Hom hlau

 

Cov hlau uas yaj hauv lub cub tawg raug pov rau hauv cov hlau billets, thiab cov ingots lossis billets raug nias rau hauv hlau (cov khoom hlau). Muaj ntau hom hlau, uas feem ntau tuaj yeem muab faib ua plaub pawg: pwm, phaj, raj thiab xov hlau.

 

Tshooj hlau

Muaj ntau hom hlau seem, uas yog ib hom hlau ntev uas muaj qee yam duab thiab qhov loj ntawm cov hlau seem. Raws li cov duab sib txawv ntawm cov hlau seem, nws muab faib ua ob hom: cov seem yooj yim thiab cov seem nyuaj. Cov qub suav nrog cov hlau puag ncig, cov hlau plaub fab, cov hlau tiaj tiaj, cov hlau hexagonal thiab cov hlau kaum sab xis; Cov tom kawg suav nrog cov hlau ntsia hlau, I-beams, cov hlau channel, cov hlau thav duab qhov rai thiab cov hlau zoo li tshwj xeeb. Cov hlau puag ncig me me uas muaj txoj kab uas hla ntawm 6.5-9.0 hli hu ua hlau.

 

Cov phaj hlau

Nws yog ib hom hlau tiaj tiaj uas muaj qhov sib piv dav thiab tuab loj thiab thaj chaw saum npoo. Raws li qhov tuab sib txawv, nws muab faib ua peb hom: phaj nyias (tuab < 4 hli), phaj nruab nrab (tuab 4-25 hli) thiab phaj tuab (tuab > 25 hli). Cov hlau strips suav nrog hauv pawg phaj hlau.

 

Cov kav hlau

Nws yog ib daim hlau ntev nrog ib ntu hollow. Raws li nws cov duab sib txawv, nws tuaj yeem muab faib ua cov kav dej puag ncig, cov kav dej square, cov kav dej hexagonal thiab ntau yam yeeb nkab hlau tshwj xeeb. Raws li cov txheej txheem ua tiav sib txawv, nws tuaj yeem muab faib ua ob pawg: cov yeeb nkab hlau seamless thiab cov yeeb nkab hlau welded.

 

Cov xov hlau

Hlau hlau yog lwm yam khoom siv ua los ntawm hlau uas ua haujlwm txias. Raws li ntau yam duab, nws muab faib ua hlau hlau puag ncig, hlau hlau tiaj tus thiab hlau hlau peb ceg, thiab lwm yam. Ntxiv rau kev siv ncaj qha, hlau hlau kuj tseem siv rau hauv kev tsim cov hlua hlau, cov kab hlau thiab lwm yam khoom.

 

Lub kaum sab xis hlau

Cov hlau kaum sab xis, feem ntau hu ua hlau kaum sab xis, yog ib daim hlau ntev uas sib dhos rau ib leeg ntawm ob sab. Muaj cov hlau kaum sab xis sib npaug thiab cov hlau kaum sab xis tsis sib npaug. Ob sab ntawm lub kaum sab xis sib npaug dav sib npaug. Nws cov lus qhia tau qhia hauv millimeters ntawm qhov dav ntawm sab.× qhov dav ntawm sab× tuab ntawm ntug. Piv txwv li, "∠30×30×3", uas txhais tau tias qhov dav ntawm sab yog 30 hli thiab qhov tuab ntawm sab yog 3 hli. Nws kuj tseem tuaj yeem qhia los ntawm tus lej qauv, uas yog tus lej ntawm centimeters ntawm qhov dav ntawm sab, xws li∠3 #. Tus qauv tsis sawv cev rau qhov loj ntawm cov tuab sib txawv hauv tib tus qauv, yog li qhov dav thiab tuab ntawm cov hlau kaum sab xis tau sau rau hauv daim ntawv cog lus thiab lwm cov ntaub ntawv, kom tsis txhob siv tus qauv ib leeg. Cov lus qhia ntawm cov hlau kaum sab xis kub dov yog 2 # -20 #.　　

Cov hlau kaum sab xis tuaj yeem ua los ntawm ntau yam khoom sib txawv raws li qhov xav tau sib txawv ntawm cov qauv, thiab kuj tuaj yeem siv ua qhov txuas ntawm cov khoom. Nws yog dav siv hauv ntau yam qauv tsev thiab cov qauv engineering, xws li cov ntoo tsev, choj, cov pej thuam kis, cov tshuab nqa thiab thauj mus los, nkoj, cov cub tawg kev lag luam, cov pej thuam teb, cov txee thawv thiab cov txee rau khoom.

