Elongation ntau dua los yog sib npaug rau 22%: Muab kev hloov pauv yooj yim rau cov txheej txheem txias xws li dabtsi yog khoov thiab dov .

Kev Cuam Tshuam: Tau ua tiav ntau dua lossis sib npaug rau 34 j ntawm chav kub (v-motch), nrog xaiv {{2} Cov txheej txheem huab cua kev nyab xeeb muaj rau cov phiaj xwm huab cua sov {}}

Corrosion Kuj

Yus tus kheej kho patina: Dhau 3-6 lub hlis, ib txheej ruaj khov (50-100 μm tuab) cov ntaub ntawv, tsim lub ntuj thaiv kev tawm tsam oxidation inxidation.

Cov Huab Cua Highing Performance index (Kuv ntau dua los yog sib npaug rau 6.0): Suav raws liI {= 26.01 cu + 3.88 p} p} p} 2}+ 1.49 ni ni, tshaj kev lag luam cov qauv rau lub sijhawm ntev durability nyob rau hauv harsh huab cua.

Cov txheej txheem tsim khoom
Tsim ntawmThermo-neeg kho tshuab tswj kev ua (TMCP), Q310gnh undergoes:

Ua kom zoo nkauj smelting: Lf rauv desulfurization ua kom muaj tsawg dua lossis sib npaug rau 0 {.} 015%, txo kev cuam tshuam.

Precision Dov: Thaum kawg dov ntawm 820 - 860} degree, ua raws li kev ua kom nrawm dua lossis muaj zog ua kom zoo thiab muaj zog.

Kev ua kom zoo: Nug kev txhaj tshuaj tiv thaiv blasting lossis tshuaj oxidation kev kho txhim kho cov txheej nplaum adhesion rau cov kev siv tshwj xeeb {}}

1. Dab tsi yog cov qauv Q3xgnhghlhghhhghhring hlau seem tsim rau?

Teb:Nws yog tsim rau cov kev siv cov ntawv thov thauj khoom hauv cov tuam tsev muaj kev lag luam, xav tau cov laj thawj zoo, xav tau cov kev lag luam zoo dua thiab tshuab kev ua haujlwm {2}

2. Tus qauv twg Q310gnh ua raws?

Teb:Nws ua raws li GB / t 4171-2008.

3. Dab tsi yog cov khoom tseem ceeb ntawm Q310Gnh cov qauv sib txawv?

Teb:

Paib lub zog:Ntau dua los yog sib npaug rau 310 MPa (txhawb nqa nruab nrab-rau-siab loads rau kab teeb thiab kab ntawv).

Lub zog tensile:Ntau dua los yog sib npaug rau 450 mpa.

Elongation:Ntau dua los yog sib npaug rau 22% (ua rau kom txias tsim ntawm khoov / dov) .

Kev Cuam Tshuam:Ntau dua los yog sib npaug rau 34 j ntawm chav sov (v-notch), nrog xaiv {{2}℃xeem rau cov huab cua txias {}}

4. Q310gnh txhim kho corrosion ua li cas?

Teb:

Kev Kho Mob Rau Yus Tus Kheej Patina (-Feooh):Cov ntaub ntawv A 50-100 μm ntom ntom nti Txheej dua 3-6 lub hlis, txo tus nqi corrosion rau 1/2-1 / 8 tias ntawm cov pa roj carbon hlau.

Cu-P-CR-ni microalloaly system:Tooj liab, phosphorus, phosphorus, chromium, thiab npib sib koom ua ke tsim cov txheej txheem tiv thaiv oxide (kuv ntau dua lossis sib npaug 0) tshaj kev lag luam.

5. Dab tsi yog cov kev ua haujlwm thiab kev tsim khoom zoo ntawm Q310gnh?

Teb:

Tshuaj lom neeg cov khoom siv tshuaj lom neeg:

Cov pa roj carbon (C tsawg dua lossis sib npaug rau 0 {. 12%) kom ntseeg tau Weldability thiab ductility rau cov fabriccic.

Nruj sulfur tswj (s tsawg dua los yog sib npaug ntawm 0 {{. 02% txo cov brittleness kub rau kev siv zog.

Txheej txheem tsim khoom:

Thermo-neeg kho tshuab tswj kev ua (TMCP):Refined SMELTING (LF Rauv Rauv Dovulfurization, s tsawg dua lossis sib npaug nrog 550 qib) Txhim kho cov qauv zeb ua kom lub zog thiab tawv.

Nto Optimization:Xaiv tau txhaj tshuaj tiv thaiv / tshuaj oxidation txhim kho cov txheej txheem nplaum rau kev xav tau tshwj xeeb .

Lub neej yuav txuag tau nyiaj li cas:Minimizes txij nkawm los ntawm txog li 50% piv rau cov hlau tshuab .
