Hauv kev tsim kho thoob ntiaj teb, kev tsim kho vaj tse, thiab kev lag luam tshuab hnyav, Rectangular Hollow Sections (RHS) yog cov khoom siv tseem ceeb. Txawm li cas los xij, thaum tus thawj tswj hwm kev yuav khoom thiab cov kws tsim khoom tsim qauv tsim RHS, lawv ntsib qhov kev xaiv tsim khoom tseem ceeb:Kub Tiav lawmpivTxias tsim.
Thaum lub caij txias-cov hlau ua cov hlau tau dav dav rau lub teeb- ntsuas kev siv, cov txheej txheem hnyav hnyav hnyav hnyav hnyav, siab compression, thiab huab cua hloov pauv ib puag ncig xav tau cov khoom siv hlau zoo dua. Cov ntaub ntawv kev lag luam thoob plaws no tshawb nrhiav vim li cas kub ua tiav RHS sawv ua tus qauv hwm rau siab - kev ntxhov siab engineering, kev tshawb fawb tshuab ua haujlwm tom qab nws qhov kev ua tau zoo, thiab cov chaw tsim khoom thoob ntiaj teb zoo li cas Hlau Hlau xa cov ntawv pov thawj kev daws teeb meem rau cov haujlwm thoob ntiaj teb.
Qhov txawv ntawm Kub Tiav thiab Cold tsim RHS yog dab tsi?
Qhov txawv ntawm Kub Tiav thiab Cold tsim RHS yog dab tsi?
Qhov sib txawv ntawm qhov kub tiav thiab txias tsim hollow seem nyob rau hauv lawv qhov kub thiab txias profile profiles:
- Cold tsim RHS:Tsim los ntawm kev siv lub tiaj tus steel kauj ntawm chav tsev kub, tsis tu ncua khoov nws los ntawm cov txheej txheem ntawm cov chais rau hauv cov duab plaub, thiab vuam cov seam ntev. Vim tias cov hlau raug yuam kom ua kom zoo thaum lub caij txias, qhov kev ntxhov siab loj hauv cov seem raug kaw hauv cov ces kaum ntawm ntu.
- Kub tiav RHS:Tsim los ntawm cov txheej txheem uas cov hlau seem tau ua tiav nws qhov kawg shaping lossis kev kho cua sov ntawm qhov ntsuas kub ib txwm muaj -feem ntau tshaj 850℃txog 900℃. Qhov kub siab heev no hloov pauv cov qauv crystalline ntawm cov hlau, tshem tawm cov kev ntxhov siab uas seem thiab rov ua kom zoo ib yam, homogeneous microstructure thoob plaws lub ntsej muag tiaj tus thiab cov fab xwm yeem.
Vim li cas Qhov Tsis Muaj Kev Nyuaj Siab Uas Tsis Muaj Teeb Meem Hauv Cov Khoom Siv Hnyav?
Vim li cas Qhov Tsis Muaj Kev Nyuaj Siab Uas Tsis Muaj Teeb Meem Hauv Cov Khoom Siv Hnyav?
Thaum cov hlau ua kom txias yog khoov ntawm chav tsev kub, cov ces kaum raug mob hnyav hauv zos txias- ua haujlwm. Qhov no ua rau cov neeg kho tshuab tsis muaj qhov tsis zoo:
- Inconsistent Strength Profiles:Nyob rau hauv ib qho txias - tsim RHS, lub zog yields nce nyob rau hauv cov ces kaum vim strain hardening, tab sis cov ductility poob qis heev. Yog tias seem raug hloov kho cov qauv hnyav-xws li kev sib tsoo, kub-dip galvanizing, lossis beam-rau-kem sib koom-cov siab no- cov cheeb tsam kev ntxhov siab yog qhov ua rau micro- cracking thiab brittle tsis ua hauj lwm.
- Predictable Stress Distribution:Kub tiav RHS los ntawm advanced mills nyiamHlau Hlauyog kev ntxhov siab tag nrho-relief annealed. Vim hais tias cov hmoov nplej siv lead ua recrystallize uniformly, cov khoom siv kho tshuab zoo ib yam thoob plaws tag nrho cov ntoo khaub lig -section. Cov kws tsim qauv tsim qauv tuaj yeem muab cov lej suav tseeb rau hauv kev tsim software yam tsis muaj kev cuam tshuam hauv cov txheej txheem tsis muaj zog hauv cov ces kaum.
