【Huate Magnetic Separation Encyclopedia】 Daim ntawv thov ntawm Electromagnetic Stirrer hauv Casting Kev Lag Luam

Kev sib xyaw ua ke ntawm cov hlau nplaum hluav taws xob tuaj yeem ua rau cov txhuas yaj tsis muaj kev sib cuag, ua kom cov tshuaj lom neeg sib xyaw thiab qhov kub ntawm cov yaj sib xyaw, txo qhov tsim ntawm oxide slag, luv lub sijhawm smelting, txhim kho kev tsim khoom, thiab txo qhov siv zog ntawm cov neeg ua haujlwm. Vim muaj ntau qhov zoo ntawm kev sib xyaw ua ke ntawm cov hlau nplaum hluav taws xob, cov hlau nplaum hluav taws xob tam sim no tau dhau los ua cov khoom siv tseem ceeb hauv kev lag luam yaj thiab casting txhuas.

Kev sib xyaw ua ke ntawm cov hlau nplaum hluav taws xob tuaj yeem ua rau cov txhuas yaj tsis muaj kev sib cuag, ua kom cov tshuaj lom neeg sib xyaw thiab qhov kub ntawm cov yaj sib xyaw, txo qhov tsim ntawm oxide slag, luv lub sijhawm smelting, txhim kho kev tsim khoom, thiab txo qhov siv zog ntawm cov neeg ua haujlwm. Vim muaj ntau qhov zoo ntawm kev sib xyaw ua ke ntawm cov hlau nplaum hluav taws xob, cov hlau nplaum hluav taws xob tam sim no tau dhau los ua cov khoom siv tseem ceeb hauv kev lag luam yaj thiab casting txhuas.

Lub tshuab hluav taws xob electromagnetic stirrer feem ntau yog tsim los ntawm lub zog hloov pauv zaus thiab lub inductor. Lub zog hloov pauv zaus hloov pauv 50/60Hz zog zaus hloov pauv mus rau hauv 3-theem qis zaus fais fab mov nrog zaus ntawm 0.5 ~ 5Hz. Tom qab lub zog muab hluav taws xob txuas nrog lub kauj inductor, yuav tsim lub zog sib nqus nthwv dej. Lub zog sib nqus nthwv dej mus ncig nkag mus rau hauv cov hlau tsis xeb phaj ntawm qab ntawm lub cub tawg thiab lub hauv paus ntawm lub cub tawg thiab ua haujlwm rau cov txhuas molten, yog li cov txhuas molten txav mus tas li, kom ua tiav lub hom phiaj ntawm kev sib xyaw. Qhov loj thiab kev coj ntawm lub zog sib xyaw tuaj yeem hloov pauv los ntawm kev hloov qhov hluav taws xob, zaus thiab theem ntawm lub zog hloov pauv zaus.

Qhov tseeb AC, DC, AC hloov pauv zaus fais fab mov nrog cov cai tswjfwm kev txawj ntse ywj pheej tsim los ntawm HuateLub Tuam Txhab thiab Nankai University, Shandong University thiab lwm lub tsev kawm qib siab thiab tsev kawm qib siab, muaj cov txee tswj hwm thiab lub txee fais fab zaus hloov pauv los tsim lub tshuab tsav electromagnetic stirrer.

Cov thev naus laus zis tswj PWM tshiab tshaj plaws tau rhuav tshem cov qauv sib koom ua ke ntawm lub converter zaus yav dhau los. Raws li cov yam ntxwv ntawm lub electromagnetic stirrer, kev tsim tshwj xeeb ntawm software thiab kho vajtse tau ua tiav. Nws tuaj yeem nqa lub nra hnyav inductive loj yam tsis ntxiv impedance matching ntawm lub zog fais fab thiab lub nra hnyav, thiab tuaj yeem ua haujlwm ntawm cov zaus qis. Kev ua haujlwm ruaj khov. Lub zog fais fab PWM hloov pauv zaus tshiab tshaj plaws yog qhov tsim nyog dua rau kev siv rau ntawm electromagnetic stirrers; piv nrog cov khoom siv fais fab zaus hloov pauv ib txwm muaj, lub zog fais fab PWM hloov pauv zaus tshiab tshaj plaws ntawm Huatemuaj cov yam ntxwv hauv qab no:

1. Lub zog fais fab: Lub zog fais fab ntawm qhov tseeb AC-DC-AC hloov pauv zaus fais fab mov tuaj yeem ncav cuag ntau dua 0.95, uas ua raws li lub teb chaws cov cai rau peb-theem fais fab circuits (0.9-1). 0.95 lossis li ntawd yog qhov zoo tshaj plaws. Yog tias lub zog fais fab siab dhau, qhov hluav taws xob yuav siab dhau. Piv nrog rau AC-AC qauv fais fab mov, lub peev xwm ntsia ntawm lub cuab yeej tuaj yeem txo qis heev.

