Q1: Cov khoom siv vuam yog dab tsi?Yuav suav nrog dab tsi?
Teb: Cov khoom siv vuam muaj xws li vuam rods, vuam hlau, fluxes, gases, electrodes, gaskets, thiab lwm yam.
Q2: Acid electrode yog dab tsi?
Teb: Cov txheej txheej ntawm cov kua qaub electrode muaj ntau cov kua qaub oxides xws li SiO2, TiO2 thiab ib qho ntawm cov carbonate, thiab cov alkalinity ntawm cov slag yog tsawg dua 1. Titanium electrodes, calcium titanium electrodes, ilmenite electrodes thiab hlau oxide. electrodes yog tag nrho cov kua qaub electrodes.
Q3: Dab tsi yog alkaline electrode?
Teb: Alkaline electrode txheej muaj ntau cov alkaline slag-forming cov ntaub ntawv xws li marble, fluorite, thiab lwm yam., thiab muaj ib co deoxidizer thiab alloying tus neeg sawv cev.Tsawg-hydrogen hom electrodes yog alkaline electrodes.
Q4: Dab tsi yog cellulose electrode?
Teb: Cov txheej electrode muaj cov ntsiab lus cellulose siab thiab ruaj khov arc.Nws decomposes thiab tsim ib tug loj npaum li cas ntawm cov roj los tiv thaiv lub vuam hlau thaum lub sij hawm vuam.Hom electrode no tsim cov slag me me thiab yooj yim tshem tawm.Nws tseem hu ua ntsug downward vuam electrode.Nws tuaj yeem welded hauv txhua txoj haujlwm, thiab ntsug vuam tuaj yeem welded downwards.
Q5: Vim li cas cov electrode yuav tsum tau qhuav nruj me ntsis ua ntej vuam?
Vuam rods zoo li deteriorate cov txheej txheem kev ua tau zoo vim yog noo noo nqus, ua rau tsis ruaj tsis khov arc, nce spatter, thiab yooj yim los tsim pores, tawg thiab lwm yam tsis xws luag.Yog li ntawd, lub vuam pas nrig yuav tsum tau qhuav nruj me ntsis ua ntej siv.Feem ntau, qhov ziab ntawm cov kua qaub electrode yog 150-200 ℃, thiab lub sij hawm yog 1 teev;Lub ziab kub ntawm alkaline electrode yog 350-400 ℃, lub sij hawm yog 1-2 teev, thiab nws yog qhuav thiab muab tso rau hauv ib lub incubator ntawm 100-150 ℃ Sab hauv, coj nws raws li koj mus.
Q6: Dab tsi yog welding hlau?
Teb: Nws yog cov hlau hlau uas siv los ua cov hlau nplaum thaum lub sij hawm vuam thiab siv rau kev siv hluav taws xob tib lub sij hawm-hu ua vuam hlau.Muaj ob hom: khoom hlau thiab flux-cored hlau.Feem ntau siv cov khoom siv vuam hlau qauv: (GB-lub teb chaws tus qauv ntawm Tuam Tshoj) ER50-6 (chav kawm: H08Mn2SiA).(AWS-American Standard) ER70-6.
Q7: Dab tsi yog flux cored vuam hlau?
Teb: Ib hom vuam hlau ua los ntawm nyias steel strips dov mus rau hauv cov kav hlau puag ncig thiab ntim nrog qee yam muaj pes tsawg leeg ntawm cov hmoov.
Q8: Vim li cas qhov flux cored hlau tiv thaiv los ntawm cov pa roj carbon dioxide?
Teb: Muaj plaub hom flux-cored vuam hlau: acidic flux-cored gas shielded vuam hlau (titanium hom), alkaline flux-cored roj shielded vuam hlau (titanium calcium hom), hlau hmoov hom flux-cored roj shielded vuam hlau thiab flux-cored self-shielded vuam hlau.Cov titanium hom flux-cored gas shielded vuam hlau feem ntau tiv thaiv los ntawm CO2 roj;lwm cov flux-cored vuam hlau yog tiv thaiv los ntawm cov roj sib xyaw (thov saib cov lus qhia ntawm flux-cored hlau).Cov tshuaj tiv thaiv metallurgical ntawm txhua cov roj slag mis sib txawv, thov tsis txhob siv cov roj tiv thaiv tsis raug.Flux-cored vuam hlau roj slag ua ke kev tiv thaiv, zoo vuam seam tsim, siab zoo txhua yam khoom.
Q9: Vim li cas thiaj muaj cov kev cai rau kev ua kom huv ntawm cov pa roj carbon dioxide?
Teb: Feem ntau, CO2 roj yog cov khoom siv los ntawm kev tsim tshuaj lom neeg, nrog rau purity tsuas yog li 99.6%.Nws muaj cov cim ntawm impurities thiab noo noo, uas yuav ua rau muaj qhov tsis xws luag xws li qhov pores rau qhov vuam.Rau cov khoom siv vuam tseem ceeb, roj nrog CO2 purity ≥99.8% yuav tsum tau xaiv, nrog cov pores tsawg dua hauv cov vuam, cov ntsiab lus tsis tshua muaj hydrogen, thiab cov kab nrib pleb zoo.
Q10: Vim li cas thiaj muaj kev xav tau ntau dua rau argon purity?
Teb: Tam sim no muaj peb hom argon nyob rau hauv kev ua lag luam: dawb argon (purity ib ncig ntawm 99.6%), ntshiab argon (purity ib ncig ntawm 99.9%), thiab high-purity argon (purity 99.99%).Thawj ob tuaj yeem welded rau carbon steel thiab stainless hlau.High-purity argon yuav tsum tau siv rau vuam non-ferrous hlau xws li txhuas thiab txhuas alloys, titanium thiab titanium alloys;kom tsis txhob oxidation ntawm weld thiab tshav kub-cuam tshuam cheeb tsam, high-zoo thiab zoo nkauj weld tsim yuav tsis tau.
