Kev xaiv ntawm hlau rau lub pob txha nres yog qhov tseem ceeb heev. Feem ntau, cov ntaub ntawv zoo li nruab nrab - Carbon Steel thiab Alloy Steel tau txiav txim siab. Nruab Nrab - Carbon Steel, xws li 45 -} steel, muaj cov khoom siv zoo thiab yog pheej yig. Nws tuaj yeem muab lub zog txaus thiab tawv rau cov haujlwm ua haujlwm ib txwm muaj.
Txawm li cas los xij, rau siab - kev ua tau nres Camshafts, cov hlau Alloy zoo li chromium - molybdenum hlau siv. Cov txheej txheem sib xyaw no muaj cov kub ua kom zoo, hnav tsis kam, thiab qaug zog tsis kam. Qhov sib ntxiv ntawm cov ntsiab lus tseem ceeb txhim kho cov kev ua tau zoo ntawm camshaft, ua rau nws tiv thaiv siab thiab siab - kev nyuaj siab mob thaum lub sij hawm braking.
Cov nqi loj loj feem ntau yog kav los ntawm tus nqi ntawm cov ntaub ntawv raw thiab kev tsim khoom. High - Cov khoom zoo alloy muaj nqi ntau dua vim yog tus nqi ntawm alloy cov ntsiab lus thiab complex smelting txheej txheem. Ntxiv mus, kev tsim cov kev tsim khoom ua ntej xws li kev zam txim sai thiab kev kho cua sov rau Alloy Steel CamShafts tseem ua rau cov nqi ntau dua. Hauv kev sib piv, kev tsim cov camshafts ua los ntawm cov khoom nruab nrab zoo tib yam - cov pa roj carbon hlau yooj yim dua thiab tsawg dua.
