Sidee loo doortaa qalabka korantada ee mashiinka alxanka barta inta jeer ee dhexdhexaadka ah?

Sidee loo doortaa qalabka korantada ee mashiinka alxanka barta inta jeer ee dhexdhexaadka ah? Spot alxanka madaxa iyada oo kumanaan ilaa tobanaan kun oo amperes ah, u adkeysanaya danab 9.81 ~ 49.1MPa, heerkulka degdega ah ee 600 ℃ ~ 900 ℃. Sidaa darteed, electrode-ka ayaa looga baahan yahay inuu yeesho koronto wanaagsan, dabeecad kuleyl ah, qallafsanaanta kulaylka iyo iska caabinta daxalka sare.

Elektroodhada alxanka ee barta waxay ka samaysan yihiin alloys naxaas ah. Si loo hagaajiyo waxqabadka electrodes daawaha copper, guud ahaan waa lagama maarmaan in la maro xoojinta daaweynta, sida: xoojinta processing qabow, Xoojinta xal adag, xoojinta roobka gabowga iyo xoojinta kala firdhiso. Waxqabadka korantada ayaa sidoo kale isbeddela ka dib daaweynta xoojinta kala duwan. Marka taarikada birta ah ee qabow-duuban, taarikada birta galvanized, birta aan lahayn ama aluminiumku waxay u baahan yihiin in la isku dhejiyo, qalabka korantada ee ku habboon waa in lagu doortaa si waafaqsan sifooyinka alaabta saxanka.

Doorashada qalabka korantada ee booska alxanka saxan birta galvanized waa in la yareeyo wasakhda iyo qallooca ee electrode inta lagu guda jiro alxanka kaalinta, taas oo u baahan engegan sare, koronto wanaagsan iyo conductivity kulaylka ee electrode heerkulka sare, iyo u janjeera alloying yar la zinc.

Nolosha korantada ee alxanka saxan birta galvanized oo leh qalab koronto ah oo dhowr ah ayaa ka dheer kan korantada cadmium. Sababtoo ah inkasta oo korantada iyo kulaylka kuleylka cadmium copper ay ka fiican tahay, guud ahaan waxaa la aaminsan yahay in xajinta zinc ay yar tahay, laakiin dhab ahaantii, sababtoo ah heerkulka jilicsan ee hooseeya, saameynta heerkulka sare ee adag ayaa ka weyn. Heerkulka sarreeya ee naxaasta zirconium ayaa ka sarreeya, sidaas darteed nolosheeda ayaa sidoo kale dheer. In kasta oo adkaanta heerkulka sare ee dheemanka beryllium uu sarreeyo, sababtoo ah dhaqdhaqaaqiisu aad ayuu uga xun yahay kan chromium-zirconium copper, conductivity iyo kulaylka kuleylku waxay door weyn ka ciyaaraan saameynta nolosheeda, nolosheeda electrode waa mid aad u hooseeya.

Intaa waxaa dheer, isticmaalka tungsten (ama molybdenum) gundhig isku dhafan electrode alxanka galvanized saxan bir ah, nolosheeda ayaa sidoo kale ka sarreeya, inkastoo conductivity ee tungsten, molybdenum hooseeyo, oo kaliya oo ku saabsan 1/3 ee copper chromium, laakiin heerkulka jilcin waa sare. (1273K), qallafsanaanta heerkulka sare (gaar ahaan tungsten), korantada ma fududa in la beddelo.
