Crane wheels are among the most frequently worn components in lifting equipment. Due to the working conditions of cranes, the wheel tread must have high surface hardness, along with a sufficiently deep hardened and transition layer (depth >10MM, Hardness Hrc 40-48) los txhim kho kev thauj khoom muaj peev xwm, hnav tsis kam, thiab hu rau kev qaug zog ua haujlwm.
Nyob rau tib lub sijhawm, lub cev log yuav tsum muaj muaj zog tag nrho cov khoom siv tshuab thiab cov coj cov khoom siv microstructure. Ib lub zog hardness ntawm HBS 187-229 feem ntau yuav tsum tau ua kom muaj kev cuam tshuam zoo dua thiab txhim kho kev cuam tshuam thiab tawg tawm.
Crane Log Teeb Specifications
Cranes tau tshwj xeeb engineering tshuab siv rau kev nqa khoom thiab thauj cov ntaub ntawv. Tus qauv tsim thiab tsim cov log crane yuav tsum ua raws li kev lag luam qauv jb / t 6392 {{} 2008 rau crane log. Raws li cov load tseem ceeb - lub log sib xyaw ua si lub luag haujlwm tseem ceeb hauv kev ua haujlwm. Yog li ntawd, siv lub log zoo yog qhov tseem ceeb kom paub meej tias kev ua tau zoo thiab kev nyab xeeb.
Cov Khoom Siv & Tsim Tsim Cov Txheej Txheem
Crane log yog feem ntau ua los ntawm cam khwb cia store steel zg430-640 lossis forged steel zoo xws li 60 #, 42crmo, lossis 65mn. Txhawm rau txhim kho cov coj tsis kam, lub log tsuj av saum npoo quenching, ua tiav qhov tawv tawv ntawm HB300-350 nrog qhov tsis muaj tsawg dua 20 hli. Forged log teeb tsa ntxiv txhim kho cov tshuab muaj zog los ntawm kev tsim kho kom zoo li qub los ntawm cov hlau forging.
Log Ntau Hom
Crane log yog categorized los ntawm cov qauv npoo rau hauv peb hom: Rimless lub log, ib leeg fange log, thiab ob npaug {1} {flange log.
Daim Ntawv Thov Kev Pab Cuam
Lub log log tau siv dav hauv Gantry Cranes, ob {-} Girtry cranes, nrog rau cov stackers. Ib Leeg - flange log feem ntau siv rau lub teeb {{flange log tau zoo dua rau hnyav {5} thauj khoom siv.
Hlau Yuav Tsum Tau
1.Qhov cov khoom siv cov qib rau dov lub tsev hubs yuav tsum tsis txhob qis dua 60 tus hlau raws li teev hauv GB / T 699.
2.Qhov kev ntxhov siab yuav tsum tau tshem tawm thaum lub sijhawm tsim khoom. Rau cam khwb cia steel log, annealing yuav tsum tau ua ua ntej kev siv lub tshuab ua kom daws kev ntxhov siab sab hauv, tom qab los ntawm cov xuab zeb ntxuav.
3.Qhov kev pheej hmoo siab txog lub log ua kom yuam kev yuav tsum tau ua raws li qib H9 raws li txhais hauv GB / T 1801-1999.
4.Qhov kev siv log yuav tsum yog qhov tsis pom kev sib tsoo.
5. Tsis muaj vuam yog tso cai rau qhov tsis xws luag pom ntawm lub tsuj taw lossis sab hauv ntawm lub log flange.
6.Cov txiav saum cov tshuab sib tsoo yuav tsum muaj kev tiv thaiv siv anti- xeb roj.