Yuav Ua Li Cas Tight Dimensional Tolerances thiab Sharp Corners Optimize Building Fit-Up?
Hauv kev tsim cov txheej txheem steelwork, lub sijhawm ntawm -qhov chaw txhais ncaj qha rau cov nqi tsim khoom. Lub cev profile ntawm kub tiav RHS muaj cov txiaj ntsig geometric tseem ceeb tshaj qhov txias - tsim lwm txoj hauv kev:
- Thicker thiab Sharper Radii:Txias- cov seem tsim yuav tsum muaj qhov loj, sib npaug sab nraud lub kaum sab xis kom tiv thaiv cov hlau tsis sib cais thaum lub caij txias txias. Kub tiav RHS nta nruj, ntse, thiab zoo ib yam kaum profiles. Qhov no ua rau thaj chaw tiaj tus siv tau zoo rau ntau -axis txuas daim hlau.
- Uniform Phab Ntsa Thickness:Kev ua tiav kub ua kom muaj qhov sib xws ntawm phab ntsa tuab thiab tshem tawm "tawm- ntawm- roundness" lossis twisting raws qhov ntev ntawm ntu. Qhov siab qhov tseeb qhov tseeb no lav kev sib khi tsis sib haum thaum lub sijhawm siv lub tshuab orbital vuam lossis phau ntawv ntsia hlau- cov txheej txheem nce.
Vim li cas Kub Tiav RHS muaj kev nyab xeeb dua rau av qeeg, Dynamic vibrations, thiab Arctic txias?
Cov qauv zoo li ntau-cov dab neeg skyscrapers, offshore roj platforms, cov neeg taug kev overpasses, thiab hnyav-cov haujlwm crane khiav yog raug rau kev qaug zog tsis tu ncua- mus txuas ntxiv ntawm kev vibration, hloov, thiab cua deflection.
- High Fracture Toughness:Kub tiav steel exhibits zoo heev tej yam kuj thiab puas toughness. Cov cuab yeej no tiv thaiv me me nto khawb los yog micro- pores los ntawm tam sim ntawd nthuav tawm mus rau hauv cov kab nrib pleb loj hauv kev ntxhov siab.
- Resilience rau qis-Tub kub brittle Failure:Ntawm sub- xoom kub, cov qauv hlau ua nkig thiab tuaj yeem ua rau muaj kev cuam tshuam tam sim ntawd. Kub tiav RHS tuav nws cov ductility thiab siab Charpy V-notch (CVN) cuam tshuam rau lub zog muaj nuj nqis ntawm qhov kub thiab txias li -20℃lossis -46 degree, ua rau nws yog qhov kev xaiv nyab xeeb tshaj plaws rau huab cua caij ntuj no hnyav lossis thaj tsam seismic.
Kub Tiav RHS puas tuaj yeem tshem tawm cov kua hlau embrittlement txaus ntshai thaum galvanization?
Rau cov qauv hlau raug rau sab nraud ya raws, ntug hiav txwv ntsev huab cua, los yog muaj tshuaj, kub-dip galvanizing yog qhov nyiam los tiv thaiv- kev kho corrosion. Txawm li cas los xij, dipping steel rau hauv molten zinc ntawm kwv yees li $ 450^\\circ\\text{C}$ qhia txog kev pheej hmoo metallurgical.
- Qhov Txias -Tsim Risk:Cov kub kub ntawm cov zinc da dej tuaj yeem ua rau muaj kev ntxhov siab - hnub nyoog embrittlement nyob rau hauv siab - kev ntxhov siab ntawm qhov txias txias - tsim RHS, ua rau seem tawg spontaneously thaum lub sij hawm los yog sai tom qab galvanizing.
- Kub Finished Assurance:Vim tias kub ua tiav RHS tsis muaj qhov cuam tshuam ntawm kev tsim khoom, nws tuaj yeem kub -dip galvanized ntau zaus yam tsis muaj kev pheej hmoo ntawm Liquid Metal Embrittlement (LME) lossis qhov txawv txav, lav ntau xyoo ntawm xeb- lub neej kev pab dawb.
