1. Kuyambitsa mwachidule mbale wamba wozizira

Ndi chinthu chomwe chimapezedwa ndi kukanikiza kozizira kwa mapepala okulungidwa otentha. Chifukwa cha kuzizira kwamitundu yambiri, mawonekedwe ake apamwamba ndi abwino kuposa a pepala lotentha, ndipo pambuyo pa chithandizo cha kutentha, zinthu zabwino zamakina zimatha kupezeka.

1. Gulu la kugwiritsa ntchito mbale wamba ozizira ozizira

Malinga ndi zosowa zosiyanasiyana zamabizinesi opanga, mapepala oziziritsa ozizira nthawi zambiri amagawidwa kukhala:

Pepala lodzigudubuza lomwe nthawi zambiri limagwiritsidwa ntchito pozizira, pepala lopukutira lozizira, chojambula chakuya, chojambula chakuya komanso pepala lozizira kwambiri,

Nthawi zambiri amaperekedwa m'makoyilo ndi mapepala athyathyathya, makulidwe ake amawonetsedwa mamilimita,

M'lifupi ndi zambiri: 1000mm ndi 1250mm, ndi kutalika zambiri 2000mm ndi 2500mm.

2. Kalasi ya mbale wamba ozizira adagulung'undisa

Magiredi ofanana ndi awa:

Q195, Q215, Q235, 08AL, SPCC, SPCD, SPCE, SPCEN, ST12, ST13, ST14, ST15, ST16, DC01, DC03, DC04, DC05, DC06, etc.;

ST12:

Kuwonetsedwa ngati kalasi yodziwika bwino yachitsulo, zinthuzo ndizofanana ndi za Q195, SPCC, ndi magiredi a DC01;

ST13/14:

Gulu lachitsulo lomwe limawonetsedwa ngati kalasi yopondaponda ndilofanana ndi zinthu za 08AL, SPCD, DC03/04;

ST15/16:

Gulu lachitsulo lomwe limawonetsedwa ngati kalasi yopondaponda ndilofanana ndi zinthu za 08AL, SPCE, SPCEN, DC05/06.

3. Njira yofotokozera kalasi ndi kukula kwa mbale wamba zozizira

Mwachitsanzo, ST12 yopangidwa ndi Taishan Industrial Development Group Iron and Steel Co., Ltd., 1 * 1250 * 2500/C, yofotokozedwa ngati: kalasi ya ST12 yamba ozizira wamba, makulidwe ndi 1mm, m'lifupi ndi 1250mm, kutalika ndi 2500mm kapena C koyilo .

Maonekedwewo amapakidwa ndi khungu loyera lachitsulo, ndipo mawonekedwe amakina ndi omwe amapezeka kwambiri komanso oyambira zitsulo, zomwe zingagwiritsidwe ntchito kupindika ndi kupanga, osati kupondaponda. Amagwiritsidwa ntchito kuluma makina,

Mwachitsanzo, chipolopolo cha firiji, thanki mafuta a galimoto, etc.

Zogulitsa zomwe zili pamwamba pa ST13 zimagwiritsidwa ntchito m'mafakitale omwe amafunikira kujambula mozama, monga kupanga magalimoto, matanki amafuta a injini za dizilo, ndi zina zotero, zomwe munthu azigwiritsa ntchito zimadalira zojambula zakuya.

Kusiyana pakati pa ST12 ndi SPCC: Zomwe zimapangidwira pazinthu ziwirizi zimakhala zofanana, koma njira yobwezera ndiyosiyana. Zomwe zimakhala zolimba za ST12 ndizolimba kuposa za SPCC.

Japanese JIS muyezo zakuthupi tanthauzo

SPCC—S amatanthauza chitsulo (Chitsulo), P amatanthauza mbale (Mbale), C amatanthauza kuzizira (Yozizira), C amatanthauza zamalonda (Zamalonda), womwe ndi muyezo wa JIS waku Japan.

Ngati mukufuna kuwonetsetsa mphamvu zamakokedwe, onjezani T kumapeto kwa kalasi, yomwe ndi: SPCCT.

SPCD-imasonyeza pepala lozizira la carbon zitsulo ndi mzere wopondaponda, womwe ndi wofanana ndi chitsulo chapamwamba cha carbon 08AL (13237) cha China 08AL (13237).

SPCE—Imawonetsa pepala lachitsulo chozizira chozizira cha kaboni ndi chingwe chojambula mwakuya, chomwe ndi chofanana ndi chitsulo chakuya cha 08AL (5213) cha China.

Ngati kusasunga nthawi kukufunika, onjezani N kumapeto kwa giredi kuti mukhale SPCEN.

Pepala lachitsulo chozizira ndi chitsulo chozimitsa ndi kutenthetsa khodi: chikhalidwe chokhazikika ndi A, kuzimitsa kokhazikika ndi kutentha ndi S, 1/8 kuuma ndi 8, 1/4 kuuma ndi 4, 1/2 kuuma ndi 2, kuuma kwathunthu ndi 1. Khodi yokonza pamwamba: D ya kugudubuza komaliza, B kwa kumaliza kowala.

Mwachitsanzo, SPCC-SD imayimira pepala lozimitsidwa komanso lotenthedwa, lopiringizidwa ndi cholinga chozizira.

Chitsanzo china ndi SPCCT-SB, kutanthauza kuzimitsa ndi kutentha kwanthawi zonse, kukonza kowala, ndi mapepala a kaboni ozizira omwe amafunikira zida zotsimikizika zamakina.

