Electrodes steel steel CB-A102
Isticmaalka elektiroonigga birta ah ee aan lahayn ogaysiis
1. chromium ahama waxay leedahay iska caabin daxalka qaarkood (oxidizing acid, organic acid, cavitation) , iska caabin kulaylka iyo xidhashada caabbinta.Caadi ahaan waxaa loo isticmaalaa warshadaha korontada, kiimikooyinka, batroolka iyo qalabka kale ee qalabka.Chromium birta aan fiicnayn alxanka liidata, waa in fiiro gaar ah u leh habka alxanka, xaaladaha daaweynta kulaylka iyo xulashada korantada ku habboon.
2. CR-13 birta aan lahayn waxay leedahay adayg sare ka dib alxanka waana ay fududahay in la soo saaro dildilaaca.Haddii nooc la mid ah chromium ahama electrode (G202, G207) loo isticmaalo alxanka, waa in preheated in ka badan 300 ° C oo la qaboojiyey ilaa 700 ° C alxanka ka dib.Haddii alxanka aan la fulin karin daaweynta kulaylka post-alxanka, ka dibna doorashada ee chromium-nickel ahama electrode (A107, A207) .
3. Chromium 17 ahama, si loo hagaajiyo caabbinta daxalka iyo alxanka iyo kordhinta qadarka habboon ee walxaha xasiloonida sida Ti, Nb, Mo, iwm, alxanka ayaa ka fiican chromium 13 birta aan lahayn.Marka la isticmaalo nooc isku mid ah ee chromium ahama electrode (G302, G307), waa in horay loo sii kululeeyaa 200 ° C oo lagu kululeeyaa 800 ° C alxanka ka dib.Haddii alxanka aan lagu daweyn karin kulaylka, markaa doorashada chromium-nickel steel electrode (A107, A207) .CR-NI qalabka birta ah ee birta ah waxay leedahay iska caabin daxalka wanaagsan iyo iska caabbinta oksaydhka, oo si ballaaran loogu isticmaalo warshadaha kiimikada, bacriminta, batroolka, soosaarka mishiinnada caafimaadka.
4. 0 iyo wixii ka hooseeya waxaa loo isticmaali karaa alxanka booska oo dhan.
5.0 iyo wixii ka sareeya alxanka fidsan iyo alxanka fillet.
6. Chromium-nickel daahan birta aan lahayn ayaa leh nooca titanium-calcium iyo nooca hydrogen hooseeya.Nooca titanate kalsiyum waxaa loo isticmaali karaa AC iyo DC, laakiin dhexgalka ee alxanka AC-gacmeed, halka ay fududahay in la caseeyo, si loo isticmaalo sahayda DC.Dhexroorka
7. Electrode waa in lagu hayaa qalalan, nooca titanium-calcium waa in lagu qallajiyaa 150 ° C 1 saac, nooca hydrogen yarna waa in lagu qallajiyaa 200 ° C ilaa 250 ° C 1 saac (ma qallajin soo noqnoqda, haddii kale dahaarka waa sahlan tahay in la dillaaciyo oo la dilo) , ka ilaali dahaarka korantada ee saliidda iyo wasakhda kale, si aanay u kordhin maadada kaarboonka ee alxanka oo saameyn ku yeelata tayada alxanka.
8. Si looga hortago daxalka u dhexeeya indhaha ee uu keeno kuleyliyaha, hadda alxanka waa inuusan noqon mid aad u weyn, oo ka yar korantada birta kaarboon qiyaastii 20%, ARC waa inaysan noqon mid aad u dheer, qaboojin degdeg ah oo u dhexeeya lakabyada, si loo cidhiidhiyo boodhka .
