S890Q tshuaj xyuas li cas rau kev tswj kom zoo?

S890Qyog siab -lub zog quenched thiab tempered structural steel qib, feem ntau yog siv nyob rau hauv hnyav engineering, kev tsim kho machinery, thiab load- bearing lug qhov tshwj xeeb lub zog thiab zoo toughness yuav tsum tau. Nws belongs rau Q series ntawm nplua -cov qauv steels, nrog "890" qhia nws qhov tsawg kawg nkaus yield zog nyob rau hauv MPa thiab "Q" signifying quenched thiab tempered cua sov kho. Cov khoom siv zoo heev weldability thiab formability thaum ua raws li cov txheej txheem tsim nyog, ua rau nws tsim nyog rau fabricating loj thiab complex Cheebtsam uas yuav tsum tau tiv taus high stresses thaum tswj cov txheej txheem kev ncaj ncees.

Ua thiab Fabrication ntawm S890Q Steel

Kev ua tiav ntawm S890Q (ib qho quenched thiab Tempered ultra- siab- lub zog steel) yuav tsum muaj qhov tseeb thiab ua raws li cov kev txwv thermal tshwj xeeb los tiv thaiv kev degradation ntawm nws cov khoom siv kho tshuab.

1. Thermal thiab Mechanical Txiav

Nplaim taws (Oxy- roj) Txiav: Haum rau cov phaj tuab. Preheating rau 100℃-200℃yog yuav tsum tau rau thicknesses tshaj 30 hli kom tsis txhob txias cracking ntawm ntug.

Plasma Txiav: Ua tau zoo rau cov tuab tuab. Kev siv dej-txhaj tshuaj ntshav lossis ntshav qab zib hauv qab dej tuaj yeem txo qis dua qhov Heat Afected Zone (HAZ).

Laser txiav: Pom zoo rau siab -cov khoom muaj tseeb. Nws ua rau HAZ nqaim heev, uas khaws cov hlau tsis muaj zog.

Mechanical Cutting: Sawing lossis dej - dav hlau txiav yog qhov zoo tshaj plaws thaum tsis muaj kev cuam tshuam thermal.

2. Vuam raws tu qauv

S890Q muaj weldability zoo, tab sis nruj "tso tawm tswv yim" tswj yog tus yuam sij rau kev vam meej.

Thaum tshav kub kub input (t8 / 5 lub sij hawm): Yuav tsum tau ceev ceev (feem ntau 5-25 kJ / cm). Kev siv hluav taws xob siab tuaj yeem ua rau "softening" ntawm Heat Afected Zone, txo qhov sib koom ua ke lub zog tawm los.

Preheating thiab Interpass Temperature: Nyob ntawm phaj thickness thiab txwv, kub yuav tsum tau tswj ntawm 100℃thiab 225 degree.

Cov ntaub ntawv muab tub lim: Siv cov khoom siv qis- hydrogen consumables sib piv lub zog ntawm S890Q (piv txwv li, AWS A5.5 E11018 lossis zoo sib xws).

Tshaj tawm -Kev kho cua sov (PWHT): Feem ntau tsis pom zoo. Yog tias xav tau rau kev daws kev ntxhov siab, qhov kub thiab txias yuav tsum nyob qis dua 550℃kom tsis txhob poob ntawm tempering.

3. Txias thiab kub sib sau

Cold forming: Txheem txheej txheem rau khoov.

Bending Radius: Cov radii loj dua yuav tsum tau muab piv rau cov qauv hlau (feem ntau 3x rau 5x lub phaj tuab).

Springback: Qhov tseem ceeb elastic springback yuav tsum tau suav rau thaum lub sij hawm tsim cov cuab yeej.

Kub txoj kev: Yog hais tias cov khoom yog rhuab saum 580 degree, nws yuav poob nws "Quenched & Tempered" (Q + T) xeev. Tom qab kub sib sau, cov khoom yuav tsum tau ua kom tiav re-kev kho cua sov (quenching thiab tempering) los kho nws cov khoom S890Q.

4. Machining (Drilling thiab Milling)

Hardness: S890Q feem ntau muaj hardness ntawm 300-400 HBW.

Tooling: Siv siab -cov cuab yeej ua haujlwm carbide nrog cov txheej txheem siab heev (xws li TiAlN).

Kev teeb tsa: Xyuas kom lub tshuab tsis nruj thiab siv tus nqi noj tas li los tiv thaiv kev ua haujlwm nyuaj thiab cov cuab yeej sib tham.

5. Kev kho deg

Blasting: Kev txhaj tshuaj blasting yog pom zoo kom tshem tawm cov nplais ua ntej pleev xim lossis txheej.

Txheej: Tau tshaj -kev ua tau zoo tshaj plaws primers thiab xim siv hauv cov tshuab hnyav.

Galvanizing: Kev ceev faj yog xav tau thaum pickling kom tsis txhob muaj hydrogen embrittlement.

Qhov Zoo Tshaj Plaws

Qhov hnyav txo:Kwv yees li ntawm 2.5x muaj zog dua li tus qauv S355 steel, txo qhov hnyav ntawm cov qauv los ntawm30–40%.

Nce Payload:Tsawg deadweight ncaj qha txhim kho roj efficiency thiab load peev xwm thauj thiab nqa khoom.

High Toughness:Guaranteed cuam tshuam tsis kam ntawm qhov kub thiab txias los ntawm-20 degree(S890Q) mus-60 degree(S890QL1).

Economic Efficiency:Txo cov khoom ntim thiab txo cov kev xav tau ntawm vuam offset cov khoom siv ntau dua.

Cov ntawv thov tseem ceeb

Lifting:Mobile crane booms, pob zeb twj tso kua mis jibs, thiab siab - mus txog saum huab cua platforms.

Kev thauj mus los:Hnyav- lub luag hauj lwm trailer chassis, dumper lub cev, thiab tsheb thav duab.

Mining:Hydraulic ru tsev txhawb nqa, excavator caj npab, thiab tsuas tsheb cov qauv.

Kev tsim kho:Ntev- ncua kev txuas txuas txuas, lub hauv paus cua hauv ntug dej hiav txwv, thiab siab - thauj khoom lub tsev.

Zog:High -pressure penstocks rau hydropower thiab siab hlab ntsha.