Chitsanzo china ndi SPCC-1D, zomwe zikutanthauza kuti pepala lolimba la matt lozizira ndi chitsulo cha carbon.

Njira yofotokozera zitsulo zamakina opangira makina ndi: S + carbon content + code code (C, CK), pomwe mpweya wa carbon umayimiridwa ndi mtengo wapakati * 100, chilembo C chikuyimira carbon, ndipo chilembo K chikuyimira chitsulo cha carburizing. . Mwachitsanzo, koyilo ya carbon knot S20C ili ndi mpweya wa 0.18-0.23%.

China GB muyezo zakuthupi tanthauzo

Kwenikweni agawidwa mu:

Q195, Q215, Q235, Q255, Q275, ndi zina.

Q imayimira chilembo choyamba cha pinyin ya Chitchaina cha mawu akuti "Qu" pazitsulo zokolola, ndipo 195, 215, ndi zina zotero zimayimira mtengo wa zokolola.

Pankhani ya mankhwala, otsika carbon zitsulo makalasi:

Kukula kwa magiredi a Q195, Q215, Q235, Q255, ndi Q275, kumapangitsa kuti mpweya wa carbon ndi manganese ukhale wochuluka, komanso kukhazikika kwa pulasitiki.

2. Chidule chachidule cha pepala lachitsulo chovimbitsira moto (choyera siliva)

Iwo amapangidwa ndi otentha adagulung'undisa zitsulo Mzere kapena ozizira adagulung'undisa zitsulo Mzere monga gawo lapansi kudzera mosalekeza otentha-kuviika galvanizing ndondomeko, amene angalepheretse pamwamba zitsulo mbale woonda ndi zitsulo Mzere kuti dzimbiri ndi dzimbiri.

The otentha-kuviika kanasonkhezereka pepala amaperekedwa ngati amakona anayi lathyathyathya mbale ndi mtanda kudula; koyilo yovimbika yotentha imaperekedwa ngati mpukutu popiringa.

Chifukwa cha magawo osiyanasiyana omwe amagwiritsidwa ntchito, ma sheet achitsulo oviika otentha amatha kugawidwa kukhala ma coils otenthetsera opaka malata ndi ma coils otenthetsera otentha, omwe amagwiritsidwa ntchito kwambiri pomanga, zida zapanyumba, magalimoto, zotengera, zoyendera ndi mafakitale apakhomo. Makamaka zomangamanga zitsulo, kupanga magalimoto, kupanga zitsulo zenera ndi mafakitale ena.

1. Makhalidwe a otentha-kuviika kanasonkhezereka zitsulo pepala

Kukana kwamphamvu kwa dzimbiri, zabwino pamwamba, zabwino pokonza mwakuya, zachuma ndi zothandiza, etc.

2. Gulu ndi zizindikiro za kutentha-kuviika kanasonkhezereka zitsulo mapepala

Malinga ndi ntchito yokonza, imagawidwa kukhala: cholinga chachikulu (PT), mechanical interlocking (JY), kujambula kozama (SC), kukalamba kozama kwambiri (CS), ndi kapangidwe (JG);

Malingana ndi kulemera kwa nthaka wosanjikiza: pamwamba pa nthaka yoyera imagawidwa kukhala: 100/100 (kulemera kwa nthaka wosanjikiza ndi zosakwana 100g/m2),

120/120, 200/200, 275/275, 350/350, 450/450, 600/600;

Zinc-iron alloy pamwamba amagawidwa mu: 90/90

(Kulemera kwa nthaka-chitsulo aloyi wosanjikiza zosakwana 90g/m2), 100/100, 120/120, 180/180;

Malinga ndi mawonekedwe apamwamba, amagawidwa kukhala: spangle Z yachibadwa, kangapo kakang'ono X, sing'anga yosalala GZ, zinc-iron alloy XT;

Malingana ndi khalidwe lapamwamba, lagawidwa kukhala: Gulu I (I), Gulu II (II);

Malinga ndi kulondola kwa dimensional, imagawidwa kukhala: kulondola kwapamwamba A, kulondola wamba B;

Malinga ndi chithandizo chapamwamba, amagawidwa kukhala: chromic acid passivation L, oiling Y, chromic acid passivation kuphatikiza mafuta LY.

Chitsulo chovimbidwa chotentha cha Taishan Industrial Development Group:

Taishan Industrial Development Group Phase II galvanizing otentha-kuviika

Gawo lachiwiri la galvanizing yotentha ya Taishan Industrial Development Group imapangidwa ndi chitsulo chosasunthika chozizira kapena chotenthetsera pa Unit 2030, ndipo chimagwiritsidwa ntchito pazinthu zambiri kapena zomangamanga.

Kukula kopereka kwa gawo lachiwiri la kutentha kuviika galvanizing: makulidwe (0.3-0.3), m'lifupi (800-1830), kutalika (mbale 1000-6000, koyilo mkati mwake 610) mu mm.

Gawo lachiwiri la dip dip galvanizing limagawidwa molingana ndi kapangidwe kake: Z amatanthawuza spangle wamba, N amatanthauza zero spangle, X amatanthauza kapang'ono kakang'ono, ndipo G amatanthauza spangle yosalala.

Gawo lachiwiri la galvanizing yotentha-dip imagawidwa molingana ndi chithandizo chapamwamba: L amatanthauza chromic acid passivation, Y amatanthauza kuthira mafuta, LY amatanthauza chromic acid passivation + mafuta.
Makamaka kuchepetsa kapena kupewa dzimbiri loyera panthawi yoyendetsa kapena kusunga.