 

Hlau puag ncig

 

Cov hlau puag ncig yog hais txog cov hlau uas muaj ib daim hlau uas muaj ib lub voj voog. Nws cov lus qhia yog qhia ua millimeters ntawm txoj kab uas hla, piv txwv li "50" txhais tau tias yog ib daim hlau puag ncig uas muaj txoj kab uas hla ntawm 50 hli. Muaj peb hom hlau puag ncig: kub dov, forged thiab txias rub. Cov hlau puag ncig kub dov muaj nyob rau hauv qhov loj me ntawm 5.5 txog 250 hli. Ntawm lawv: 5.5-25 hli hlau puag ncig me me feem ntau muab ua cov kab ncaj, uas feem ntau siv ua cov hlau tuav, bolts thiab ntau yam khoom siv kho tshuab; cov hlau puag ncig loj dua 25 hli feem ntau yog siv los ua cov khoom siv kho tshuab lossis cov yeeb nkab hlau tsis muaj seamless.

 

Cov hlau txuas

Cov hlau rau cov pob zeb ua vaj tse yog hais txog cov hlau ncaj lossis cov hlau siv rau kev txhawb nqa cov pob zeb ua vaj tse, thiab nws cov duab yog muab faib ua ob hom: lub teeb puag ncig hlau bar thiab deformed hlau bar, thiab lub xeev xa khoom yog ncaj bar thiab disc puag ncig. Lub teeb puag ncig hlau bar yog qhov tseeb me me puag ncig hlau thiab disc voj voog ntawm cov hlau carbon qis ib txwm muaj. Cov hlau deformed bars yog ribbed hlau bars nrog ib qho chaw, feem ntau nrog 2 longitudinal tav thiab transverse tav sib npaug zos raws qhov ntev. Muaj peb hom transverse tav: spiral, herringbone thiab crescent. Nws yog qhia hauv millimeters ntawm nominal txoj kab uas hla. Lub nominal txoj kab uas hla ntawm deformed reinforcement yog sib npaug rau lub nominal txoj kab uas hla ntawm lub teeb puag ncig reinforcement nrog sib npaug cross-section. Lub nominal txoj kab uas hla ntawm cov hlau bar yog 8-50 hli, thiab lub pom zoo txoj kab uas hla yog 8, 12, 16, 20, 25, 32, 40 hli.　　

Cov hlau txhawb nqa feem ntau raug kev nyuaj siab tensile hauv cov pob zeb ua vaj tse. Vim yog qhov ua haujlwm ntawm cov tav, cov hlau deformed muaj peev xwm sib txuas nrog cov pob zeb ua vaj tse ntau dua, yog li nws tuaj yeem tiv taus qhov kev ua haujlwm ntawm lub zog sab nraud zoo dua. Cov hlau txhawb nqa yog siv dav hauv ntau yam qauv tsev, tshwj xeeb tshaj yog cov qauv tsev loj, hnyav, sib dua, phab ntsa nyias thiab cov qauv tsev siab.

 

Cov hlau channel

Cov hlau channel yog ib daim hlau ntev uas muaj ib qho grooved cross-section. Nws cov qauv sawv cev, xws li 120 * 53 * 5, qhia txog cov hlau channel uas muaj qhov siab ntawm 120 mm thiab ceg dav ntawm 53 mm, thiab cov hlau channel uas muaj qhov tuab ntawm 5 mm, lossis 12 # hlau channel. Yog tias muaj ntau qhov dav ntawm ceg thiab qhov tuab ntawm lub duav sib txawv, koj kuj yuav tsum ntxiv A, B, thiab C rau sab xis ntawm tus qauv kom paub qhov txawv ntawm lawv, xws li 25A #, 25B #, 25C #, thiab lwm yam. Cov hlau channel yog muab faib ua cov hlau channel ib txwm thiab cov hlau channel sib dua. Cov lus qhia ntawm cov hlau channel kub dov yog 5-40 #. Cov lus qhia ntawm cov hlau channel kub dov uas muab los ntawm kev pom zoo ntawm cov neeg muab khoom thiab cov neeg thov khoom yog 6.5-30 #.

Cov hlau channel feem ntau yog siv rau hauv cov qauv tsev, kev tsim tsheb thiab lwm yam qauv kev lag luam, thiab cov hlau channel feem ntau siv ua ke nrog I-beams.
