Qhia koj yuav ua li cas khiav lub induction melting rauv

Pib txheej txheem ntawm induction melting rauv:

Ua ntej pib, xyuas seb qhov hluav taws xob hluav taws xob puas zoo, seb cov khoom puas puas lawm, seb txhua qhov chaw sib txuas puas yog xoob lossis raug txiav.

Phenomenon, yog tias qhov teeb meem saum toj no tshwm sim, lub hwj huam mov tuaj yeem tig rau tom qab qhov kev ua txhaum raug tshem tawm.

(1) Hu rau cov neeg ua haujlwm substation ntawm lub luag haujlwm kom kaw qhov hloov pauv ntawm lub qhov cub induction melting rauv, lub zog ntawm lub qhov cub induction melting, thiab kos npe rau cov ntaub ntawv xa hluav taws xob;

(2) Hnav cov hnab looj tes thiab kaw rau XNUMX phau ntawv hloov pauv nyob rau hauv lub hwj chim faib txee, thiab saib seb cov voltmeter tuaj ntawm lub vaj huam sib luag puas yog cov khoom siv hluav taws xob, thiab peb-theem cov khoom siv hluav taws xob yuav tsum sib npaug;

(3) Pib cov kab voltmeter nkag mus rau ntawm lub hwj huam mov txee los tso saib lub hwj chim mov voltage, lub hwj chim-on taw qhia teeb (daj) yog nyob rau, thiab lub inverter lub hwj chim teeb liab teeb liab (liab) yog nyob rau, thawj tig lub hwj chim potentiometer counterclockwise. mus rau xoom txoj hauj lwm (mus txog rau thaum kawg), thiab nias lub inverter Lub khawm ua hauj lwm (ntsuab), lub inverter ua hauj lwm qhia lub teeb (ntsuab) yog nyob rau, thiab lub pointer ntawm lub DC voltmeter ntawm lub qhov rooj vaj huam sib luag yuav tsum nyob rau hauv lub zero scale;

(4) Litre zog. Ua ntej, kho lub hwj chim potentiometer clockwise me ntsis. Nyob rau lub sijhawm no, xyuam xim rau kev tsim cov zaus nruab nrab thiab hnov ​​lub suab ntxhi, qhia tias qhov nruab nrab zaus fais fab mov tau pib ua tiav. Tsuas yog tom qab ntawd tuaj yeem tso cai rau lub hwj chim potentiometer tig maj mam nyob rau hauv lub clockwise kev taw qhia, thiab tsis rub nws sai. Lub hwj chim, nce lub zog maj mam, yog tias qhov IF zaus tseem tsis tsim, tig lub potentiometer rov qab thiab rov pib dua;

(5) Thaum lub hwj chim qhib, yog tias tsis muaj lub suab txawv txav ntawm qhov nruab nrab zaus zaus, nws yuav tsum tsis txhob yuam kom pib, ces lub potentiometer yuav tsum tau thim rov qab counterclockwise mus rau qhov kawg, thiab rov pib dua. Yog tias ob peb zaug ua tsis tiav, nws yuav tsum raug kaw thiab kuaj xyuas;

(6) Thaum pib ntawm kev thauj khoom (thaum tsis tu ncua loading steel ingots), lub hwj chim yuav tsum tau hloov mus rau 2000kW, yog li ntawd lub hwj chim hloov potentiometer yuav tsum muaj ib tug margin (lub potentiometer yuav tsum tsis txhob hloov mus rau tag nrho) kom tiv thaiv tau sai li sai tau nce nyob rau hauv potentiometer. lub zog thiab tam sim no vim yog cov txheej txheem thauj khoom siab, ua rau muaj kev puas tsuaj rau thyristor. Tom qab kev thauj khoom tiav, maj mam nce lub zog kom ntau dua 3000kW;

(7) Nyob rau hauv nruab nrab thiab lig theem ntawm smelting, lub hwj chim yuav tsum tau txo mus rau 2000kW (txo lub zog). Tom qab ua tiav tiav, maj mam kho lub zog kom ntau dua 3000kW kom tiv thaiv kom tsis txhob muaj zog thiab tam sim no thaum lub sijhawm them nyiaj. Kev puas tsuaj ntawm thyristor;

