Li-Fasteners tsa Alloy Steel: Matla, Khanyetso, le Hobaneng li Bohlokoa
Alloy Steel Fasteners ke Eng?
Lisebelisoa tsa tšepe tsa alloy li entsoe ka tšepe e matlafalitsoeng ka likarolo tse ling - joalo ka chromium, molybdenum, nickel, kapa vanadium - ho ntlafatsa lisebelisoa tse khethehileng tsa mochini. Li-additives tsena li lumella litšepe tsa alloy ho feta tšepe e tloaelehileng ea carbon ho ea ka matla, ho thatafala, ho hanyetsa kutu, le ho mamella mocheso.
U tla fumana tšepe ea alloy e sebelisoa mefuteng e mengata ea li-fasteners: liboutu tsa hex, li-socket screws, li-studs, le tse ling. Ho feto-fetoha ha tsona ho etsa hore e be khetho ea ho khetha bakeng sa lisebelisoa tse boima le tse nepahetseng.
Ke Hobane'ng ha Matla a le Bohlokoa ho Li-Fasteners
Lits'ebetsong tseo ho tsona ho sisinyeha, khatello, kapa mocheso o feteletseng e leng karolo ea tikoloho, ho hlōleha ha li-fasteners ho ka bitsa chelete e ngata—kapa ho kotsi. Li-fasteners tsa tšepe tsa alloy li fana ka matla a holimo le ho hlahisa matla ha li bapisoa le litšepe tse bonolo kapa tse tloaelehileng tsa k'habone, li li fa moeli o betere oa polokeho tlas'a khatello ea maikutlo.
Sena se etsa hore li tšoanelehe haholo bakeng sa liindasteri tse kang:
-
Oli le Khase- moo likarolo li tlamehang ho mamella khatello le tikoloho e senyang.
-
Sepakapaka- moo boima ba 'mele, ho thothomela, le ho atolosoa ha mocheso ke lintlha tse sa khaotseng.
-
Lisebelisoa tsa likoloi & tse boima- moo li-fasteners li tlamehang ho sebetsana le tšusumetso, ho sisinyeha, le mojaro o telele.
Corrosion le Heat Resistance
Lintho tse kopanyang ha li matlafatse matla feela - li boetse li ntlafatsa tsela eo tšepe e sebetsang ka eona tlas'a maemo a thata a tikoloho. Ka mohlala:
-
Chromiume eketsa ho hanyetsa mafome le oxidation.
-
Molybdenume matlafatsa matla ka mocheso o phahameng.
-
Nickele thusa ho ntlafatsa ho tiea le ho hanyetsa mokhathala.
Litšobotsi tsena li etsa hore li-fasteners tsa tšepe tsa alloy e be khetho e ntle bakeng sa ts'ebeliso ea kantle, ts'ebeliso ea metsing, le lits'ebetso tse pepesehileng ho palama baesekele e futhumetseng.
Mephato le Maemo a ho Tseba
Ha ho na boholo bo lekanang-bohle ha ho tluoa ho tšepe ea alloy. Ho ipapisitsoe le litlhoko tsa projeke ea hau, u ka khetha li-fasteners tse kentsoeng tlas'a maemo a kang ASTM A193 (hangata bakeng sa mocheso o phahameng, lits'ebetso tsa khatello e phahameng) kapa SAE Kereiti ea 8 (e tsejoang ka matla a phahameng a tensile).
Ho utloisisa sehlopha se nepahetseng ho thusa ho netefatsa hore li-fasteners li fihlela litlhoko tsa polokeho le ts'ebetso ntle le litšenyehelo tse sa hlokahaleng kapa boenjiniere bo feteletseng.
Ho Khetha Fastener e Nepahetseng bakeng sa Mosebetsi
Ho khetha mochine o motle ka ho fetisisa oa tšepe ea alloy ho bolela ho nahana ka setšoantšo se feletseng-maemo a mojaro, ho pepesehela mongobo kapa lik'hemik'hale, ho fetoha ha mocheso, esita le boiketlo ba ho kenya. Mohlala, sekoti se matla a holimo se ka sebetsa hantle bakeng sa libaka tse thata, athe hex bolt e ka fana ka torque e betere le ho ts'oara likopanong tsa meralo.
Hase feela hore na ke lintho life tse kopanyang lintho—ke tse li bolokang li le hammoho tlas’a khatello.
Mabapi le Fasto
Ho Fasto, re sebetsa ka thata ho fana ka litharollo tse tšepahalang, tse sebetsang hantle tse ts'eptjoang ke baenjiniere le bahlahisi lefatšeng ka bophara. Hore na o sebetsana le lintlafatso tsa motlakase, lipalangoang kapa mochini o boima, boitlamo ba rona ba boleng bo netefatsa hore karolo e 'ngoe le e 'ngoe eo re fanang ka eona e etselitsoe ho sebetsa-'me e hahiloe hore e tšoarelle. Ka ho shebana le ho nepahala, matla le tšehetso, Fasto e u thusa ho hokahanya likarolo tse bolokang lefatše la hau le ntse le tsamaea.
