FAQ
Q: Vim li cas 16MnCr5 feem ntau nyiam tshaj 5115 rau cov iav nrog ib ntu tuab saum 25mm?
A: Vim hais tias 16MnCr5 muaj ntau dua manganese thiab chromium, nws hardens tob dua . 5115 muaj cov pa roj carbon tsawg me ntsis thiab tsis muaj zog hardenability, yog li cov tub ntxhais yuav nyob twj ywm mos nyob rau hauv thicker seem. Rau ib lub iav uas xav tau cov tub ntxhais tawv tawv los txhawb rooj plaub, 16MnCr5 muab cov tub ntxhais zoo sib xws tom qab quenching. Yog tias koj tab tom ua tus pins me me lossis nyias nyias, 5115 yog qhov zoo. Rau cov tsheb thauj khoom lossis hnyav- lub luag haujlwm shafts, 16MnCr5 yog qhov kev xaiv zoo dua.
Q: Dab tsi yog qhov txawv ntawm carburizing ntawm 880-980℃thiab core -hardening ntawm 860-900℃- yog cov kauj ruam cais?
A: Carburizing yog qhov siab -kub theem uas carbon diffuses rau saum npoo. Tom qab ntawd, koj txias rau 860–900℃rau cov tub ntxhais- hardening, ces quench. Qhov kub qis dua refines cov nplej thiab txo cov distortion. Yog tias koj lub qhov cub tso cai rau quenching ncaj qha los ntawm qhov kub thiab txias, koj tuaj yeem hla qhov nruab nrab txias, tab sis koj yuav muaj kev pheej hmoo ntawm coarser nplej thiab ntau distortion. Rau precision iav, txias rau 860-900 degree, sib npaug, ces quench. Case{11}} hardening ntawm 780-820℃yog ib qho reheat cais siv tom qab txias nruab nrab los yog rau xaiv hardening.
Q: Kuv puas tuaj yeem siv 16MnCr5 nyob rau hauv cov xwm txheej tsis zoo ntawm cov mos mos annealed?
A: Yog, tab sis nws nyuaj rau cov cuab yeej. Normalized muab 138-187 HBW, thaum mos annealed tsawg dua los yog sib npaug rau 207 HBW. Cov qauv zoo li qub yog qhov sib txawv dua thiab tuaj yeem ua kom zoo dua qhov chaw tiav hauv qee qhov haujlwm, tab sis rau hobbing, drilling, lossis broaching, mos annealed yog yooj yim dua thiab txuas lub neej ntawm cov cuab yeej. Yog tias koj tab tom tig los yog milling cov duab yooj yim, normalized yuav ua tau. Rau iav txiav, lo nrog mos annealed.
Q: Yuav ua li cas kuv kwv yees qhov tseem ceeb hardness tom qab carburizing thiab quenching rau ib tug muab bar txoj kab uas hla?
A: Core hardness nyob ntawm seem loj thiab quench ceev. Rau 16MnCr5, me me hauv qab 16 hli tuaj yeem ncav cuag 30-35 HRC core hardness tom qab tempering ntawm 200 degree. Qhov ntawd sib haum rau qhov tsawg kawg nkaus 1000 MPa tensile lub zog teev rau qhov loj. Raws li txoj kab uas hla nce, core hardness poob. Rau 40-100mm seem, qhov tsawg kawg nkaus tensile zog yog 600 MPa, uas yog kwv yees li 20-25 HRC. Yog tias koj xav tau cov tub ntxhais muaj zog ntau dua hauv ntu loj, koj tuaj yeem xav tau qib sib txawv lossis nrawm dua.
Q: Puas yog Suav qib 16CrMnH hloov ncaj qha rau EN 16MnCr5?
A: Tsis yog ib txwm. 16CrMnH ib GB/T 5216 muaj cov hardenability bands (a thiab b) uas txawv ntawm EN 10084. Cov manganese thiab chromium ranges sib txawv, uas cuam tshuam qhov sib sib zog nqus ntawm cov hlau. Rau qhov tsis yog- qhov tseem ceeb, kev hloov pauv tuaj yeem ua haujlwm. Rau cov iav uas yuav tsum tau raws li qhov tshwj xeeb Jominy nkhaus lossis rooj plaub qhov tob, koj yuav tsum sib piv cov ntaub ntawv hardenability ntawm lub zeb. Peb tuaj yeem muab ob qib nrog cov ntaub ntawv qhia txog tshuaj lom neeg thiab tawv tawv, tab sis koj pab neeg ua haujlwm yuav tsum pom zoo rau kev hloov pauv.
Q: Koj puas npaj 16MnCr5 hauv cov kab me me rau kev sim, thiab koj puas tuaj yeem txiav luv luv?
A: Peb tuav ntau tshaj 5000 tons hauv peb lub tsev rau khoom, suav nrog carbon steel series. Rau 16MnCr5, peb Tshuag puag ncig tuav los ntawm Φ18-460mm hauv 6m ntev. Peb tuaj yeem txiav raws li koj xav tau ntev, suav nrog luv luv rau kev sim. Tsis muaj qhov tsawg kawg nkaus rau kev txiav tawm ntawm cov khoom lag luam, txawm tias qhov tsawg heev yuav muaj tus nqi tuav. Txhua qhov kev xa khoom tuaj nrog kev nro, hardness, thiab spectrophotometer test reports. Qhia peb txoj kab uas hla, qhov ntev, thiab qhov ntau, thiab peb yuav hais qhov kev xaiv ceev tshaj plaws.
