nodular iron casting

Internal shrinkage porosity and shrinkage cavity defects of nodular iron castings are common problems in the casting industry, and how

Through the comprehensive analysis and judgment of the defects after the actual production of nodular iron castings and the CAE

The original process scheme of nodular cast iron is shown in Figure 1, with two pieces in one box. It

Austenite and graphite will precipitate in the solidification process of nodular iron casting. The crystallization of austenite will cause shrinkage,

In the solidification process of Hypereutectic nodular iron casting, when the temperature is lower than the graphite liquidus, the primary

There are two process schemes of low-temperature fast casting and high-temperature slow casting for nodular iron castings of wind power

The influence of carbon and silicon content on the quality of nodular iron castings is shown in the figure below:

In order to reconfirm the defects of the nodular iron casting and the rationality of the analysis results, the CAE

After the casting spheroidization problem appeared, our company’s technical, quality, physical and chemical department and other departments jointly analyzed, according

After the occurrence of bad nodularity, our plant strengthened the detection of sulfur in the original molten iron and the

In the production process of nodular iron castings, in order to ensure the product quality, the tensile strength, yield strength,

The graphite of ball milled cast iron exists in the form of spheroid, which reduces the cleavage effect on the
