The spheroidizing agent is a gray-black solid, which is made of ferrosilicon as a raw material, and the ratio of calcium, magnesium and rare earth is adjusted to the standard range to make it react smoothly. The casting thickness of each grade of the spheroidizing agent shall not exceed 100mm; The standard particle size of the spheroidizing agent is 5~25mm, 5~30mm. Basic requirements for gliding agents:

(1) Strong spherical ability;

(2) Rich in resources, low price, easy to melt;

(3) Strong adaptability to various components (such as eutecticity, sulfur content, anti-spheroid elements and alloying elements) and temperature of molten iron;

(4) The kinetic conditions of the spheroidization reaction are good, the reaction is relatively stable, the reaction products are easy to exclude, the dosage is small, the cooling is less, and the spheroidization treatment is good.
