Insimbi yesigaba ingenye yezinhlobo ezine ezinkulu zensimbi (ipuleti, ishubhu, iphrofayili, ucingo). Ngokwesimo sesigaba, insimbi yesigaba ihlukaniswe ngensimbi yesigaba esilula kanye nensimbi yesigaba esiyinkimbinkimbi (insimbi yesigaba). Owokuqala ubhekisela ensimbi yesikwele, insimbi eyindilinga, insimbi eyisicaba, insimbi ye-engeli, insimbi ene-hexagonal, njll.; lokhu kokugcina kubhekisela ku-I-beam, insimbi yesiteshi, isitimela sensimbi, insimbi yohlaka lwamafasitela, insimbi egobile, njll.
Insimbi eyisicaba eyisicaba ingasetshenziselwa ukwenza ama-ayini ayindilinga, amathuluzi nezingxenye zemishini njengempahla eqediwe, futhi isetshenziswe njengezingxenye zesakhiwo sendlu yohlaka kanye nezitebhisi ezizihambelayo ekwakheni.
Inqubo ye-galvanizing
I-hot-dip galvanizing ibizwa nangokuthi i-hot-dip galvanizing kanye ne-hot-dip galvanizing: iyindlela ephumelelayo yokulwa nokugqwala kwensimbi, esetshenziswa kakhulu ezindaweni zesakhiwo sensimbi ezimbonini ezihlukahlukene. Izingxenye zensimbi ezikhishwe ukugqwala zicwiliswa kwisisombululo se-zinc esincibilikisiwe cishe ngo-500 ° C, ukuze ungqimba lwe-zinc lunamathele ebusweni bezingxenye zensimbi, ngaleyo ndlela kufezeke injongo yokulwa nokubola.
Inqubo ye-hot-dip galvanizing: umkhiqizo oqediwe wokukhetha-amanzi okugeza-ungeza isixazululo esisizayo sokucwenga-ukomisa-irack ukupholisa-umuthi-ukuhlanza-ukupholisha-hot-dip ukuqeda ukupholisa
I-hot-dip galvanizing ithuthukiswa kusukela endleleni endala ye-hot-dip. Inomlando weminyaka eyi-140 kusukela iFrance yafaka uthayela oshisayo ediphini embonini ngo-1836. Kodwa-ke, imboni yokufaka amalahle ashisayo idiphu iye yathuthukiswa ngezinga elikhulu ngokuthuthuka okusheshayo kwensimbi egoqelwe ebandayo eminyakeni engama-30 edlule.
1. Imininingwane yomkhiqizo ikhethekile. Ugqinsi luyi-8-50mm, ububanzi buyi-150-625mm, ubude buyi-5-15m, futhi imininingwane yomkhiqizo iminyene, engahlangabezana nezidingo zabasebenzisi. Ingasetshenziswa esikhundleni sepuleti eliphakathi futhi ingafakwa ngokuqondile ngaphandle kokusika.
2. Ubuso bomkhiqizo bushelelezi futhi buhlanzekile. Inqubo yokunciphisa amanzi anengcindezi ephezulu isetshenziswa kabili kule nqubo ukuze kuqinisekiswe ukuthi ubuso bensimbi bushelelezi futhi buhlanzekile.
3. Izinhlangothi ziqondile futhi ama-chestnuts amanzi acacile. Ukugingqika kwesibili okuqondile ekugoqeni kokuqeda kuqinisekisa ukuma okuhle ezinhlangothini zombili, amakhona acacile, kanye nekhwalithi enhle yendawo ezinhlangothini.
4. Isikali somkhiqizo sinembile, umehluko wamaphuzu amathathu, umehluko wezinga elifanayo ungcono kunezinga lepuleti lensimbi; umkhiqizo uqondile futhi umumo wepuleti muhle. I-rolling yokuqeda ithatha inqubo eqhubekayo yokugoqa, isilawuli esizenzakalelayo se-looper, ukuqinisekisa ukuthi akukho nsimbi enqwabelene noma enwetshiwe, ukunemba kobukhulu bomkhiqizo kuphezulu, uhla lokubekezelelana, umehluko wamaphuzu amathathu, umehluko womugqa ofanayo, ukugoba kwesikela neminye imingcele kangcono kunepuleti eliphakathi nendawo, futhi umumo wepuleti uqondile. I-Degree yinhle. Ukugunda okubandayo, ukunemba okuphezulu kosayizi wobude.
