10Crmoal yog cov hlau tshwj xeeb tiv thaiv {}} cov khoom siv roj av yog cov khoom siv dej hiav txwv, cov ntug dej hiav txwv, cov nroj tsuag dej hiav txwv. Nws kuj tseem siv tau los ua kev siv valve.
Tus "al" nyob rau hauv qeb 10Crocoal reacts nrog oxygen nyob rau hauv cov pa tawm ntawm cov duab tiv thaiv kab mob steel} Txuas ntxiv, "CR" thiab "mo" Qhov no tseem ceeb txuas lub neej pabcuam ntawm cov hlau.
10Crmoal yog tsim kev siv hluav taws xob rauv statold steelmaking, feem ntau los ntawm cov ntawv txheej txheem hlau, ua rau muaj kev coj dawb huv. Lub phaj steel yog tsim los ntawm poling molten hlau, uas yog ces txias thiab nias rau hauv daim ntawv tiaj tus. Cov phiaj no yog tiaj tus thiab duab dhos, thiab tuaj yeem siv lub ntsej muag ncaj qha lossis sheared los ntawm ntau lub steel ib daim. Raws li cov tuab, cov phiaj hlau tau muab cais raws li hauv qab no: cov phiaj hlau nyias nyias (<8 mm, with the thinnest being 0.2 mm), medium-thick plates (8–60 mm), and extra-thick plates (60–120 mm).
Kev tsim qauv ntawm 10Crmroal steel phaj qib 5:
"10": Qhia cov ntsiab lus carbon ntawm cov hlau phaj.
"Crrohal": Qhia tias cov hlau phaj muaj cov tshuaj sib xws xws li chromium, molybdenum, thiab txhuas.
10Crmoal steel phaj Ex tiav cov qauv: ua raws li GB / T 30070-2013.
Qhov ntev, cov duab, qhov hnyav, thiab cov kev sib txawv ntawm 10croal steel phaj:
a. Qhov ntev, cov duab, thiab kev cia siab sib txawv ntawm cov phaj steel yuav tsum ua raws li cov kev cai ntawm lub teb chaws tus qauv.
b. Lub thickness sib txawv ntawm cov hlau phaj yuav ua raws li chav kawm b sib txawv ntawm GB / T 709. Raws li cov neeg siv khoom CB / T 709 kuj muaj.
c. Cov phaj Steel tau xa raws li qhov hnyav hnyav, suav siv cov hlau ntom ntawm 7.85 g / cm³.
Kev xa khoom ntawm 10Croal Steel phaj:
Rau thickness tsawg dua los yog sib npaug rau 30 hli: tempered lossis ib txwm + tempered.
Rau thickness> 30 hli: normized + tempered.
Qhov kev xa tuaj kuj tseem tuaj yeem raug qhia raws li kev xav tau kev xav tau.
Los ntawm -} thickness kev ua haujlwm yuav tsum tau rau 10cmoal steel phaj: Z15, Z35.
Cov kev ntsuam xyuas ultrasonic rau 10Crmoal Steel Phaj: Chav Kawm 1, Chav Kawm 2, Chav 3.
Cov Khoom Siv Neeg Kho Tshuab ntawm 10Crmoal Hlau:
Qib: 10croal
Tensile lub zog (σB / MPA): ntau dua lossis sib npaug nrog 510-680 MPA
YEED POINT (σS / MPA): Ntau dua lossis sib npaug nrog 300-310 MPa
Elongation: ntau dua los yog sib npaug rau 19%
Kev cuam tshuam lub zog ntawm 20℃(aku2 / j): ntau dua los yog sib npaug rau 34 j
180 Qib Dabtsi Yog Khwv Kev Xeem: D =2 a
Nco tseg: Cov khoom siv cov neeg kho mob tshwj xeeb yuav tsum tau qhia hauv cov ntawv xeem zeb xeem.
Thaum lub phaj steel xa tawm hauv kub - qhov tseem ceeb ntawm tensile muaj zog (σs, σ 5, akv) yog muab rau kev siv.
Cov charpy (v - tsis muaj zog) cuam tshuam lub zog hluav taws xob tau muab xam raws li kev sib cais nruab nrab ntawm ib pawg peb cov hnoos qeev. Ib tus nqi ib tus neeg yuav qis dua tus nqi teev tab sis yuav tsis qis dua 70% ntawm tus nqi teev tseg.
Rau kev sib tw xeem ntawm cov phaj hlau nrog cov tuab ntawm tsawg dua 12 hli × 10 hli × 10 hli × 10 mm yuav tsum siv. Thaum siv 5 hli × 10 hli × 55 mm hom 55 mm × 55 mm spec 55 mm × 55 qhov kev xeem tau yuav tsis tsawg dua 50% ntawm tus nqi teev tseg. Thaum siv 7.5 hli × 10 hli × 55 mm hom 55 mm × 55 hli hnoos qeev, qhov kev xeem tau yuav tsis tsawg dua 75% ntawm tus nqi teev tseg.
Ntau lawm thiab tej txheej txheem ntws ntawm 10croal steel phaj:
Cov Txheej Txheem Ntau Lawm:
Koom haum siv cov tshuaj ntsuam → kev kuaj xyuas kub ntxiv
Tej txheej txheem txiav:
After the performance indicators of the 10CrMoAL steel plate meet the requirements in the factory inspection, cutting processing is carried out according to the cutting technology. It can be cut and processed according to drawings. Generally, when the steel plate thickness is ≤20 mm, CNC plasma cutting or CNC laser cutting is preferred. If the steel plate thickness is >30 hli, CNC nplaim taws txiav yog feem ntau raug xaiv los tswj kev txiav kev txiav txim siab thiab lub sijhawm.
