Yuav ua li cas xam cov melting tus nqi thiab productivity ntawm induction melting rauv?

Nws yuav tsum tau taw qhia tias cov ntaub ntawv muaj peev xwm melting ntawm cov hluav taws xob hluav taws xob muab los ntawm cov dav dav induction melting rauv chaw tsim tshuaj paus nyob rau hauv cov qauv los yog technical specification yog tus nqi melting. Lub melting tus nqi ntawm lub cub hluav taws xob yog cov yam ntxwv ntawm lub cub hluav taws xob nws tus kheej, nws muaj feem xyuam rau lub hwj chim ntawm lub cub tawg hluav taws xob thiab hom hluav taws xob qhov hluav taws xob, thiab tsis muaj dab tsi cuam tshuam rau kev ua haujlwm ntawm kev tsim khoom. Kev tsim khoom ntawm lub cub hluav taws xob tsis yog tsuas yog cuam tshuam nrog kev ua haujlwm melting ntawm lub cub hluav taws xob nws tus kheej, tab sis kuj tseem cuam tshuam nrog kev ua haujlwm melting. Feem ntau, muaj qee yam tsis muaj lub sijhawm thauj khoom hauv lub voj voog ua haujlwm melting, xws li: pub mis, skimming, sampling thiab kuaj, tos rau cov txiaj ntsig kev xeem (txog qhov kev xeem txhais tau tias), tos rau pouring, thiab lwm yam. Lub neej ntawm Lub sijhawm tsis muaj kev thauj khoom no txo ​​qis lub zog ntawm cov khoom siv hluav taws xob, uas yog, txo cov peev txheej ntawm lub tshuab hluav taws xob.

Txhawm rau kom meej meej ntawm cov lus piav qhia, peb qhia cov ntsiab lus ntawm lub tshuab hluav taws xob hluav taws xob hluav taws xob siv hluav taws xob K1 thiab kev siv hluav taws xob siv hluav taws xob ua haujlwm K2.

Lub tshuab hluav taws xob hluav taws xob hluav taws xob siv hluav taws xob K1 yog hais txog qhov sib piv ntawm cov khoom siv hluav taws xob ntawm cov khoom siv hluav taws xob rau nws lub zog ntsuas thaum lub sij hawm tag nrho melting voj voog, thiab nws muaj feem xyuam rau hom fais fab mov. Tus nqi K1 ntawm qhov nruab nrab zaus induction rauv nruab nrog silicon tswj (SCR) tag nrho-bridge parallel inverter khoom fais fab mov feem ntau yog nyob ib ncig ntawm 0.8. Xi’an lub koom haum ntawm Mechanical thiab Hluav Taws Xob Technology tau ntxiv inverter tswj rau hom fais fab mov no (feem ntau hom fais fab no tsuas muaj rectifier tswj), tus nqi yuav nyob ze rau 0.9 los yog li ntawd. Tus nqi K1 ntawm qhov nruab nrab zaus induction rauv nruab nrog (IGBT) lossis (SCR) ib nrab-bridge series inverter fais fab sib koom cov khoom siv fais fab tuaj yeem ncav cuag 1.0.

Qhov loj ntawm kev siv hluav taws xob siv hluav taws xob coefficient K2 muaj feem cuam tshuam nrog rau cov khoom xws li cov txheej txheem tsim thiab kev tswj hwm qib ntawm lub tshuab ua haujlwm melting, thiab cov txheej txheem kev teeb tsa ntawm lub tshuab hluav taws xob hluav taws xob. Nws tus nqi yog sib npaug rau qhov sib piv ntawm cov khoom siv hluav taws xob tiag tiag ntawm cov khoom siv hluav taws xob rau lub zog tso zis hluav taws xob thaum lub sijhawm ua haujlwm tag nrho. Feem ntau, kev siv hluav taws xob coefficient K2 raug xaiv ntawm 0.7 thiab 0.85. Lub sijhawm luv luv ntawm lub sijhawm tsis muaj lub tshuab hluav taws xob ua haujlwm ntawm lub cub hluav taws xob (xws li: pub mis, kuaj, tos rau kev sim, tos rau nchuav, thiab lwm yam), qhov loj dua K2 tus nqi. Siv Table 4 Scheme 4 (dual power supply with two furnace system), K2 value theoretically ncav cuag 1.0, qhov tseeb, nws muaj peev xwm ncav cuag ntau tshaj 0.9 thaum lub sij hawm tsis muaj-load auxiliary ua hauj lwm ntawm lub cub hluav taws xob tsawg heev.

Yog li ntawd, qhov tsim tau N ntawm lub cub hluav taws xob tuaj yeem xam los ntawm cov qauv hauv qab no:

N = P·K1·K2 / p (t/h) ………………………………………………………………… (1)

Qhov twg:

P – ntsuas lub zog ntawm lub qhov cub hluav taws xob (kW)

K1 – Lub tshuab hluav taws xob hluav taws xob siv hluav taws xob, feem ntau nyob hauv thaj tsam ntawm 0.8 ~ 0.95

K2 – Kev siv hluav taws xob ua haujlwm, 0.7 ~ 0.85

p – hluav taws xob rauv melting unit noj (kWh / t)

Siv 10t intermediate zaus induction melting rauv nruab nrog 2500kW silicon tswj (SCR) tag nrho-bridge parallel inverter khoom siv hluav taws xob tsim los ntawm Lub Tsev Haujlwm ntawm Mechanical thiab Hluav Taws Xob Engineering ua piv txwv. Chav tsev melting noj p qhia nyob rau hauv cov kev specifications yog 520 kWh / t, thiab lub cub hluav taws xob siv hluav taws xob qhov tseem ceeb Tus nqi ntawm K1 yuav ncav cuag 0.9, thiab tus nqi ntawm kev khiav hauj lwm hwj chim siv yam K2 yog npaum li cas 0.85. Kev tsim khoom ntawm lub tshuab hluav taws xob tuaj yeem tau txais raws li:

N = P·K1·K2 / p = 2500·0.9·0.85 / 520 = 3.68 (t / h)

Nws yuav tsum tau taw qhia tias qee cov neeg siv tsis meej pem lub ntsiab lus ntawm melting tus nqi thiab cov khoom tsim tau, thiab suav tias yog tib lub ntsiab lus. Lawv tsis xav txog qhov hluav taws xob hluav taws xob hluav taws xob siv hluav taws xob coefficient K1 thiab kev siv hluav taws xob siv hluav taws xob ua haujlwm K2. Qhov tshwm sim ntawm qhov kev suav no yuav yog N = 2500/520 = 4.8 (t / h). Lub cub hluav taws xob xaiv nyob rau hauv txoj kev no tsis tuaj yeem ua tiav cov khoom tsim tau.
