Lub excavator boom cam khwb cia steel rooj yog acore hnyav-lub luag haujlwm hinged cam khwb cia hlau ib feemntawm excavator ua hauj lwm ntaus ntawv. Nws yog integrally cam khwb cia thiab mas welded thiab assembled rau lub ntsiab lub cev ntawm lub excavator boom. Ua hauj lwm raws li qhov tseem ceeb load- bearing puag rau pob khawm sib txuas ntawm boom pin shafts, hydraulic cylinders thiab caj npab txuas, nws tiv taus kev khiav hauj lwm cuam tshuam, alternating loads thiab torsional loads.
Nws yog tsim los ntawm engineering carbon cam khwb cia hlau, uas feem ntau siv lub teb chaws tus qauv qibZG230-450thiabZG270-500.
Cov qib sib npaug European thiab Asmeskas cov qauv yog raws li hauv qab no:
European Standard: GP240GH, C25 engineering carbon cam khwb cia hlau
American Standard: ASTM A216 WCB carbon cam khwb cia hlau (feem ntau siv sib npaug qib)
Cov khoom ntasiab zog, zoo toughness, zoo heev weldability, zoo cuam tshuam kuj thiab qaug zog kuj, zoo kawg nkaus yoog rau ntawm - qhov chaw vuam tej yam kev mob ntawm boom. Tom qab normalizing / annealing tshav kub kho, lub sab hauv microstructure yog ntom, tsis muaj teeb meem xws li shrinkage kab noj hniav, porosity thiab tawg.
Cov txheej txheem cam khwb cia ib txwm hloov cov ntaub ntawv welding, featuring uniform kev nyuaj siab tis thiab siab tsis kam mus tawg thiab deformation. Nws hloov mus rau kev ua haujlwm hnyav xws li mining, av ua haujlwm thiab hnyav- thauj cov chaw tsim kho rau excavators ntawm tag nrho cov tonnages, thiab ua raws li cov khoom tseem ceeb rau kev nyab xeeb thiab kev pabcuam lub neej txuas ntxiv ntawm excavator boom.
