machine tools. The decarburization

machine tools. The decarburization seems to be mainly the result of oxidation of the carbon by water
vapor since dry molds reduce the problem. An addition of 5 or 6% coal dust to the mold further reduces
it. Rickards (1975) found that the reaction seems to start at about the freezing point of the eutectic,
about 1150


C, and proceeds little further after the casting has cooled to 1050


C (Figure 4.12).

peralatan mesin. Dekarburisasi tampaknya terutama hasil dari oksidasi karbon dengan air
uap sejak cetakan kering mengurangi masalah. Tambahan debu batubara 5 atau 6% untuk cetakan lebih lanjut mengurangi
itu. Rickards (1975) menemukan bahwa reaksi tampaknya mulai sekitar titik beku eutektik,
sekitar 1.150
