Txias txoj kev hloov pauv tiaj tus SMA400CW Corten Steel nplooj ntawv rau hauv kev cai nkhaus choj railings, angular structural brackets, thiab complex architectural profiles-tab sis qhov kev coj tsis ncaj tuaj yeem tshem tawm qib ob lub zog loj tshaj: nws txoj kev lag luam- ua qis -kub los tiv thaiv corrosion. Muaj ntawv pov thawj raws li JIS G 3114: 2022 rau kub- dov atmospheric corrosion-resistant welded steels, SMA400CW yog engineered rau hnyav frigid, industrial, thiab ntug dej hiav txwv ib puag ncig. Nws cov kev cai txias txias tsis yog cov txheej txheem steel ua haujlwm dav dav; lawv yog cov khoom siv-tshwj xeeb, JIS- ua raws cov kev coj ua tsim los khaws nws cov qauv kev ncaj ncees, ductility, thiab ntev - kev ua tau zoo nyob rau hauv cov kev xav tau nws tau tsim los tiv thaiv.
JIS G 3114: 2022 Formability Baseline rau SMA400CW
SMA400CW lub peev xwm txias txias yog tsim ncaj qha rau hauv nws JIS-mandated chemical thiab mechanical specifications, uas teem nws sib nrug los ntawm cov qauv SMA400 series qib:
Ib qho ultra- cov ntsiab lus carbon tsawg tshaj plaws ntawm 0.12% txo qis ua haujlwm tawv thiab brittleness thaum khoov, thaum khaws cia cov hlau weldability
Qhov tsawg kawg nkaus elongation ntawm 22-26% (thickness-dependent) muab ductility zoo ib yam rau shaping yam tsis muaj fracturing
0.20-0.60% npib tsib xee ntxiv refines cov hlau cov qauv nplej, kom nws khaws nws -20℃cuam tshuam toughness txawm tias tom qab txias txias
Tightened impurity txwv (P Tsawg dua los yog sib npaug rau 0.030%, S Tsawg dua los yog sib npaug rau 0.030%) tiv thaiv ntug kev tawg thiab kev ntxhov siab hauv zos tsis ua haujlwm thaum thiab tom qab tsim
Cov qauv no ua rau SMA400CW sib haum nrog txhua txheej txheem txheej txheem txias txias, suav nrog nias braking, yob txoj kev, dabtsi yog khoov, thiab stamping, nrog rau cov kev cai calibrated los tiv thaiv nws cov cim hnyav heev -kev ua haujlwm ib puag ncig.
Tsis yog-JIS sib tham tau-Txhais yam tsawg kawg nkaus Khoov Radius Cov Cai
Ib txoj cai tseem ceeb tshaj plaws rau kev ua raws li kev ua kom txias txias yog ua raws li qhov tsawg kawg nkaus hauv kev khoov lub vojvoog, uas tiv thaiv micro- tawg uas tuaj yeem ua rau tawg tawg hauv qhov kub qis thiab cuam tshuam cov hlau tiv thaiv patina. Raws li JIS G 3114: 2022, nrog kev taw qhia ntxiv rau SMA400CW qhov txias- kev xav tsim huab cua:
1.5 × cov khoom thickness (t)rau cov ntawv tsawg dua lossis sib npaug ntawm 10mm tuab (JIS yam tsawg kawg nkaus yuav tsum tau); 2.0 × t lub vojvoog pom zoo rau cov qauv tsim rau kev tiv thaiv kom ruaj khov hauv qab -10 degree, kom txo qis kev ntxhov siab
2.0×trau nplooj ntawv 10-20mm tuab; 2.5 ×t pom zoo rau sub-zero daim ntawv thov
2.5×t for sheets >20mm tuab; 3.0 ×t pom zoo rau txias - huab cua hnyav siv cov qauv
Rau kev sib txuas txuas ntxiv los yog loj- vojvoog nkhaus, yuav tsum muaj 3.0 × t lub vojvoog yam tsawg kawg nkaus kom tswj tau qhov sib txawv ntawm kev ntxhov siab thoob plaws hauv seem tsim.
Ua ntej-Forming Preparation for JIS Compliance & Defect Prevention
Kev tsim nyog ua ntej- cov kauj ruam ua kom tshem tawm 80% ntawm cov kab mob khaub thuas ua tsis tau zoo, nrog rau cov kev xav tau ua kom haum rau SMA400CW qhov hnyav-cov ntaub ntawv siv ib puag ncig:
Ntug npaj: Deburr and smooth all sheared or cut edges along the bend line, especially for sheets >12mm tuab. Jagged npoo tsim cov ntsiab lus kev ntxhov siab uas nthuav mus rau hauv cov kab nrib pleb hauv qhov txias txias, txawm tias nyob rau hauv qhov tsawg kawg nkaus khoov vojvoog cov lus qhia.
