Izindaba - Amapharamitha angumongo kanye nezakhiwo zekhoyili yensimbi egoqelwe ngokushisayo: Ukusuka Ekukhiqizeni kuya Ekusetshenzisweni

Embonini enkulu yensimbi,Ikhoyili yensimbi egoqiwe eshisayoisebenza njengento eyisisekelo, esetshenziswa kabanzi emikhakheni efana neyokwakha, ukukhiqizwa kwemishini, kanye nemboni yezimoto. Ikhoyili yensimbi ye-Carbon, ngokusebenza kwayo okuhle kakhulu kanye nokuphumelela kwezindleko, isiphenduke into esetshenziswayo emakethe. Ukuqonda amapharamitha ayo ayisisekelo kanye nezakhiwo akubalulekile kuphela ekuthengeni izinqumo kodwa futhi kubalulekile ekwandiseni inani lempahla.

Esimeni somsebenzi wasefekthri, isisebenzi esigqoke isigqoko sokuvikela esiluhlaza kanye nevesti eliluhlaza ubukele ngokujulile ikhoyili yensimbi egoqwe ngokushisayo iphakanyiswa u-crane. Ezizungezile kunamakhoyili amaningi ensimbi agoqelwe ngokushisayo. Amakhoyili ensimbi amakhulu kanye nemvelo yefekthri ehlelekile ibonisa ukuqina kanye nokumiswa kokukhiqizwa kwensimbi nokucutshungulwa 环节，kugqamisa isikhundla esibalulekile samakhoyili ensimbi agingqike ashisayo njengento eyisisekelo ekukhiqizweni kwezimboni, futhi adlulisa umoya oqinile nokuhlelekile phakathi nokusebenza kwefekthri.

Ikhoyili yensimbi ye-ASTM A36

Ukukhiqizwa kwekhoyili yensimbi ye-Carbon kuqala ngesikhathii-carbon steel coilifektri, lapho amabhilidi acutshungulwa abe amakhoyili ezicaciso ezithile ngenqubo yokugingqika yezinga lokushisa eliphezulu. Ngokwesibonelo,Ikhoyili yensimbi ye-ASTM A36iyizinga lensimbi elivame ukusetshenziswa elicaciswe amazinga e-American Society for Testing and Materials (ASTM) futhi lifunwa kakhulu emkhakheni wokwakha kanye nobunjiniyela besakhiwo. Ikhoyili ye-ASTM A36 izidla ngamandla okukhiqiza angu-≥250 MPa kanye namandla aqinile angu-400-550 MPa, kanye ne-ductility enhle kakhulu nokushisela, ihlangabezana nezidingo zokuthwala umthwalo nokuxhuma kwezakhiwo ezinkulu ezifana namabhuloho namafreyimu asefekthri. Ukwakheka kwamakhemikhali ayo ngokuvamile kugcina okuqukethwe kwekhabhoni kungaphansi kuka-0.25%, kulinganisa ngempumelelo amandla nokuqina kuyilapho kugwenywa i-embrittlement ehambisana nokuqukethwe kwekhabhoni eyeqile.

Ngokombono wepharamitha, ukujiya, ububanzi, nesisindo sekhoyili kuyizinkomba ezibalulekile zokuhlola ukusebenza kwamakhoyili ensimbi aginqike ashisayo. Ubukhulu obujwayelekile busuka ku-1.2 ukuya ku-25.4 mm, kanti ububanzi bungadlula ku-2000 mm. Isisindo sekhoyili singenziwa ngokwezifiso, ngokuvamile sisuka kumathani ayi-10 kuye kwangama-30. Ukulawula ubukhulu obunembile akuthinti nje kuphela ukusebenza kahle kokucubungula kodwa futhi kuthinta ngokuqondile ukunemba komkhiqizo wokugcina. Isibonelo, ukubekezelela ukujiya kwamakhoyili ensimbi agingqiwe ashisayo asetshenziswa ekukhiqizeni izimoto kufanele kulawulwe ngokuqinile phakathi kuka-±0.05 mm ukuze kuqinisekiswe ubukhulu obungaguquki bezingxenye ezinesitembu.

Izidingo Zokusebenza Kwamakhoyili Ensimbi Agoqelwe Ngokushisayo Ezimbonini Ezihlukene

Izidingo zokusebenza zamakhoyili ensimbi aginqike ngokushisayo ziyahlukahluka kakhulu ezimbonini zonkana. Imboni yezokwakha ibeka phambili amandla kanye nokumelana nesimo sezulu, kuyilapho imboni yemishini ibeka phambili ukusebenza komshini nokuqedwa kwendawo. Ngakho-ke, abakhiqizi bekhoyili ye-carbon steel kufanele bavumelanise inqubo yabo yokukhiqiza nezidingo zamakhasimende. Isibonelo, izindlela ezilawulwayo zokugingqa nokupholisa zingasetshenziswa ukuze kuthuthukiswe ukwakheka kokusanhlamvu, noma izakhi zengxubevange zingangezwa ukuze kuthuthukiswe izakhiwo ezithile. Isibonelo, kumakhoyili asetshenziswa ezindaweni ezinomswakama ophezulu, ukwengezwa kwezinto ezifana ne-phosphorus nethusi kungathuthukisa ukumelana nokugqwala komkhathi.

Kusukela kunqubo yokukhiqiza yomkhiqizi wekhoyili yensimbi ye-carbon steel kuya kuzidingo zokusetshenziswa komsebenzisi wokugcina, amapharamitha angumongo kanye nezakhiwo zekhoyili yensimbi egoqelwe ngokushisayo kuhlanganiswe kulo lonke uchungechunge lokuhlinzeka. Ukuthi uthenga amakhoyili ensimbi ngobuningi noma ukhetha amakhoyili athile e-ASTM A36, ukuqonda okujulile kwezakhiwo ezibalulekile kubalulekile ukuze kuzuzwe ibhalansi efanele phakathi kokusebenza nezindleko, ukubeka isisekelo esiqinile sentuthuko yekhwalithi ephezulu kuzo zonke izimboni ezihlukahlukene.

Izigcawu eziningi zibonisa izimo zohlelo lokusebenza ezihlukene zamakhoyili ensimbi agingqiwe ashisayo

I-athikili engenhla ihlanganisa amapharamitha angukhiye kanye nezindawo zokusebenza zekhoyili yensimbi egoqelwe ngokushisayo. Uma ungathanda ukubona ukulungiswa noma imininingwane eyengeziwe, ngicela ungazise.