5. Izinto zomkhiqizo zamukela izindinganiso zikazwelonke, ezifana namapuleti ensimbi. Ikhwalithi nezindinganiso zobuchwepheshe zihlelwa ngokuvumelana namazinga e-YB/T4212-2010 (Q345B/Q235B ibhekisela kumazinga e-GB/T1591-94 kanye ne-GB/T700-88 ngokulandelana).
1. Amandla aphezulu, isakhiwo sokukhanya: isakhiwo se-welding yegridi esiqinile sisenza sibe nezici zokuthwala okuphezulu, isakhiwo sokukhanya kanye nokuphakamisa kalula;
2. Ukubukeka okuhle nokuqina.

Inqubo yokukhiqiza insimbi eyisicaba eqondile Isimiso sokusebenza somshini wokuqedela insimbi eyisicaba ukusebenzisa amasethi amabili amasondo aleveliyo anyakazayo aye phezulu naphansi ukuya ezingeni langaphambili kanye nezinga lokugcina ekujikeni kokuqondisa koboya bensimbi obuyisicaba; sebenzisa ipheya yokuqedela okuhleliwe okuphambene Amasondo acindezelwa endaweni yobubanzi ukuze ububanzi bucindezelwe ukuze kuzuzwe imingcele elindelekile, futhi inani lokucindezela liyalungiseka; sebenzisa amasondo aqondile ayi-5 ukuze uqondise ububanzi. Lesi simiso sakhiwe ngokuyinhloko ibhokisi lokulawula, i-roller yokuqedela, iyunithi yokulinganisa ngaphambili, iyunithi yokuqedela, kanye neyunithi yokuqondisa.
Inqubo yokukhiqiza ingafinyezwa njengokuthi: ukulinganisa kwangaphambili → ukuqeda → ukuqondisa → ukuletha ileveli yangemuva. Insimbi eyisicaba/a/b iyinsimbi enobubanzi obungu-12-300mm, ukujiya okungu-4-60mm, isiphambano esingunxande kanye nemiphetho emsulwa kancane. Insimbi eyisicaba ingaba umkhiqizo wensimbi oqediwe, noma ingasetshenziswa njenge-billet yamapayipi ashiselwe kanye nama-slabs amancane amashidi apakishiwe. Uhlelo lokusebenza oluyinhloko: Insimbi eyisicaba ingasetshenziselwa ukwenza i-hoop iron, amathuluzi nezingxenye zemishini njengento eqediwe, futhi isetshenziswe njengesakhiwo sohlaka lokwakha kanye nezitebhisi ezizihambelayo ekwakhiweni. Insimbi eyisicaba ihlukaniswe yaba izinhlobo ezimbili ngokuya ngokuma kwayo: insimbi eyisicaba eyisicaba kanye ne-single-sided double groove spring flat steel. Insimbi eyisicaba ye-hot-rolled spring isetshenziswa ikakhulukazi ukwenza iziphethu zamaqabunga zezimoto, ogandaganda, ezokuthutha ngololiwe neminye imishini.
Indlela yenqubo ye-spring flat steel yemoto
Insimbi eyisicaba yasentwasahlobo yenziwa ngenqubo yokuncibilikisa i-converter. Uma kuqhathaniswa nobuchwepheshe obukhona, bunobuhle obulandelayo kanye nemiphumela emihle:
1. Ukuncibilika kwensimbi eyisicaba kusiguquli ikakhulukazi kusebenzisa insimbi encibilikisiwe njengempahla eluhlaza, enezici ezimbalwa eziyingozi kunsimbi encibilikisiwe, futhi ikhwalithi yensimbi eyisicaba ekhiqiziwe iqinisekisiwe.
2. Ngenxa yesivuno esikhulu kanye nokusetshenziswa kwamandla okuphansi, izindleko ngethani ngalinye ziphansi kunezithando zomlilo kagesi.
3. Insimbi encibilikisiwe iphonswa ngokuqondile ku-billets, eqeda inqubo yokukhokhisa futhi inciphise izindleko.
4. I-billet eqhubekayo yokusakaza inezinga eliphezulu lokusika-ubude, elingaqinisekisa izinga lokusika-ubude bensimbi eyisicaba futhi lihlangabezane nezidingo zabasebenzisi.
