Dab tsi yog tus qauv S20 rail mechanical zog?
Mechanical Properties ntawm aDIN 5901 S20 rail txhais tau tias nws muaj peev xwm tiv taus ntsug loads, tiv thaiv nto hnav, thiab tswj kev ncaj ncees nyob rau hauv lub dynamic stresses ntawm industrial ua hauj lwm. Thaum lub S20 rail qhov ntev (100 hli qhov siab, 82 hli puag) yog kho los ntawm German tus qauv, qhov tseeb mechanical kev ua tau zoo yog dictated los ntawm xaiv steel qib- feem ntau 55Q los yog Q235B.
- Tensile zog (σb):Qhov no sawv cev rau qhov siab tshaj plaws txoj kev tsheb nqaj hlau tuaj yeem tiv taus thaum raug ncab. Rau siab -carbon 55Q rail hlau, qhov no feem ntau yog ntau dua lossis sib npaug rau 710 MPa, muab cov txheej txheem pob txha rau 3.5-tuj qag loads.
- Surface Hardness (HB):Hardness yog qhov tseem ceeb rau 30 mm S20 rail taub hau dav. Standard rail steel (55Q) muaj Brinell hardness ntawm 200-240 HB, uas tiv thaiv lub taub hau los ntawm "mushrooming" nyob rau hauv lub concentrated siab ntawm steel log.
- Yield zog (σs):Qhov no yog lub ntsiab lus uas S20 rail profile yuav mus tas li deform. Rau 55Q steel, lub zog tawm los feem ntau yog ntau dua lossis sib npaug rau 410 MPa, ua kom cov tsheb ciav hlau rov qab mus rau nws cov qauv qub tom qab lub crane hnyav dhau.
- Elongation (d 5):Qhov no ntsuas cov khoom ductility. Tus qauv S20 kev tsheb nqaj hlau hauv qib 55Q muaj qhov elongation ntawm Ntau dua lossis sib npaug li 13%, muab qhov yooj yim txaus los nqus cov vibrations yam tsis muaj kev tawg.

GNEE RAILxyuas kom txhua batch ntawmDIN 5901 S20 railua tau raws li cov qauv kev ntsuas no los ntawm kev kuaj xyuas nruj. Los ntawm kev tswj hwm cov tshuaj muaj pes tsawg leeg-tshwj xeeb tshaj yog cov manganese thiab carbon ratios- peb xaS20 Hlau Railuas sib npaug hnyav hnyav nrog cov qauv toughness yuav tsum tau rau gantry cranes, mining thauj, thiab automated warehouse lem.
Yuav Ua Li Cas Cov Khoom cuam tshuam S20 Rail Load Capacity?
Lub S20 rail load peev yog ib tug ncaj qha tshwm sim ntawm cov neeg kho tshuab zog ua hauj lwm nyob rau hauv unison nrog lub 100 hli profile qhov siab. Lub zog yield zog ntawm 55Q steel tso cai rau txoj kev tsheb ciav hlau los ua ib lub nqaj tawv ntawm cov neeg pw tsaug zog. Qhov no tiv thaiv lub 7 hli web ntawm buckling nyob rau hauv ntsug siab.
Hauv kev teeb tsa kev lag luam, S20 lub teeb steel rail nrog cov khoom siv tshuab tuaj yeem txhawb nqa qag ntawm 2.5 txog 3.5 tons. Txawm li cas los xij, yog tias cov khoom siv hardness tsawg dhau (raws li qee qhov tsis yog- qauv steels), lub taub hau tsheb ciav hlau yuav flatten nyob rau lub sijhawm, ua rau cov dov tsis kam thiab kev siv zog rau kev mus ncig. Ua raws li S20 rail specifications rau hardness kom ib tug du, npaum khiav nto rau xyoo lawm.
Lub luag haujlwm ntawm Manganese hauv Rail Durability
Manganese yog ib qho tseem ceeb alloying nyob rau hauv S20 rail technical data. Nws tsub kom lub "hardenability" ntawm cov hlau thiab refines nws grain qauv. Hauv qib zoo li 50Mn lossis 55Q, manganese pab txoj kev tsheb ciav hlau tiv thaiv lub zog abrasive ntawm grit thiab ore plua plav hauv qhov chaw mining.
Qhov zoo ntawm metallurgical no ua kom ntseeg tau tias S20 rail hla ntu tswj nws qhov kev ncaj ncees geometric. Yog tias tsis muaj manganese txaus, RAIL S20 MATERIAL SRENGTH yuav raug cuam tshuam, ua rau muaj kev qaug zog ntxov ntxov nyob ze ntawm lub qhov taub ntawm S20 rail fishplate. GNEE RAIL txoj kev mob siab rau siab -purity alloys xyuas kom meej tias peb cov rails muab lub neej ua haujlwm tau zoo thiab nyab xeeb.
FAQ
- Dab tsi yog cov cuab yeej tseem ceeb tshaj plaws rau crane lem?
Surface hardness yog qhov tseem ceeb. Lub 200–240 HB pom nyob rau hauv 55Q qib steel ua kom lub taub hau 30 hli tsis deform nyob rau hauv lub siab -frequency point loads ntawm gantry crane log.
- Puas yog S20 rail hnyav ib 'meter' hloov nrog qib sib txawv?
Tsis yog S20 steel rail hnyav tseem 19.80 kg / m. Cov khoom siv kho tshuab yog los ntawm cov tshuaj muaj pes tsawg leeg, uas tsis cuam tshuam qhov ntom ntawm cov hlau.
- Yog vim li cas elongation tseem ceeb rau kev tsuas rails?
Mining lem feem ntau muaj kev hloov hauv av. Ib qho elongation ntawm ntau dua los yog sib npaug li 13% ua kom lub S20 lub teeb tsheb ciav hlau tuaj yeem hloov tau me ntsis yam tsis muaj snapping, tswj kev nyab xeeb hauv av ib puag ncig.
- Puas yog S20 rail nkig?
Standard S20 rails tsis nkig; lawv yog "nyuaj." Tus qauv DIN 5901 ua kom lawv muaj qhov toughness txaus (elongation) los daws cov kev cuam tshuam kev lag luam thaum tseem tshuav txaus los txhawb nqa hnyav.
