Dab tsi yog cov cuab yeej cuab tam ntawm A120 Rail?
Mechanical Properties ntawm lubA120 rail profileyog txhais los ntawm nws lub peev xwm los tiv thaiv huab cua compressive kev nyuaj siab, tiv thaiv nto abrasion, thiab tswj cov qauv kev ncaj ncees nyob rau hauv siab - zaus dynamic loading. Raws li qhovEuropean Txheem DIN 536 P1: 1991, cov khoom no tsis kho tab sis raug txiav txim los ntawm qhov tshwj xeebA120 Crane Rail Khoom Qibxaiv rau qhov project (piv txwv li, S700, S900, lossis S1100). A120 tshwj xeeb yog tsim los rau hnyav- daim ntawv thov lub luag haujlwm uas lub log loads feem ntau tshaj 60 tons, yuav tsum tau tshwj xeeb metallurgical tshuav nyiaj li cas ntawm hardness thiab ductility.
Cov ntsiab lus tseem ceeb ntawm cov tshuab hluav taws xob uas txhais tau tias ua raws DIN536 A120 Rail System suav nrog:
- Tensile zog (Rm): Qhov no yog qhov siab tshaj plaws kev tsheb nqaj hlau tuaj yeem tiv taus ua ntej ua tsis tiav. Nyob ntawm qib, qhov no nyob ntawm (690Nmm^2) rau cov ntawv thov txheej txheem mus rau tshaj (1080N/mm^2) rau siab -qhov chaw nres nkoj ib puag ncig.
- Yield zog (Re): Qhov no qhia txog lub ntsiab lus ntawm A120 steel rails yuav pib deform mus tas li. Lub ntsiab lus siab tau txais txiaj ntsig yog qhov tseem ceeb rau kev tiv thaiv lub taub hau tsheb ciav hlau los ntawm "flattening" hauv qab qhov hnyav ntawm crane log.
- Elongation (A5): Qhov no ntsuas qhov ductility ntawm A120 rail khoom. Qhov tsawg kawg nkaus elongation ntawm 8% mus rau 10% yog qhov yuav tsum tau ua kom ntseeg tau tias txoj kev tsheb ciav hlau tuaj yeem nqus tau lub zog tsis muaj kev tawg.
- Brinell Hardness (HBW): Hardness yog qhov tseem ceeb rau kev hnav tsis kam. Standard A120 rails feem ntau muaj lub taub hau hardness ntawm 260 txog 320 HBW, muab qhov chaw ua haujlwm - tawv thaum siv ua haujlwm.
GNEE RAILxyuas kom meej tias txhua lub Rail A120 batch raug kuaj xyuas nruj kom kuaj xyuas cov khoom no. Los ntawm kev tswj hwm cov khoom muaj pes tsawg leeg ntawm A120 rail, peb muab cov khoom lag luam uas ua tau raws li qhov hnyav -tonnage xav tau ntawm niaj hnub A120 overhead crane rail systems.
Kev sib piv ntawm A120 Rail Material Grade
Qhov kev ua tau zoo ntawm A120 rail profile txawv txav raws li qib steel xaiv. Xaiv cov qhab nia raug yog qhov tseem ceeb rau kev sib tw Crane Track qhov kev pab cuam lub neej nrog rau cov chaw siv nyiaj.
