Thaum xaiv SPA-H Corten Steel (JIS G 3125 tus qauv) rau cov haujlwm uas muaj qhov kub thiab txias los yog hluav taws kub nyhiab-xws li cov chaw tsim khoom siv hluav taws xob, cov chaw tsim hluav taws xob, lossis siab- nce lub tsev cov khoom- cov khoom tuab li cas cuam tshuam nws lub peev xwm tiv taus cua sov thiab tswj kev ua haujlwm hauv hluav taws? Lo lus nug no ncaj qha ntsig txog kev nyab xeeb ntawm cov qauv thiab kev tsim qauv tsim nyog. Cia peb ua kom meej meej:SPA-H tuab zoo cuam tshuam nws qhov siab - qhov kub thiab txias tiv taus, tab sis cov nyhuv ua raws li cov cai tshwj xeeb. Hauv qab no yog ib qho kev ntsuam xyuas me me thiab cov lus qhia siv tau.
1. Muaj feem cuam tshuam rau siab -Tsub Resistance: Thickness Enhances Thaum tshav kub kub rwb thaiv tsev & Lub zog tuav
Siab -kub tsis kam ntawm no yog hais txog cov khoom muaj peev xwm khaws cov khoom siv kho tshuab (lub zog, ductility) thaum raug kub siab (200-600℃). Thickness cuam tshuam qhov no feem ntau los ntawm kev hloov hluav taws xob thiab kev ntxhov siab sab hauv:
Thaum tshav kub kub rwb thaiv tsev nyhuv: Thicker SPA-H nplooj ntawv muaj cov thermal inertia zoo dua-lawv nqus thiab hloov cua sov qeeb dua. Piv txwv li, ntawm 500℃, 10mm-Tick SPA-H daim ntawv khaws cia ~ 45% ntawm nws chav- kub tawm lub zog (Ntau dua lossis sib npaug rau 345MPa), thaum 5mm{11}} daim ntawv tuab tsuas khaws tau ~ 35%. Lub thickness ntawm cov khoom tseem ceeb nyob twj ywm txias rau ntev, ncua lub zog degradation.
Kev nyuaj siab: Thinner SPA-H (tsawg dua lossis sib npaug li 6 hli) yog qhov yooj yim rau thermal deformation ntawm qhov kub thiab txias vim qhov qis dua cov qauv. Cov nplooj ntawv tuab (Ntau dua lossis sib npaug li 8 hli) tuaj yeem tiv taus kev ntxhov siab zoo los ntawm qhov kub thiab txias, txo qhov kev pheej hmoo ntawm kev sib tsoo lossis tawg.
Cov ntsiab lus tseem ceeb: Txawm hais tias thickness, SPA-H siab- qhov kub thiab txias ua haujlwm siab tshaj 550 degree. Ntxiv rau qhov no, nws lub zog poob qis heev (rau<50% of room temperature strength), and thickness can only slightly mitigate this decline.
2. Kev cuam tshuam rau hluav taws kev ua haujlwm: Thickness Extends Fire Endurance Time
Kev ua tau zoo ntawm hluav taws yog ntsuas los ntawm lub sij hawm tiv thaiv hluav taws - lub sijhawm ntawm cov khoom siv tuav cov khoom thauj - cov kabmob muaj peev xwm raws li tus qauv hluav taws kub (raws li ASTM E119 lossis EN 13381). Rau SPA-H, thickness yog qhov txiav txim siab nyob rau lub sijhawm no:
Txoj Cai: Thicker SPA-H=Kev tiv thaiv hluav taws ntev dua. Cov ntaub ntawv qhia tau hais tias: 6mm-Tick SPA-H muaj qhov hluav taws kub ntawm ~ 15 feeb; 10mm-tuab=~ 30 feeb; 15mm -tuab=~ 45 feeb. Qhov no yog vim tus ntoo khaub lig thicker-section yuav siv sij hawm ntau dua rau qhov hluav taws kub cua nkag mus rau hauv lub hauv paus, ncua qhov poob ntawm load{17}}cov kabmob muaj peev xwm.
Txwv ntawm Thickness Effect: Thaum thickness tshaj 20mm, qhov nce ntawm hluav taws kub endurance yuav negligible. Piv txwv li, 20mm- ntawv tuab muaj qhov hluav taws kub ntawm ~ 55 feeb, thaum 25mm- daim ntawv tuab tsuas yog txuas mus rau ~ 60 feeb. Ntxiv rau qhov no, nce thickness muaj txiaj ntsig me ntsis tab sis nce cov khoom siv thiab cov nqi tsim kho.
Kev xaiv tswv yim & cov lus qhia siv
Targeted Thickness Xaiv: Rau qis- kub kub- cov khoom raug (200-300℃, xws li cov kab hluav taws xob ua haujlwm), 6-8mm SPA-H txaus. Rau cov xwm txheej kub ntxhov (300-500 degree, piv txwv li, cov khoom siv hluav taws xob hluav taws xob) lossis cov qauv uas xav tau ntau dua lossis sib npaug li 30 feeb ntawm kev tua hluav taws, xaiv 10-15mm thickness.
Ua ke nrog kev tiv thaiv hluav taws rau cov qauv tseem ceeb: Txawm tias tuab SPA-H (Ntau dua lossis sib npaug li 15mm) tsis tuaj yeem ua tau raws li 60-120 feeb hluav taws kub hnyiab uas yuav tsum tau ua los ntawm cov cai hauv tsev feem ntau. Rau kev thauj khoom-cov kabmob hauv siab- cov tsev nce siab lossis cov chaw pej xeem, khub SPA-H nrog cov txheej txheem hluav taws kub tsis zoo (cov yeeb yaj kiab qhuav tuab 1.0-2.5mm) txhawm rau txuas hluav taws kub mus rau cov qauv xav tau.
Zam dhau -Thick Design: Tsis txhob ua qhov muag tsis pom kev ua kom tuab kom ua tau zoo dua - kub / hluav taws ua haujlwm. Rau cov xwm txheej xav tau kev tiv thaiv hluav taws ntev tshaj li 45 feeb, txheej txheej yog tus nqi ntau dua - zoo dua li cov khoom tuab.
Hauv cov ntsiab lus, SPA-H Corten Steel thickness muaj txiaj ntsig zoo rau nws qhov siab - qhov kub thiab txias kev ua tau zoo- cov ntawv tuab muab cov rwb thaiv tsev zoo dua, kev tuav lub zog ntev dua, thiab kev tiv thaiv hluav taws ntev dua. Txawm li cas los xij, cov nyhuv yog txwv siab tshaj 20mm. Xaiv qhov tuab tuab raws li qhov ntsuas kub thiab qhov xav tau ntawm hluav taws, thiab sib txuas nrog kev tiv thaiv hluav taws tsim nyog thaum tsim nyog, ua kom muaj kev nyab xeeb ntawm cov qauv thiab cov nqi tsim nyog.
