Cov khoom siv zoo tshaj plaws rau cov nruas nres yog nyob ntawm cov ntawv thov tshwj xeeb thiab kev ua haujlwm tau zoo. Tam sim no, cov ntaub ntawv tseem ceeb yog cam khwb cia hlau (grey cam khwb cia hlau los yog alloy cam khwb cia hlau) thiab cov ntaub ntawv sib xyaw (xws li carbon ceramic). Nov yog ib qho kev ntsuam xyuas ntxaws:
Cov khoom siv hlau
Grey Cam khwb cia hlau (HT250): Tus nqi qis, hnav tsis kam, haum rau cov neeg caij tsheb zoo tib yam thiab cov tsheb lag luam, tab sis nws muaj cua sov ploj ntawm qhov kub thiab txias.
Alloy Cast Iron: Ntxiv cov khoom xws li chromium thiab molybdenum txhim kho qhov kub thiab txias (kev ua haujlwm kub txog li 500 degree), haum rau hnyav - tsheb thauj mus los lossis nquag nres xwm txheej.
Cov khoom siv sib xyaw
Carbon Ceramic (C/SiC): Lightweight (more than 50% lighter than cast iron), high temperature resistant (>1000℃), tab sis kim heev, feem ntau yog siv nyob rau hauv siab -kev ua si tsheb los yog kev sib tw tsheb.
