Q355b steel phaj
Lus piav qhia luv luv:
Hlau phaj yog lub tiaj tiaj steel phaj cam khwb cia nrog molten steel thiab nias tom qab txias.
Nws yog tiaj thiab duab plaub, uas tuaj yeem ncaj qha dov lossis txiav los ntawm dav hlau sawb.
Cov hlau phaj yog muab faib raws li thickness.Nyias steel phaj yog tsawg dua 4 hli (qhov thinnest yog 0.2 hli), nruab nrab tuab hlau daim hlau yog 4 ~ 60 hli, thiab cov hlau tuab ntxiv yog 60 ~ 115 hli.
Hlau phaj muab faib ua kub dov thiab txias dov raws li dov.
Qhov dav ntawm daim ntawv yog 500 ~ 1500 mm;Qhov dav ntawm lub thickness yog 600 ~ 3000 hli.Cov phaj nyias nyias tau muab faib ua cov hlau zoo tib yam, cov hlau zoo, cov hlau alloy, lub caij nplooj ntoo hlav, cov hlau tsis muaj steel, cov cuab yeej hlau, cov hlau tsis muaj cua sov, cov kabmob hlau, cov hlau tsis muaj steel thiab cov hlau ntshiab hlau nyias;Raws li kev siv, muaj cov roj chim phaj, enamel phaj, mos txwv phaj, thiab lwm yam;Raws li cov txheej txheem saum npoo, muaj galvanized ntawv, tinned ntawv, txhuas plated ntawv, yas puas steel phaj, thiab lwm yam.
Tmob plab
Cov qib steel ntawm tuab steel phaj yog qhov yooj yim tib yam li cov hlau phaj nyias.Nyob rau hauv cov nqe lus ntawm cov khoom, nyob rau hauv tas li ntawd mus rau lub choj steel phaj, boiler steel phaj, tsheb manufacturing steel phaj, siab nkoj steel phaj thiab ntau txheej high-pressure nkoj steel phaj, ib co ntau yam ntawm steel daim hlau, xws li tsheb girder steel phaj (2.5 ~ 10mm tuab), checkered steel phaj (2.5 ~ 8mm tuab), stainless hlau phaj, tshav kub-resistant steel phaj thiab lwm yam yog hla nrog nyias daim hlau.
Tsis tas li ntawd, steel phaj kuj muaj cov khoom siv.Tsis yog txhua daim hlau hlau yog tib yam.Cov khoom siv sib txawv, thiab qhov chaw siv lub phaj steel kuj txawv.
Cov khoom ntawm alloy steel
Nrog rau txoj kev loj hlob ntawm kev tshawb fawb, thev naus laus zis thiab kev lag luam, cov kev xav tau siab dua tau muab tso rau pem hauv ntej rau cov khoom siv, xws li lub zog siab dua, tsis kam mus rau qhov kub thiab txias, kub siab, qis kub, corrosion, hnav thiab lwm yam tshwj xeeb ntawm lub cev thiab tshuaj lom neeg.Cov pa roj carbon steel tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua.
Deficiency ntawm carbon steel:
(1) Tsawg hardenability.Feem ntau, qhov siab tshaj plaws ntawm cov dej quenched carbon steel tsuas yog 10mm-20mm.
(2) Lub zog thiab lub zog tawm los yog qhov tsawg.Xws li cov pa roj carbon zoo tib yam thiab Q235 steelσ S yog 235mpa, thaum tsis tshua muaj hlau alloy structural steel 16Mnσ S yog ntau tshaj 360MPa.40 steelσ s /σ B tsuas yog 0.43, qis dua li cov hlau alloy.
(3) Tsis zoo tempering stability.Vim qhov tsis zoo tempering stability, thaum cov pa roj carbon steel yog quenched thiab tempered, nws yog ib qhov tsim nyog yuav tau txais ib tug qis tempering kub nyob rau hauv thiaj li yuav xyuas kom meej muaj zog dua, yog li lub toughness ntawm cov hlau yog tsawg;Txhawm rau kom ntseeg tau tias zoo dua toughness, lub zog tsis tshua muaj thaum kub kub tau txais, yog li cov cuab yeej cuab tam ntawm cov pa roj carbon steel tsis siab.
(4)Nws tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm kev ua haujlwm tshwj xeeb.Cov pa roj carbon steel feem ntau tsis zoo nyob rau hauv oxidation tsis kam, corrosion kuj, kub tsis kam, tsis kub tsis kam, hnav tsis kam thiab tshwj xeeb electromagnetic zog, uas tsis tuaj yeem ua tau raws li qhov xav tau ntawm kev ua haujlwm tshwj xeeb.
