Fang Gang:Nws yog khoom, bar khoom. Sib txawv ntawm lub raj square, lub raj hollow belongs rau lub raj. Hlau (Steel): Nws yog cov khoom siv nrog ntau yam duab, qhov ntau thiab tsawg thiab cov khoom xav tau los ntawm steel ingots, billets lossis steel los ntawm kev ua haujlwm siab. Hlau yog cov khoom tseem ceeb tsim nyog rau kev tsim kho hauv tebchaws thiab kev ua tiav ntawm plaub qhov kev hloov kho tshiab. Nws yog dav siv thiab muaj ntau yam khoom siv. Raws li cov duab sib txawv, cov hlau feem ntau muab faib ua plaub pawg: profiles, daim hlau, cov kav dej thiab cov khoom hlau. Txhawm rau kom yooj yim rau lub koom haum ntawm kev tsim steel, Kev txiav txim siab thiab ua haujlwm zoo ntawm kev tswj hwm kev ua haujlwm, muab faib ua cov tsheb ciav hlau hnyav, lub teeb rail, loj seem steel, nruab nrab seem steel, me me steel, txias-tsim steel seem steel, high- zoo seem steel, hlau pas nrig, nruab nrab thiab tuab steel phaj, nyias steel phaj, silicon steel ntawv rau hluav taws xob engineering, sawb steel, seamless steel yeeb nkab, welded steel yeeb nkab, hlau khoom thiab lwm yam ntau yam.
Steel tube puab:round, oval, square, rectangular
Txias kos square steel
Cold-drawn square steel yog hais txog txias-daws steel nrog square forging zoo
Cold-drawn square steel yog hais txog square txias-draw steel,
Cold-drawn steel yog yuam kom ncab lub steel bar nyob rau hauv ib txwm kub tej yam kev mob nrog ib tug tensile kev nyuaj siab uas tshaj qhov qub yield point lub zog ntawm steel bar, thiaj li hais tias lub steel bar yuav tsum plastically deformed mus cuag lub hom phiaj ntawm nce lub zog taw tes. ntawm steel bar thiab txuag steel.
Cold-drawn steel yog siv cov tshuab txias extrusion los rub tawm ntau yam high-precision, du-nto puag ncig steel, square steel, ca steel, hexagonal steel thiab lwm yam tshwj xeeb zoo li cov hlau los ntawm cov pwm meej.
Lub tswv yim ntawm txias-draw steel bars: rau lub hom phiaj ntawm kev txuag hlau thiab txhim kho lub zog ntawm cov hlau tuav, txoj kev ntawm stretching steel tuav nrog ib tug tensile kev nyuaj siab uas tshaj lub yield zog tab sis yog tsawg tshaj li qhov kawg lub zog ua rau cov yas deformation. yog hu ua txias-draw steel tuav.
Stainless hlau square hlau
Stainless hlau square hlau
[square steel] dov los yog ua tiav rau hauv ib qho square
Stainless hlau square hlau
Stainless hlau square steel feem ntau yog siv rau kev kho kom zoo nkauj, xws li lub qhov rooj thiab qhov rais.
Kev suav ntawm theoretical steel hnyav
Chav tsev ntawm kev ntsuas rau xam qhov theoretical hnyav ntawm steel yog kilogram (kg).
Cov mis mos yog: W (qhov hnyav, kg) = F (hli-sectional cheeb tsam mm2) × L (ntev, m) × ρ (density, g / cm3) × 1/1000
