1. Ukwethulwa kafushane kwepuleti eligoqiwe elibandayo
Kungumkhiqizo otholwe ngokucindezela okubandayo kwamashidi agoqwe ashisayo. Ngenxa ye-multi-pass cold rolling, ikhwalithi yayo ephezulu ingcono kuneshidi elishisayo, futhi ngemva kokwelashwa kokushisa, izakhiwo ezinhle zemishini zingatholakala.
1. Ukuhlukaniswa kokusetshenziswa kwamapuleti ajwayelekile abandayo
Ngokuya ngezidingo ezihlukene zamabhizinisi okukhiqiza, amashidi agoqwe abandayo avame ukuhlukaniswa abe:
Ngokuvamile kusetshenziswa ishidi eligoqekayo elibandayo, ishidi eligoqekayo elibandayo, umdwebo ojulile, umdwebo ojule kakhulu kanye neshidi eligoqekayo elijule kakhulu,
Imvamisa ilethwa ngamakhoyili nangamashidi ayisicaba, ubukhulu buvezwa ngamamilimitha,
Ububanzi ngokuvamile: 1000mm kanye 1250mm, futhi ubude ngokuvamile 2000mm kanye 2500mm.
2. Ibanga lepuleti eligoqiwe elibandayo elijwayelekile
Amabanga ajwayelekile yilawa:
Q195, Q215, Q235, 08AL, SPCC, SPCD, SPCE, SPCEN, ST12, ST13, ST14, ST15, ST16, DC01, DC03, DC04, DC05, DC06, njll.;
ST12:
Ivezwa njengebanga lensimbi elivame kakhulu, impahla ngokuyisisekelo iyafana naleyo yamabanga e-Q195, SPCC, kanye ne-DC01;
ST13/14:
Ibanga lensimbi elivezwa njengebanga lokunyathela ngokuyisisekelo liyafana nempahla yamabanga 08AL, SPCD, DC03/04;
ST15/16:
Ibanga lensimbi elivezwa njengebanga lokugxiviza ngokuyisisekelo liyafana nempahla yamabanga 08AL, SPCE, SPCEN, DC05/06.
3. Indlela yokuveza izinga kanye nosayizi wamapuleti ajwayelekile agoqelwe ngokubanda
Isibonelo, i-ST12 ekhiqizwe yi-Taishan Industrial Development Group Iron and Steel Co., Ltd., 1*1250*2500/C, ichazwa ngokuthi: ipuleti elibandayo elivamile le-ST12, ugqinsi luyi-1mm, ububanzi buyi-1250mm, ubude buyi-2500mm noma ikhoyili engu-C. .
Ukubukeka kuhlanganiswe nesikhumba sensimbi esimhlophe, futhi izici zemishini zingamamaki ensimbi ajwayelekile futhi ayisisekelo, angasetshenziswa kuphela ukugoba nokwakheka, hhayi ukugxiviza. Isetshenziselwa ukulunywa ngomshini,
Isibonelo, igobolondo lesiqandisi, ithangi likaphethiloli lemoto, njll.
Imikhiqizo engaphezulu kwe-ST13 isetshenziswa ezimbonini ezidinga ukudweba okujulile, njengokukhiqiza izimoto, amathangi kaphethiloli ezinjini zikadizili, njll., okumele umuntu ayisebenzise kuncike ezidingweni ezijulile zokudweba.
Umehluko phakathi kwe-ST12 ne-SPCC: Izakhiwo zemishini zemikhiqizo emibili zicishe zifane, kodwa indlela yokubuyisela ihlukile. Izakhiwo eziqinile zezinto ze-ST12 zinamandla uma kuqhathaniswa nalezo ze-SPCC.
Japanese JIS incazelo impahla ejwayelekile
I-SPCC—S isho insimbi (Insimbi), u-P isho ipuleti (Ipuleti), u-C usho ukubanda (Okubanda), u-C usho ukuthi ezentengiselwano (Ezohwebo), okuyizinga lesiJapane le-JIS.
