Product Description
Nodularizer
The additive that causes the graphite in cast iron to crystallize into a spherical form is called a "nodularizer." The main components of a "nodularizer" are nodulizing elements, such as Mg, Ce, Ca, etc. The spherical graphite in ductile iron is formed after the molten iron is treated with a nodularizer, which significantly increases its strength compared to gray cast iron and provides better toughness than malleable cast iron, while still retaining a series of advantages of gray cast iron.
In China, the commonly used nodularizer is ferrosilicon rare earth magnesium alloy, while most foreign countries use magnesium-based nodularizer (pure magnesium and magnesium alloys), and a few countries use calcium-based nodularizer.
The basic requirements for a nodularizer are:
1. Strong nodularizer capability;
2. Abundant resources, low cost, and ease of melting;
3. Strong adaptability to molten iron with various compositions (such as degree of eutecticity, sulfur content, anti-nodularizer elements, and alloying elements) and temperatures;
4. Good kinetics for nodularizer reactions, relatively stable reactions, easy removal of reaction products, low usage, minimal temperature drop, and good nodularizer treatment processability.
Silicon-Magnesium Alloy
Silicon-magnesium alloy is a alloy smelted from ferrosilicon, magnesium, and trace amounts of silicon-calcium and rare earth elements. It is a high-performance nodulizer with strong deoxidizing and desulfurizing capabilities, as well as an excellent nodulizing effect. It is commonly known as the "High-Mg Nodulizer".
Purpose
Primarily used as the core material for cored wire used in nodularizing treatment.
