Today we will talk about:
the advantages of silicon strontium inoculants
Cast iron is an iron-carbon alloy with
a carbon content greater than 2.1%,
and gray cast iron is a kind of cast iron.
The graphite in gray cast iron is lamellar,
and the fracture is dark gray.
The main components of gray cast iron are iron, carbon, silicon,
manganese, sulfur, and phosphorus, and the cost is low,
and the casting performance and performance are good.
Its output accounts for more than 80% of the total output of cast iron.
With the development of industrial technology,
the requirements for the mechanical properties of
cast iron are getting higher and higher.
The main ways to improve the mechanical properties of
cast iron materials are as follows:
1. Change the carbon equivalent of cast iron;
2. Silicon strontium inoculant inoculation treatment;
3. Heat treatment;
4. Alloying treatment.
The inoculation treatment is a simple,
economical and effective method.
The role of inoculation treatment is to change
the solidification conditions of eutectic crystallization of cast iron,
to achieve the purpose of eliminating white mouth,
promoting graphitization, refining grains,
and improving the uniformity of structure,
thereby improving the mechanical properties
and processing performance of cast iron.
