Thaum xaj cov qauv hlau zoo li S335J2WP Corten Steel, qhia qhov tseeb "kev xa khoom" yog qhov tseem ceeb raws li tau txais txoj cai chemistry. Lo lus no txhais tau hais tias lub thermo- kho tshuab lub phaj tau dhau los ntawm lub zeb, cuam tshuam ncaj qha rau nws cov khoom siv kho tshuab, fabricability, thiab, thaum kawg, nws qhov kev ua tau zoo hauv koj qhov project.
Rau S335J2WP, ob qho kev xa khoom feem ntau yog Normalized (N) thiab Thermo-Mechanically Rolled (M). Nkag siab qhov txawv yog qhov tseem ceeb rau kev txiav txim siab xaiv.
Ob Qhov Kev Xa Khoom Tseem Ceeb
1. Normalized (N lossis + N)
Nws yog dab tsi:Tom qab pib kub dov, lub phaj steel yog reheated rau qhov kub siab (siab tshaj 900 degree) thiab ces tso cai rau txias nyob rau hauv tseem huab cua. Cov txheej txheem no refines lub grain qauv, ua rau nws uniform thiab homogeneous thoob plaws lub thickness.
Cov txiaj ntsig tseem ceeb:
Consistent Properties: Provides very uniform mechanical properties, especially important for thick plates (>15-20mm).
Zoo heev Toughness:Txhim khu kev cuam tshuam toughness, qhov tseem ceeb tshaj plaws rau cov qauv hauv cov huab cua txias.
Fabrication Flexibility:Cov qauv homogeneous muaj kev txhim khu kev qha rau kev vuam txuas ntxiv thiab kev ua haujlwm nruab nrab.
2. Thermo-Mechanically Rolled (M lossis +M)
Nws yog dab tsi:Kuj hu ua TMCP (Thermo-Mechanical Controlled Process), qhov no yog cov txheej txheem siab dua. Cov hlau yog dov nyob rau hauv ib qho tshwj xeeb, tswj qhov kub thiab txias ntawm tus nqi nrawm. Qhov no ua tiav qhov zoo - nplej, siab - lub zog microstructuretsis muajqhov xav tau rau lub voj voog rov ua dua tshiab.
Cov txiaj ntsig tseem ceeb:
Siab zog - rau - Nyhav:Tso cai rau kev siv cov seem thinner thaum ua tau raws li qhov yuav tsum tau muaj zog, muaj peev xwm txuag tau qhov hnyav.
Zoo Weldability:Feem ntau muaj qis dua cov pa roj carbon monoxide, uas tuaj yeem ua rau vuam yooj yim dua nrog kev pheej hmoo ntawm qhov tsis xws luag.
Zog txuag:Cov txheej txheem feem ntau ua tau zoo dua li normalization, uas tuaj yeem cuam tshuam txog tus nqi thiab kev cuam tshuam ib puag ncig.
Yuav Xaiv Li Cas: Phau Ntawv Qhia Txog Tswv Yim
Koj qhov kev xaiv ntawm Normalized (N) thiab Thermo-Mechanically Rolled (M) S335J2WP yuav tsum tau coj los ntawm koj qhov kev thov tshwj xeeb:
Xaiv Normalized (N) yog tias:
Koj tus qauv sivcov ntu tuab (often >25 mm).
Cov qauv xav tauguaranteed cuam tshuam toughness ntawm qis kev pab cuam kub(piv txwv li, -20℃rau -30 degree).
Koj cia siab tias tseem ceebtom qab- ua los yog kev kho cua sovtom qab xa khoom los ntawm lub zeb.
Xaiv Thermo-Mechanically Rolled (M) yog:
Koj ua haujlwm nrognruab nrab thicknesses.
Optimizing hnyav thiab cov khoom siv efficiencyyog qhov tseem ceeb.
Txoj haujlwm no suav nrog kev vuam dav, thiab koj nrhiav cov khoom siv uas muaj qhov zoo tshaj plaws weldability.
Kev Ceeb Toom Tseem Ceeb
Ib txwm Qhia meej hauv Kev Yuav Khoom:Kev xa khoom tsis yog ib qho kev nthuav dav xwb; nws yog ib feem tseem ceeb ntawm cov khoom specification. Rau S335J2WP, koj yuav tsum qhia meej meej koj qhov kev xav tau, piv txwv li: "TS EN 10025-5: S335J2WP + N"rau normalized los yog"+M" rau cov thermo-mechanically dov.
Tham Thaum Ntxov:Sib tham txog cov txheej txheem tsim khoom tsim (tshwj xeeb tshaj yog cov txheej txheem kub) thiab ib puag ncig kev pabcuam nrog koj tus neeg xa khoom steel lossis tus kws pab tswv yim metallurgical. Lawv tuaj yeem qhia txog qhov tsim nyog tshaj plaws thiab tus nqi -zoo rau koj daim ntawv thov.
Hauv cov ntsiab lus, thaum ob qho tib si Normalized thiab Thermo-Mechanically Rolled S335J2WP Corten Steel ua tau raws li tus qauv cov cai, qhov kev xaiv cuam tshuam rau lub zog, tawv, thiab koj ua haujlwm li cas nrog cov khoom. Kev qhia txog qhov raug xa tawm los ntawm qhov pib ua kom cov hlau ua tau raws li qhov xav tau hauv koj cov qauv tiav.
