1. Ukuqaliswa kwephepha eliqhelekileyo elipholileyo liyimveliso efunyenwe kwiphepha elishushu elifakwe kwi-cold pressure processing.
Ngenxa ye-multi-pass cold rolling, umgangatho ophezulu ungcono kunephepha elitshisayo, kwaye iimpawu ezintle zoomatshini zingafumaneka emva kokunyanga ukushisa.
1. Ukuhlelwa kokusetyenziswa kwamaphepha aqhelekileyo aqengqwayo abandayo Ngokweemfuno ezahlukeneyo zabavelisi, amaphepha aqengqeleki- leyo ahlala ehlulwe abe ngawa: amaphepha aqengqeleki- leyo abandayo, amashiti aqengqeleki- leyo, aqengqeleki- leyo, umzobo onzulu, unzulu-nzulu. umzobo kunye ne-ultra-deep-deep-drawing cold-rolled sheets , Ngokuqhelekileyo zihanjiswa ngeekhoyili kunye namaphepha acwebileyo, ubukhulu bubonakaliswe ngeemilimitha, ububanzi ngokuqhelekileyo buyi-1000mm kunye ne-1250mm, kwaye ubude ngokubanzi yi-2000mm kunye ne-2500mm.
2. Amanqaku aqhelekileyo aqengqelekayo apholileyo ngala: Q195, Q215, Q235, 08AL, SPCC, SPCD, SPCE, SPCEN, ST12, ST13, ST14, ST15, ST16, DC01, DC03, DC04, DC05, DC06, njl. .;I-ST12 : ibonisa ibakala lensimbi eqhelekileyo, eyona nto ifana ne-Q195, i-SPCC, i-DC01 amabakala;I-ST13/14: ibonisa ibakala lensimbi ye-stamping, eyona nto ifana ne-08AL, i-SPCD, i-DC03/04 amabakala;I-ST15 / 16: ibonisa ukuba yintsimbi ye-stamping grade, ngokusisiseko ifana ne-08AL, i-SPCE, i-SPCEN, i-DC05/06 amabakala.
3. Indlela yokubonisa ubungakanani bebakala lephepha eliqhelekileyo elibandayo, elifana ne-ST12 eliveliswe ngu-Anshan Iron kunye neNsimbi, 1*1250*2500/C, licaciswe ngolu hlobo: ibakala ST12 ishidi elibandayo eliqhelekileyo, ubukhulu be-1mm, ububanzi 1250mm, ubude. 2500mm okanye C coil.Ukubonakala kuhlanganiswe ngokucokisekileyo kwintsimbi emhlophe, kwaye iimpawu zomatshini zezona ziqhelekileyo kunye neziseko zentsimbi ezisisiseko, ezingasetyenziselwa ukugoba kunye nokwenza, kungekhona ukunyathela.Isetyenziselwa ukulunywa ngoomatshini, njengamaqokobhe efriji, iitanki zamafutha emoto, njl. njl iimfuno ezinzulu zokudweba.
Umahluko phakathi kwe-ST12 kunye ne-SPCC: Iimpawu zomatshini zeemveliso zimbini ziphantse zafana, kodwa indlela yokufunxa yahlukile.Iipropathi eziqinileyo ze-ST12 zomelele kuneSPCC.Isixhobo esiqhelekileyo saseJapan se-JIS sithetha i-SPCC—S ithetha intsimbi (iNsimbi), i-P ithetha ipleyiti (iPlate), iC ithetha ukubanda (Ebandayo), iC ithetha ukurhweba (Yorhwebo), kumgangatho we-JIS waseJapan.Ukuqinisekisa amandla okuqina, yongeza u-T ekupheleni kwebanga: SPCCT.I-SPCD-imele i-carbon steel sheet epholileyo kunye ne-strip ye-stamping, elingana ne-China 08AL (13237) yensimbi ephezulu ye-carbon structural steel.I-SPCE-imele i-carbon steel sheet epholileyo kunye ne-strip yokudweba okunzulu, okulingana ne-China 08AL (5213) insimbi enzulu yokudweba.Ukuqinisekisa ukungabikho kwexesha, yongeza i-N ekupheleni kwebakala ibe yi-SPCEN.Icwecwe lentsimbi yekhabhoni epholileyo kunye nekhowudi yokucima kunye nekhowudi yokucima: i-annealing state yi-A, ukucima okusemgangathweni kunye nokutshisa yi-S, i-1/8 yobunzima yi-8, i-1/4 yobunzima yi-4, i-1/2 ubulukhuni yi-2, kunye nobunzima obupheleleyo 1. Ikhowudi yokusetyenzwa komphezulu: ukuqengqeleka kokugqiba okubuthuntu ngu-D, ukugqibezela okuqaqambileyo okuqengqelekayo yi-B. Umzekelo, i-SPCC-SD imele injongo eqhelekileyo epholileyo eqengqelekayo ikhabhoni sheet kunye nokucinywa okusemgangathweni kunye nokufudumeza kunye nokuqengqeleka kwe-matte.Omnye umzekelo yi-SPCCT-SB, oku kuthetha ukucima okusemgangathweni kunye nokufudumeza, ukusetyenzwa okuqaqambileyo, kunye neshiti lekhabhoni elibandayo elifuna iipropati eziqinisekisiweyo zoomatshini.Omnye umzekelo yi-SPCC-1D, emele i-hard matte egalelwe i-carbon steel sheet.
