Vim li cas cov khoom siv zog tseem ceeb rau A100 Profiles?

Cov khoom siv zog ntawm aDIN 536 A100 railyog lub hauv paus tseem ceeb txiav txim seb qhov hnyav npaum li cas nws tuaj yeem nqa tau thiab nws yuav kav ntev npaum li cas ua ntej cov hlau pib lub cev deform. Vim hais tias cov log cranes ua haujlwm loj "point loads" es tsis yog qhov hnyav, qhov kev ncaj ncees ntawm cov qib steel yog qhov tseem ceeb.

Ntawm no yog vim li cas cov khoom siv dag zog yog qhov tseem ceeb tshaj plaws sib txawv hauv A100 rail kev ua tau zoo:

1. Resistance rau "Mushrooming" (Plastic Deformation)

Yog hais tias cov khoom siv Yield Strength tsawg dhau rau lub crane lub log load, lub taub hau rail yuav undergo yas deformation.

• Txheej txheem:Lub taub hau dav ntawm 100 mm pib flatten thiab nthuav tawm sab nraud, zoo li lub nceb.

• Lub txim:Qhov no hloov cov geometry ntawm txoj kev tsheb ciav hlau, ua rau lub log crane taug qab tsis raug, ua rau muaj kev vibration thiab muaj peev xwm ua rau lub crane bearings thiab motors.

2. Txhawb nqa Vertical Compression hauv Web

A100 yog nto moo rau nws60 mm tuab, tab sis thickness ib leeg tsis txaus. Cov khoom siv yuav tsum muaj lub zog compressive los tuav lub zog ntsug yam tsis muaj kev ua haujlwm sab hauv.

• Point Loading:Tsis zoo li cov qauv tsheb ciav hlau, crane log feem ntau yog ua los ntawm cov hlau tsis tshua muaj zog forged. Qhov chaw sib cuag yog me me, tsim kom muaj kev ntxhov siab loj.

• Integrity:High-lub zog hlau ua kom ntseeg tau tias "sab hauv kev ntxhov siab" hauv lub vev xaib tseem nyob hauv qab cov khoom tsis ua haujlwm, tiv thaiv cov kab nrib pleb sab hauv uas tuaj yeem ua rau muaj kev puas tsuaj loj.

3. Nto Hardness thiab Abrasive Hnav

Lub zog thiab hardness yog zoo sib xws. Hauv siab -frequency gantry systems (xws li cov nyob hauv cov chaw nres nkoj tsis khoom thauj khoom), kev sib txhuam ntawm lub log flange thiab lub taub hau tsheb ciav hlau tsis tu ncua.

• Hnav Rate:Txheem lub zog steel (kwv yees . 260 HB) hnav sai dua li siab - lub zog lossis cua sov- kho steel (340–380 HB).

• Maintenance Savings:Xaiv lub zog ntawm cov khoom siv ntau dua yuav txo qhov zaus ntawm kev sib tsoo tsheb ciav hlau thiab txuas ntxiv lub sijhawm ntawm kev hloov pauv tag nrho, txo qis "Tag nrho Tus Nqi Ntawm Cov Tswv Cuab."

Dab tsi yog cov khoom siv thiab qhov loj me ntawm DIN 536 A100 rail?

DIN 536 A100 yog kub- dov, tiaj tus- hauv qab crane tsheb ciav hlau txhais los ntawm German cov qauv (DIN 536), nrog lub taub hau dav 100mm, 95mm qhov siab, thiab 74.3 kg / m hnyav, tsim rau hnyav crane loads. Cov qib steel ntau, suav nrog 700, 900A, thiab 1100, muaj zog tensile xws li 690 txog 1080 N / mm². Cov ntsiab lus tseem ceeb suav nrog 200mm puag, 60mm web thickness, thiab 10-12m tus qauv ntev.

FAQ

• Cov khoom siv zog puas cuam tshuam rau 74.3 kg / m qhov hnyav?

tsis muaj. qhov hnyav yog qhov ua haujlwm ntawm a100 crane rail qhov ntev. Txawm hais tias koj siv lub zog qis - lub zog lossis siab - lub zog steel, qhov ceev tseem tseem zoo ib yam; tsuas yog cov kev ua haujlwm kho tshuab hloov pauv.

• Lub zog cuam tshuam li cas rau kev sib tsoo?

cov ntaub ntawv muaj zog (lub taub hau-hardened) ua rau lub sijhawm ntev ntawm kev sib tsoo profile. qhov no txo ​​qis txij nkawm downtime thiab ncua tag nrho cov kev pab cuam lub neej ntawm tus qauv ntev ntawm a100 rail.

• Kuv tuaj yeem siv lub tsheb me me yog tias cov khoom muaj zog dua?

tsis tshua muaj. rail xaiv yog nyob ntawm lub log txoj kab uas hla thiab lub hauv paus siab. cov khoom muaj zog nyob rau hauv ib qho profile me me (xws li a75) tuaj yeem tiv taus hnav, tab sis nws yuav tsis muab qhov kev ruaj ntseg sab nraud lossis thauj khoom faib ntawm 200mm puag ntawm a100.

• Yuav ua li cas yog tias cov khoom siv tsheb ciav hlau muaj zog dua li lub log crane?

Qhov no tuaj yeem ua rau nrawm hnav ntawm lub log crane. Nws yog ib qho kev xyaum zoo tshaj plaws kom phim lub hardness ntawm txoj kev tsheb ciav hlau mus rau lub hardness ntawm lub log kom ntseeg tau tias tag nrho cov kev lag luam rail system hnav ntawm tus nqi kwv yees thiab sib npaug.