2. Kev poob haujlwm tsis zoo: Sab rectifier ntawm qhov tseeb PWM AC-DC-AC hloov pauv zaus fais fab mov tsis xav tau lub voj voog tswj hwm nyuaj, cov khoom siv nws tus kheej muaj kev poob tsawg dua, thiab kev hloov pauv zoo dua li ntawm cov voj voog PWM ib txwm muaj. Thaum cov khoom siv nyob rau hauv lub xeev standby, cov khoom siv hluav taws xob hloov pauv zaus ib txwm muaj yuav tsum pauv lub zog loj nrog lub zog hluav taws xob grid kom tswj tau qhov ruaj khov ntawm DC tsheb npav voltage, thaum qhov tseeb PWM hloov pauv zaus fais fab mov yuav luag tsis muaj kev pauv zog nrog lub zog hluav taws xob grid. Hauv cov nqe lus ntawm qis dua li cov khoom siv hluav taws xob ib txwm muaj.

3. Kev poob haujlwm: Vim tias lub agitator yog lub nra hnyav inductive, tsis yog lub cev muaj zog, tsis muaj txheej txheem hloov pauv los ntawm lub zog kho tshuab mus rau lub zog hluav taws xob, yog li yuav luag tsis muaj kev tawm tswv yim zog thaum lub sijhawm ua haujlwm. Lub zog PWM tshiab paub txog kev sib pauv zog reactive nrog lub nra hnyav inductive los ntawm lub peev xwm loj DC capacitor, tsuas yog xav tau lub zog buffer, thiab tsis muaj kev hloov pauv zog, Yog li ntawd, lub zog PWM tshiab tshaj plaws muaj kev poob haujlwm qis dua li cov khoom siv hluav taws xob hloov pauv zaus ib txwm muaj.

4. Kev tawg hluav taws xob electromagnetic: Vim tias PWM hloov pauv zaus fais fab mov yog tsim los ntawm cov khoom siv hluav taws xob fais fab thiab modulated los ntawm cov zaus nqa khoom siab, cov khoom siv hluav taws xob hloov pauv zaus ib txwm muaj ob ntu: PWM rectifier thiab PWM inverter. Lub PWM rectifier ntsuas los ntawm lub zog hluav taws xob grid yuav tsim ntau tus lej ntawm cov harmonics siab thaum nws ua haujlwm. Txawm hais tias LC filtering siv rau sab grid, nws tseem ua rau muaj kev cuam tshuam hluav taws xob rau lub grid thiab cov khoom siv ib puag ncig; lub zog PWM tshiab tshaj plaws tsis muaj kev hloov pauv zaus siab ntawm sab grid, thiab Siv ntau theem LC filtering thiab transformer cais, qhov kev sim ua pov thawj tias kev cuam tshuam hluav taws xob ntawm sab grid yog me heev, thiab nws kuj kov yeej kev cuam tshuam ntawm lub ntiaj teb sab nraud ntawm lub zog hluav taws xob stirring.

5. Kev ruaj khov ntawm cov khoom siv: qhov tseeb PWM hloov pauv zaus fais fab mov, sab rectifier siv txoj kev tsis tswj hwm ntawm kev hloov pauv ntuj, tsis tas yuav muaj kev tswj hwm nyuaj, thiab lub voj voog yooj yim. Tsis tas li ntawd, vim yog kev siv ntau lub voj voog tiv thaiv, suav nrog kev tshawb pom kab nkag, DC capacitor nres chav tsev, kub dej, siab dej, thiab lwm yam, tshwj xeeb tshaj yog kev tiv thaiv ntau yam ntawm IGBT, ua rau lub kaw lus ua haujlwm txhim khu kev qha dua, thiab nws qhov xwm txheej siab heev, kev loj hlob thiab kev ruaj khov yog qhov pom tseeb dua.

Lub tshuab hluav taws xob electromagnetic stirrer uas Huate tsim muaj ntau dua 200 tus neeg siv khoom hauv tsev, thiab tau xa tawm mus rau ntau dua kaum lub tebchaws thiab thaj chaw xws li Brazil, Thaib thiab Is Nrias teb, thiab tau txais kev qhuas dav los ntawm cov neeg siv khoom.

Shandong Huate Magnetoelectric Technology Co., Ltd. tau tsim muaj xyoo 1993 (tus lej khoom lag luam: 831387). Lub tuam txhab yog tus yeej kev tsim khoom hauv tebchaws, lub tuam txhab tshwj xeeb, tshwj xeeb, thiab tshiab "me me loj" tseem ceeb hauv tebchaws, lub tuam txhab tsim kho tshiab hauv tebchaws, thiab lub tuam txhab tsim kho tshiab hauv tebchaws. Nws yog lub tuam txhab tseem ceeb high-tech, lub tuam txhab ua qauv qhia txog kev txawj ntse hauv tebchaws, lub tuam txhab ua lag luam hauv Linqu magnetoelectric khoom siv hauv paus ntawm National Torch Program, chav tswj hwm ntawm National Magnetoelectric thiab Low Temperature Superconducting Application Technology Innovation Strategic Alliance, thiab chav lwm thawj coj ntawm China Heavy Machinery Industry Association. . Muaj cov chaw ua haujlwm tshawb fawb tom qab kawm tiav qib siab hauv tebchaws, cov chaw ua haujlwm kawm tiav, cov chaw kuaj mob tseem ceeb hauv xeev rau cov cuab yeej siv magnetic thiab cov khoom siv, thiab cov chaw tsim khoom siv magnetic thiab hluav taws xob hauv xeev thiab lwm lub platform R&D.