Uma udinga ukuqinisekisa amandla okuqina, engeza u-T ekupheleni kwebanga, okungukuthi: SPCCT.
I-SPCD—ibonisa ishidi lensimbi egoqelwe ebandayo kanye nomugqa wokugxiviza, okulingana nensimbi yekhwalithi ephezulu yekhabhoni engu-08AL (13237) yaseChina.
I-SPCE—Ibonisa ishidi lensimbi yensimbi egoqelwe ebandayo kanye nomucu wokudweba okujulile, okulingana nensimbi yokudweba ejulile yase-China engu-08AL (5213).
Uma isidingo sokungagcini isikhathi, engeza okuthi N ekupheleni kwebanga ukuze ube SPCEN.
Ishidi lensimbi yensimbi egoqelwe ebandayo kanye nekhodi yensimbi yokucisha kanye nekhodi yokushisa: isimo se-annealed ngu-A, ukucisha okujwayelekile kanye nokushisa kungu-S, ukuqina okungu-1/8 kungu-8, 1/4 ubulukhuni 4, 1/2 ubulukhuni 2, ubulukhuni obugcwele 1. Ikhodi yokucutshungulwa kwendawo: D yokugingqika okubuthuntu kokuqedwa, B kokugingqika kokuqedwa okugqamile.
Isibonelo, i-SPCC-SD imele ishidi lekhabhoni elicishiwe neliqinile, eliqediwe elinenhloso evamile eligoqelwe ngokubanda.
Esinye isibonelo i-SPCCT-SB, okusho ukucisha nokushisa okujwayelekile, ukucutshungulwa okukhanyayo, namashidi ekhabhoni agingqiwe abandayo adinga izakhiwo eziqinisekisiwe zokusilungisa.
Esinye isibonelo i-SPCC-1D, okusho ukuthi ishidi lensimbi yensimbi ye-matt eqinile.
Indlela yokuveza amamaki ensimbi ezakhiwo zemishini yile: S + okuqukethwe kwekhabhoni + ikhodi yezinhlamvu (C, CK), lapho okuqukethwe kwekhabhoni kuvezwa inani eliphakathi nendawo * 100, uhlamvu C lumele ikhabhoni, futhi uhlamvu K lumele insimbi evuthayo. . Isibonelo, ikhoyili ye-carbon knot S20C inokuqukethwe kwekhabhoni okungu-0.18-0.23%.
Incazelo yezinto ezibonakalayo zaseChina GB
Ngokuyisisekelo ihlukaniswe yaba:
Q195, Q215, Q235, Q255, Q275, njll.
U-Q umele uhlamvu lokuqala lwe-pinyin yesiShayina lwegama elithi "Qu" endaweni yokukhiqiza yensimbi, futhi u-195, 215, njll. umele inani lephoyinti lokukhiqiza.
Mayelana nokwakheka kwamakhemikhali, amamaki ensimbi e-carbon aphansi:
Uma amabanga e-Q195, i-Q215, i-Q235, i-Q255, ne-Q275 eba makhulu, ayanda okuqukethwe kwekhabhoni nokuqukethwe kwe-manganese, kanye nokusimama kwepulasitiki.
2. Ukwethulwa kafushane kweshidi lensimbi elidiphu elishisayo (elimhlophe elisiliva)
Ikhiqizwa ngomugqa wensimbi ogoqeke oshisayo noma umucu wensimbi ogoqeke ngokubanda njengengxenye engaphansi ngenqubo eqhubekayo yokufaka uthayela wediphu eshisayo, engavimbela ingaphezulu lepuleti lensimbi elincanyana kanye nensimbi ekugqwaleni nasekugqwaleni.
Ishidi elinothayela lokucwilisa elishisayo lihlinzekwa njengepuleti eliyisicaba elingunxande ngokusika ngokuphambana; ikhoyili yediphu eshisayo inikezwa njengomqulu ngokugoqa.
