Izindaba - Amapharamitha Ayinhloko Nezakhiwo Zekhoyili Yensimbi Egoqekile Eshisayo: Kusukela Ekukhiqizweni Kuya Ekusetshenzisweni

Ngaphakathi kwemboni enkulu yensimbi,ikhoyili yensimbi egoqwe ngokushisaisebenza njengezinto eziyisisekelo, ezisetshenziswa kabanzi emikhakheni efana nokwakha, ukukhiqizwa kwemishini, kanye nemboni yezimoto. I-carbon steel coil, ngokusebenza kwayo okuhle kakhulu kanye nokusebenza kahle kwezindleko, isibe yinto eyinhloko emakethe. Ukuqonda amapharamitha ayo ayinhloko kanye nezakhiwo akubalulekile nje kuphela ezinqumweni zokuthenga kodwa futhi kubalulekile ekwandiseni inani lezinto.

Esimweni somsebenzi wasefektri, ilungu labasebenzi eligqoke isigqoko sokuphepha esiluhlaza okwesibhakabhaka kanye nevesti eliluhlaza okwesibhakabhaka libukele ngokucophelela ikhoyili yensimbi egoqekile eshisayo iphakanyiswa yi-crane. Ezizungezile kukhona amakhoyili amaningi ensimbi agoqekile eshisayo abekwe kahle. Amakhoyili amakhulu ensimbi kanye nendawo ehlelekile yasefektri kubonisa ukuqina kanye nokulinganisa kokukhiqizwa kwensimbi kanye nokucubungula i-环节, kugqamisa isikhundla esibalulekile samakhoyili ensimbi agoqekile eshisayo njengento eyisisekelo ekukhiqizweni kwezimboni, futhi kuveza nesimo esiqinile nesihlelekile ngesikhathi sokusebenza kwefektri.

Ikhoyili Yensimbi ye-ASTM A36

Ukukhiqizwa kwekhoyili yensimbi yekhabhoni kuqala e-ikhoyili yensimbi yekhabhoniifektri, lapho ama-billet ecutshungulwa khona abe ama-coil anezincazelo ezithile ngenqubo yokugoqa eshisa kakhulu. Isibonelo,Ikhoyili yensimbi ye-ASTM A36iyizinga lensimbi elisetshenziswa kakhulu elichazwe yizindinganiso ze-American Society for Testing and Materials (ASTM) futhi lifunwa kakhulu emikhakheni yokwakha nobunjiniyela bezakhiwo. Ikhoyili ye-ASTM A36 inamandla okukhiqiza angu-≥250 MPa kanye namandla okudonsa angu-400-550 MPa, kanye nokuguquguquka okuhle kakhulu kanye nokushibilika, ihlangabezana nezidingo zokuthwala umthwalo kanye nokuxhumeka kwezakhiwo ezinkulu ezifana namabhuloho kanye nohlaka lwefektri. Ukwakheka kwayo kwamakhemikhali kuvame ukugcina okuqukethwe kwekhabhoni kungaphansi kuka-0.25%, kulinganisela ngempumelelo amandla nokuqina ngenkathi kugwenywa ukubhidlika okuhlobene nokuqukethwe kwekhabhoni okweqile.

Ngokombono wepharamitha, ukujiya, ububanzi, kanye nesisindo sekhoyili kuyizinkomba ezibalulekile zokuhlola ukusebenza kwamakhoyili ensimbi ashiswayo. Ubukhulu obuvamile busukela ku-1.2 kuya ku-25.4 mm, kanti ububanzi bungadlula u-2000 mm. Isisindo sekhoyili singenziwa ngokwezifiso, ngokuvamile sisukela ku-10 kuya ku-30 amathani. Ukulawulwa okunembile kobukhulu akugcini nje ngokuthinta ukusebenza kahle kokucubungula kodwa futhi kuthinta ngqo ukunemba komkhiqizo wokugcina. Isibonelo, ukubekezelela ukujiya kwamakhoyili ensimbi ashiswayo asetshenziswa ekukhiqizweni kwezimoto kumele kulawulwe ngokuqinile ngaphakathi kuka-±0.05 mm ukuqinisekisa ubukhulu obuhambisanayo bezingxenye ezigxiviziwe.

Izidingo Zokusebenza Zamakhoyili Ensimbi Agoqekile Ashisayo Ezimbonini Ezihlukene

Izidingo zokusebenza kwama-coil ensimbi ashiswayo ziyahlukahluka kakhulu kuzo zonke izimboni. Imboni yokwakha ibeka phambili amandla kanye nokumelana nesimo sezulu, kuyilapho imboni yemishini ibeka phambili ukusebenza kahle kwemishini kanye nokuphela kwendawo. Ngakho-ke, abakhiqizi be-coil yensimbi yekhabhoni kumele bavumelanise izinqubo zabo zokukhiqiza nezidingo zamakhasimende. Isibonelo, amasu okugoqa nokupholisa alawulwayo angasetshenziswa ukwenza ngcono isakhiwo sokusanhlamvu, noma izinto zokuhlanganisa zingangezwa ukuze kuthuthukiswe izakhiwo ezithile. Isibonelo, kuma-coil asetshenziswa ezindaweni ezinomswakama ophezulu, ukungezwa kwezinto ezifana ne-phosphorus nethusi kungathuthukisa ukumelana nokugqwala komoya.

Kusukela enkambisweni yokukhiqiza yomkhiqizi we-carbon steel coil kuya ezidingweni zokusetshenziswa zomsebenzisi wokugcina, amapharamitha ayinhloko kanye nezakhiwo ze-hot-rolled steel coil zixhumene kulo lonke uchungechunge lokuhlinzeka. Kungakhathaliseki ukuthi uthenga ama-steel coil ngobuningi noma ukhetha ama-ASTM A36 coil athile, ukuqonda okujulile kwezakhiwo zezinto kubalulekile ekufinyeleleni ibhalansi efanele phakathi kokusebenza kanye nezindleko, okubeka isisekelo esiqinile sentuthuko yekhwalithi ephezulu kuzo zonke izimboni ezahlukene.

Izigcawu eziningi zibonisa izimo ezahlukene zokusetshenziswa kwamakhoyili ensimbi ashisiwe

Isihloko esingenhla sihlanganisa amapharamitha abalulekile kanye namaphuzu okusebenza kwe-hot-rolled steel coil. Uma ungathanda ukubona ukulungiswa noma imininingwane eyengeziwe, ngicela ungazise.
