Marine Shipbuilding High Strength Steel Phaj

 

Cov txheej txheem tsim khoom ntawm AH32 kub dov shipbuilding marine steel phaj muaj cov cai tshwj xeeb hauv cov hauv qab no:

 

Kev xaiv raw khoom:

Base hlau: Kev xaiv cov hlau nyoos yog qhov tseem ceeb. Cov ntsiab lus carbon yuav tsum tau tswj nruj me ntsis, feem ntau tsis tshaj 0.20% kom ntseeg tau zoo weldability thiab toughness.

Cov hlau alloy: Tsim nyog cov khoom alloy xws li manganese, niobium, titanium, thiab vanadium ntxiv. Manganese yog lub ntsiab alloying, uas tuaj yeem txhim kho lub zog thiab toughness ntawm cov hlau. Cov kab ntau ntawm niobium, titanium, lossis vanadium tuaj yeem tsim cov carbides zoo lossis carbonitrides hauv cov hlau, pab kom tau txais cov nplej zoo ferrite thiab txhim kho lub zog thiab tawv ntawm cov hlau. Tsis tas li ntawd, ib qho me me ntawm tooj liab (tsawg dua lossis sib npaug rau {{0}}.4%) thiab phosphorus (txog 0.1%) tuaj yeem muab ntxiv los txhim kho corrosion kuj. Thiab ib qho me me ntawm cov ntsiab lus tsis tshua muaj hauv ntiaj teb tuaj yeem muab ntxiv rau desulfurize, degasify, purify cov hlau, thiab txhim kho lub toughness thiab cov txheej txheem kev ua tau zoo.

Smelting txheej txheem:

Txoj kev Smelting: Feem ntau, hluav taws xob rauv smelting yog siv los xyuas kom meej lub purity ntawm cov hlau. Cov txheej txheem smelting yuav tsum nruj me ntsis tswj cov ntsiab lus ntawm impurities xws li sulfur, phosphorus, nitrogen, oxygen, thiab hydrogen hauv cov hlau kom tau raws li qhov yuav tsum tau ua 3.

Kev kho kom haum: Thaum lub sij hawm smelting txheej txheem, cov muaj pes tsawg leeg ntawm cov hlau yog kho nyob rau hauv real-time raws li tsim tshuaj muaj pes tsawg leeg yuav tsum tau kom paub meej tias cov ntsiab lus ntawm txhua lub caij nyob rau hauv lub cheeb tsam.

Casting txheej txheem:

Casting kub: Qhov kub ntawm casting yuav tsum tau tswj kom raug. Yog tias qhov kub thiab txias dhau lawm, nws yuav ua rau muaj qhov tsis xws luag xws li porosity thiab kev sib cais hauv cov hlau; yog tias qhov kub thiab txias qis dhau lawm, nws yuav ua rau tsis txaus filling ntawm pwm thiab lwm yam teeb meem.

Pwm xaiv: Cov pwm tsim nyog raug xaiv los xyuas kom meej cov duab thiab qhov tseeb ntawm cov cam khwb cia. Nyob rau tib lub sijhawm, kev ntsuas xws li pwm kev co thiab kev tswj cua txias yog coj los txhim kho qhov zoo ntawm cov cam khwb cia.

Rolling txheej txheem:

Rolling kub: Cov cua kub ntawm cov slab ua ntej dov yog ib qho tseem ceeb parameter. Nws yuav tsum tau rhuab mus rau ib tug haum kub ntau yam kom paub meej tias cov hlau muaj zoo plasticity thiab formability thaum dov. Qhov pib dov kub yog feem ntau nyob ib ncig ntawm 1100-1200 degree , thiab qhov ua tiav dov kub yog tswj ntawm li 850-950 degree .

Rolling txo: Qhov tsim nyog rolling txo yog teem rau txhua qhov dhau ntawm dov los xyuas kom meej tias cov qauv sab hauv ntawm cov hlau tsis sib xws thiab cov khoom siv kho tshuab ruaj khov. Tag nrho cov dov txo qhov piv txwv feem ntau yog tswj nyob rau hauv ib qho chaw kom tau raws li qhov xav tau phaj thickness thiab kev ua tau zoo.