Ngenxa yokusetshenziswa kwama-substrates ahlukene, amashidi ensimbi afakwa uthayela ashisayo angahlukaniswa abe amakhoyili eshidi likathayela agoqelwe ashisayo kanye namakhoyili eshidi agoqelwe abandayo, asetshenziswa kakhulu ekwakheni, ezintweni zikagesi zasendlini, ezimotweni, ezitsheni, ezokuthutha kanye nasezintweni zokuhamba. izimboni zasekhaya. Ikakhulukazi ukwakhiwa kwesakhiwo sensimbi, ukukhiqiza izimoto, ukukhiqiza amawindi ensimbi nezinye izimboni.
1. Izici zeshidi lensimbi elishisayo-diphu
Ukumelana nokugqwala okuqinile, ikhwalithi enhle yendawo, ilungele ukucutshungulwa okujulile, ukonga nokusebenziseka, njll.
2. Ukuhlelwa kanye nezimpawu zamashidi ensimbi ashisayo adiphu
Ngokusho kokucubungula ukusebenza, ihlukaniswe: inhloso evamile (PT), ukuxhumanisa ngomshini (JY), ukudweba okujulile (SC), ukuguga okujulile kokudweba (CS), kanye nesakhiwo (JG);
Ngokwesisindo sengqimba ye-zinc: ubuso be-zinc ehlanzekile buhlukaniswe: 100/100 (isisindo se-zinc layer singaphansi kuka-100g/m2),
120/120, 200/200, 275/275, 350/350, 450/450, 600/600;
I-Zinc-iron alloy surface ihlukaniswe yaba: 90/90
(Isisindo se-zinc-iron alloy layer singaphansi kuka-90g/m2), 100/100, 120/120, 180/180;
Ngokusho kwesakhiwo esingaphezulu, ihlukaniswe ngokuthi: i-spangle Z evamile, i-spangle X encane, i-spangle ebushelelezi ye-GZ, i-zinc-iron alloy XT;
Ngokwekhwalithi ephezulu, ihlukaniswe yaba: Iqembu I (I), Iqembu II (II);
Ngokusho kokunemba kobukhulu, ihlukaniswe yaba: ukunemba okuthuthukisiwe A, ukunemba okuvamile B;
Ngokusho kokwelashwa okungaphezulu, ihlukaniswe ngokuthi: chromic acid passivation L, oiling Y, chromic acid passivation plus oiling LY.
Ishidi lensimbi elicwebezelayo elishisayo le-Taishan Industrial Development Group:
I-Taishan Industrial Development Group Phase II yokufaka ugesi oshisayo
Isigaba sesibili se-hot-dip galvanizing se-Taishan Industrial Development Group sikhiqizwa ngokufaka uthayela okuqhubekayo kwensimbi egoqelwe ebandayo noma egoqwe ngokushisayo ku-Unit 2030, futhi isetshenziselwa izinhloso ezijwayelekile noma izinjongo zesakhiwo.
Ububanzi bokunikezwa kwesigaba sesibili se-hot-dip galvanizing: ukujiya (0.3-0.3), ububanzi (800-1830), ubude (ipuleti 1000-6000, ikhoyili ububanzi bangaphakathi 610) ngamamilimitha.
Isigaba sesibili sokucwebezelisa idiphu eshisayo ihlukaniswe ngokwesakhiwo esingaphezulu: u-Z usho i-spangle esivamile, u-N usho i-spangle esiyiziro, u-X usho i-spangle esincane, kanti u-G usho i-spangle esibushelelezi.
Isigaba sesibili se-hot-dip galvanizing sihlukaniswa ngokokwelashwa kwendawo: L isho i-chromic acid passivation, Y isho ukugcoba, i-LY isho i-chromic acid passivation + oiling
Ikakhulukazi ukunciphisa noma ukugwema ukugqwala okumhlophe ngesikhathi sokuthutha noma ukugcinwa.
