Spheroidizing Agent
Nodulizing agent is an additive used in the process of nodular cast iron and vermicular cast iron. It is added to the molten iron to make the graphite in the molten iron solidified into spherical precipitation. In this process, the fine ore powder and concentrate are consolidated through smelting, sintering, granulation, or briquetting. Spheroidizing agent improves metallurgical performance and changes chemical composition of ore; It removes harmful impurities, such as sulfur and volatile gases, and increases reducibility. The use of spheroidizing agent increases the mechanical strength of the ore and makes the ore obtain a porous structure.

Product Description
Nodulizing agent is an additive used in the process of nodular cast iron and vermicular cast iron. It is added to the molten iron to make the graphite in the molten iron solidified into spherical precipitation. In this process, the fine ore powder and concentrate are consolidated through smelting, sintering, granulation, or briquetting. Spheroidizing agent improves metallurgical performance and changes chemical composition of ore; It removes harmful impurities, such as sulfur and volatile gases, and increases reducibility. The use of spheroidizing agent increases the mechanical strength of the ore and makes the ore obtain a porous structure.
The nodulizing agent produced by our company has dense structure, uniform composition, no segregation and low MGO content; The spheroidizing reaction is stable, the magnesium absorption rate is high, and the explosion time is long (1.5-2 minutes); After spheroidizing treatment, the graphite sphere has small diameter, good roundness and high spheroidizing rate. Spheroidizing agent with special composition requirements can be produced according to user requirements.
