Hlau hlau thiab hlau hlau muaj ntau yam zoo sib xws, tab sis ua tib zoo paub qhov txawv, yuav pom tias lawv tsis tsuas yog sib txawv ntawm cov khoom, tab sis kuj nyob rau hauv cov khoom yam ntxwv ntawm qhov sib txawv loj.Yog li thaum xaiv, nco ntsoov ua kom pom tseeb qhov txawv ntawm ob.Steel hlau Hoobkas qhia steel hlau carbon structural steel ua saum toj no, feem ntau tsis galvanized, siv rau machinery, caij nplooj ntoos hlav.Dub, tawv heev;Hlau: ua los ntawm cov hlau me me (mild steel), galvanized, siv rau kev sib koom ua ke thiab khi.Dawb thiab mos.
Qhov sib txawv tseem ceeb ntawm ob yog cov ntsiab lus carbon.Cov ntsiab lus carbon ntawm hlau yog 2.11 feem pua lossis ntau dua, thaum cov ntsiab lus carbon ntawm hlau yog 2.11 feem pua lossis tsawg dua.Cov hlau carbon hlau nrog cov ntsiab lus carbon siab tshaj 2.11% yog hlau cam khwb cia (npua hlau), uas yog qhov yooj yim tsis tuaj yeem thiab tsis tuaj yeem kos rau hauv cov hlau.Qhov thib ob, cov ntsiab lus ntawm impurities txawv.Cov ntsiab lus ntawm teeb meem impurities xws li sulfur thiab phosphorus hauv hlau yog me dua.Hlau hlau xim xim tsom, hlau hlau xim lub teeb taw tes, dawb taw tes.
Lub neej ntawm "xaim", yog qhov tseeb "tsawg carbon steel hlau", cov ntsiab lus carbon tsawg dua 0.2%.Qhov saum npoo feem ntau yog coated nrog zinc plating 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 ntawm "steel hlau", yog cov ntsiab lus carbon nyob rau hauv li 0.6% ntawm "carbon steel hlau", los yog cov ntsiab lus carbon nyob rau hauv li 0.8% ntawm "high carbon steel hlau", lawv muaj txaus hardness thiab elasticity tom qab tsim nyog kho cua sov. , siab zog.Siv xws li winding dog dig caij nplooj ntoos hlav thiab hais txog.
Annealed hlau yog cov hlau mos hlau ua los ntawm cov hlau tsis tshua muaj hlau txias txias, cua sov, qhov kub thiab txias, txuag hluav taws xob thiab lwm yam txheej txheem.Cov muaj pes tsawg leeg ntawm cov hlau hlau txawv raws li nws siv.Nws muaj hlau, cobalt, npib tsib xee, tooj liab, carbon, zinc, thiab lwm yam khoom.Cov hlau kub kub dov rau hauv 6.5 hli tuab steel bar yog cov hlau pas nrig, thiab tom qab ntawd muab tso rau hauv cov khoom siv hlau kos rau hauv ib txoj kab sib txawv ntawm txoj kab, thiab maj mam txo cov aperture ntawm cov hlau phaj, txias, annealing, plating thiab lwm yam. ua tshuab ua los ntawm ntau yam specifications ntawm hlau hlau.
Annealed hlau yog tsim los ntawm cov hlau mos hlau los ntawm cov pa roj carbon tsawg cua sov, kub kos duab, qhov kub thiab txias thiab lwm yam txheej txheem.Vim tias qhov sib txawv ntawm kev siv, kuj tseem muaj qhov sib txawv ntawm cov txheej txheem tsim khoom, thiab cov kev qhia tshwj xeeb muaj ntau yam.Annealed hlau tuaj yeem siv dav, feem ntau vim tias cov hlau annealed thiab lwm yam 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 kev ruaj ntseg zoo, zoo corrosion kuj, zoo heev rau lub neej kev pab cuam.Ntau hom, tuaj yeem xaiv raws li kev siv sib txawv, ua rau cov khoom siv hlau annealing yog yooj yim, txhim khu kev siv tus nqi ntawm cov cuab yeej.
