Tsim los ntawm qib siab - qib ductile cam khwb cia hlau los ntawm precision xuab zeb casting, peb cov tsheb ciav hlau lub xub pwg nyom muaj lub zog zoo, durability, thiab zoo ib yam ntawm qhov tseeb rau kev ntseeg tau ntev - lub sij hawm ua haujlwm hauv kev tsheb ciav hlau.
Lub hauv paus ntsiab lus ua haujlwm ntawm lub xub pwg rail yog dab tsi?
Lub xub pwg tsheb ciav hlau yog ib qho cam khwb cia- hlau tivthaiv embedded rau hauv cov pob zeb pw tsaug zog los yog welded rau steel daim hlau, ua raws li ib tug ruaj ntseg thauj tog rau nkoj taw tes rau elastic rail clips. Nws ua haujlwm los ntawm kev muab lub rooj zaum ruaj khov, nruj, thiab ruaj khov rau cov clip kom siv lub zog qis qis, tiv thaiv kev txav mus los thiab kev ruaj ntseg ntawm txoj kev tsheb ciav hlau.
Qhov tseem ceeb ntawm Rail Lub xub pwg ua haujlwm txoj cai:
- Anchorage Point: Nws ua raws li molded los yog cam khwb cia- nyob rau hauv feature uas muab ib tug khoom, immovable taw tes tiv thaiv uas elastic clip exerts nws clamping quab yuam, kom lub clip tuav lub tsheb ciav hlau ko taw ruaj ntseg.
- Load Distribution & Stability: Nws pab tswj qhov ntsuas qhov tseeb (qhov kev ncua deb ntawm txoj hlua) thiab kev sib dhos los ntawm kev muab kev tiv thaiv rau sab nraud tiv thaiv lub zog ntawm cov tsheb ciav hlau hla.
- Component Interaction: Lub xub pwg nyom ua haujlwm ua ke nrog elastic clips, cov ntaub ntawv insulating, thiab cov ntaub qhwv roj hmab los tsim kom muaj kev ruaj khov, ruaj khov, thiab, qee zaum, cov qauv hluav taws xob insulated.
Yuav ua li cas ua Rail Lub xub pwg nyom?
Rail cam khwb cia hlau lub xub pwg nyom yog tsim los ntawm precision xuab zeb casting nrog kev tswj xyuas nruj kom ntseeg tau tias cov khoom siv zoo ib yam thiab qhov tseeb.
- Txheej txheem:Molten hlau (malleable hlau los yog spheroid graphite hlau) yog poured rau hauv pwm los tsim lub xub pwg nyom, uas yog ces embedded rau hauv pob zeb pw thaum lawv tsim.
- Cov txheej txheem:Cov txheej txheem tshwj xeeb xws li Lost Foam thev naus laus zis yog siv rau kev ua haujlwm nyuaj, meej castings.
- Khoom siv:Cov ntaub ntawv muaj xws li MCI (malleable cam khwb cia hlau) lossis SGCI (spheroid graphite cam khwb cia hlau), nrog rau qib steel xws li QT600-3, ZG25, ZG35, thiab ZG45.
