In order to obtain ADI material with stable structure and performance, the salt bath used for isothermal transformation should have the following characteristics: ① The salt bath shall be equipped with a device to prevent local overheating or local supercooling of salt bath to ensure the temperature of each...
Inoculation treatment: inoculation treatment of nodular cast iron can improve the roundness of graphite ball, improve the spheroidization rate, and assist the spheroidal growth of graphite. Inoculation is an important means to increase the number of graphite balls, and the number of graphite spheres has an important effect on...
The common graphite forms in spheroidal graphite iron contain globular graphite type, quasi-spherical temper graphite type, interdendritic graphite type and worm graphite type and etc.. The most representative one among all of them is globular graphite structure. Its appearance is roughly spherical in low power and is close to...
