Xa kuziwa ekwakhiweni kweenqanawa, izakhiwo ze-offshore kunye nezinye izicelo zaselwandle, ukukhethwa kwezinto eziphathekayo kubalulekile. Phakathi kweendlela ezahlukeneyo ezikhoyo, iiplati zetsimbi ezishushu ezishushu, ngokukodwa iiplate zetsimbi zaselwandle, zivelele kwiipropati zabo ezizodwa kunye neenzuzo. Kule nqaku, siza kuhlolisisa iiyantlukwano phakathi kwamacwecwe ashushu ashushu kunye nabandayo, kutheni amacwecwe ashushu ashushu afaneleke ngakumbi kwizicelo zaselwandle, kunye namabakala ahlukeneyo amacwecwe ensimbi yaselwandle akhoyo kwiimarike, ngokugxininisa ngokukodwa kwiimveliso zeJindalai Steel.
Qonda iipleyiti eziqengqelekayo ezishushu kunye neepleyiti eziqengqelekayo ezibandayo
Umahluko omkhulu phakathi kwepleyiti epholileyo eshushu kunye ne-cold rolled plate yinkqubo yokuvelisa. Ipleyiti eqengqelekayo eshushu iveliswa ngokuqengqeleka kwentsimbi kumaqondo obushushu aphezulu, adla ngokuba ngaphezulu kwe-1,700°F. Inkqubo ivumela ukuba intsimbi yenziwe lula, ibangele imveliso engabizi kakhulu kunye ne-rougher surface finish. Ngokwahlukileyo, iipleyiti ezipholileyo zicutshungulwa kwiqondo lokushisa legumbi kwaye zinendawo epholileyo kunye nokunyamezela, kodwa kubiza ngaphezulu.
Ukusetyenziswa kolwandle, ipleyiti eshushu eqengqelekayo idla ngokukhethwa ngenxa yobuchule bayo obugqwesileyo kunye nokuqina. Ezi zakhiwo zibalulekile kwizakhiwo ekufuneka zimelane nemekobume erhabaxa yaselwandle, kubandakanywa ukudleka kwamanzi etyuwa kunye neemeko zemozulu ezimandundu. Ukukwazi ukufunxa amandla kunye nokukhubazeka ngaphandle kokwaphuka kwenza ipleyiti yentsimbi eshinyeneyo eshushu ilungele ukwakhiwa kweenqanawa kunye nolwakhiwo lwaselwandle.
Kutheni ipleyiti yentsimbi eqengqelekayo eshushu ifanelekile kwizicelo zaseLwandle
Iipleyiti zaselwandle ezisongwe ezishushu ziyilelwe ukuhlangabezana neemfuno ezingqongqo zemo engqongileyo yaselwandle. Inkqubo yokushisa ephezulu yokushisa iphakamisa iimpawu zomatshini zentsimbi, okwenza kube lula ukujamelana noxinzelelo olufunyenwe kwizicelo zaselwandle. Ukongeza, ipleyiti eshushu iyakwazi ukuveliswa kwiigeyiji ezityebileyo, ezihlala ziyimfuneko kulwakhiwo lweenqanawa kunye namaqonga angaphesheya.
Enye yeenzuzo eziphambili zokusebenzisa i-hot-rolled marine steel plate kukulula kwayo ukuwelda. Oku kubaluleke kakhulu kwishishini lokwakha iinqanawa, apho iziqwenga ezinkulu zetsimbi kufuneka zidityaniswe ukuze zenze ulwakhiwo oluqinileyo nolungenamanzi. I-weldability yamacwecwe ashushu ashushu aqinisekisa amajoyina anamandla kwaye athembekileyo, ukunciphisa umngcipheko wokungaphumeleli ngexesha lokusebenza.
Ibakala leplate yentsimbi yaselwandle
Iipleyiti zetsimbi zaselwandle zifumaneka kwiindidi ezahlukeneyo, nganye yenzelwe ukuhlangabezana nemigangatho ethile yokusebenza. Amanqaku aqhelekileyo aquka:
- AH36: Eyaziwa ngokuba namandla aphezulu kunye nokuqina, i-AH36 isetyenziswa ngokuqhelekileyo ekwakheni iinqanawa kunye nezakhiwo zangaphandle.
- I-DH36: Ngokufana ne-AH36, kodwa ngokuqina okuphuculweyo, okufanelekileyo kwizicelo kwiindawo ezibandayo.
- EH36: Ibonelela ngamandla awongezelelekileyo kwizicelo ezifuna ukusebenza okuphezulu phantsi kweemeko ezigqithisileyo.
I-Jindalai Steel inikezela ngoluhlu lwala mabakala e-hot rolled marine steel plate, ukuqinisekisa ukuba abathengi banokufumana izinto ezifanelekileyo kwiimfuno zabo ezithile. Ukuzibophelela kwabo kumgangatho kunye nokusebenza kubenze baba ngumthengisi othembekileyo kushishino lwaselwandle.
ukuququmbela
Isishwankathelo, ukukhethwa kwamacwecwe ashushu, ngokukodwa amacwecwe ensimbi yaselwandle, kubalulekile ekuhlalaneni nasekukhuselekeni kwezakhiwo zaselwandle. Iinzuzo zeplate eshushu, kubandakanywa i-ductility, i-weldability kunye nokukwazi ukumelana neemeko ezinzima, yenza kube yinto yokuqala yokukhetha abakhi beenqanawa kunye neenjineli zaselwandle. Ngoluhlu olubanzi lwamabakala akhoyo, kubandakanywa nalawo anikezelwa yiJindal Steel, izinto ezifanelekileyo zinokukhethwa ukuhlangabezana neemfuno zayo nayiphi na iprojekthi yolwandle. Njengoko ishishini liqhubeka nokuphuhlisa, uphuhliso lwezixhobo ezikumgangatho ophezulu ezifana neepleyiti zentsimbi ezishinyeneyo eziqengqelekayo kwintsimi yezakhiwo zentsimbi ziya kuhlala zibalulekile.
