1. Intshayelelo emfutshane yepleyiti eqhelekileyo eqengqelekayo
Iyimveliso efunyenwe ngokucinezela okubandayo kwamaphepha ashushu.Ngenxa ye-multi-pass cold rolling, umgangatho wayo ophezulu ungcono kunephepha elitshisayo, kwaye emva kokunyanga kokushisa, iimpawu ezintle zomatshini zingafumaneka.
1. Ukuhlelwa kokusetyenziswa kwamacwecwe aqhelekileyo abandayo
Ngokweemfuno ezahlukeneyo zamashishini emveliso, amaphepha aqengqelekayo abandayo ahlala ahlulwe abe:
Ngokuqhelekileyo kusetyenziswa iphepha eliqengqelekayo elibandayo, iphepha eliqengqelekayo elibandayo, umzobo onzulu, umzobo onzulu kakhulu kunye nephepha eliqengqelekayo elipholileyo,
Ngokuqhelekileyo zihanjiswa ngeekhoyili kunye namaphepha acwebileyo, ubukhulu bubonakaliswa ngeemilimitha,
Ububanzi ngokubanzi: 1000mm kunye 1250mm, kwaye ubude ngokubanzi 2000mm kunye 2500mm.
2. Ibakala lepleyiti eqhelekileyo eqengqelekayo ebandayo
Amanqaku aqhelekileyo ngala:
Q195, Q215, Q235, 08AL, SPCC, SPCD, SPCE, SPCEN, ST12, ST13, ST14, ST15, ST16, DC01, DC03, DC04, DC05, DC06, njl.;
ST12:
Ivakaliswe njengelona bakala liqhelekileyo lentsimbi, izinto eziphathekayo zifana nenqanaba le-Q195, SPCC, kunye ne-DC01;
ST13/14:
Ibakala lentsimbi elichazwe njengebakala lokunyathela ngokusisiseko liyafana nezinto ze-08AL, SPCD, DC03/04 grade;
ST15/16:
Ibakala lentsimbi elichazwe njengebakala lokunyathela ngokusisiseko liyafana nezinto ze-08AL, SPCE, SPCEN, DC05/06 grade.
3. Indlela yokubonakalisa ibakala kunye nobukhulu beepleyiti eziqhelekileyo eziqengqelekayo ezibandayo
Ngokomzekelo, i-ST12 eveliswe yi-Taishan Industrial Development Group Iron kunye ne-Steel Co., Ltd., 1 * 1250 * 2500 / C, ichazwe njenge: i-grade ST12 ipleyiti ebandayo eqhelekileyo, ubukhulu yi-1mm, ububanzi yi-1250mm, ubude yi-2500mm okanye i-C coil. .
Imbonakalo ipakishwe ngesikhumba esimhlophe sentsimbi, kwaye iimpawu zomatshini zezona ziqhelekileyo kunye namabakala ensimbi asisiseko, angasetyenziselwa ukugoba kunye nokwenza, kungekhona ukunyathela.Isetyenziselwa ukuluma ngoomatshini,
Ngokomzekelo, igobolondo yefriji, itanki yepetroli yesithuthi, njl.
Iimveliso ezingaphezulu kwe-ST13 zisetyenziswa kumashishini afuna umzobo onzulu, njengokwenziwa kweemoto, iitanki zamafutha eenjini zedizili, njl.
Umahluko phakathi kwe-ST12 kunye ne-SPCC: Iimpawu zomatshini zeemveliso ezimbini ziphantse zifane, kodwa indlela yokubuyisela yahlukile.Iimpawu zokuqina zezinto ze-ST12 zomelele kune-SPCC.
Japanese JIS intsingiselo impahla eqhelekileyo
I-SPCC-S ithetha intsimbi (iNsimbi), i-P ithetha ipleyiti (iPlate), i-C ithetha ukubanda (iBanda), i-C ithetha urhwebo (uRhwebo), oluyimigangatho ye-JIS yaseJapan.
Ukuba ufuna ukuqinisekisa amandla e-tensile, yongeza u-T ekupheleni kwebakala, oko kukuthi: SPCCT.
I-SPCD-ibonisa i-carbon steel sheet epholileyo kunye ne-strip ye-stamping, elingana ne-China ye-08AL (13237) ephezulu ye-carbon structural steel steel.
I-SPCE-Ibonisa i-carbon steel sheet epholileyo kunye nomcu wokuzoba nzulu, olingana ne-China's 08AL (5213) yentsimbi enzulu yokudweba.
Ukuba ukungabikho kwexesha kuyadingeka, yongeza u-N ekupheleni kwebakala ukuze ube yi-SPCEN.
Icwecwe lentsimbi yekhabhoni epholileyo kunye nentsimbi yokucima kunye nekhowudi yokucima: i-annealed state yi-A, ukucima okusemgangathweni kunye nokuvutha ngu-S, 1/8 ukuqina ngu-8, 1/4 ukuqina ngu-4, 1/2 ukuqina ngu-2, ubunzima obupheleleyo 1. Ikhowudi yokusetyenzwa komphezulu: D yokuqengqeleka kokugqiba, B kukugqiba okuqaqambileyo.
Umzekelo, i-SPCC-SD imele umgangatho ocinyiweyo kwaye onomsindo, ogqityiweyo ogqityiweyo owenziwe ngokubanzi-injongo ebandayo ye-carbon sheet.
Omnye umzekelo yi-SPCCT-SB, oku kuthetha ukucima okusemgangathweni kunye nokufudumeza, ukusetyenzwa okuqaqambileyo, kunye namaphepha ekhabhoni aqengqiwe abandayo afuna iimpawu zoomatshini eziqinisekisiweyo.
