Rau vuam ua haujlwm, cov khoom siv hluav taws xob tas li xav tau, thiab ntau qhov ntau. Tias yog vim li cas lawv tau yuav hauv pob khoom, nyob ntawm qhov xav tau txoj kab uas hla. Hauv cov tuam txhab loj, cov khoom siv vuam vuam tau khaws cia rau hauv cov chaw tshwj xeeb, tab sis tsuas yog ob peb tus paub yuav khaws lawv li cas. Muaj lus nug txog lub txee lub neej ntawm cov electrodes. Qhov no yog ib qho tseem ceeb rau ob qho tib si rau cov lag luam loj thiab rau cov tuam txhab me uas koom nrog vuam tsuas yog qee zaus. Xav txog cov cai rau khaws cov khoom siv tseem ceeb rau kev vuam. Yuav ua li cas ncua nws lub sij hawm ntawm kev siv, vim hais tias qhov zoo ntawm kev ua hauj lwm yuav nyob ntawm seb nws?

Yuav khaws li cas?

Lub txee lub neej ntawm electrodes ncaj qha nyob ntawm seb lawv khaws cia li cas. Rau qhov no, tsis yog tsuas yog chav tsev uas tsis muaj av noo siab xwb. Nws muaj peev xwm siv cov cuab yeej tshwj xeeb uas yuav tiv thaiv qhov saum npoo ntawm cov electrodes los ntawm qhov tsis zoo ntawm ib puag ncig sab nraud.

Feem ntau, cov khoom siv hluav taws xob khaws cia hauv cov tsev khaws khoom uas nws qhuav thiab sov.

Cov cai rau khaws cov electrodes yog raws li hauv qab no:

• kub tswj+ 14 ° C;
• av noo hauv chav mus txog 50%;
• siv cua txias kom tso cua rau hauv qhov chaw kaw;
• Kev tiv thaiv lub tsev khaws khoom kom tiv thaiv kom tsis txhob ya raws.

Nws yog ib qho tseem ceeb uas yuav tsum tau ua raws li qhov ntsuas kub thiab tsis tso cai rau nws hloov pauv, vim qhov no cuam tshuam rau qhov chaw ntawm cov khoom siv rau vuam thiab qhov ua haujlwm zoo tom ntej.

Txhawm rau kom lub neej txee, koj tuaj yeem siv cov rooj tshwj xeeb, thawv lossis pallets. Tsis txhob khaws cov electrodes rau hauv pem teb vim condensation yuav ua rau lawv ntub. Koj tuaj yeem khaws lawv rau hauv ib lub thawv, tab sis yog tias koj tsis siv tag nrho ib zaug, koj yuav tsum kaw lub pob kom nruj.

Hnub Kawg ntawm electrodes

Cov yam ntxwv cia ncaj qha cuam tshuam rau lub txee lub neej ntawm cov khoom siv, uas, raws li txhua tus qauv, tuaj yeem ua tau ntev.

Txhua qhov chaw cia yuav tsum tau ua raws li cov cai ntawm GOST 9466-75 lossis GOST 9467-75. Qhov no siv rau ob qho tib si manufacturers ntawm vuam consumables thiab cov neeg muas zaub uas yuav electrodes nyob rau hauv loj qhov ntau. Txawm tias thaum thauj, cov khoom yuav tsum tsis txhob muaj kev pheej hmoo. Txawm hais tias cov khoom siv uas tau raug ya raws tuaj yeem qhuav lossis tempered.

Cov khoom siv tau tuaj yeem nyob mus ib txhis yog tias khaws cia kom raug. Yog tias muaj qee yam tsis txaus thaum kuaj xyuas sab nraud, koj tuaj yeem tshem tawm lawv los ntawm kev ziab, ntxuav lossis lwm yam haujlwm. Cov electrodes uas tau deteriorated tag yuav tsum tsis txhob siv, txawm hais tias lawv tuaj yeem siv rau kev kawm. Muajflaws yog ib qho yooj yim los txheeb xyuas qhov muag pom.

Vim li cas kuv thiaj li yuav tsum tau ci cov electrodes?

Txhawm rau tshem tawm cov av noo siab thiab txuas ntxiv lub neej txee ntawm cov electrodes, koj tuaj yeem siv cov haujlwm xws li calcination. Qhov no yog qhov tsim nyog kom lub sijhawm ua haujlwm me ntsis khoom siv puas tsuaj tsis lo rau qhov vuam.

