Dahaarka wuxuu ciyaara falcelin bir ah oo adag iyo isbeddel jidheed iyo kiimiko ah oo ku yimaada habka alxanka, taas oo asal ahaan ka gudubta dhibaatooyinka alxanka ee electrode sawir, sidaas darteed daahan ayaa sidoo kale ah mid ka mid ah qodobbada ugu muhiimsan ee lagu go'aamiyo tayada birta alxanka.
Dahaarka korantada:Waxa loola jeedaa lakabka dahaarka ee walax granular ah oo leh astaamo jireed iyo kiimiko oo kala duwan si isku mid ah loogu dahaadhay dusha sare ee xudunta alxanka.
Doorkaalxanka electrodedaahan:Habka alxanka, waxay samaysaa dharbaaxo leh barta dhalaalidda ku habboon, viscosity, cufnaanta, alkalinity iyo sifooyinka kale ee jirka iyo kiimikaad, si loo hubiyo gubashada arc deggan, ka dhigi birta dhibicda si sahlan u gudubka, abuurto jawi ku wareegsan aagga arc iyo barkad dhalaalaysa si loo ilaaliyo aagga alxanka, oo ay helaan samaynta alxanka wanaagsan iyo waxqabadka.Marka lagu daro deoxidizer, element alloying ama qayb ka mid ah budada birta ee daahan, waxay sidoo kale buuxin kartaa shuruudaha waxqabadka birta alxanka ama hagaajinta waxtarka dhalaalka.
Mabda'a alxanka korantada:
1. Maqaarka daawada
2. Xudunta alxanka
3. Ilaali gaaska
4: Arc
5. barkad dhalaalaysa
6. Qalabka saldhigga ah
7. Weld
8. Dharka alxanka
9. Slag
10. Dhibcaha dhalaaliya
Qalab cayriin oo kala duwan marka loo eego doorka ay ku leeyihiin daahan electrode waxaa loo qaybin karaa:
(1) Dejinta Arc
Hawsha ugu weyni waa in la sameeyo korantada si fudud si loo bilaabo qaansada oo ay ku ilaaliso gubashada arc habka alxanka.Sida arc stabilizer alaabta ceeriin inta badan qaar ka mid ah ay ku jiraan tiro go'an oo ah ionization hooseeyo iman kara si fudud ioning canaasirta, sida feldspar, sodium silicate, rutile, titanium dioxide, marble, mica, ilmenite, ilmenite la dhimay iyo wixii la mid ah.
(2) Wakiilka gaaska samaynta
Iyadoo la raacayo ficilka heerkulka sare ee gaaska burburka, samaynta jawi ilaalin ah, ilaalinta arc iyo birta dhalaalaysa, ka hortagga faragelinta oksijiinta iyo nitrogen ee hawada ku wareegsan.Walxaha gaas-samaynta sida caadiga ah loo isticmaalo waa karbohaydrayt (sida marmar, dolomite, rhombic acid, barium carbonate, iwm.) iyo walxaha organic (sida budada alwaax, istaarij, cellulose, resin, iwm.).
(3) Deoxidizer (sidoo kale loo yaqaan wakiilka yaraynta)
Maaddada ogsajiinta ee birta alxanka ku jirta waa la dhimi karaa, waxqabadka birta alxanka waxaa lagu wanaajin karaa falcelinta macdanta kiimikada ee habka alxanka.Deoxidizer inta badan waxa uu ka kooban yahay walxo bir daawaha iyo budada birta ah oo xidhiidh weyn la leh ogsijiinta.Deoxidizer sida caadiga ah loo isticmaalo waa ferromanganese, ferrosilicon, ferrotitanium, ferroaluminum, silicon calcium alloy, iwm.
(4) caagadaha
Shaqada ugu weyni waa in la wanaajiyo balaastikada, barti iyo dareeraha habka korantada ee lagu cadaadiyo daahan, wanaajiso tayada daahan ee korantada, si dusha siman ee daahan electrode uusan dillaacin.Caadi ahaan dooro dabacsanaan gaar ah, simbiriirixan ama nuugista ka dib sifooyin balaarineed gaar ah oo agab ah, sida miica, dhoobo cad, titanium dioxide, talc, galaas biyo adag, cellulose, iwm.
(5) Wakiilka Alloy
Waxaa loo isticmaalaa in lagu magdhabo gubashada walxaha alloying ee habka alxanka iyo in lagu wareejiyo walxaha alloying alxanka, si loo hubiyo in ka kooban kiimikada iyo sifooyinka biraha alxanka.Marka loo eego baahida loo qabo in la doorto noocyo kala duwan oo ferroalloys ah (sida ferromanganese, ferrosilicon, ferrochrome, birta iyo birta, ferric vanadium, ferric niobium, boron ferric, ferrosilicon dhul dhif ah, iwm) ama biraha saafiga ah (sida birta manganese, birta chromium). , budada nikkel, budada tungsten, iwm).
(6) Wakiilka dharbaaxada
Alxanka wuxuu sameyn karaa astaamo jireed iyo kiimiko gaar ah oo dhalada ah, wuxuu ilaaliyaa dhibicda alxanka iyo birta barkadda dhalaalka ah, hagaajinta sameynta alxanka, sida wakiilka slagging ee alaabta ceeriin waa marmar, fluorite, dolomite, magnesia, feldspar, dhoobo cad, mica, quartz , rutile, titanium dioxide, ilmenite, iwm.
(7) Binder
Maaddada dahaarka ayaa si adag ugu xidhan xudunta alxanka, iyo daaha korantada ayaa leh xoog gaar ah ka dib qalajinta.Habka alxanka biraha alxanka, ma jiraan wax saameyn ah oo ku yimaada barkadda alxanka iyo birta alxanka.Xirayaasha sida caadiga ah loo isticmaalo waa sodium silicate (potassium, sodium iyo sodium silicate isku dhafan) iyo resin phenolic, xanjo, iwm.
