SAW yog dab tsi (Submerged arc vuam)?
Submerged arc vuam (SAW) yog ib txoj kev uas submerged arc hlau siv los ua electrode thiab cov arc hlawv hauv granular, fusible flux. Vim tias lub dab da dej sib xyaw muaj kev tiv thaiv zoo, kev ua haujlwm zoo, qib siab ntawm qib siab, qhov kev tso siab ceev, yooj yim kho qhov weld alloy system tuaj yeem txais yuav qhov loj vuam tshwj xeeb, muaj kev thov tshwj xeeb rau vuam txoj haujlwm, qhov ntev ntawm txoj kev vuam no feem ntau siv hauv qee yam txoj hauj lwm ntawm vuam, xws li lub siab ntim, tshuab hnyav, dav taub loj ntawm cov roj thiab cov nkev, thauj cov tshuab, nkoj, thiab lwm yam. Qhov ntev ntawm cov tog zaum, ntev ncaj ncaj, loj loj ntawm vuam sib tsoo, thiab lwm yam
SAW EM12k vuam hlau yog dab tsi?
SAW EM12k vuam hlau yog tooj liab carbon cov txheej txheem hlau xov hlau, nrog cov coj sib dhos rau tsis siv neeg arc vuam; vuam hlau muaj cov yam ntxwv zoo tshuab.
Daim Ntawv Thov: Haum rau kev siv lub tshuab tsis siv lub tshuab ua haujlwm ntawm lub rhaub dej, lub nkoj siab thiab cov nkoj nqus dej ntawm cov pa roj carbon steel thiab alloys nrog qib qis zog, xws li 16Mn.
Dab tsi yog qhov zoo ntawm submerged arc vuam EM12k vuam hlau?
1. Cov khoom muaj txiaj ntsig zoo: thaum submerged arc vuam hlau tawm los ntawm qhov ntev ntawm cov conductive nozzle ntev yog luv dua, tuaj yeem siv qhov hluav taws xob loj dua, cov coj tam sim no ntom ntom tseem loj dua, ntxiv rau flux thiab kub rwb thaiv tsev nyhuv ntawm molten slag, siab thermal efficiency, cov kev sib nkag yog loj dua, nruab nrab thickness phaj qhib Kuv tuaj yeem weld nkag mus rau hauv qhov zawj, lossis vuam vias qhov loj me tuaj yeem txo qis dua, txo cov txheej txheem muab tub lim hlau, yog li ntawd, submerged arc vuam vuam nrawm nrawm tuaj yeem nrawm dua, khoom lag luam zoo.
2. Lub qhov rooj hlau tsis zoo: kev tiv thaiv slag yog tau txais thaum lub sijhawm sib txuas hauv arc vuam, uas tsis tuaj yeem tsuas yog cais cov huab cua sab nraud, tab sis kuj tseem ua rau cov cua txias ceev ntawm lub pas nrig hlau, kom cov kua hlau muaj ntau lub sijhawm los ua cov tshuaj tiv thaiv metallurgical nrog molten flux , txo qhov ua tau ntawm pores, kab nrib pleb thiab lwm yam tsis xws luag. Tus flux tseem tuaj yeem ua cov metallurgical cov tshuaj tiv thaiv thiab hloov qee cov ntsiab lus sib txuas nrog lub vuam hlau, yog li txhim kho qhov tsis zoo ntawm weld. Lub caij no, daim ntawv thov ntawm kev hloov kho tsis siv neeg thiab tswj kev siv tshuab hauv submerged arc vuam ua rau cov txheej txheem vuam ruaj khov thiab weld zoo li thiab zoo nkauj.
3. Txuag cov ntaub ntawv vuam siv hluav taws xob thiab lub zog hluav taws xob: Xa subcc arc vuam tuaj yeem qhib qhov zoo li i-puab zawj lossis lub kaum-qhov me me sib tsoo vim cov cua nkag loj, uas ua rau txo cov khoom siv hlau. Tsis tas li ntawd, nws muaj kev tiv thaiv los ntawm flux thiab slag los txo cov hlau txaws poob thiab qhov kub hnyiab, yog li txuag cov khoom siv vuam thiab hluav taws xob.
4. Cov kev ua haujlwm tau zoo: Xa mus rau arc vuam yog kev siv tshuab, yog li kev siv lub zog yog tsawg. Tsis tas li ntawd, arc hlawv nyob hauv qab txheej flux, tsis muaj teeb meem roj ntau qhov khiav dim, thiab tsis muaj hluav taws xob arc, uas tsis tshua muaj kev puas tsuaj rau lub welder' s lub cev.
Dab tsi yog qhov tsis zoo ntawm kev nqus dej arc vuam?
1. Raws li puag ncig ntawm arc vuam vias vias yog npog los ntawm flux, nws tsis yooj yim los soj ntsuam hauv cov txheej txheem vuam, yog li nws tsis zoo rau kev kho kom raws sijhawm.
Vim tias submerged arc vuam tso siab rau kev txuam nrog ntau cov flux los ua qhov kev tiv thaiv kev tiv thaiv, nws yog qhov tsim nyog rau vuam vias txoj hauj lwm, thiab cov kev ntsuas tshwj xeeb yuav tsum tau ua rau vuam hauv lwm txoj haujlwm.
2. Raws li lub ntsiab ntawm submerged arc vuam flux yog MnO, SiO2 thiab lwm yam hlau thiab tsis muaj hlau tsis zoo, nws nyuaj rau weld aluminium, titanium thiab lwm yam hlau nrog muaj zog oxidation yam ntxwv thiab lawv cov alloys.
3. Vim tias qhov tsis muaj qhov txav tsis zoo thiab cov khoom siv vuam siv tsis zoo, nws tsis haum rau vuam ntawm qhov txuas luv, thiab nws nyuaj rau weld qee qhov tsis txuas hlau.
4.Submerged arc vuam muaj qhov tsis zoo arc ruaj khov thaum lub vuam tam sim no tsawg dua 100A, yog li nws tsis haum rau nyias daim hlau nrog vuam thickness tsawg dua 1 hli.