Kev tiv thaiv kab mob: Tsis txhob sib cuag nrog cov cuab yeej carbon steel, cov chaw ua haujlwm, lossis cov khoom seem. Txawm tias me me hlau residues ua rau galvanic pitting corrosion, uas cuam tshuam cov hlau npib tsib xee- txhim khu kev tiv thaiv patina hauv kev lag luam lossis ntug hiav txwv ib puag ncig. Siv cov hlau tsis muaj steel lossis txhuas cov cuab yeej rau txhua txoj kev ua.
ambient kub tswj: Tsuas yog ua kom txias txias ntawm ambient kub Ntau dua lossis sib npaug li 5℃(41℃F). Thaum SMA400CW yog engineered rau sub- xoom kev pab cuam, tsim nyob rau hauv los yog qis dua qhov khov yuav txo nws cov ductility, ua rau muaj kev pheej hmoo ntawm zais micro- tawg uas tuaj yeem ua tsis tau tom qab txias- huab cua siv.
Hauv - Txheej Txheem & Tshaj Tawm - Tsim Cov Kev Ua Kom Zoo Rau Kev Ua Haujlwm Zoo
Cov JIS-cov kauj ruam ua raws kom ntseeg tau tias SMA400CW khaws nws cov kos npe qis- kub toughness thiab corrosion kuj tom qab tsim:
Khoov orientation alignment: Kho cov kab khoov kab perpendicular (ntawm qhov tsawg kawg yog 45℃kaum sab xis) rau cov hlau dov kev taw qhia. Khoov thaum uas tig mus rau dov kev taw qhia ua rau muaj kev pheej hmoo ntawm ntug kev tawg thiab txo cov seem tsim cov kev cuam tshuam toughness nyob rau hauv txias txias.
Tib - dhau qhov tseem ceeb ntawm kev tsim: Tsis txhob rov khoov dua qub lossis rov ua dua qub. Kev sib sau ntau dhau ua rau kev ua haujlwm ntau dhau, uas txo cov hlau ductility thiab tuaj yeem ua rau nws -20℃cuam tshuam kev ua haujlwm hauv qab JIS cov cai.
Tsis muaj kev tshaj tawm tsis tsim nyog - kev kho cua sov: Raws li JIS G 3114: 2022, kev ntxhov siab- kev kho cua sov tsis tas yuav tsum tau ua rau txias- tsim SMA400CW ntu hauv cov ntawv thov txheem. Kev kho cua sov tsis raug tuaj yeem cuam tshuam cov hlau cov qauv nplej, txo nws qhov qis - kub toughness thiab corrosion kuj.
Maj mam kho nto: Yog hais tias me me khawb los yog cov cuab yeej cim tshwm sim thaum lub sij hawm tsim, ntxuav lub cheeb tsam tsuas yog ib tug mos stainless hlau bristle txhuam. Tsis txhob sib tsoo hnyav, uas strips cov hlau alloy- nplua nuj txheej txheej thiab txo qhov ntev - lub sij hawm corrosion kuj.
Tseem ceeb yuam kev kom zam
Siv lub vojvoog khoov me dua li JIS yam tsawg kawg nkaus, txawm tias cov ntawv nyias nyias
Ua kom txias txias hauv qhov txias txias yam tsis muaj kev tswj hwm preheating
Rov ua dua cov txheej txheem tsim kho kom haum, uas ua rau kev ua haujlwm tsis zoo
Tso cai rau cov pa roj carbon monoxide rau ntawm cov khoom nto
Siv cov ntawv tshaj tawm- ua kev kho cua sov yam tsis muaj engineering validation rau cov ntawv thov txias heev
Hauv luv luv, JIS- ua raws cov kev coj ua txias txias rau SMA400CW Corten Steel yog tsim los ua ntau dua li cov khoom siv xwb-lawv tiv thaiv qib qhov hnyav hnyav -kev ua haujlwm ib puag ncig. Los ntawm kev ua raws li cov lus qhia no, cov neeg tsim khoom tuaj yeem tsim cov khoom siv kev cai uas khaws cov hlau tag nrho cov qauv kev ncaj ncees, qis- qhov kub thiab txias, thiab corrosion tsis kam rau ntau xyoo ntawm kev pabcuam txhim khu kev qha.
