Kuumbwa kweMakemikari

Iyokuumbwa kwemakemikariyeAH36, DH36, uye EH36 yakafanana, yakagadzirirwa kuve nechokwadi chekuti yakasimba, inochinjika zvakanaka, uye inodzivirira ngura.

Kuumbwa Kwemakemikari Kwakajairika (%):

• Kabhoni (C):≤ 0.18

• Manganese (Mn):0.90–1.60

• Silikoni (Si):0.10–0.50

• Phosphorus (P):≤ 0.035

• Sarufa (S):≤ 0.035

• Niobium (Nb), Vanadium (V), Titanium (Ti):≤ 0.10

Zvinhu zvinosanganisa simbi zvakaita se niobium, vanadium, uye titanium zvinovandudza chimiro chegorosi, izvo zvinoita kuti simbi iwedzere kusimbaradzwa.kusimba, kuramba kuneta, uye simba remakanika.

Zvivakwa zveMichina

AH36, DH36, uye EH36zvese simbi dzakasimba zvikuru dzine zvakafananasimba shoma regoho re355 MPauyesimba rekudhonza rinotangira pa490 kusvika 620 MPa.

Zvimiro zveMichina Zvakajairika:

• Simba reKubereka:≥ 355 MPa

• Simba reKusimba:490–620 MPa

• Kureba (mu 50 mm):≥ 21%

• Kuoma (HB):170–220

Musiyano mukuru pakati pavo uri mukusimba kwemhedzisiro, yakayerwa kuburikidza nemiedzo yeCharpy V-Notch (CVN) patembiricha dzakasiyana:

• AH36 inoedzwa pa0°C.

• DH36 inoedzwa pa-20°C.

• EH36 inoedzwa pa-40°C.

Kana tembiricha yekuyedza yakaderera, simbi inogona kuramba yakasimba uye kudzivirira kutyoka kwakaoma munzvimbo dzinotonhora.

Kusiyana Kwakakosha Pakati peAH36, DH36, uye EH36

1. Kusimba Kwesimba

Musiyano wakakosha pakati pemagiredhi matatu ndewekutikuramba kutyoka kwakashatapakupisa kwakasiyana.

• AH36inoita zvakavimbika mumamiriro ekunze ari pakati nepakati, yakakodzera ngarava dzinoshanda mumamiriro egungwa akajairwa.

• DH36inopa kusimba kwakawedzerwa, zvichiita kuti ive yakakodzeranzvimbo dzinotonhora uye mapuratifomu ari pedyo negungwa.

• EH36inopa simba guru rekurwisa patembiricha dziri pasi pe zero, yakakodzeraKutakura zvinhu muArctic, LNG, uye ngarava dzemugungwa dzinofamba nepakati pegungwa.

Musiyano uyu unoita kuti giredhi rega rega rishandiswe uko rinogona kupa kuchengetedzeka kwakanyanya pasi pekumanikidzwa kwezvakatipoteredza.

2. Nzvimbo yekupisa yebasa

• AH36:Kushandiswa mumamiriro ekunze anodziya kusvika pakupisa(pamusoro pe 0°C).

• DH36:Zvemamiriro ekunze anotonhora(kusvika -20°C).

• EH36:Zvenzvimbo dzinotonhora zvakanyanya(kusvika -40°C).

Ngarava kana zvivakwa zvegungwa zvinoshanda munzvimbo dzine chando kana kuti dzine polar dzinoshandisa EH36 kudzivirira kutsemuka kwechivako nekuda kwekuoma kwechimiro kunokonzerwa nekupisa.

3. Nzvimbo Yekushandisa

Kunyange zvazvo magiredhi ese ari esimbi dzemugungwa, kushandiswa kwavo kunosiyana zvichienderana nekusvibiswa kwezvakatipoteredza:

• AH36:Zvikepe zvekutakura zvinhu, ngarava dzinotakura zvinhu, uye ngarava dzinotakura zvinhu zvakawanda.

• DH36:Nzvimbo dzekuchera matombo dziri kunze kwegungwa, matangi emvura anoyerera mugungwa, uye ngarava dzinofamba mumvura inotonhora.

• EH36:Ngarava dzinopwanya aizi, ngarava dzekuongorora dzemuchadenga, uye mapuratifomu egungwa rakadzika.