Omnye umzekelo yi-SPCC-1D, oku kuthetha ukuba i-hard matt igqibezela i-carbon steel sheet ebandayo.
Indlela yokubonakalisa amabakala ensimbi yezakhiwo zoomatshini yile: S + umxholo wekhabhoni + ikhowudi yeleta (C, CK), apho umxholo wekhabhoni umelwe ngexabiso eliphakathi * 100, ileta C imele ikhabhoni, kwaye ileta K imele intsimbi ye-carburizing. .Ngokomzekelo, i-carbon knot coil S20C inomxholo wekhabhoni we-0.18-0.23%.
China GB intsingiselo impahla esemgangathweni
Yahlulwe ngokwesiseko:
Q195, Q215, Q235, Q255, Q275, njl.
I-Q imele ileta yokuqala ye-pinyin yaseTshayina yegama elithi "Qu" kwindawo yokuvunwa yentsimbi, kunye ne-195, i-215, njl. imele ixabiso lexabiso lesivuno.
Ngokumalunga nokwakheka kweekhemikhali, amanqanaba entsimbi ephantsi kwekhabhoni:
Amabakala amakhulu e-Q195, i-Q215, i-Q235, i-Q255, kunye ne-Q275, i-carbon content kunye nomxholo we-manganese, kwaye uzinzile ngakumbi iplastiki.
2. Intshayelelo emfutshane yentsimbi eshushu-diphu (isilivere emhlophe)
Iveliswa ngentsimbi eshushu-eqengqelekayo okanye intsimbi epholileyo eqengqelekayo njenge-substrate ngenkqubo eqhubekayo yokufaka i-galvanizing eshushu-dip, enokuthintela umphezulu wepleyiti yentsimbi ebhityileyo kunye nomtya wentsimbi ekudlekeni kunye nomhlwa.
Ishiti elishushu lokuntywila linikezelwe njengepleyiti ecaba yoxande ngokunqunyulwa kwe-cross-cutting;i-hot-dip galvanized coil inikezelwa njengomqulu ngokujija.
Ngenxa yamacandelo ahlukeneyo asetyenzisiweyo, amashiti esinyithi ashushu-diphu anokohlulwa abe ngamacangci ashushu aqengqelekayo kunye neekhoyili zamaphepha ashushu aqengqiwe ashushu-diphu, asetyenziswa ikakhulu kulwakhiwo, izixhobo zasekhaya, iimoto, izikhongozeli, ezothutho kunye amashishini asekhaya.Ingakumbi ulwakhiwo lwesakhiwo sentsimbi, ukwenziwa kweemoto, ukwenziwa kweefestile zentsimbi kunye namanye amashishini.
1. Iimpawu ze-hot-dip galvanized sheet sheet
Ukuxhathisa okuqinileyo kwe-corrosion, umgangatho olungileyo womphezulu, ulungele ukusetyenzwa okunzulu, uqoqosho kunye nokusebenza, njl.
2. Ukuhlelwa kunye neempawu zentsimbi eshushu-dip galvanized steel sheets
Ngokutsho kokusebenza kokusebenza, ihlukaniswe: injongo ngokubanzi (PT), i-mechanical interlocking (JY), umzobo onzulu (SC), ukuguga komzobo onzulu (CS), kunye nesakhiwo (JG);
Ngokobunzima be-zinc layer: ubuso be-zinc ecocekileyo buhlukaniswe: 100/100 (ubunzima be-zinc layer bungaphantsi kwe-100g / m2),
120/120, 200/200, 275/275, 350/350, 450/450, 600/600;
I-Zinc-iron alloy surface yahlulwe ibe yi: 90/90
(Ubunzima be-zinc-iron alloy layer ingaphantsi kwe-90g / m2), 100/100, 120/120, 180/180;
Ngokwesakhiwo somphezulu, ihlukaniswe ibe: i-spangle eqhelekileyo ye-Z, i-spangle encinci i-X, i-spangle egudileyo ye-GZ, i-zinc-iron alloy XT;
Ngokomgangatho womphezulu, uhlukaniswe: Iqela I (I), iQela II (II);
Ngokuchaneka komgangatho, yahlulahlulwe yaba: ukuchaneka okuphezulu A, ukuchaneka okuqhelekileyo B;
Ngokonyango olungaphezulu, lwahlulwe lwaba: chromic acid passivation L, oiling Y, chromic acid passivation plus oiling LY.
Ishiti lentsimbi eshushu yokudipha yeQela loPhuhliso lweShishini laseTaishan:
IQela loPhuhliso loShishino lwaseTaishan iSigaba sesi-II sokugalela amanzi ashushu
Isigaba sesibini se-hot-dip galvanizing yeQela loPhuhliso lwezoShishino lwe-Taishan iveliswa ngokuqhubekayo kwe-galvanizing yentsimbi epholileyo okanye eshushu-eshushu kwi-Unit 2030, kwaye isetyenziselwa iinjongo eziqhelekileyo okanye iinjongo zesakhiwo.
Ububanzi bonikezelo lwesigaba sesibini sokutshisa-dip galvanizing: ubukhulu (0.3-0.3), ububanzi (800-1830), ubude (ipleyiti 1000-6000, coil yangaphakathi ububanzi 610) 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.
Isigaba sesibini se-hot-dip galvanizing sahlulwe ngokonyango lwangaphandle: L ithetha i-chromic acid passivation, i-Y ithetha i-oiling, i-LY ithetha i-chromic acid passivation + oiling.
Ikakhulu ukunciphisa okanye ukuphepha umhlwa omhlophe ngexesha lokuthutha okanye ukugcinwa.
