1. Sumo pfupi yendiro yakajairwa inotonhora
Icho chigadzirwa chinowanikwa nekutsikirira kunotonhora kwemashizha anopisa.Nekuda kweiyo yakawanda-inopfuura inotonhora rolling, iyo yepamusoro yemhando iri nani pane iyo inopisa-yakatenderedzwa pepa, uye mushure mekupisa kurapwa, yakanaka mechanical properties inogona kuwanikwa.
1. Kurongeka kwekushandiswa kwemahwendefa akajairwa anotonhora
Zvinoenderana nezvinodiwa zvakasiyana zvemabhizinesi ekugadzira, mashizha anotonhora-akatenderedzwa anowanzo kukamurwa kuita:
Inowanzo shandiswa inotonhora-yakatenderedzwa pepa, kutsika-giredhi inotonhora-yakakungurutswa pepa, yakadzika-kudhirowa, yakawedzera-yakadzika-kudhirowa uye yekupedzisira-yakadzika-kudhirowa-giredhi inotonhora-yakakungurutswa pepa,
Kazhinji inounzwa mumakoiri uye mashizha akatsetseka, ukobvu hunoratidzwa mumamirimita,
Iyo yakafara kazhinji: 1000mm uye 1250mm, uye kureba kazhinji 2000mm uye 2500mm.
2. Giredhi rendiro yakajairika inotonhora-yakakungurutswa
Magiredhi akajairika ndeaya:
Q195, Q215, Q235, 08AL, SPCC, SPCD, SPCE, SPCEN, ST12, ST13, ST14, ST15, ST16, DC01, DC03, DC04, DC05, DC06, nezvimwewo;
ST12:
Inoratidzwa segiredhi resimbi rinonyanya kuzivikanwa, zvinhu zvacho zvakangofanana neicho cheQ195, SPCC, uye DC01 mamakisi;
ST13/14:
Giredhi resimbi rinoratidzwa segiredhi rekutsikisa rakanyanya kufanana nezvinhu zve08AL, SPCD, DC03/04 mamakisi;
ST15/16:
Giredhi resimbi rinoratidzwa segiredhi rekutsika rakanyanya kufanana nezvinhu zve08AL, SPCE, SPCEN, DC05/06 mamakisi.
3. Nzira yekuratidza giredhi uye saizi yeakajairika mahwendefa akakungurutswa
Semuenzaniso, ST12 inogadzirwa neTaishan Industrial Development Group Iron uye Steel Co., Ltd., 1 * 1250 * 2500 / C, inoratidzwa se: giredhi ST12 yakajairika ndiro inotonhora, ukobvu i1mm, hupamhi 1250mm, kureba 2500mm kana C coil. .
Chitarisiko chacho chakapetwa neganda jena resimbi, uye mashandiro emuchina ndiwo akanyanya kujairika uye ekutanga simbi mamakisi, ayo anogona chete kushandiswa kupeta nekuumba, kwete kutsika.Inoshandiswa kurumwa nemichina,
Semuenzaniso, goko refiriji, tangi yemafuta yemotokari, nezvimwe.
Zvigadzirwa zviri pamusoro pe ST13 zvinoshandiswa mumaindasitiri anoda kudhirowa kwakadzama, sekugadzira mota, matangi emafuta einjini dzedhiziri, nezvimwewo, izvo munhu anoshandisa zvinoenderana nezvinoda kudhirowa zvakadzika.
Musiyano uripo pakati peST12 neSPCC: Iwo ma mechanika ezvigadzirwa zviviri izvi anenge akafanana, asi nzira yekudzoka yakasiyana.Izvo zvinorema zvivakwa zve ST12 zvinhu zvine simba kupfuura izvo zveSPCC.
Japanese JIS yakajairika zvinhu zvinoreva
SPCC-S zvinoreva simbi (Simbi), P zvinoreva ndiro (Plate), C zvinoreva kutonhora (Kutonhora), C zvinoreva kutengeserana (Commerce), inova Japan JIS standard.
Kana iwe uchida kuve nechokwadi chekusimba kwesimba, wedzera T pakupera kwegiredhi, inova: SPCCT.
