Cold Drawn Tshwj Xeeb-Shaped Steel
Vim tias qhov tshwj xeeb thiab qhov sib txawv ntawm nws txoj kev siv, cov hlau tshwj xeeb feem ntau muaj cov kev xav tau siab dua rau qhov tseeb dua li cov hlau yooj yim, uas muaj cov kev xav tau siab dua ntawm cov khoom siv. Vim hais tias ntawm nws txoj kev hla ntu zoo, tshwj xeeb tshaj yog cov hlau zoo li tshwj xeeb rau ntau lub sijhawm tshwj xeeb, muaj kev paub me ntsis los ntawm kev kawm, uas ua rau dhau kev tsim thiab kev tsim khoom nyuaj dua li qhov yooj yim cross-section steel. Yog li ntawd, cov nqi tsim khoom ntawm cov hlau tshwj xeeb yog siab dua li ntawm cov hlau yooj yim-section. Vim tias qhov sib txawv loj ntawm cov duab thiab qhov loj me ntawm cov hlau tshwj xeeb, ntau ntawm lawv tau mob siab rau qee yam kev lag luam lossis qee lub sijhawm, yog li kev lag luam xav tau rau ib qho ntau yam feem ntau tsis loj heev. Yog li ntawd, qhov ntsuas ntawm qhov tshwj xeeb-zoo li steel ntau lawm system feem ntau tsis loj heev.
Tshwj xeeb-zoo li tus steel yog lub ntsiab lus ntawm complex thiab tshwj xeeb-zoo li tus seem steel, uas belongs rau ib hom ntawm seem steel, thiab yog txawv los ntawm lub npe ntawm yooj yim seem steel. Raws li cov txheej txheem sib txawv, nws tuaj yeem muab faib ua kub dov tshwj xeeb-zoo li steel, txias-draw (txias-draw) tshwj xeeb-zoo li steel, txias-tsim tshwj xeeb-zoo li tus hlau, welded tshwj xeeb-puab steel, thiab lwm yam. Feem ntau tshwj xeeb- zoo li tus hlau yog hais txog kub-dov tshwj xeeb-zoo li tus hlau. Kub-dov tshwj xeeb-zoo li tus steel yog ib tug kub-kuav los tiag steel uas txawv square steel, round steel, ca hlau thiab ntau hom.
Vim tias qhov tshwj xeeb thiab qhov sib txawv ntawm nws txoj kev siv, cov hlau tshwj xeeb feem ntau muaj cov kev xav tau siab dua rau qhov tseeb dua li cov hlau yooj yim, uas muaj cov kev xav tau siab dua ntawm cov khoom siv. Vim hais tias ntawm nws txoj kev hla ntu zoo, tshwj xeeb tshaj yog cov hlau zoo li tshwj xeeb rau ntau lub sijhawm tshwj xeeb, muaj kev paub me ntsis los ntawm kev kawm, uas ua rau dhau kev tsim thiab kev tsim khoom nyuaj dua li qhov yooj yim cross-section steel. Yog li ntawd, cov nqi tsim khoom ntawm cov hlau tshwj xeeb yog siab dua li ntawm cov hlau yooj yim-section. Vim tias qhov sib txawv loj ntawm cov duab thiab qhov loj me ntawm cov hlau tshwj xeeb, ntau ntawm lawv tau mob siab rau qee yam kev lag luam lossis qee lub sijhawm, yog li kev lag luam xav tau rau ib qho ntau yam feem ntau tsis loj heev. Yog li ntawd, qhov ntsuas ntawm qhov profiled steel ntau lawm feem ntau tsis loj heev.
Sectional steel yog ib qho ntawm plaub hom hlau loj (zoo li tus, hlau, phaj, thiab raj), thiab nws yog cov hlau siv dav. Raws li cov duab seem, seem steel yog muab faib ua ntu yooj yim seem steel thiab complex los yog tshwj xeeb seem steel (special-shaped steel). Tus yam ntxwv ntawm tus qub yog tias tangents ua nyob rau hauv ib qho chaw ntawm lub periphery ntawm tus ntoo khaub lig seem feem ntau tsis sib tshuam nyob rau hauv seem. Xws li: square steel, round steel, ca steel, kaum steel, hexagonal steel, thiab lwm yam .; Cov hlau tshwj xeeb uas muaj xws li kub dov qhov rais thav duab steel, ploughshare steel, kub dov seem steel rau tsheb log tuav rings, kub dov seem hlau rau cov phiaj, thiab tsheb log rims. Kub dov seem steel, steel rail, tiaj pob steel rau nkoj tsim, cable coil steel, scraper steel, thiab lwm yam.
