic induction coil. Nws generates high-density magnetic kab nyob rau hauv lub electromagnetic coil thiab txiav cov hlau composite cov ntaub ntawv uas muaj nyob rau hauv lub electromagnetic coil, generating loj eddy tam sim no nyob rau hauv cov hlau composite khoom. Hom eddy tam sim no kuj muaj qee yam khoom ntawm qhov nruab nrab zaus tam sim no, uas yog, cov hluav taws xob dawb ntawm cov hlau nws tus kheej ntws hauv lub cev hlau resistive los ua kom sov. Nrog rau kev txhim kho ntawm kev tswj cov tshuab hluav taws xob thiab cov khoom siv hluav taws xob semiconductor, cov khoom siv hluav taws xob hauv lub xeev flange rhaub tau ua tiav sai. Txij li thaum xyoo 1950, ib lub tuam txhab Asmeskas tau tsim lub ntiaj teb thawj cov khoom lag luam thyristor, khoom siv hluav taws xob flange rhaub fais fab tshuab tau txais kev mloog zoo thiab kev tshawb fawb tob tob thoob ntiaj teb. Nws tshwm sim tau coj ib tug tshiab kiv puag ncig rau high-frequency induction cua sov tshuab thiab tag nrho cov fais fab electronics teb. Nrog rau kev tshawb fawb tob zuj zus thiab kev xav tau ntawm daim ntawv thov, high-frequency induction cua sov tshuab thiab flange rhaub fais fab mov yuav raug tsim thiab dav siv. Nyob rau hauv lub high-frequency (tshaj 100kHz) ntau yam, txawv teb chaws lub teb chaws tau hloov mus rau transistor raws li tag nrho cov khoom siv hluav taws xob hauv lub xeev feem ntau suav nrog cov khoom siv hluav taws xob thiab muaj peev xwm MOSFET. Xyoo 1989, Lub teb chaws Yelemees tau tsim cov khoom siv tam sim no MOSFET induction cua sov nrog lub peev xwm ntawm 480kW / 50-200kHz; Spain kuj tau tsim hom tam sim no MOSFET flange rhaub fais fab mov nrog lub peev xwm ntawm 600kW / 400kHz, thaum Yingda Tuam Txhab hauv Tebchaws Meskas kuj tau tsim lub 2000Kw / 400KHz MOSFET flange rhaub. Daim ntawv thov ntawm nto quenching rau flange heaters:
Piv nrog rau cov cua sov zoo tib yam quenching, nws muaj:
1. Cov cua kub ceev ceev ceev heev, uas tuaj yeem nthuav dav qhov kub thiab txias ntawm A-lub cev hloov pauv thiab txo lub sijhawm hloov pauv. 2. Tom qab quenching, nto ntawm lub workpiece tuaj yeem tau txais zoo heev cryptocrystalline martensite nrog me ntsis hardness (2 ~ 3HRC). Tsawg brittleness thiab siab qaug zog lub zog. 3. Cov workpieces ua tiav los ntawm cov txheej txheem no tsis yooj yim oxidized thiab decarburized, thiab txawm tias qee qhov workpieces tuaj yeem sib sau ncaj qha thiab siv yam xyuam xim tom qab kho. 4. Lub quenching txheej yog qhov sib sib zog nqus, yooj yim rau kev tswj thiab ua haujlwm, thiab yooj yim rau kev ua tiav tshuab thiab automation.