Indlela yokumela ibakala lensimbi yesakhiwo somatshini yile: S + i-carbon content + ikhowudi yeleta (C, CK), apho umxholo wekhabhoni ubonakaliswa ngexabiso eliphakathi * 100, ileta C imele ikhabhoni, kunye neleta K imele intsimbi. yokungcwaba.Njenge-carbon knot coil S20C, umxholo wayo wekhabhoni ngu-0.18-0.23%.Intsingiselo yezinto eziqhelekileyo zaseTshayina ze-GB zihlukaniswe ngokusisiseko zibe: Q195, Q215, Q235, Q255, Q275 njalo njalo.I-Q imele ileta yokuqala ye-pinyin yesiTshayina yegama elithi "Qu" kwinqaku lemveliso yentsimbi, kunye ne-195, i-215, njl. imele ixabiso lenqaku lesivuno.Ngokumalunga nokubunjwa kweekhemikhali, amabakala ensimbi ephantsi kwekhabhoni: Q195, Q215, Q235, Q255, Q275 Ukuphakama kwekhabhoni kunye nomxholo we-manganese, iplastiki yayo izinzile.
2. Ukuqaliswa kwe-hot-dip galvanized sheet sheet (isilivere emhlophe) iveliswa yinkqubo eqhubekayo ye-hot-dip galvanizing kunye nentsimbi eshushu edibeneyo okanye i-strip yensimbi epholileyo njenge-substrate, enokuthintela umphezulu weplate yentsimbi kunye nentsimbi. khulula ekudlekeni nasekuruseni.Amaphepha e-galvanized e-hot-dip anikezelwa kwiipleyiti ezisicaba ezixande emva kokunqunyulwa kwe-cross-cutting;Iikhoyili ezinezinki ezishushu-diphu zinikezelwa kwiikhoyili emva kokubhijela.Ngenxa substrates ezahlukeneyo ezisetyenzisiweyo, hot-dip amakhati sheet intsimbi zinokwahlulwa zibe ngamaphepha ashushu aqengqelekayo kunye neekhoyili kunye abandayo-waqengqelekela ashushu-dip amashiti kunye coils, ezisetyenziswa ikakhulu kulwakhiwo, izixhobo zasekhaya, iimoto, izitya, ezothutho kunye namashishini asekhaya.Ngokukodwa kulwakhiwo lwentsimbi, ukwenziwa kweemoto, ukwenziwa kweefestile zentsimbi kunye namanye amashishini.
1. Iimpawu zeshiti lensimbi eshushu-dip linamandla okumelana ne-corrosion, umgangatho omhle womphezulu, ulungele ukulungiswa okunzulu, uqoqosho kunye nokusebenza, njl.
2. Ukuhlelwa kunye neesimboli zentsimbi eshushu-diphu yahlulwe yaba: injongo jikelele (PT), mechanical engagement (JY), deep drawing (SC), super deep deep drawing aging (CS), structure (JG) ngokwe ukusetyenzwa komsebenzi;Ubunzima buhlulwe: ubuso be-zinc obucocekileyo buhlulwe: 100/100 (i-zinc layer ubunzima bungaphantsi kwe-100g/m2), 120/120, 200/200, 275/275, 350/350, 450/450, 600/600 ;i-zinc-iron alloy surface Yahlula-hlulwa ibe yi-90/90 (ubunzima be-zinc-iron alloy layer ingaphantsi kwe-90g/m2), 100/100, 120/120, 180/180;ngokwesakhiwo sobuso: i-spangle eqhelekileyo Z, i-spangle encinci i-X, i-smooth spangle GZ, i-Zinc-iron alloy XT;Ngokomgangatho womphezulu, uhlukaniswe ube: Iqela (I), iqela le-II (II);Ngokuchaneka komda, yahlulwe yaba: ukuchaneka okuphezulu A, ukuchaneka okuqhelekileyo B;Ngokonyango olungaphezulu, lwahlulwe lwaba: i-chromic acid passivation L, i-oyile yokugquma i-Y, i-chromic acid passivation kunye ne-oyile LY.
I-Baosteel hot-dip galvanized steel sheet: I-Baosteel Phase II I-Hot-dip Galvanizing I-Baosteel's Phase II I-hot-dip galvanizing iveliswa ngokudipha ngokuqhubekayo igalvanizing ye-tandem ebandayo okanye i-tandem eshushu esongiweyo kwiyunithi ka-2030 ngenjongo eqhelekileyo okanye ukusetyenziswa kolwakhiwo.
Ububanzi bonikezelo lwesigaba sesibini sokutshisa-dip galvanizing: ubukhulu (0.3-0.3) ububanzi (800-1830) ubude (ipleyiti 1000-6000, ikhoyili yangaphakathi ububanzi 610) unit mm.
Inqanaba lesibini le-hot-dip galvanizing lahlulwe ngokwesakhiwo somphezulu: u-Z uthetha ispangle esiqhelekileyo, u-N uthetha i-spangle enguziro, u-X uthetha i-spangle encinci, kwaye u-G uthetha i-spangle egudileyo.
Inqanaba lesibini i-hot-dip galvanizing yahlulwe ngokonyango lomphezulu: L ithetha i-chromic acid passivation, i-Y ithetha i-oiling, i-LY ithetha i-chromic acid passivation + i-oiling ikakhulu ukunciphisa okanye ukuphepha umhlwa omhlophe ngexesha lokuthutha okanye ukugcinwa.
