Shipbuilding DH36 Hlau Phaj

Kev ua ntawm Shipbuilding DH36 Steel Phaj

Shipbuilding DH36 Steel Phaj yog cov khoom siv tseem ceeb hauv kev lag luam shipbuilding, muaj npe nrov rau nws cov khoom siv zoo heev thiab ua haujlwm ntev. Cov txheej txheem tsim khoom ntawm cov phaj steel no yog ib qho nyuaj thiab tswj tau raws li kev ua haujlwm, xav tau qhov tseeb thiab kev txawj ntse ntawm txhua theem.

Kev taug kev ntawm Shipbuilding DH36 Steel Phaj pib nrog kev xaiv cov khoom siv raw. High-quality hlau ore, coke, thiab ntau yam alloying ntsiab yog ua tib zoo xaiv los xyuas kom meej qhov xav tau tshuaj muaj pes tsawg leeg ntawm cov khoom kawg. Cov ntaub ntawv raw li no tau nkag mus rau hauv lub qhov cub tawg, qhov chaw uas lawv raug kub hnyiab, yaj thiab tsim cov hlau sib tov.

Thaum tau txais cov hlau molten, nws nkag mus rau cov txheej txheem refining. Cov theem no yog qhov tseem ceeb rau kev tshem tawm cov impurities thiab hloov kho cov tshuaj muaj pes tsawg leeg kom ua tau raws li cov cai nruj ntawm qib DH36. Cov cuab yeej tshwj xeeb thiab cov txheej txheem yog ua haujlwm los saib xyuas thiab tswj qhov sib ntxiv ntawm cov hlau alloying, xws li manganese, npib tsib xee, thiab chromium, uas txhim kho cov hlau cov khoom xws li lub zog, toughness, thiab corrosion kuj.

Tom qab cov txheej txheem refining, molten steel yog cam khwb cia rau hauv slabs los yog ingots. Cov txheej txheem casting yog ua tib zoo tswj kom ua tiav ib homogeneous microstructure thiab txo qhov tsis xws luag xws li porosity thiab inclusions. Daim ntawv thawj zaug no muab lub hauv paus rau kev ua cov kauj ruam tom ntej.

Cov kauj ruam tom ntej yog kub dov. Cov cam khwb cia slabs los yog ingots yog reheated rau ib tug siab kub thiab dhau los ntawm ib tug series ntawm dov mills. Cov txheej txheem kub dov tsis tsuas yog txo cov thickness ntawm cov hlau, tab sis kuj ua kom zoo dua cov qauv nplej, txhim kho nws cov khoom siv kho tshuab. Lub siab thiab kub siv thaum kub dov yog tswj tau los xyuas kom meej tias cov phaj steel tau txais cov duab thiab cov khoom uas xav tau.

Tom qab kub dov, lub phaj hlau yuav raug tswj kom txias. Cov txheej txheem txias no yog qhov tseem ceeb vim nws cuam tshuam rau qhov kawg microstructure thiab txhua yam khoom ntawm DH36 phaj. Cov nqi sib txawv thiab cov txheej txheem tuaj yeem ua haujlwm kom ua tiav cov yam ntxwv tshwj xeeb, xws li nce hardness lossis txhim kho ductility, nyob ntawm daim ntawv thov.
