Cov txheej txheej ua lub luag haujlwm hauv cov tshuaj tiv thaiv metallurgical complex thiab lub cev thiab tshuaj hloov pauv thaum lub sij hawm vuam txheej txheem, yeej kov yeej cov teeb meem ntawm lub teeb electrodes thaum vuam, yog li cov txheej kuj yog ib qho tseem ceeb uas txiav txim siab qhov zoo ntawm cov hlau vuam.
Electrode txheej: yog hais txog cov txheej txheej txheej uas yog coated nyob rau saum npoo ntawm vuam cores los ntawm kev sib txuas cov khoom nplua-grained nrog cov khoom sib txawv ntawm lub cev thiab tshuaj lom neeg.
Lub luag haujlwm ntawm cov txheej txheem electrode: tsim cov slag nrog lub cev thiab tshuaj lom neeg cov khoom xws li melting point, viscosity, ntom, thiab alkalinity thaum lub sij hawm vuam txheej txheem, kom ruaj khov arc combustion, ua rau cov droplet hlau yooj yim rau kev hloov, thiab ua. nyob ib ncig ntawm arc cheeb tsam thiab molten pas dej ua ke Tsim kom muaj huab cua los tiv thaiv qhov chaw vuam, thiab tau txais cov vuam zoo thiab kev ua haujlwm zoo.
Nws kuj tseem tuaj yeem ntxiv cov deoxidizers, cov ntsiab lus alloying lossis qee yam ntawm cov hmoov hlau rau cov txheej txheem kom ua tau raws li qhov yuav tsum tau ua ntawm vuam hlau kev ua tau zoo lossis txhim kho kev ua haujlwm zoo.
Xinfa vuam cov ntaub ntawv muaj zoo heev, thov mus saib kom paub meej:https://www.xinfatools.com/welding-material/
Electrode arc vuam txoj cai 1. Tshuaj tawv nqaij 2. Solder core 3. Tiv thaiv roj 4. Arc 5. Melt pas 6. Base khoom 7. Weld 8. Vuam slag 9. Slag 10. Droplets
Ntau yam khoom siv raw tuaj yeem muab faib ua:
(1) arc stabilizer
Lub luag haujlwm tseem ceeb yog ua kom cov electrode yooj yim los tawm tsam lub arc thiab ua kom lub arc hlawv ruaj khov thaum lub sijhawm vuam.Cov ntaub ntawv raw siv los ua arc stabilizers yog cov khoom uas muaj qee yam ntawm cov ntsiab lus yooj yim ionized nrog tsawg ionization peev xwm, xws li feldspar, dej iav, rutile, titanium dioxide, marble, mica, ilmenite, txo ilmenite, thiab lwm yam.
(2) Gas generating tus neeg sawv cev
Cov pa roj yog decomposed nyob rau hauv lub siab kub ntawm lub arc, tsim ib tug tiv thaiv huab cua, tiv thaiv lub arc thiab molten pas dej ua ke hlau, thiab tiv thaiv intrusion ntawm oxygen thiab nitrogen nyob rau hauv ib puag ncig huab cua.Feem ntau siv cov khoom tsim hluav taws xob yog cov carbonates (xws li marble, dolomite, magnesite, barium carbonate, thiab lwm yam) thiab cov organic (xws li ntoo hmoov, hmoov txhuv nplej siab, cellulose, resin, thiab lwm yam).
(3) Deoxidizer (tseem hu ua txo tus neeg sawv cev)
Los ntawm cov tshuaj metallurgical cov tshuaj tiv thaiv hauv cov txheej txheem vuam, cov pa oxygen hauv cov hlau vuam raug txo, thiab kev ua haujlwm ntawm cov hlau vuam zoo tuaj.Deoxidizers feem ntau yog cov hlau alloys thiab lawv cov hmoov hlau uas muaj cov ntsiab lus uas muaj affinity siab rau oxygen.Feem ntau siv deoxidizers suav nrog ferromanganese, ferrosilicon, ferrotitanium, ferroaluminum, thiab silicon-calcium alloys.
(4) Plasticizer
Lub luag haujlwm tseem ceeb yog txhawm rau txhim kho cov plasticity, elasticity thiab fluidity ntawm cov txheej txheem txheej txheej ntawm electrode xovxwm txheej, txhim kho qhov zoo ntawm electrode txheej, thiab ua kom lub ntsej muag ntawm cov electrode txheej du tsis muaj cracking.Feem ntau, cov ntaub ntawv uas muaj qee yam elasticity, slipperiness lossis qee yam kev nthuav dav tom qab nqus dej raug xaiv, xws li mica, av nplaum dawb, titanium dioxide, talcum hmoov, iav dej khov, cellulose, thiab lwm yam.
(5) alloying tus neeg sawv cev
Nws yog siv los them nyiaj rau qhov kub poob ntawm alloying ntsiab thaum lub sij hawm vuam thiab hloov pauv cov ntsiab lus alloying rau hauv vuam kom ntseeg tau cov tshuaj muaj pes tsawg leeg thiab cov khoom ntawm cov hlau vuam.Ntau yam ferroalloys (xws li ferromanganese, ferrosilicon, ferrochrome, steel, ferrovanadium, ferroniobium, ferroboron, tsis tshua muaj ntiaj teb ferrosilicon, thiab lwm yam) los yog cov hlau ntshiab (xws li hlau manganese, hlau chromium, nickel hmoov, tungsten hmoov, thiab lwm yam) tuaj yeem xaiv tau. raws li kev xav tau.tos).
(6) Slagging agent
Thaum vuam, nws tuaj yeem tsim cov slag nrog qee lub cev thiab tshuaj lom neeg, tiv thaiv vuam tee thiab molten pas dej hlau, thiab txhim kho kev tsim vuam.Cov ntaub ntawv nyoos siv los ua cov tshuaj slagging muaj xws li marble, fluorite, dolomite, magnesia, feldspar, dawb av, mica, quartz, rutile, titanium dioxide, ilmenite, thiab lwm yam.
(7) Cov ntaub ntawv
Ua kom cov khoom txheej txheej ruaj khov rau cov tub ntxhais vuam, thiab ua kom cov txheej txheem electrode muaj qee lub zog tom qab ziab.Tsis muaj kev cuam tshuam rau lub pas dej molten thiab vuam hlau thaum vuam metallurgy.Feem ntau siv binders yog iav dej (potassium, sodium thiab lawv cov iav dej sib xyaw), phenolic r
