nodular cast iron

At present, the most commonly used spheroidizing agent for nodular cast iron in China is rare earth silicon iron magnesium […]

Both graphite ball and matrix will affect the mechanical properties of nodular cast iron. It is found that with the

Referring to the latest ductile iron standard GB / t1348-2009, the brand, mechanical properties and metallographic structure of ductile iron

According to GB9441-2009 metallographic inspection standard for nodular cast iron, the pearlite content in the as cast matrix is graded.

The spheroidizing treatment process of nodular cast iron mainly includes the types of spheroidizing agent and the adding method of

Through the observation of metallographic photos, the spheroidization level of a1-a8 and B1-B4 and the size level of nodular graphite

The figure shows the change law of impact toughness of nodular cast iron of B2 and B4 samples with temperature.

The figure shows the difference of mechanical properties of nodular cast iron of series a samples under as cast and

In addition to chemical composition, the influence of other production processes mainly refers to the influence of melting process, spheroidizing

Bismuth can significantly increase the number of graphite spheres. When the number of graphite balls in nodular cast iron increases,

The effects of silicon, copper and Bismuth on mechanical properties were analyzed. The figure shows the effect of silicon on

During the sample preparation of nodular cast iron, the discharge temperature, pouring temperature, spheroidizing treatment time and total pouring time

The production process of nodular cast iron to be designed in the experiment mainly includes melting process, molding process, spheroidizing

Trace elements are interfering spheroidizing elements, but due to the neutralization effect of rare earth elements added in production, adding

After spheroidizing treatment, spheroidizing elements will make nodular cast iron have a greater tendency to white. At this time, inoculation

The research on the chemical composition of nodular cast iron provides a reliable basis for the composition design of the

Common alloy elements include nickel, copper, aluminum, chromium, vanadium and other elements. 1.Nickel Nickel is a chemical element commonly used

There are five basic elements: carbon, silicon, manganese, phosphorus and sulfur. 1.Carbon Carbon is the direct source of graphite ball.
