Cam khwb cia hlau vuam

Hlau - yog, raws li paub, hlau thiab carbon hlau. Cov ntsiab lus ntawm lub yav tas yuav tsum tau ntau tshaj li ob feem pua. Nyob rau hauv lub xeev nyob rau hauv uas lub alloy yog cov pa roj carbon, paub qhov txawv grey thiab dawb hom cam khwb cia hlau. Nyob rau hauv thawj daim ntawv ntawm cov pa roj carbon yog nyob rau hauv daim ntawv ntawm graphite, nyob rau hauv lub dawb lub xeev, nws txiav txim nws zoo machinability. Txij li thaum cov dawb cam khwb cia hlau, qhov no caij yog nyob rau hauv ib tug ua txhua yam lub xeev, nws yog yuav luag tsis yooj yim sua rau weld. Thaum lub lem ntawm cov ntaub ntawv uas yog lub teeb nyob rau hauv cov xim.

Yuav ua li cas yog cov cam khwb cia hlau vuam? Peb pib nrog lub fact tias cov khoom no - tsis tus tshaj plaws haum rau no hom ntawm kev kho mob. Thaum Vuam nws deforms thiab nws yooj yim tej kab nrib pleb. Qhov no yog vim lub tshwj xeeb tsa ntawm cov pa roj carbon nyob rau hauv nws cov pob txha lov ua. Oiled cam khwb cia hlau, raws li zoo raws li cov neeg uas tau undergone raug rau ntau yam corrosive xov xwm, tsis tau welded. Qhov no, txawm li cas los, yog zoo tagnrho cov hom uas yog zoo grained thiab lub teeb grey xim nqaij daim tawv. Vuam hlau muaj kev phiv: dawb thiab raws li ib tug tshwm sim, qhov tshwm sim ntawm zos ua Vuam dawb hlau txheej uas tsis kam txais nws tus kheej tsis muaj kev kho mob; Raws li twb tau hais, tus tsim ntawm tej kab nrib pleb; ua voltage nyob rau hauv lub vuam tsam; lub weld pas dej ua ke hlau tej zaum yuav ntxeem tau vim cov pa roj carbon burnout nrog simultaneous tsim ntawm carbon dioxide. Yog li, txoj kev no ua rau ib tug ntau ntawm teeb meem. Tsis tau vuam cam khwb cia hlau yog siv heev lug. Nws muaj peb txoj kev uas: mob khaub thuas thiab kub rau semi.

Thawj yog qhov uas tsis preheating. Khaub thuas vuam ntawm cam khwb cia hlau yog ua los ntawm steel, cam khwb cia hlau thiab ua los ntawm cov uas tsis yog-ferrous co thiab alloys electrodes. Qhov loj tshaj plaws nrog rau qhov no - kom tsis txhob muaj cov mob siab heev thaum tshav kub kub nyob rau hauv lub tshav kub-cuam tshuam cheeb tsam. Rau no steel electrodes siv ib tug thawj electrode txheej superposed me me txoj kab uas hla nrog ib tug me me carbon cov ntsiab lus, ib tug nyias txheej. Amperage ntawm no theem yuav tsum tsis txhob ntau tshaj 90 amps. Tom ntej khaubncaws sab nraud povtseg yog superposed electrodes ntawm ntau dua txoj kab uas hla, lub txheej tej zaum yuav yog nyias los yog tuab.

Ib tug tseem ceeb txoj cai - nws yog xim hlau pob qij txha yuav tsum thov nrog ib tug ob peb cuam tshuam rau thaum tshav kub kub-cuam tshuam cheeb tsam kub tsis ntau tshaj rau caum degrees.

Yog hais tias lub vuam yuav tsum tau ua nyob rau hauv ib qho tseem ceeb qhov chaw, ces koj yuav siv ib tug tshwj xeeb ntaus ntawv. Qhov no thiaj li hu ua vvertyshi - tshwj xeeb studs, uas yog ua los ntawm me me hlau. Lawv lub hom phiaj - los txuas lub weld hlau nrog hlau. Vuam yog ua ua ntej, nyob ib ncig ntawm lawv, thiab ces - nyob rau hauv lub niaj zaus txoj kev. Thaum nws yog tsim nyog los weld tej casting tsis xws luag, fissures thiab tsis muaj zog cov ntsiab lus, feem ntau siv electrodes ua los ntawm alloys raws li npib tsib xee los yog tooj liab. Txhawb graphitization, lawv tiv thaiv tau qhov rov tshwm sim ntawm ib tug broad cheeb tsam ntawm tshuaj dawb tso. Vuam hlau nyob rau hauv tsev mas ua txias txoj kev. Qhov no tej zaum yuav siv tau ib yam ntawm cov hom electrodes hais saum toj no.

Kub hlau vuam yuav cua sov rau cov workpiece ua ntej kev khiav hauj lwm nrog nws. Xws li ib tug txoj kev txo cov voltage ntawm cov hlau qauv. Rau semi txoj kev - yog ib tug hloov kub. Nws yog ib tug hlau ntawm graphitization thiab los yog hauv zos cua kub mus rau ib tug tej yam kub. Cov kev siv nyob rau hauv ntau txoj kev.

Yog hais tias koj xav mus ua lub vuam ntawm ib tug neeg qhov chaw ua los ntawm cam khwb cia hlau, nyob rau hauv uas cov ntaub ntawv rau kev siv ntawm txias vuam txoj kev. Yog hais tias lub chaw ua hauj lwm yog nqa tawm ntawm cov nroj tsuag, nyob rau ib tug muaj scale, siv lub kub txoj kev.
