Application range of spheroidizing agent——cast iron casting field：
Low-magnesium series spheroidizing agents, with magnesium content of 4%, 5%, 5.5%, RE between 1% and 2%, are mostly used for smelting in intermediate frequency furnaces and spheroidizing of low-sulfur molten iron. It has the advantages of gentle spheroidization reaction and easy absorption of spheroidizing elements.
Medium magnesium series spheroidizing agent, containing 6% and 7% of magnesium, is mostly used in cupola, electric furnace double smelting, or intermediate frequency furnace smelting pearlite cast ductile iron castings. According to the casting wall thickness and the sulfur content of the original molten iron, determine the appropriate amount of spheroidizing agent, which has a wide range of applications and a wide range of spheroidizing treatment processes.
High-magnesium series spheroidizing agent, suitable for cupola smelting, molten iron with sulfur content of 0.06%-0.09%, the addition amount is between 1.6%-2.0%.
Low-aluminum spheroidizing agent is suitable for castings that are prone to subcutaneous pore defects and castings that require aluminum content in molten iron.
The spheroidizing agent produced by pure Ce and pure La has less pure inclusions in the molten iron after spheroidization, and the graphite balls are round. Sb-containing spheroidizing agent is used for pearlitic nodular cast iron; low-silicon spheroidizing agent is suitable for foundry plants that use a large amount of recycled materials; nickel-magnesium spheroidizing agent is used for high-nickel austenitic nodular cast iron. The spheroidizing agent produced by Nanjing Difeng Composite Material Co., Ltd. is suitable for large-section castings, delaying the spheroidization recession and preventing massive graphite.