Yuav kom ignite cov electrodes, cov tuam txhab tsim kho siv cov cuab yeej tshwj xeeb. Txhua lub pob qhib tshiab yuav tsum tau siv tag nrho. Yog tias muaj cov hluav taws xob tsis siv nyob rau hauv nws, tsis txhob muab cia rau hauv qhov chaw qhib lossis hauv qab daus.

Yuav ua li cas xaiv hom electrodes rau vuam?

Tsis paub yuav xaiv vuam electrodes li cas? Tom qab ntawd peb xav kom koj paub koj tus kheej nrog cov qauv rau lawv xaiv.

Ntawm no yog dab tsi los saib:

• Lub thickness ntawm daim hlau yuav tsum tau welded (qhov loj ntawm txoj kab uas hla ntawm cov electrodes, lub thicker cov hlau).
• qib steel (stainless steel, ferrous hlau, kub resistant, thiab lwm yam).
• Cov yam ntxwv ntawm vuam, uas yog, qhov vuam yuav siv li cas rau cov khoom (kab rov tav, ntsug, los ntawm sab saum toj mus rau hauv qab, thiab lwm yam).
• Txhim tam sim no los ntawm electrode.

Txhua hom electrode muaj nws tus kheej tam sim no, thiab cov chaw tsim khoom qhia lawv ntawm daim ntawv lo. Cov kws tshaj lij vuam siv cov qauv tshwj xeeb rau qhov no.

Ntau yam ntawm electrodes los ntawm txoj kab uas hla:

• Electrodes (2mm) -Tam sim no 40-80 A. Lawv suav hais tias yog cov khoom siv ceev tshaj plaws, txij li lawv tau tsim los rau cov ntawv nyias nyias, lawv xav tau kev txawj tshwj xeeb thiab muaj peev xwm los ua haujlwm zoo.
• Electrodes (3-3, 2 mm) - tam sim no 70-80 A (ntawm qhov tam sim no) thiab 120 A (ntawm alternating tam sim no).
• Electrodes (4 mm) - tam sim no 110-160 A. Ua haujlwm nrog cov ntawv tuab ntawm cov hlau.
• Electrodes (los ntawm 5 hli hauv txoj kab uas hla) yog cov khoom siv tshaj lij siv rau saum npoo, tsis yog vuam.

Koj paub li cas thaum cov electrodes tsis haum rau vuam?

Ntau tus neeg txaus siab tsis yog hauv cov lus nug ntawm yuav ua li cas khaws cov electrodes raws li GOST 9466-75, tab sis kuj yuav ua li cas txheeb xyuas lawv hnub tas sijhawm. Nws tsis yog ib txwm ua tau kom raug txiav txim siab txog cov xwm txheej ntawm kev khaws cia lossis kev thauj mus los, vim tias cov khoom siv hluav taws xob tuaj yeem rov qab los ntawm cov tuam txhab. Txhawm rau ua qhov no, ua qhov kev tshuaj xyuas qhov muag ntawm cov khoom siv vuam.

Yog tias cov khoom siv sab nraud zoo li tsis muaj qhov tsis xws luag, txheej txheej tsis tawg, ces cov khoom siv hluav taws xob zoo li no tseem tsim nyog rau vuam. Yog tias cov khoom siv tau, txawm tias me me, tab sis muaj qhov tsis xws luag, koj tuaj yeem ntxuav lossis ziab lawv.

Tsis txhob siv cov khoom tsis zoo lossis siv cov khoom siv thaum ua haujlwm tseem ceeb lossis cov uas xav tau qhov tseeb. Tsis tsuas yog cov tsos ntawm weld, tab sis kuj nws zoo nyob ntawm qhov no. Nco ntsoov xyuas cov electrodes ua ntej pib ua haujlwm.

Yuav ua li cas txuas lub txee lub neej ntawm cov khoom siv vuam?

GOST cov qauv khaws cia siv raucoated hlau electrodes rau phau ntawv arc vuam. Tab sis dab tsi tuaj yeem ncua lub neej txee ntawm cov khoom siv li no? Kev siv cov thermoses uas tswj tau qhov kub thiab txias hauv pob. Nws yog cov khoom siv no uas tuaj yeem txuas lub neej ntawm electrodes, tshwj xeeb tshaj yog thaum lawv siv tsis tu ncua.
