LR / DH40 Marine Steel Phaj

Cov txheej txheem tsim khoom thiab qhov tshwj xeeb ntawm LR / DH40 Marine Steel Phaj

LR / DH40 Marine Steel Phaj yog cov khoom tseem ceeb hauv kev lag luam marine, muaj npe nrov rau nws cov khoom zoo thiab ua haujlwm ntev. Nkag siab txog nws cov txheej txheem tsim khoom thiab qhov tshwj xeeb yog qhov tseem ceeb rau nws txoj kev siv tau zoo.

Kev tsim khoom ntawm LR / DH40 Marine Steel Phaj pib nrog kev xaiv cov khoom siv raw. High-zoo hlau ore, coke, thiab lwm yam alloying ntsiab raug xaiv los xyuas kom meej cov yam xav tau tshuaj muaj pes tsawg leeg ntawm cov hlau. Cov ntaub ntawv nyoos no yog tom qab ntawd yaj hauv lub cub tawg loj ntawm qhov kub siab heev los tsim cov hlau sib tov sib xyaw.

Thaum lub sij hawm melting txheej txheem, meej tswj qhov kub thiab muaj pes tsawg leeg yog qhov tseem ceeb. Cov additives tshwj xeeb yuav raug qhia los kho cov khoom ntawm cov hlau, xws li kev txhim kho nws lub zog, toughness, thiab corrosion kuj. Thaum cov hlau molten mus txog qhov xav tau muaj pes tsawg leeg thiab zoo, nws yog poured rau hauv pwm rau thawj shaping.

Tom qab solidification, semi-tiav steel slabs undergo ib tug series ntawm kub ua hauj lwm txheej txheem. Qhov no suav nrog kub dov, qhov twg cov slabs tau dhau los ntawm cov txheej txheem ntawm cov chais nyob rau hauv siab thiab kub kom txo lawv cov thickness thiab txhim kho microstructure. Cov txheej txheem kub dov refines cov qauv nplej ntawm cov hlau, txhim kho nws cov khoom siv kho tshuab.

Cov txheej txheem kev kho cua sov tom qab, xws li annealing thiab tempering, yog ua los txhawm rau txhim kho cov khoom ntawm steel phaj. Annealing pab txo cov kev ntxhov siab sab hauv thiab txhim kho ductility, thaum tempering kho qhov hardness thiab toughness sib npaug.

Kev tswj kom zoo yog ib feem tseem ceeb ntawm cov txheej txheem tsim khoom. Cov qauv raug coj mus rau ntau theem rau kev tshuaj ntsuam xyuas tshuaj thiab kev ntsuas tshuab kom ntseeg tau tias cov phaj hlau ua tau raws li cov qauv nruj thiab cov lus qhia tshwj xeeb rau qib LR / DH40.

Tam sim no, cia peb tig mus rau qhov tshwj xeeb ntawm LR / DH40 Marine Steel Phaj. Qhov ntev tuaj yeem sib txawv raws li qhov yuav tsum tau ua ntawm cov ntawv thov sib txawv thiab kev tsim khoom muaj peev xwm. Feem ntau, cov tuab ntawm cov hlau phaj no tuaj yeem nyob ntawm ob peb millimeters mus rau ob peb centimeters. Qhov dav tuaj yeem sib txawv ntawm ob peb puas millimeters mus rau ob peb meters, thiab qhov ntev tuaj yeem ncav cuag kaum meters.

Piv txwv li, nyob rau hauv tej rooj plaub, lub thickness tej zaum yuav 10 hli, 20 hli, los yog txawm 50 hli. Qhov dav tuaj yeem yog 1500 hli, 2000 hli, lossis 3000 hli, thiab qhov ntev yuav yog 6000 hli, 12000 hli, lossis kev cai ntev raws li cov neeg siv khoom xaj. Qhov tshwj xeeb qhov ntev yog txiav txim siab raws li cov qauv tsim ntawm cov qauv marine, xws li nkoj hulls, decks, thiab bulkheads.