(8) Yog tias muaj cov khoom tsim tawm hauv lub qhov cub, tsis txhob kho lub hwj chim potentiometer tam sim no, thiab tsis txhob ua haujlwm ntawm lub zog siab. Lub hwj chim yuav tsum tau tswj ntawm 2000kW los tiv thaiv cov hlau ingots los ntawm kev poob rau hauv lub cub tawg dheev, ua rau muaj zog thiab tam sim no. , ua rau muaj kev puas tsuaj rau lub thyristor;

(9) Thaum lub sij hawm smelting txheej txheem, yog tias lub kaw lus dheev tawm mus, koj yuav tsum ua tib zoo txheeb xyuas qhov ua rau ntawm kev mus txawv tebchaws, thiab ua tib zoo xyuas lub hwj chim txee thiab qhov nruab nrab zaus lub zog hluav taws xob rau cov xau, lub siab ib txwm, thiab cov cim ntawm qhov hluav taws xob. Tsis txhob rov pib dua qhov nruab nrab zaus fais fab mov dig muag. , txhawm rau tiv thaiv kev nthuav dav ntawm qhov txhaum, ua rau muaj kev puas tsuaj rau lub zog hluav taws xob, thyristor thiab lub rooj tsav xwm loj;

(10) Qhov kev sib raug zoo ntawm qhov tam sim no thiab qhov hluav taws xob thaum lub hwj chim hloov mus rau tag nrho lub hwj chim potentiometer yog:

IF voltage = DC voltage x 1.3

DC voltage = nkag voltage x 1.3

DC tam sim no = cov kab nkag tam sim no x 1.2

(11) Tom qab paub meej tias txhua yam zoo li qub tom qab kaw, dai lub cim (lub zog xa hluav taws xob) rau ntawm phau ntawv nres.

Induction melting rauv shutdown standard

(1) Ua ntej tig lub hwj chim potentiometer counterclockwise mus rau qhov kawg. Thaum lub DC ammeter, DC voltmeter, zaus ntsuas, nruab nrab zaus voltmeter, thiab lub hwj chim ntsuas ntawm lub inverter fais fab txee yog tag nrho xoom, nias lub inverter nres khawm (liab), Lub inverter nres qhov taw qhia teeb (liab) yog nyob rau.

(2) Rub lub XNUMX phau ntawv hloov pauv ntawm qhov qis ntawm lub hwj chim faib txee, thiab dai rau (faiv fab tsis ua hauj lwm) kos npe.

(3) Qhia rau cov neeg ua haujlwm hauv chaw ua haujlwm kom tshem tawm lub tshuab hluav taws xob thiab txiav tawm lub zog mus rau lub qhov cub induction melting.

(4) Thaum lub sijhawm ua haujlwm ntawm lub tshuab hluav taws xob inverter, cov cuab yeej hluav taws xob yuav tsum tau kaw thiab saib xyuas raws li qhov xav tau. Yog tias pom muaj qhov txawv txav, lub tshuab yuav tsum raug kaw thiab qhov ua rau yuav tsum tau kuaj tam sim ntawd, thiab kev ua haujlwm tuaj yeem txuas ntxiv tom qab qhov kev ua txhaum raug tshem tawm.

(5) Thaum lub sijhawm ua haujlwm ntawm lub tshuab hluav taws xob inverter, yog tias cov dej xau los yog thaiv tau pom nyob rau hauv txoj kev dej thiab cov khoom siv dej txias, lub tshuab yuav tsum raug kaw thiab kuaj xyuas thiab kho. Tom qab kho thiab ziab nrog lub tshuab ziab plaub hau, nws tuaj yeem qhib thiab siv dua.

(6) Thaum lub sijhawm ua haujlwm ntawm lub tshuab hluav taws xob inverter, nws yog nruj me ntsis txwv tsis pub ua kev soj ntsuam tilting, tilting tapping, thiab kev ua haujlwm pub mis nrog lub hwj chim. Cov haujlwm saum toj no yuav tsum tau ua tom qab nres lub zog inverter.
