Hlau hlauthiab hlau hlau muaj ntau qhov zoo sib xws, tab sis ua tib zoo paub qhov txawv, koj yuav pom tias lawv tsis tsuas yog sib txawv ntawm cov khoom, tab sis kuj nyob rau hauv cov yam ntxwv ntawm cov khoom sib txawv heev.Yog li thaum xaiv, xyuas kom koj ua kom pom tseeb qhov txawv ntawm ob.Steel hlau Hoobkas qhia steel hlau carbon qauv steel ua los saum toj no, feem ntau tsis galvanized, siv rau machinery, caij nplooj ntoos hlav.Dub thiab tawv;Hlau hlau: qis carbon steel (mild steel), galvanized, siv rau kev sib koom thiab qhwv.Nws yog dawb thiab mos.
Qhov sib txawv tseem ceeb yog cov ntsiab lus carbon.Hlau muaj cov ntsiab lus carbon ntawm 2.11 feem pua lossis ntau dua, thaum hlau muaj cov ntsiab lus carbon ntawm 2.11 feem pua lossis tsawg dua.Hlau-carbon alloys nrog cov ntsiab lus ntawm ntau tshaj 2.11% yog cam khwb cia hlau (npua hlau), uas yog ib qho yooj yim tsis malleable thiab tsis tuaj yeem kos rau hauv hlau.Qhov thib ob, cov ntsiab lus ntawm impurities yog txawv, thiab cov ntsiab lus ntawm cov teeb meem impurities xws li sulfur thiab phosphorus hauv hlau yog me dua.Hlau xim xim tseem ceeb, hlau xim lub teeb taw tes, dawb taw tes.
Lub neej hais tias "xaim", qhov tseeb, yog "tsawg carbon steel hlau", cov ntsiab lus carbon hauv 0.2% hauv qab no.Qhov saum npoo feem ntau yog coated nrog zinc txheej vim nws yooj yim rau xeb.Nyob rau hauv atmospheric tej yam kev mob, galvanized txheej yuav tsis xeb ua ntej feem ntau ntawm lub caij nplooj zeeg tawm, kuj mos.Lub neej hais tias "steel hlau", yog cov ntsiab lus carbon ntawm li 0.6% ntawm "carbon steel hlau", los yog cov ntsiab lus carbon ntawm li 0.8% ntawm "high carbon steel hlau", lawv muaj txaus hardness thiab elasticity tom qab tsim nyog kho cua sov, siab zog.Kev siv cov lus xws li winding dog dig caij nplooj ntoos hlav thiab lwm yam.
Annealed hlau yog ib hom mos hlau hlau ua los ntawm cov pa roj carbon tsawg los ntawm kev kos duab txias, cua sov, qhov kub thiab txias thiab txuag hluav taws xob.Qhov sib xyaw ntawm cov hlau sib txawv raws li nws siv.Nws muaj hlau, cobalt, npib tsib xee, tooj liab, carbon, zinc, thiab lwm yam khoom.Cov hlau kub kub yog dov rau hauv 6.5 hli tuab steel bar, uas yog, cov hlau pas nrig, thiab tom qab ntawd nws muab tso rau hauv cov khoom siv hlau kos duab los kos cov hlau sib txawv, thiab maj mam txo qhov aperture ntawm daim duab disk, txias, annealing, plating thiab lwm yam kev siv tshuab ua kom muaj ntau yam sib txawv ntawm cov hlau.
Annealed hlauyog tsuas yog los ntawm cov pa roj carbon tsawg cua sov, kub daim duab, qhov kub thiab txias thiab lwm yam txheej txheem ua rau cov hlau mos hlau, vim hais tias nyob rau hauv kev siv sib txawv, yog li muaj ntau yam sib txawv nyob rau hauv cov txheej txheem ntau lawm, ua los ntawm ntau yam specifications.Annealed hlau tuaj yeem siv dav, feem ntau vim tias cov hlau annealed thiab lwm yam hlau hlau, muaj ntau yam zoo.
Kev tu thiab tu tsis tu ncua, txuag tau ntau lub sijhawm, tab sis kuj txuag tus nqi ntawm kev tu thiab tu.Nrog zoo stability, corrosion kuj, zoo heev ncua lub neej kev pab cuam.Muaj ntau hom, uas tuaj yeem xaiv raws li kev siv sib txawv.Cov cuab yeej ua rau cov hlau annealed yog qhov yooj yim, thiab kev siv tus nqi ntawm cov cuab yeej zoo tuaj.
