The manner which supplies the melting cast iron which for the casting which solidifies as a compressed graphite cast iron was preliminary treated

摘要

(57) Abstract It produces the melting cast iron (CGI), it introduces the medicine which adjusts the graphitization potential of the cast iron into hot water, if necessity, approximately 0.025 weight % it desulfurizes the melting iron to below, transports the melting iron to the kondeishiyoningu reactor, regarding the said reactor, the tonnage of the melting iron, containment within the limit which is decided beforehand by displacement the iron which the hot spring is done at the compensating tonnage of the melting cast iron from the kondeishiyoningu reactor, the mold or it takes the melting iron and, injects to the pot, at the same time from that taking pot injects to the mold, and, adding the graphite form revised medicine and the inoculation medicineIt does, the sample of the melting iron is picked before the above-mentioned note hot water from the mold with that, system of graphitization potential and the iron molding which the temperature variation with the time when the sample the container that containment, in the center of the sample and while recording the temperature variation with the time of the melting cast iron which is the quite vicinity of the wall of the sample container, solidifies the sample from a kind of state where at temperature above crystallization temperature it is substantially relation of heat balance, at the same time, is recorded decide the graphitization potential of property and the cast iron regarding system with known manner, at the same time, are decidedWhen property above deflection having done from known property of the compressed graphite cast iron, you adjust the tonnage of the graphitization potential control medicine in the relation to which the said deflection is beforehand decided, or you adjust the tonnage of the graphite form improvement medicine which it is added or is removed, or you consist of the fact that the tonnage of the inoculation medicine which is added is adjusted, compressed graphite cast doing, the manner which supplies the melting iron which for the casting which solidifies was preliminary treated continually.
