I-ASTM A210 Ibanga C (Ibanga C le-ASME SA210) yityhubhu yentsimbi engenamthungo ephakathi neyekhabhoni eyenzelwe ngokukodwa ukusetyenziswa ekwenziweni kweetyhubhu zebhoyila kunye neeflue zebhoyila, kubandakanya iziphelo zokhuseleko, udonga lwe-furnace kunye neetyhubhu zokuxhasa, kunye neetyhubhu ze-superheater.
Ibanga C lineempawu ezilungileyo zoomatshini, linamandla okutsalwa angama-485 MPa kunye namandla okuvelisa angama-275 MPa. Ezi mpawu, kunye nokwakheka kweekhemikhali ezifanelekileyo, zenza iityhubhu ze-ASTM A210 zebanga C zilungele ukusetyenziswa kwiindawo ezinobushushu obuphezulu kunye noxinzelelo oluphezulu kwaye zikwazi ukumelana noxinzelelo olubangelwa kukusebenza kwebhoyila.
Iityhubhu mazibe zenziwe ngenkqubo engenamthungo kwaye mazibe zigqitywe ngobushushu okanye ngokubandayo.
Apha ngezantsi kukho itshathi yenkqubo yokwenziwa kombhobho wentsimbi engenamthungo ogqityiweyo ngokubandayo:
Ngoko ke yintoni umahluko phakathi kombhobho wentsimbi ongenamthungo ogqityiweyo ngobushushu nobandayo kwaye ukhetha njani?
Igqityiwe shushuUmbhobho wentsimbi ongenamthungo ngumbhobho wentsimbi ogoqwayo okanye ogqojozwa kubushushu obuphezulu nakwezinye iinkqubo uze upholiswe ngqo kubushushu begumbi. Imibhobho yentsimbi ekule meko idla ngokuba nokuqina okungcono kunye namandla athile, kodwa umgangatho womphezulu usenokungabi mhle njengemibhobho yentsimbi egqityiweyo kuba inkqubo yonyango lobushushu inokukhokelela ekufakweni kwe-oxidation okanye ukususwa kwe-carburization kumphezulu wombhobho wentsimbi.
Igqityiwe ngokubandayoUmbhobho wentsimbi ongenamthungo ubhekisa ekucutshungulweni kokugqibela kombhobho wentsimbi ngokutsala okubandayo, ukuqengqeleka okubandayo, kunye nezinye iinkqubo kubushushu begumbi. Umbhobho wentsimbi ogqityiweyo kubanda unobuchane obuphezulu, kunye nomgangatho olungileyo womphezulu, kwaye ngenxa yokuba ukucutshungulwa kubanda kunokuphucula amandla kunye nobunzima bombhobho wentsimbi, iipropati zoomatshini zombhobho wentsimbi ogqityiweyo kubanda zihlala zingcono kunezo zombhobho wentsimbi ogqityiweyo kubanda. Nangona kunjalo, uxinzelelo oluthile olushiyekileyo lunokuveliswa ngaphakathi kombhobho wentsimbi ngexesha lokusebenza kubanda, ekufuneka kususwe ngonyango lobushushu olulandelayo.
Umbhobho wentsimbi ogqityiweyo ngobushushu awudingi unyango lobushushu.
Iityhubhu ezigqityiweyo kubanda mazifakwe i-anneal engacacanga, zifakwe i-anneal ngokupheleleyo, okanye ziphathwe ngobushushu obuqhelekileyo emva kwenkqubo yokugqibela yokugqiba ukubanda.

Uvavanyo lokuTyatya
Ukukrazuka okanye ukuqhekeka kwenzeka kwiindawo zentsimbi ye-12 ukuya kweyesi-6 kwityhubhu yeGrade C enobukhulu obuyi-2.375 in. [60.3 mm] ububanzi obungaphandle kunye nobuncinci abuyi kuthathwa njengesiseko sokwaliwa.
Iimfuno ezithile zinokujongwa kwiI-ASTM A450, into 19.
Uvavanyo lokuvutha
Iimfuno ezithile zingabonwa kwi-ASTM A450, into 21.
Ukuqina
Ibanga C: 89 HRBW (Rockwell) okanye 179 HBW (Brinell).
Umbhobho ngamnye wentsimbi kufuneka uvavanywe ngoxinzelelo lwe-hydrostatic okanye uvavanyo lombane olungatshabalalisiyo.
Iimfuno zovavanyo olunxulumene noxinzelelo lwe-hydrostatic zihambelana ne-ASTM 450, into 24.
Iimfuno zovavanyo ezinxulumene nombane ezingatshabalalisiyo ziyahambelana ne-ASTM 450, into 26.
Imisebenzi yokwenza iyimfuneko kwiityhubhu zebhoyila ukuqinisekisa ukuba iityhubhu ziyahlangabezana neemfuno ezithile zenkqubo yebhoyila.
Xa zifakwe kwibhoyila, iityhubhu kufuneka zime zikhula kwaye zibe neentsimbi ngaphandle kokubonisa iintanda okanye iziphene. Xa zisetyenziswa kakuhle, iityhubhu ze-superheater mazime zonke iinkqubo zokubumba, ukuwelda, kunye nokugoba ezifunekayo ukuze zisetyenziswe ngaphandle kokwenza iziphene.
I-Botop Steel ngumvelisi kunye nomthengisi wemibhobho yentsimbi yekhabhoni edityanisiweyo ekumgangatho ophezulu evela eTshayina, kwaye ikwangumthengisi wemibhobho yentsimbi engenamthungo, ikunika umbhobho wentsimbi okumgangatho ophezulu, osemgangathweni, kwaye oxabiso liphantsi.
