Umehluko phakathi kwe-Hot Rolled Steel kanye ne-Cold Rolled Steel

1.Yini I-Hot Rolled Steel Material Grades
Insimbi iyingxube yensimbi equkethe inani elincane lekhabhoni. Imikhiqizo yensimbi iza ngamamaki ahlukene ngokusekelwe kumaphesenti ekhabhoni ayiqukethe. Amakilasi ensimbi ahlukene ahlukaniswa ngokuhambisana nekhabhoni yawo. Amamaki ensimbi egoqwe eshisayo ahlukaniswa ngamaqembu ekhabhoni alandelayo:
Ikhabhoni ephansi noma insimbi ethambile iqukethe u-0.3 % noma ngaphansi kwekhabhoni ngevolumu.
Insimbi enekhabhoni emaphakathi iqukethe i-0.3% kuya ku-0.6% yekhabhoni.
Izinsimbi ezinekhabhoni ephezulu zinekhabhoni engaphezu kuka-0.6%.
Izilinganiso ezincane zezinye izinto zokuhlanganisa ezifana ne-chromium, i-manganese noma i-tungsten nazo zengezwa ukuze kukhiqizwe amamaki ensimbi amaningi. Amamaki ensimbi ahlukene ahlinzeka ngezakhiwo ezimbalwa eziyingqayizivele njengamandla aqinile, i-ductility, i-malleability, ukuqina, kanye ne-thermal conductivity kagesi.

2.Umehluko phakathi kwe-Hot Rolled Steel kanye ne-Cold Rolled Steel
Imikhiqizo eminingi yensimbi yenziwa ngezindlela ezimbili eziyinhloko: ukugoqa okushisayo noma ukugoqa okubandayo. Insimbi egoqiwe eshisayo iyinqubo yokugaya lapho insimbi icindezelwa khona ezingeni lokushisa eliphezulu. Ngokuvamile, izinga lokushisa lensimbi egoqwe eshisayo lingaphezu kuka-1700°F. Insimbi egoqiwe ebandayo iyinqubo lapho insimbi icindezelwa khona ezingeni lokushisa elilingana negumbi.
Kubalulekile ukuqaphela ukuthi kokubili insimbi egoqiwe eshisayo nensimbi egoqiwe ebandayo akuzona amamaki ensimbi. Zingamasu okwenziwa ngaphambilini asetshenziselwa imikhiqizo ehlukahlukene yensimbi.
Inqubo Yensimbi Egoqiwe Eshisayo
Insimbi egoqiwe eshisayo ihlanganisa ukwenza kanye nokugingqa ama-slabs ensimbi abe umucu omude kuyilapho ishiswa ngaphezu kwezinga lokushisa elingcono kakhulu lokugoqa. I-red-hot slab idliswa ngochungechunge lwezigayo ukuze zakheke futhi zelule zibe umugqa omncane. Ngemva kokuqedwa kokwakhiwa, umucu wensimbi upholiswa ngamanzi bese ufakwa ikhoyili. Amazinga ahlukene okupholisa amanzi athuthukisa ezinye izici ze-metallurgical ensimbi.
Ukujwayela insimbi egoqiwe eshisayo ekamelweni lokushisa kuvumela amandla andayo kanye ne-ductility.
Insimbi egoqiwe eshisayo ivamise ukusetshenziselwa ukwakha, amathrekhi kaloliwe, insimbi yensimbi, nezinye izinhlelo zokusebenza ezingadingi ukuqedwa okukhangayo noma umumo onembile nokubekezelelwa.
Inqubo Yensimbi Egoqiwe Ebandayo
Insimbi egoqiwe ebandayo iyashisisa futhi ipholiswe njengensimbi egoqiwe eshisayo kodwa bese iphinde icutshungulwe kusetshenziswa i-annealing noma i-terer rolling ukuze kuthuthukiswe amandla aphezulu okubamba kanye namandla okukhiqiza. Umsebenzi owengeziwe kanye nesikhathi sokucutshungulwa kwengeza ezindlekweni kodwa kuvumela ukubekezelelana okuseduze futhi kunikeze izinhlobonhlobo zezinketho zokuqeda. Leli fomu lensimbi linomkhawulo oshelelayo futhi lisetshenziswa ezinhlelweni ezidinga isimo sendawo ethile kanye nokubekezelelana kobukhulu.
Ukusetshenziswa okuvamile kwensimbi egoqiwe ebandayo kuhlanganisa izingxenye zesakhiwo, ifenisha yensimbi, izinto zikagesi zasendlini, izingxenye zezimoto kanye nezicelo zobuchwepheshe lapho ukunemba noma ubuhle budingeka khona.

