Lub Tensile Strength ntawm A120 Steel Rail yog dab tsi?
Lub zog tensile ntawmA120 steel railfeem ntau yog nyob ntawm qhov tsawg kawg nkaus ntawm690 N / mm² txog li 1080 N / mm², nyob ntawm seb cov khoom siv qib twg xaiv. Nyob rau hauv DIN 536 Standard Crane Rail moj khaum, cov txiaj ntsig no tau muab faib ua cov qib kev ua tau zoo xws li Qib 700 (Ntau dua lossis sib npaug rau 690 N / mm²), Qib 900 (Ntau dua lossis sib npaug rau 880 N / mm²), thiab siab -Kev Ua Haujlwm Qib N / mm² lossis sib npaug li 1100). Qhov no ua kom ntseeg tau tias A120 rail profile tuaj yeem sib phim rau cov neeg kho tshuab tshwj xeeb ntawm ntau qhov chaw nqa khoom.
- Qib 700 (S700):Muab lub zog tensile ntawm Ntau dua lossis sib npaug rau 690 N / mm², zoo tagnrho rau - lub hom phiaj A120 overhead crane rail systems.
- Qib 900 (S900):Muab lub zog tensile ntawm Ntau dua lossis sib npaug rau 880 N / mm², sawv cev rau kev lag luam tus qauv rau siab - zaus A120 steel rails.
- Qib 1100 (S1100):Muab lub zog tensile ntawm Ntau dua lossis sib npaug rau 1080 N / mm², tshwj xeeb yog tsim los rau cov khoom hnyav uas pom hauv kev ua haujlwm hnyav gantry crane.
- Yield Strength Correlation:Lub zog tensile siab dua feem ntau yog nrog los ntawm cov ntsiab lus siab dua, tso cai rau A120 hnyav rails rov qab mus rau lawv cov qauv qub tom qab lub crane hla.

GNEE RAILtsim A120 steel crane rail siv cov txheej txheem metallurgical siab heev uas ua kom cov qauv zoo ib yam thiab cov khoom tensile zoo ib yam thoob plaws qhov ntev ntawm txoj kev tsheb ciav hlau. Los ntawm kev tswj hwm tus nqi txias thiab cov khoom sib txuas ntxiv thaum lub sijhawm tsim khoom, peb lav tias peb cov khoom siv tsheb ciav hlau A120 ua tau raws li lossis tshaj li cov neeg siv khoom xav tau ntawm European Standard DIN 536 P1: 1991.
Vim li cas Tensile Strength yog qhov ntsuas qhov ua tau zoo rau A120 Rail?
Nyob rau hauv lub ntiaj teb no ntawm hnyav- lub luag hauj lwm infrastructure, lub tensile lub zog (feem ntau ntsuas nyob rau hauv Newtons ib square millimeter) yog qhov tseeb metric rau kev ntsuam xyuas cov khoom muaj pes tsawg leeg ntawm A120 rail thiab nws tsis kam mus rau cov yam ntxwv tsis ua hauj lwm. Thaum lub crane log hnyav50 tontxav raws A120 rail profile, nws tsim immense localized siab. Lub zog tensile txiav txim siab txoj kev tsheb ciav hlau lub peev xwm los tiv thaiv cov crushing rog thiab tom qab "rub" rog (nruj) uas tshwm sim hauv lub vev xaib tsheb ciav hlau thiab lub hauv paus.
Lub zog tensile ntau dua nyob rau hauv A120 steel rails ncaj qha txhais rau kev qaug zog zoo dua. Qhov no yog qhov tseem ceeb tshwj xeeb rau A120 crane lem raug rau ntau lab lub voj voog. Yog tias lub zog tensile tsawg dhau rau daim ntawv thov, txoj kev tsheb ciav hlau tuaj yeem tsim micro- tawg lossis "nceb" ntawm lub taub hau, ua rau muaj kev puas tsuaj loj ntawm DIN536 A120 Rail System.
- Fracture Resistance:Lub zog tensile siab tiv thaiv txoj kev tsheb ciav hlau los ntawm snapping nyob rau hauv kev cuam tshuam tam sim ntawd.
- Surface Durability:Cov qib muaj zog ntawm A120 cov khoom siv rail tiv thaiv cov khoom siv los ntawm kev siv lub log tsheb ntau zaus.
- Structure Integrity:Xyuas kom lub A120 nyiaj siv ua haujlwm crane rail systems tswj lawv cov kev sib dhos txawm tias nyob rau hauv qhov siab tshaj plaws.
FAQ
- Puas yog lub zog tensile siab dua ib txwm zoo dua rau A120 rails?
Tsis tas li. Thaum lub zog tensile siab dua (xws li Qib 1100) muaj kev hnav zoo dua, nws kuj tseem nyuaj rau vuam thiab tsis tshua muaj ductile. Rau ntau tus qauv A120 nyiaj siv ua haujlwm crane rail systems, Qib 900 muab qhov zoo tshaj plaws sib npaug ntawm lub zog, tus nqi, thiab kev yooj yim ntawm kev teeb tsa.
- Lub zog tensile cuam tshuam li cas rau vuam ntawm A120 rails?
High- tensile A120 rail khoom yuav tsum tau tshwj xeeb Alumothermic Vuam cov khoom siv rau Rails thiab nruj ua ntej- cov txheej txheem cua sov. Yog tias cov txheej txheem vuam tsis zoo sib xws rau qib tensile, qhov sib koom ua ke tuaj yeem ua rau nkig, ua rau tawg ntawm A120 crane lem.
- Kuv puas tuaj yeem txiav txim siab lub zog tensile ntawm A120 rail los ntawm nws qhov ntev?
Tsis yog. Lub DIN A120 Rail Dimensions yog tib yam nyob rau txhua qib. Lub zog tensile yog txiav txim siab los ntawm cov khoom muaj pes tsawg leeg ntawm A120 rail thiab cov txheej txheem kev kho cua sov, uas tsuas tuaj yeem txheeb xyuas tau los ntawm Daim Ntawv Pov Thawj Mill Test (MTC).
- Kev sib raug zoo ntawm hardness (HBW) thiab tensile zog (Rm) yog dab tsi?
Feem ntau, thaum lub zog tensile nce, Brinell hardness kuj nce. Rau A120 rail profile, Qib 700 feem ntau muaj qhov nyuaj ntawm Ntau dua lossis sib npaug rau 200 HBW, thaum Qib 1100 tuaj yeem ncav cuag Ntau dua lossis sib npaug rau 300 HBW.
- Puas yog qhov hnyav ib 'meter' hloov nrog lub zog tensile sib txawv?
Tsis yog. Lub A120 rail nyhav ib meter tseem nyob li ntawm 101.2 kg / m tsis hais lub tensile lub zog, raws li qhov ceev ntawm cov hlau tseem nyob tas li. Lub zog tensile tsuas yog hloov cov khoom siv sab hauv ntawm A120 hnyav rails.
