CCS FH40 Marine Steel Plate

Ipleyiti yentsimbi yaselwandle ibhekiselele kwintsimbi yesakhiwo esetyenziswa kwisakhiwo senqanawa. Ithathwa njengenqanaba lolwandle kwaye kufuneka ikwazi ukuxhathisa iziphumo ezinobungozi eziqhelekileyo kwindawo yamanzi. Ukufezekisa oku, izinto ezikhethekileyo ze-alloying zongezwa kula mabanga ukwenzela ukukhusela i-agaist corrosion.Nangona ininzi ye-carbon steel ayifanelekanga kwiindawo zaselwandle, kukho iindidi ezininzi zeentsimbi zekhabhoni zolwandle ezivunyiweyo yimibutho eyahlukeneyo yezicelo zokwakha iinqanawa.

Intsimbi yolwakhiwo yeenqanawa zenqanawa yohlulwe ngokweeklasi zokomelela ngokokomelela kwayo okuphantsi kwesivuno: ukomelela ngokubanzi kwentsimbi yolwakhiwo kunye nokomelela okuphezulu kwentsimbi yesakhiwo. Ipleyiti yensimbi yaseMaine ibhekiselele kwipleyiti yentsimbi eshushu eveliswe ngokuhambelana neemfuno zoluntu lweklasikhi yokwakhiwa kwezakhiwo zenqanawa.

Kukho imibutho ye-9 ephambili yokuhlela kwihlabathi jikelele.

Intsimbi yeCCSFH40 luhlobo lwentsimbi eshushu eqengqelekayo. I-CCS ephezulu yokwakhiwa kwentsimbi yentsimbi ifika kumabakala e-12 yamandla e-3, i-FH40 yenye yamabakala. Iiplati zentsimbi ze-CCS FH40 zivelisa amandla e-56,500 psi (390 MPa), kunye namandla okugqibela e-74,000 - 94,500 psi (510-650 MPa). Zonke iinqanawa ze-CCSFH40 zeNsimbi ezinikezelwa yiGnee zinokuqinisekiswa yiCCS

I-CCS lilungu eliseka i-International Association of Classification Societies(IACS), eyasekwa ngo-1968. Inqwelo ye-CCS yamkelwa malunga ne-116 yamagunya eflegi kumazwe ngamazwe. Iinkonzo ezidityanisiweyo zeCCS zomjikelo wokuthumela ngenqanawa kubandakanya uyilo, ukwakhiwa, ulawulo lwendawo yeenqanawa, ukuhlolwa kunye novavanyo lwezixhobo / amacandelo kunye nokuhlolwa rhoqo ukugcina iklasi isetyenziswa yimpahla, izikhephe, i-ro-ro, iinqanawa zabakhweli, iiyachts, iinqanawa zokuhamba ngenqanawa. , i-navy, i-LGN kunye nezinye iinqanawa zokuthwala iingcali.


Intsimbi yeBakala AH40 ngamandla empembelelo aphantsi kwe-0 ° C
IBanga le-DH40 lempembelelo yentsimbi kwi- -20 ° C
IBanga le-EH40 amandla empembelelo yentsimbi kwi -40 ° C
IBanga le-FH40 amandla empembelelo yentsimbi kwi -60 ° C

Inkonzo yokuqhushumba kweembumbulu
Ukuqhushumba kwembumbulu yindlela esetyenziswa ukucoca okanye ukupolisha intsimbi xa kufuneka kugqitywe umphezulu ophuculweyo. Ukudubula kusetyenziswa phantse kuwo onke amashishini esiwasebenzelayo. Ngokukodwa kulwakhiwo lweenqanawa, uloliwe, ulwakhiwo lolwakhiwo kunye nokunye.

Uluhlu lweenkcukacha

Ukuqhubela phambili amaBanga ahlukeneyo
IBakala D, E (DH32, DH36, EH 32, EH 36)
Uluhlu lweBanga D kunye no-E (inlcuding AH32 / 36, DH32, DH36, EH32, EH36) iiplati zentsimbi zokwakha iinqanawa zifuna ukuqina kobushushu obuphantsi kunye nokusebenza kakuhle kwe-welding. Imveliso yentsimbi yokwakhiwa kwenqanawa ephezulu yokwakhiwa kwenqanawa kufuneka iqheleke ngendlela yokulawula ukuqengqeleka nokulawulwa kokupholisa okanye iinkqubo zonyango olushushu kunye nezixhobo ezipheleleyo. Ngelo xesha, ukucoceka kwensimbi yangaphakathi kweebhilithi ezibonelelweyo kufuneka kube phezulu, ngokukodwa umxholo we-S, P, N, 0 kunye no-H kwintsimbi kufuneka ilawulwe ngokungqongqo.

Izinto ze-alloy zongezwa ekuphuculeni ukuqina
Ukuze kuqinisekiswe ukusebenza kweeplati zeenqanawa eziphezulu, iteknoloji ye-micro-alloying yamkelwa. Ngokungeza i-Nb, i-V, i-Ti kunye nezinye izinto ezixutywayo kwintsimbi, idibaniswe nenkqubo yokulawula elawulwayo, ingqolowa ihlanjululwe kwaye ukuqina kuphuculwe.
Isalathiso soPhuhliso lwePlate yoKwakha iinqanawa
Amandla aphezulu, ukucaciswa okuphezulu, kunye nobukhulu benqanawa kunye nokhuseleko, kunye notshintsho kwiinkcukacha zokugquma, imfuno yeepaneli eziqhelekileyo ze-A-class iyancitshiswa ngokuthe ngcembe, kwaye imfuno yeepaneli zamandla aphezulu iyanda, egxininiswe kwiinqanawa ezinkulu. malunga ne-5m ububanzi. Icwecwe, 200-300mm ubukhulu ibhodi yenqanawa eshinyeneyo ekhethekileyo.