4. Kuedzwa uye Chitupa

Giredhi rega rega rinofanira kupasa zviyero zvebvunzo zvakasimba zvakatsanangurwa neBhizinesi reAmerica rekutumira zvinhu (ABS)nedzimwe nzvimbo dzekupatsanura. Musiyano uripo pakati petembiricha yekuedza kukanganisainoita kuti simbi yega yega ishande zvakachengeteka munzvimbo yayo yakatarwa.

Zvinhu Zvakajairika zveAH36, DH36, uye EH36

Kunyange zvazvo zvinodiwa pakuyedza simba remvura zvichisiyana, magiredhi matatu aya ane zvinhu zvakawanda zvinoita kuti akosheswe pasi rose mukuvaka gungwa.

1. Simba Rakakura-Kusvika-Kurema Chiyero

Simba ravo guru rinobvumira kugadzirwa kwezvivakwa zvengarava zvakareruka, zvakasimba, kuderedza kushandiswa kwezvinhu uye kushandiswa kwemafuta, izvo zvinovandudza kushanda zvakanaka kwesimba.

2. Kugona Kupinza Zvakanaka

Nekuda kwehuwandu hwekabhoni hwakagadziriswa uye dhizaini yesimbi, simbi idzi dzinonyatso sungirirwa uchishandisa nzira dzakajairwa dzekuputira dzakadai seMIG, TIG, uye kusanganisa arc welding pasi pemvura (SAW)pasina kupiswa kana kurapwa mushure mekupiswa.

3. Kuramba Kuora uye Kuneta

Yakagadzirirwa kugara ichiratidzwamvura ine munyu, hunyoro, uye kushushikana kwekufamba kwenguva, AH36, DH36, uye EH36 zvinopa zvakanaka kwazvokuramba ngura, oxidation, uye kuneta kutadza.

4. Kugara Kwenguva Refu

Kunyangwe kana paine kudedera, kurovera, uye kumanikidzwa kwemafungu nguva dzose, magiredhi aya anochengetedza chimiro chawo kwemakumi emakore, zvichiita kuti zvive zvakanaka kunezvikepe zvengarava, madheki, uye kuiswa kwemahombekombe.

5. Kutevedzera Mitemo Yepasi Pose

Magiredhi ese matatu anoenderana nezvinodiwa nemasangano makuru ekupatsanura:

• Bhizinesi reAmerica rekutumira zvinhu (ABS)

• Rejista yaLloyd (LR)

• Det Norske Veritas (DNV)

• Bhizinesi reVeritas (BV)

• Sangano reChina Classification (CCS)

Ndiro yega yega inopihwa nasakysteelinogona kuteverwa zvizere, neEN 10204 3.1/3.2 Mill Test Certificateskuve nechokwadi chekuti zvinhu zvose zvinoitwa nenzira yakakwana.

AH36, DH36, uye EH36 zvinoshandiswa zvakanyanya mukuvaka matanda ehull, plating yedheki, uye bulkheads, kuona kuti ngarava dzinoramba dzakagadzikana uye dzakachengeteka mugungwa rine simba.

2. Mapuratifomu ekunze

Mumichina yekuchera matombo iri kunze kwenyika uye masisitimu ekugadzira zvinhu zvinoyangarara, simbi dzeDH36 neEH36 dzinoshandiswamadheki makuru, makumbo anotsigira, uye matanda echivakwa, uko kusangana nemvura inotonhora yegungwa uye kushushikana kwakanyanya kunoda kusimba kwakanyanya.

3. Zvifambiso zveLNG nemidziyo inoyerera nemhepo

Simbi yeEH36 inonyanya kukodzerakushandiswa kwe cryogenic, kuchengetedza ductility yakanaka kunyangwe patembiricha iri pasi pe zero, izvo zvakakosha pakuchengetedza nekutakura magasi ane mvura.

4. Ngarava dzeMugungwa nedzeMasoja

Nekuda kwavosimba guru uye kuramba kukanganiswa, simbi idzi dzakanakirangarava dzehondo, zvikepe zvekuchengetedza, uye ngarava dzekudzivirira, zvichipa kugara kwenguva refu uye kuvimbika kwechivakwa pasi pekuremerwa kwakasimba.

5. Maturbine emhepo ari kunze kwegungwa

Sezvo indasitiri yesimba rinogona kushandiswazve iri kuwedzera mumahombekombe, simbi dzeAH36 neDH36 dziri kushandiswa zvakanyanya muzvivakwa zvenheyo, shongwe dzinotsigira, uye mapuratifomu ari pasi pemvura, uko ngura uye kuramba kuneta zvakakosha.
