SiC소결체의 용철중의 용해속도
The Rate of Solution of Sintered SiC by Liquid Iron
철과강, 13. Nov. 19*3, Susumu Minowa, Mineo Kosaka
The rates of solution of the cylindrical sintered silicon carbides by liquid iron that were melted in various furnaces(Tammann furnace and two high-frequency furnaces of different cycles) were measured at temperatures from 1400℃ to 1600℃.
It was found that the rates of solution of SiC bars in liquid iron were markedly influenced
by the concentration of carbon and silicon in the metal and the stirring action of melts.
The diffusion process controls the rate of solution of SiC.
When the sintered SiC sample was immersed in carbon saturated liquid iron and Fe-C-Si melt (C 1.5%,Si=3.0%),the activation energy of solution was as follows,
49~86 Kcal/mol in carbon saturated liquid iron,
53~72 Kcal/mol in Fe-C-Si melt.
