Dhuumaha birta ee shubka nodular
Faahfaahinta Alaabta
Tuubooyinka birta ah ee birta ah ee Nodular-ka ah ayaa asal ahaan ah tuubooyinka birta ductile, kuwaas oo leh nuxurka birta iyo sifooyinka birta, sidaas darteed magacooda.Graphite ee tuubooyinka birta ductile waxay u jirtaa qaab wareegsan, oo cabbirkeedu guud yahay 6-7 darajo.Marka la eego tayada, heerka spheroidization ee tuubooyinka birta ah ayaa loo baahan yahay in lagu xakameeyo heerarka 1-3, oo leh heerka spheroidization ee ≥ 80%.Sidaa darteed, sifooyinka farsamada ee maadada lafteeda ayaa la hagaajiyay, iyada oo lahaanshaha nuxurka birta iyo sifooyinka birta.Ka dib markii la tirtiro, qaab-dhismeedka microstructure ee tuubooyinka birta birta ah waa ferrite leh qadar yar oo pearlite ah, kaas oo leh sifooyin farsamo oo wanaagsan, sidaas darteed waxaa sidoo kale loo yaqaannaa tuubooyinka birta birta ah.

1.Waxqabadka iska caabinta cadaadiska gudaha:
birta ductile centrifugal waxay leedahay nuxurka birta iyo waxqabadka birta, markaa tuubooyinka birta ee birta ah waxay leeyihiin waxqabad ammaan oo aad u fiican marka loo eego tuubooyinka laga sameeyo alaabta kale.Cadaadiska shaqada ee loo qaabeeyey aad ayuu uga sarreeyaa kan tuubooyinka laga sameeyay maaddooyinka kale, qodobka badbaadada ayaa aad u sarreeya, cadaadiska qarxinta suurtagalka ah waa
saddex jeer cadaadiska shaqada.
2.Waxqabadka iska caabinta cadaadiska dibadda:
Cadaadiska cadaadiska sare wuxuu ka fogaan karaa baahida sariirta tuubada iyo daboolka ilaalinta, taasoo ka dhigaysa tuubooyinka dhigista mid la soo celin karo iyo mid dhaqaale.
3.Lakabka ka-hortagga daxalka gudaha:
Lakabka gudaha ee tuubooyinka birta ductile waxaa si centrifugalally lagu buufiyaa hoobiye sibidhka.Dahaarka sibidhka wuxuu u hoggaansamaa heerka caalamiga ah ee ISO4179, isagoo hubinaya in hoobiyeku uu xooggan yahay oo siman yahay.Dahaarka mootada ma dhici doonto ama ma xumaan doono, dhumucdiisuna waxay xaqiijinaysaa in biyaha la cabbo ee ay wareejiyaan tuubooyinka ay helaan difaac wanaagsan.
4.Daahan ilaalinta:
Ku buufinta zinc ee tuubooyinka birta ductile waxay ilaalin karaan tuubooyinka si firfircoon iyada oo loo marayo saameynta korantada ee zinc iyo birta.Rinjiga resin-ka sare ee loo yaqaan 'chiorinated resin', tuubooyinku waxay heli doonaan ilaalinta ka hortagga daxalka.Dusha sare ee zinc tuubo kasta kama yarayn 130g/m², waxayna u hoggaansantaa heerka ISO8179.Waxaan sidoo kale kordhin karnaa dhumucda buufinta zinc ama buufin karnaa lakabka aluminium ee zinc iyo aluminium iyadoo loo eegayo baahida macaamiisha.
Astaamaha
Dhuumaha birta birta ah waa nooc ka mid ah tuubooyinka birta ee shubka ah.Marka la eego tayada, heerka spheroidization ee tuubooyinka birta ah ayaa loo baahan yahay in lagu xakameeyo heerarka 1-3 (heerka spheroidization> 80%), sidaas darteed hagaajinta sifooyinka farsamada ee maaddada lafteeda, haysashada nuxurka birta iyo sifooyinka birta. .Tuubbada birta ah ee la jeexjeexay waxay leedahay qaab-dhismeedka metallographic of ferrite oo leh qadar yar oo pearlite ah, kaas oo leh sifooyin farsamo oo wanaagsan, waxqabadka ka hortagga daxalka, ductility wanaagsan, saameyn shaabad wanaagsan, rakibid fudud, waxaana inta badan loo isticmaalaa sahayda biyaha, gudbinta gaaska. , gaadiidka shidaalka, iwm. ee shirkadaha dawladda hoose iyo warshadaha.
Waxaa jira xaddi go'an oo garaafyo wareegsan ah oo lagu qaybiyay matrixka ferrite iyo pearlite.Iyada oo ku xidhan dhexroorka magacaaban iyo shuruudaha dhererka, saamiga ferrite iyo pearlite ee qaab dhismeedka matrix way kala duwan yihiin.Qaybta pearlite ee dhexrooryada yaryar guud ahaan kama badna 20%, halka dhexroorka waaweyn guud ahaan lagu xakameynayo qiyaastii 25%.
Codsiga
Tuubooyinka birta ah ee birta ah ayaa lagu heli karaa dhexroor kala duwan oo ka bilaabma 80mm ilaa 1600mm waxayna ku habboon yihiin gudbinta biyaha la cabbi karo iyo qaybinta labadaba (sida waafaqsan BS EN 545) iyo bulaacada (sida waafaqsan BS EN 598). , waxaa la dhigi karaa dhammaan xaaladaha cimilada iyo inta badan iyada oo aan loo baahnayn dib u buuxin la doortay.Qodobkeeda badbaadada sare iyo awoodda lagu daboolayo dhaqdhaqaaqa dhulka ayaa ka dhigaya walxaha dhuumaha ee ugu fiican ee codsiyo kala duwan.
