Ob yam yooj yim ntawm electromagnetic casting

Muaj ob yam yooj yim ntawm electromagnetic casting, ntsug thiab kab rov tav, thiab ntsug electromagnetic casting tuaj yeem muab faib ua rub-up thiab rub-down. Tam sim no, electromagnetic casting uas tau muab tso rau hauv kev lag luam ntau lawm nyob rau hauv lub ntiaj teb no yog tag nrho down-quoted. Yog li ntawd, phau ntawv no tsuas yog qhia txog cov khoom siv hluav taws xob hluav taws xob ntawm ntsug-draw aluminium thiab nws cov alloys.

8. 1. 2. 1 Cov khoom siv fais fab thiab nws qhov system

Cov cuab yeej siv hluav taws xob yog ib qho khoom siv tseem ceeb ntawm electromagnetic casting, nrog rau nruab nrab zaus generator teeb lossis thyristor nruab nrab zaus fais fab mov. Cov qub Soviet Union, Hungary, Czech koom pheej, lub teb chaws Yelemees thiab lwm lub teb chaws nyob sab Europe tau txais ib nrab zaus generator teev nyob rau hauv thaum ntxov ua sawv, thiab ib tug txheej ntawm generator teeb yuav tsuas cam khwb cia ib tug ingot. Tom qab xyoo 1970, cov teb chaws xws li Switzerland thiab Tebchaws Meskas tau siv thyristor nruab nrab zaus siv hluav taws xob rau electromagnetic casting technology, thiab cov khoom siv hluav taws xob tuaj yeem nrum ntau yam khoom siv. Lub thyristor nruab nrab zaus fais fab mov muaj ntau yam zoo dua li nruab nrab zaus generator teeb, yog li nws yog dav siv.

Lub hauv paus ntsiab lus ntawm electromagnetic casting fais fab system yog qhia nyob rau hauv daim duab 8-6.

Daim duab 8-6 Schematic daim duab ntawm lub hwj huam mov system

1-square aluminium ingot; 2-pwm induction kauj; 3-intermediate zaus transformer; 4-kev them nyiaj yug capacitor;

5-Inverter Circuit Court; 6-Smoothing inductor; 7-Rectification Circuit Court; 8- Peb-theem AC tam sim no

Lub thyristor intermediate zaus fais fab mov yog ib qho khoom siv uas hloov peb-theem fais fab zaus hloov tam sim no rau hauv nruab nrab zaus hloov tam sim no. Nws siv AC-DC-AC zaus hloov dua siab tshiab Circuit Court, uas yog tus cwj pwm los ntawm kev sib txuas nruab nrab. Los ntawm lub rectifier Circuit Court, lub zog zaus AC lub zog yog thawj zaug hloov mus rau DC lub zog, thiab tom qab ntawd lub zog DC hloov dua siab tshiab rau hauv AC lub zog nrog lub zaus ntawm / los ntawm lub inverter Circuit Court. Lub thyristor nruab nrab zaus fais fab mov muaj qhov zoo ntawm qhov yooj yim Circuit Court, yooj yim debugging, txhim khu kev qha lag luam, thiab efficiency siab tshaj 90%. Cov khoom siv uas muaj peev xwm sib txawv muaj qhov sib txawv me ntsis tswj lub voj voog thiab cov qauv sib txawv, tab sis lub hauv paus ntsiab lus yog tib yam.
