Yuav ua li cas nrog cov rwb thaiv tsev ntawm induction melting rauv coils?

1. Rau 380V cov kab hluav taws xob nkag, qhov hluav taws xob ntawm ob qho kawg ntawm lub kauj yog 750V, thiab qhov hluav taws xob ntawm qhov hloov pauv kuj yog ob peb kaum ntawm volts. Yog hais tias qhov kev ncua deb ntawm lem yog loj txaus, qhov kev ncua deb ntawm lem kuj yuav siv tau raws li rwb thaiv tsev. Qhov no yog kev kho thaum ntxov. Yog hais tias cov hlau slag splashes ntawm lub kauj, ib tug luv luv Circuit Court ntawm lem yuav raug tsim, thiab tam sim no txoj kev no tau raug tshem tawm.

2. Cov txheej txheem kev kho hluav taws xob feem ntau siv rau induction melting furnace coils yog plaub txoj kev kho cua sov. Ua ntej, tshuaj tsuag insulating xim rau saum npoo ntawm lub kauj; thib ob, qhwv ib txheej ntawm mica daim kab xev rau ntawm lub kauj uas tau muab txau nrog cov xim insulating; thib peb, qhwv ib txheej ntawm iav ribbon rau sab nraud ntawm daim kab xev mica; Thaum kawg, tsuag ib txheej ntawm insulating xim. Xws li cov txheej txheem rwb thaiv tsev tuaj yeem ua kom ntseeg tau tias cov rwb thaiv tsev tiv taus qhov hluav taws xob ntawm induction melting rauv kauj yog siab li 5000V.

3. Lwm txoj kev ntawm rwb thaiv tsev kho mob rau induction melting rauv coils yog mus ncaj qha tshuaj tsuag high-temperature insulating xim. Qee cov xim insulating feem ntau thov tias qhov kub tuaj yeem tiv taus 1800 ° C, tab sis txau cov xim kub-kub insulating kuj yog ib txoj hauv kev yooj yim. Kev hais lus theoretical, qhov siab dua qhov rwb thaiv tsev ntawm cov xim kub-kub insulating, qhov siab dua qhov kub tsis kam ntawm cov xim insulating. Lub siab ntim resistivity ntawm high-temperature insulating xim yog ntau dua 1016Ωm ntawm chav tsev kub. Lub zog dielectric siab (lub zog tawg), ntau dua 30KV / m. Nws muaj cov tshuaj lom neeg ruaj khov zoo, kev laus ua haujlwm, tiv thaiv corrosion thiab zoo soothing reactivity. Tsis muaj flash point, tsis muaj ignition point, siab hardness, hardness ntau dua 7H. Thaum tshav kub kub tsis kam 1800 ℃, tuaj yeem ua haujlwm hauv qab nplaim taws ntev.

4. Txawm hais tias lub rwb thaiv tsev ntawm lub induction melting furnace coil yog cov rwb thaiv tsev ntawm qhov sib nrug deb, los yog winding ntawm insulating cov ntaub ntawv los yog cov tshuaj tsuag ntawm high-temperature insulating xim, ib txheej ntawm refractory kua nplaum yuav tsum tau siv nyob rau hauv lub coil thiab nruab nrab. cov lem ntawm lub kauj.

Coil refractory mortar yog siv rau coil ntawm induction melting rauv. Nws yog sib npaug ntawm nws qhov chaw thiab qhov ramp, uas muaj cov nyhuv insulating zoo, thiab tuaj yeem tiv thaiv qhov luv luv los yog tawm ntawm cov coils los ntawm kev tsim hluav taws xob ntau dhau los txhawm rau hlawv cov thyristor. Lub kauj yog aging thiab lub kauj yog ignited vim dej to, uas muaj peev xwm zoo tiv thaiv lub cub tawg los ntawm lub cub tawg vim qhov kub ntawm cov hlau molten.