3.Hot Rolled Steel Amabanga
Insimbi egoqiwe eshisayo iyatholakala kumamaki ambalwa ukuze ihlangabezane nezicaciso zephrojekthi yakho. I-American Society for Testing and Materials (ASTM) noma i-Society of Automotive Engineers (SAE) ibeka amazinga namabanga ngokuya ngesakhiwo somzimba sensimbi ngayinye namandla.
Amabanga ensimbi ye-ASTM aqala ngohlamvu “A” olumele izinsimbi ezinensimbi. Isistimu yokugreda ye-SAE (eyaziwa nangokuthi i-American Iron and Steel Institute noma uhlelo lwe-AISI) isebenzisa inombolo enamadijithi amane ekuhlukaniseni. Amabanga ensimbi yensimbi engenalutho kulesi simiso aqala ngedijithi engu-10, alandelwe izinombolo ezimbili ezibonisa ukugxiliswa kwekhabhoni.
Okulandelayo amamaki avamile ensimbi egoqiwe eshisayo. Sicela uqaphele ukuthi eminye imikhiqizo inikezwa kukho kokubili okukhethwa kukho okugoqiwe okushisayo nokubandayo.

A36 Insimbi Eginqiwe Eshisayo
Insimbi egoqiwe eyi-A36 eshisayo ingenye yezinsimbi ezigoqiwe ezishisayo ezitholakalayo (futhi iza ngenguqulo egoqiwe ebandayo, engavamile kakhulu). Le carbon steel ephansi igcina ngaphansi kuka-0.3% we-carbon content ngesisindo, 1.03% manganese, 0.28% i-silicon, 0.2% yethusi, 0.04% phosphorus, kanye ne-0.05% sulphur. Izicelo ezijwayelekile zezimboni zensimbi ze-A36 zifaka:
Ozimele bamaloli
Imishini yezolimo
Ukubeka amashelufu
Ama-walkways, amarempu, nezinsimbi zonogada
Ukwesekwa kwesakhiwo

Ukwenziwa okuvamile

1018 Ibha Yensimbi Egingqiwe Yekhabhoni Eshisayo
Eduze kwe-A36, i-AISI/SAE 1018 ingelinye lamabanga ensimbi ajwayelekile. Ngokuvamile, leli banga lisetshenziselwa ukukhetha i-A36 kumafomu ebha noma ama-strip. Izinto zensimbi ezingu-1018 ziza kuzo zombili izinhlobo ezigoqiwe ezishisayo nezibandayo, nakuba okubandayo okugoqiwe kuvame ukusetshenziswa kakhulu. Zombili lezi zinguqulo zinamandla angcono nobulukhuni kune-A36 futhi zifaneleka kangcono ukusebenza okubandayo, njengokugoba noma ukunyakazisa. I-1018 iqukethe kuphela u-0.18% wekhabhoni kanye no-0.6-0.9% we-manganese, engaphansi kwe-A36. Futhi iqukethe imikhondo ye-phosphorus nesibabule kodwa ukungcola okumbalwa kune-A36.
Izicelo zensimbi ezijwayelekile ze-1018 zifaka:
Amagiya
Amaphini
Ama-Ratchets
Iziliphu zamathuluzi kawoyela
Izikhonkwane
Izikhonkwane zamaketanga
Amalayini
Izifundi
Izikhonkwane zehange

1011 Ishidi Lensimbi Eligoqiwe Elishisayo
1011 Ishidi lensimbi egoqiwe eshisayo nepuleti linikeza indawo eqinile kunensimbi egoqiwe ebandayo nepuleti. Uma ifakwe uthayela, isetshenziswa nasezintweni lapho kudingekile ukumelana nokugqwala. Amandla aphezulu kanye neshidi lensimbi le-HR elakheka kakhulu nepuleti kulula ukubhola, ukwakha nokushisela. Ishidi lensimbi egoqiwe eshisayo kanye nepuleti kuyatholakala njenge-P&O egoqiwe evamile noma i-hot rolled.
Ezinye zezinzuzo ezihlotshaniswa neshidi lensimbi eligoqiwe elingu-1011 kanye nepuleti zifaka ukukhuphuka kokonakala, izinga eliphezulu lokukhiqiza, kanye nokwehla uma kuqhathaniswa nokuginqika okubandayo. Izicelo zifaka:
Isakhiwo nokwakha
Ezezimoto nezokuthutha
Iziqukathi zokuthutha
Uphahla
Izinto zikagesi
Imishini esindayo

Hot Rolled ASTM A513 Steel
Ukucaciswa kwe-ASTM A513 okwamashubhu ensimbi agingqiwe e-carbon. Amashubhu ensimbi agingqiwe ashisayo akhiqizwa ngokudlula insimbi yeshidi elishisayo ngamarola ukuze afinyelele ubukhulu obuthile bomzimba. Umkhiqizo oqediwe unomkhawulo omaholoholo onamakhona ane-radiused kanye nokwakhiwa okushiselwe noma okungenamthungo. Ngenxa yalezi zici, ishubhu yensimbi egoqiwe eshisayo ifaneleka kangcono izinhlelo zokusebenza ezingadingi izimo eziqondile noma ukubekezelelana okuqinile.
Ishubhu lensimbi eligoqiwe elishisayo kulula ukusika, ukulishisela, ukwakha kanye nomshini. Isetshenziselwa izicelo eziningi zezimboni, kuhlanganise:
