Dab tsi yog qhov txawv ntawm lub hwj chim zaus induction rauv thiab a medium zaus induction taws?

Ua ntej, lub hwj chim zaus induction rauv

Lub hwj chim zaus induction rauv yog lub qhov cub induction uas siv cov khoom siv tam sim no (50 lossis 60 Hz) ua lub zog. Lub hwj chim zaus induction rauv tau tsim rau hauv cov khoom siv smelting nrog ntau yam kev siv. Nws yog tsuas yog siv los ua lub qhov cub melting rau smelting grey cam khwb cia hlau, malleable cam khwb cia hlau, ductile hlau thiab alloy cam khwb cia hlau. Tsis tas li ntawd, nws kuj yog siv los ua lub qhov cub tuav. Raws li ua ntej, lub hwj chim zaus induction rauv tau hloov lub cupola ua cov khoom tseem ceeb rau casting ntau lawm. Piv nrog rau cupola, lub hwj chim zaus induction rauv muaj cov muaj pes tsawg leeg ntawm molten hlau thiab kub, thiab cov roj nyob rau hauv lub casting yog yooj yim los tswj. Muaj ntau yam zoo xws li kev suav nrog tsawg, tsis muaj kuab paug rau ib puag ncig, kev txuag hluav taws xob thiab txhim kho kev ua haujlwm. Yog li ntawd, nyob rau hauv xyoo tas los no, lub hwj chim zaus induction rauv tau tsim sai heev.

Lub zog zaus induction rauv ua tiav cov khoom siv suav nrog plaub ntu.

1. Rauv ib feem

Ib feem ntawm lub hwj chim zaus induction rauv ntawm smelting cam khwb cia hlau yog tsim los ntawm ib tug induction rauv (ob chav nyob, ib tug rau smelting thiab lwm yam rau standby), lub qhov cub cover, lub cub tawg thav duab, tilting lub tog raj kheej, thiab ib tug txav lub hau qhib thiab kaw ntaus ntawv.

2. Cov khoom siv hluav taws xob

Cov khoom siv hluav taws xob muaj xws li lub zog hloov hluav taws xob, lub ntsiab lus tseem ceeb, lub tshuab hluav taws xob sib npaug, lub ntsuas hluav taws xob sib npaug, cov nyiaj them poob haujlwm, thiab lub tshuab hluav taws xob.

3. Cua txias system

Cov dej txias txias muaj xws li capacitor txias, inductor txias, thiab mos cable txias. Lub tshuab dej txias yog tsim los ntawm lub twj tso kua mis, lub pas dej ua ke lossis lub tshuab ua kom txias, thiab lub raj xa dej.

4. Kev kaw lus hydraulic

Hydraulic systems muaj xws li roj tank, roj twj, roj twj tso kua mis motors, hydraulic system piping thiab li qub, thiab hydraulic consoles.

Qhov thib ob, qhov nruab nrab zaus induction rauv

Induction furnaces nrog nruab nrab zaus induction furnaces nrog lub zog zaus nyob rau hauv thaj tsam ntawm 150 txog 10,000 Hz yog hu ua intermediate zaus induction furnaces, thiab lawv lub ntsiab zaus yog nyob rau hauv thaj tsam ntawm 150 txog 2500 Hz. Hauv tsev me me zaus induction rauv fais fab mov zaus yog 150, 1000 thiab 2500 Hz.

Qhov nruab nrab zaus induction rauv yog cov cuab yeej tshwj xeeb tsim rau smelting zoo steel thiab alloy. Piv nrog rau lub hwj chim zaus induction rauv, nws muaj qhov zoo hauv qab no:

1) ceev melting ceev thiab siab ntau lawm efficiency. Lub zog ceev ntawm nruab nrab zaus induction rauv yog qhov loj, thiab lub zog teeb tsa ib tuj ntawm cov hlau molten yog li 20-30% loj dua li ntawm lub zog zaus induction rauv. Yog li ntawd, nyob rau hauv tib yam kev mob, qhov nruab nrab zaus induction rauv muaj lub siab melting ceev thiab siab ntau lawm efficiency.

2) Adaptability thiab saj zawg zog siv. Nyob rau hauv nruab nrab zaus induction rauv, cov hlau molten ntawm txhua lub cub tawg tuaj yeem ntxuav tag, thiab nws yooj yim los hloov cov hlau. Txawm li cas los xij, molten steel ntawm lub hwj chim zaus induction rauv tsis raug tso cai los ntxuav, thiab ib feem ntawm cov hlau molten yuav tsum tau tshwj tseg rau kev pib lub qhov cub. Yog li ntawd, nws tsis yooj yim los hloov cov hlau, tsuas yog siv tau. Smelting ib hom hlau.

3) Electromagnetic stirring nyhuv yog zoo dua. Txij li thaum electromagnetic quab yuam ntawm cov hlau molten yog inversely proportional rau lub square root ntawm lub hwj chim mov zaus, lub stirring zog ntawm lub nruab nrab zaus fais fab mov yog me dua li ntawm lub lag luam zaus fais fab mov. Rau kev tshem tawm ntawm impurities thiab cov tshuaj muaj pes tsawg leeg hauv cov hlau, qhov kub thiab txias, qhov sib xyaw ua haujlwm ntawm qhov nruab nrab zaus fais fab mov yog qhov zoo dua. Kev ntxhov siab ntau dhau ntawm cov khoom siv hluav taws xob ntau zaus ua rau lub zog ntws tawm ntawm cov hlau molten rau hauv ob sab phlu, uas tsis tsuas yog txo cov nyhuv refining tab sis kuj txo lub neej ntawm crucible.

4) Yooj yim pib thiab ua haujlwm. Txij li thaum cov nyhuv ntawm daim tawv nqaij ntawm qhov nruab nrab zaus tam sim no loj dua lub zog zaus tam sim no, qhov nruab nrab zaus induction rauv tsis muaj qhov tshwj xeeb rau tus nqi thaum pib, thiab tuaj yeem ua kom sov sai sai tom qab them nyiaj; thaum lub hwj chim zaus induction rauv yuav tsum tau tshwj xeeb ua qhib cov khoom thaiv. (Kwv yees li cov cam khwb cia hlau los yog cam khwb cia hlau thaiv, uas yog kwv yees li qhov loj ntawm lub crucible, uas yog hais txog ib nrab ntawm qhov siab ntawm lub crucible) tuaj yeem pib cua sov thiab cov cua sov yog qeeb heev. Yog li ntawd, qhov nruab nrab zaus induction rauv yog feem ntau siv nyob rau hauv cov xwm txheej ntawm lub sijhawm ua haujlwm. Lwm qhov zoo dua ntawm kev pib yooj yim yog tias nws txuag lub zog thaum lub voj voog ua haujlwm.

Vim qhov zoo li saum toj no, qhov nruab nrab zaus induction rauv tsis tau tsuas yog siv dav hauv kev tsim cov hlau thiab alloys nyob rau xyoo tas los no, tab sis kuj tseem nyob rau hauv kev tsim cov hlau cam khwb cia, tshwj xeeb tshaj yog nyob rau hauv kev cob qhia casting ntawm lub voj voog ua haujlwm.

Cov cuab yeej pabcuam rau nruab nrab zaus induction rauv

Qhov ua tiav ntawm qhov nruab nrab zaus induction rauv muaj xws li: lub hwj chim mov thiab hluav taws xob tswj qhov, qhov cub hluav taws xob, kev sib kis thiab dej txias.
