Dab tsi yog qhov nyuaj ntawm S20 steel rails?

Dab tsi yog qhov nyuaj ntawm S20 steel rails?

Hardness ntawm aDIN5901 S20 steel railyog nyob ntawm qhov tshwj xeeb metallurgy thiab qib steel xaiv thaum tsim khoom. Vim tias tus qauv DIN 5901 feem ntau tswj hwm cov duab geometric thiab qhov ntev (19.8 kg / m, 100 mm qhov siab), GNEE RAIL muab cov qib steel sib txawv kom haum raws li qhov yuav tsum tau muaj hardness ntawm ntau yam kev lag luam ib puag ncig.

Lub hardness profiles rau ob qib steel feem ntau siv los yob S20 rails yog cov ntsiab lus hauv qab no:

Siab-Carbon / Hnav-Resistant Qib (55Q)

• Brinell Hardness: Ntau dua lossis sib npaug rau 197 HBW (feem ntau yog nyob nruab nrab ntawm 200 txog 240 HBW)

• Tensile Strength: Ntau dua lossis sib npaug ntawm 685 MPa

• Cov yam ntxwv: Qib no muaj cov pa roj carbon ntau dua thiab manganese (0.50% txog 0.60% C), uas ua rau cov tawv tawv thiab hnav tsis kam. Nws yog tus qauv kev lag luam rau siab -cycle automated storage and retrieval systems (ASRS), gantry crane runways, and abrasive material handle lem where contact fatigue and wheel-on-rail coj yuav tsum tau txo kom tsawg.

Tsawg-Carbon / Qib Qib (Q235B)

• Brinell Hardness: 120-160 HBW

• Tensile zog: 375-460 MPa

• Yam ntxwv: Qhov no yog softer, ntau ductile carbon steel. Thaum nws muaj qis dua qhov tawv tawv, nws muaj kev cuam tshuam zoo heev, tawg toughness, thiab superior thaj weldability. Nws raug xaiv rau qis dua - cov kab ntau zaus hloov chaw, cov hlua sib txuas sab hauv tsev, lossis cov lem uas yuav tsum tau txias heev - dabtsi yog khoov lossis sib koom ua ke vuam.

S20 Rail Material Properties tiv thaiv Deformation li cas?

Kev ua haujlwm ntawm Lub Teeb Rail S20 kev teeb tsa tiv thaiv kev sib tsoo hauv cheeb tsam thiab qhov chaw ntog nyob rau hauv ib txwm muaj kev khiav tsheb txhua hnub nyob ntawm qhov sib piv ntawm cov tshuaj tswj thaum lub sij hawm ladle metallurgy. Thaum dov cov log tsheb muaj kev kub ntxhov ntawm qhov nqaim 44.00 hli lub taub hau yas, cov khoom siv hauv qab yuav tsum tiv thaiv cov yas deformation kom tsis txhob muaj kev puas tsuaj ntxov ntxov.

Lub DIN 5901 S20 Rail Material Strength yog ua tiav los ntawm kev ua kom muaj cov pa roj carbon siab -manganese piv hauv cov tshuaj muaj pes tsawg leeg, siv tag nrho cov hlau sib txawv uas muab cov txheej txheem tshwj xeeb ntom ntom ntom ntom. Manganese ntxiv yog tswj kom nruj ntawm 0.70% thiab 1.20% kom nce kev ua haujlwm zoo - lub peev xwm hardening ntawm cov hlau khiav, txhais tau hais tias lub taub hau khiav ua nruj dua nyob rau hauv kev sib tw txuas ntxiv. Qhov no S Hom Rail metallurgical mis kuj tseem khaws cia zoo heev hauv kev sib txuas, cia rau ntawm - cov neeg ua haujlwm hauv tsev ua cov txheej txheem thermit lossis flash-tooj vuam ua haujlwm yam tsis ua rau cov cua sov nkig- thaj chaw cuam tshuam.

Peb lub chaw soj ntsuam lub cev muaj zog ua haujlwm tsis tu ncua, suav nrog kev kuaj xyuas tensile txwv thiab microstructural micro-hardness mapping, ua kom tag nrho cov kev sib raug zoo nrog European rail profiles. Cov qauv zoo sab hauv no tau lees paub tias peb cov S20 steel rails tiv taus qhov sib sib zog nqus gouging thiab nto tawg txawm tias thaum siv nyob rau hauv siab -corrosion mine shafts los yog hnyav ua tshuaj.

FAQ

• Yuav ua li cas lub hardness range ntawm 200-260 HBW tiv thaiv S20 lub teeb rail systems los ntawm lub taub hau flattening?

Qhov nyuaj ntawm qhov chaw ntawm 200-260 HBW muab lub zog tawm los tiag tiag uas xav tau los tiv thaiv cov yas deformation mus tas li nyob rau hauv lub log dynamic hu mus rau qhov profile 5.0-tuj qag txwv. Cov txheej txheem hardness no txwv cov hlau los ntawm kev sib kis lossis flattening sab nraud nyob rau hauv kev thauj khoom tas mus li, tswj kom huv si 44.00 mm khiav saum npoo ntawm kev ua haujlwm ntev.

• Cov kev cai kho cua sov puas tuaj yeem siv los ua kom muaj zog ntawm S20 Steel Track Rail?

Yog lawm, rau cov ntawv tshwj xeeb hauv kev lag luam uas ntsib kev sib tsoo hnyav lossis lub log hnyav, S20 Steel Track Rail tuaj yeem raug xaiv los ntawm - kab induction hardening kev kho mob kom ua kom lub taub hau saum npoo hardness siab dua 300 HBW. Qhov kev cai ua no tswj hwm lub hauv paus kev tsheb ciav hlau zoo heev thaum ua kom muaj kev tiv thaiv ntawm cov yas khiav tawm tsam dov kev sib cuag qaug zog.

• Yuav ua li cas lub sab hauv web hardness ntawm DIN 5901 S20 Rail tiv thaiv kev tawg ib ncig ntawm lub qhov taub?

Lub hauv paus metallurgy ntawm DIN 5901 S20 Rail lub vev xaib tau khaws cia nrog kev pom zoo tawg toughness thiab nruab nrab hardness kom nqus tau siab shear rog nyob ze ntawm kev sib txuas tsis muaj tawg. Cov txheej txheem ductility no txwv tsis pub muaj kev ntxhov siab nyob ib puag ncig ua ntej -drilled sib koom ua ke bar bolt qhov, txwv tsis pub kab rov tav lub vev xaib sib cais thaum lub sij hawm khaus locomotive braking sequences.

• Dab tsi yog qhov kev sib raug zoo ntawm S20 profile hardness thiab nws qhov siab tshaj plaws kev khiav hauj lwm tshaj tawm?

Lub hnab ntawv 200–260 HBW hardness yog optimized rau qis - mus rau - nruab nrab ceev kev thauj khoom thauj, mining corridors, thiab gantry paths ua hauj lwm nyob rau hauv 50 km / h. Ntawm cov qauv nrawm no, txoj kev tsheb ciav hlau ua tiav ua tiav txo qis lub ntsej muag hnav thiab lub log flange kev sib txhuam, txo qhov ntev -cov nqi tu thiab kho qhov sib txawv.
