Ib qho teeb meem ntawm lub kaum sab xis steel qauv qauv thiab cov ntawv thov

Angle steel, also known as angle iron, is a commonly used steel material with an L-shaped cross-section. Nws yog tsim kev tshwj xeeb los ntawm ob lub pob dej sib dhos nrog sib npaug lossis sib npaug ntawm cov dov lossis vuam. Nws cov qauv yooj yim thiab zoo {{{{{{}}} Txhais tawm cov khoom siv ua kom nws ua cov haujlwm Irreplaceist hauv teb xws li kev tsim kho, tshuab tsim khoom, thiab muaj zog engineering. Cov kab lus no qhia txog kev faib tawm, cov khoom siv, cov txheej txheem ntau lawm, thiab cov ntaub ntawv raug ntawm lub kaum sab xis steel.
I. Lub kaum sab xis steel faib tawm thiab cov txheej txheem tshwj xeeb
Lub kaum steel tuaj yeem muab faib ua ob pawg raws li ob sab ntawm ob sab (nrog sib npaug} Sib npaug - ceg} ceg} ceg ob tog yog feem ntau qhia tias yog "dav x thickness" (piv txwv li, 50mm). Feem ntev ntev los ntawm 20mm rau 200mm, thiab thicknesses ntau los ntawm 3mm txog 20 hli. Tsis ncaj - ceg} ceg ntev ntev (piv txwv li ntawm ib sab ntev ntawm 80mm, ib sab luv ntawm 50mm, thiab ib qho tuab ntawm 6 hli). Hauv International txheem txheej txheem, Tuam Tshoj Adjects GB / T 706 {{{} {}}}}}}}} Cov kev sib tw rau lub kaum sab xis steel. EU EN 10056 tus qauv tsom rau cov khoom siv neeg txhua qib, thaum peb Asmeskas ATM A6 / A6M qhia meej cov khoom yuav tsum muaj rau cov kev xaiv sib txawv. Muaj cov khoom lag luam tshwj xeeb (xws li lub nkoj roj (xws li siv hluav taws xob-}}}} _ malvanized anti-corrosion lub steel.

 

Ii. Cov Khoom Siv Khoom Siv Thiab Cov Kho Tshuab

Lub kaum sab xim qub yog feem ntau ua los ntawm cov roj carbon ua hlau (xws li Q235b thiab Q355B) lossis qis - lub zog steel. Nws cov tub ntxhais ua haujlwm tau cuam tshuam hauv peb yam:

1. Load - bearing muaj peev xwm

L - Daim ntawv zoo li cov ntu muaj txiaj ntsig zoo hauv kev tsoo txhav txhav. Nrog rau kev teeb tsa kom zoo, lawv tuaj yeem ua ke nrog ua kom axial compression, shear, thiab sib xyaw ua ke. Piv txwv li, lub compressive lub zog ntawm qhov sib npaug- ceg} ceg dav hlau tuaj yeem tshaj 1.8 lub sij hawm uas ntawm cov hlau hloov pauv {{5 5 5 5}}

Yooj yim ntawm kev sib txuas: nws cov npoo ncaj thiab yooj yim kom ua tiav cov kev sib dhos ua ke los ntawm kev sib dhos ua ke los ntawm kev sib dhos ua ke los ntawm kev sib dhos ua ke los ntawm kev sib dhos ua ke los ntawm kev sib dhos ua ke los ntawm kev sib dhos ua ke los ntawm kev sib dhos.

3.economical: piv rau kev cai - shape steel muaj cov khoom siv ntau dua 5%) thiab cov nqi qis.

Kev sim cov ntaub ntawv qhia tau hais tias Elastic Modulus of Q35B tsis sib xws}, tag nrho cov qauv tsim nyog los yog sib luag ntawm 56 4} {{5} {qhov chaw muaj zog.

 

 

III. Cov Txheej Txheem Txheej Txheem Ntau Lawm
Niaj hnub nimno lub qub steel manufacturing feem ntau ntawm kev nruam kub dov. Cov txheej txheem ib txwm muaj xws li:
• Kev npaj seem dawb: Cov khoom siv tshuaj pov tseg tsis tu ncua (mn tsawg dua lossis sib npaug lossis muaj sib npaug nrog rau 0.00-1250℃muaj peev xwm yooj yim;
• Dov: multi -}}}}}}} {{1} Tus ntoo khaub lig zoo nkauj-}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}. Qhov kawg dov qhov kub yog tswj nruab nrab ntawm 850-950℃kom ntseeg tau tias cov qoob loo zoo;
• Ncej {-} Ua: Qhov no suav nrog kev dag kom zoo dua (thooj), thiab kev dag kom zoo (
Rau lub kaum ntse ntse rau cov ntawv thov tshwj xeeb (xws li lub zog hluav taws xob tshwj xeeb), cov kauj ruam kev tswjhwm zoo xws li kev sim thev naus laus zis yuav tsum muaj.

 

IV. Kev tsom xam ntawm cov ntaub ntawv raug cai
(Kuv) tsim kev tsim kho
Raws li kev txhawb nqa cov txheej txheem ntawm cov qauv qauv, lub kaum sab xis siv hauv cov qauv hlau sib txuas, cov neeg saib xyuas cov choj, thiab cov seismic txhawb cov tshuab rau high}}} Rose tsev. Piv txwv li, cov pob qij txha truss ntawm Shanghai ntauwd siv Q345GJ High- Lub kaum ntse ntse lub steel kom ua tiav kev tsim hnav.
(II) Hwj chim thiab kev sib txuas lus infrastructure
Kev Hloov Chaw thiab cov txheej txheem hloov cia siv rau ntawm cov loj-}}}} Cov ntaub ntawv qhia tau hais tias kub - dip galvanizing lub qub hlau tuaj yeem txuas nws txoj kev pabcuam sab nraud dhau 30 xyoo.
(III) Machinery Raug
Tsis ncaj - legged lub kaum steel feem ntau siv los ua kom pom kev ntxhov siab hauv cov khoom sib txuas thiab crane boom kev sib txuas daim hlau. Finite calter of boom qauv ntawm qee cov qauv qauv excavator pom tau hais tias qhov tsim nyog kev teeb tsa ntawm lub kaum sab xis ntawm lub cev muaj txiaj ntsig txog 22%.

Lub kaum ntse ntse, nrog nws cov qauv geometry, cov cuab yeej txhim khu kev qha, thiab paub tab tau muab cov khoom siv rau cov khoom siv rau niaj hnub no. Nrog rau kev txhim kho cov vaj tse ntsuab thiab cov khoom muaj tswv yim ntse yuav hloov kho siab, kev tiv thaiv corrosion} {1} {}} cov yam ntxwv nyob rau yav tom ntej. Nyob rau tib lub sijhawm, nrog lub zog ntawm cov thev naus laus zis xws li cov qauv digital thiab 3D luam tawm kev tsim, lawv thaj tsam ntawm lawv thaj tsam hauv cov txheej txheem nyuaj yuav txuas ntxiv mus ntxiv.
