Abstract:
An apparatus for manufacturing reaction bonded silicon carbide which comprises:a reactor having an entrance on one side thereof for inserting a carbon preform therein and an exit on the opposite side for discharging reaction bonded silicon carbide therefrom;a carbon woven fabric which moves at constant speed inside the reactor;a transfer apparatus which continuously moves the carbon woven fabric;a molten metal supplier which provides molten silicon and a silicon-molybdenum alloy to the carbon preform on the carbon woven fabric through a pyro-carbon coated dense graphite feeder;the pyro-carbon coated dense graphite feeder located between the molten metal supplier and the carbon woven fabric, the pyro-carbon coated dense graphite feeder having a transfer path through which the molten silicon and silicon-molybdenum alloy are supplied to the carbon preform conveyed on the carbon woven fabric whereby the reaction bonded silicon carbide is formed; andan excess molten metal remover which removes excess silicon and silicon-molybdenum alloy which infiltrates into the reaction bonded silicon carbide.
