AH36 yog lub zog siab steel phaj rau lub nkoj hull cov qauv thiab belongs rau lub nkoj phaj series. Nws yog dav siv nyob rau hauv offshore platforms, roj thiab roj kis tau tus mob pipelines, loj ships, txuas hniav thiab lwm yam uas yuav tsum tau muaj zog. Qib ntawm AH36 steel phaj sawv cev rau nws cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv kho tshuab, thiab ua tau raws li cov kev cai ntawm cov kev faib tawm thoob ntiaj teb (xws li ABS, DNV, GL, LR, BV, CCS, NK, KR, RINA, thiab lwm yam).
Qib ntawm AH36 steel phaj muaj ntau yam. Thawj yog tsab ntawv "A", qhia tias qhov no yog marine steel. Tom ntej no yog qhov "H" qhia tias qhov no yog cov hlau muaj zog. Tus lej "36" qhia txog qib siab ntawm cov hlau phaj, thiab chav tsev yog kilopascal (kPa). Yog li ntawd, lub zog ntawm AH36 steel phaj yuav tsum ncav cuag ntau tshaj 36000kPa. Tsis tas li ntawd, AH36 steel phaj kuj muaj kev sib txuas zoo heev thiab kev tiv thaiv corrosion, thiab tuaj yeem ua tau raws li cov kev cai tshwj xeeb ntawm thaj chaw marine.
Thaum lub sij hawm tsim cov txheej txheem, AH36 steel daim hlau yuav tsum tau mus los ntawm ntau yam txheej txheem thiab nruj soj ntsuam. Ua ntej, xaiv cov ntaub ntawv zoo, xws li hlau ore, seem hlau, thiab lwm yam, rau smelting. Thaum lub sij hawm smelting txheej txheem, tsis xws li kub, muaj pes tsawg leeg, thiab oxygen cov ntsiab lus yuav tsum tau tswj kom zoo thiab purity ntawm molten hlau. Tom qab ntawd, cov hlau molten yog poured rau hauv steel ingots thiab ua tiav rau hauv steel daim hlau los ntawm kub dov, txias dov thiab lwm yam txheej txheem. Thaum lub sij hawm tus txheej txheem no, tsis xws li dov kub, dov ceev, thiab txo yuav tsum tau tswj kom tau lub zoo tagnrho thickness, dav, thiab flatness ntawm steel phaj.
Tom qab ua tiav ntawm kev ua tiav, AH36 steel phaj tseem yuav tsum tau ua ntau yam kev tshuaj xyuas thiab kev sim. Xws li tshuaj lom neeg muaj pes tsawg leeg kev soj ntsuam, kev ntsuam xyuas cov cuab yeej cuab tam, kev tshuaj xyuas cov qauv metallographic, kev kuaj tsis muaj kev puas tsuaj, thiab lwm yam. Cov kev tshuaj ntsuam xyuas thiab kev ntsuam xyuas no yog tsim los xyuas kom meej tias qhov zoo thiab kev ua haujlwm ntawm cov hlau phaj ua tau raws li tus qauv yuav tsum tau ua. Tsuas yog cov ntawv hlau uas dhau qhov kev tshuaj ntsuam xyuas thiab kev ntsuam xyuas no tuaj yeem lees paub tias yog AH36 steel daim hlau uas tsim nyog thiab siv los tsim ntau yam kev lag luam hauv hiav txwv thiab cov qauv nkoj nrog lub zog siab.
Ntxiv nrog rau kev tswj kom zoo thaum lub sijhawm tsim khoom, kev siv AH36 steel daim hlau kuj yuav tsum tau ua raws li qee cov qauv thiab cov qauv. Piv txwv li, cov khoom siv vuam tsim nyog thiab cov txheej txheem yuav tsum raug xaiv thaum lub sij hawm vuam txheej txheem los xyuas kom meej qhov zoo thiab kev ua tau zoo ntawm cov welded sib koom. Thaum siv, kuj yuav tsum tau them nyiaj rau kev tiv thaiv corrosion thiab kev saib xyuas ntawm cov hlau phaj kom ntev lawv lub neej kev pab thiab kev nyab xeeb.