SPCD-inoratidza inotonhora-yakakungurutswa kabhoni simbi pepa uye tambo yekutsikisa, iyo yakaenzana neChina's 08AL (13237) yepamusoro kabhoni structural simbi.
SPCE-Inoratidza inotonhora-yakakungurutswa kabhoni simbi pepa uye tambo yekudhirowa kwakadzika, iyo yakaenzana neChina's 08AL (5213) yakadzika yekudhirowa simbi.
Kana kusiri-nguva kuchidikanwa, wedzera N pakupera kwegiredhi kuti ive SPCEN.
Cold-yakakungurutswa kabhoni simbi pepa uye simbi strip inodzima uye kupisa kodhi: annealed state is A, standard quenching uye tempering is S, 1/8 kuomarara 8, 1/4 kuomarara ndiko 4, 1/2 kuomarara ndiko 2, kuomarara kuzere ndiko 1. Surface processing code: D nokuda kwekusagadzikana kwekupedzisira kukunguruka, B nokuda kwekupenya kupedzisa.
Semuyenzaniso, SPCC-SD inomiririra yakajairwa kudzimwa uye kushatirwa, matte kupera kwakatenderedzwa general-chinangwa kutonhora-yakakungurutswa kabhoni pepa.
Mumwe muenzaniso ndeye SPCCT-SB, zvinoreva kudzima nekudzikamisa, kupenya kugadziridzwa, uye kutonhora-akakungurutswa kabhoni mapepa anoda vimbiso yemagetsi.
Mumwe muenzaniso ndeye SPCC-1D, zvinoreva kuti yakaoma matt kupera inotonhora-yakakungurutswa kabhoni simbi sheet.
Iyo nzira yekutaura yemagiredhi esimbi ezvimiro zvemechani ndeiyi: S + kabhoni yemukati + tsamba kodhi (C, CK), uko kabhoni yemukati inomiririrwa neiyo yepakati kukosha * 100, iyo C inomiririra kabhoni, uye vara K inomiririra carburizing simbi. .Semuenzaniso, kabhoni knot coil S20C ine kabhoni yemukati ye0.18-0.23%.
China GB yakajairika zvinhu zvinoreva
Chaizvoizvo yakakamurwa kuita:
Q195, Q215, Q235, Q255, Q275, nezvimwe.
Q inomiririra tsamba yekutanga yeChinese pinyin yezwi rekuti "Qu" pane goho resimbi, uye 195, 215, nezvimwe zvinomiririra kukosha kweiyo goho point.
Panyaya yekuumbwa kwemakemikari, yakaderera kabhoni simbi mamakisi:
Iyo yakakura mamakisi eQ195, Q215, Q235, Q255, uye Q275, iyo yakakwira iyo kabhoni yemukati uye manganese zvirimo, uye zvakanyanya kugadzikana mapurasitiki.
2. Muchidimbu sumo yesimbi inopisa-dip galvanized simbi (silver white)
Iyo inogadzirwa neinopisa-yakakungurutswa simbi tambo kana inotonhora-yakakungurutswa simbi tambo se substrate kuburikidza inoenderera inopisa-dip galvanizing process, iyo inogona kudzivirira pamusoro pesimbi yakatetepa ndiro uye simbi tambo kubva mukuora uye ngura.
Iyo inopisa-dip galvanized sheet inopihwa serectangular flat plate nekucheka-cheka;iyo inopisa-dip galvanized coil inopihwa semupumburu nekukochekera.
Nekuda kweakasiyana substrates anoshandiswa, anopisa-dip galvanized simbi machira anogona kukamurwa kuita inopisa-yakakungurutswa galvanized sheet makoiri uye inotonhora-yakakungurutswa inopisa-dip galvanized sheet coils, ayo anonyanya kushandiswa mukuvaka, midziyo yemumba, mota, midziyo, zvekufambisa uye. maindasitiri emumba.Kunyanya kuvakwa kwesimbi, kugadzira mota, kugadzira hwindo resimbi uye mamwe maindasitiri.
1. Hunhu hwekupisa-dip galvanized steel sheet
Yakasimba corrosion kuramba, yakanaka yepamusoro mhando, yakanaka kune yakadzika kugadzirisa, hupfumi uye inoshanda, nezvimwe.
