Other Effects of Silicon in Cast Iron

Silicon dissolved in liquid cast iron greatly enhances the oxidation resistance of molten iron, and silicon can also reduce the solubility of nitrogen in molten iron. Among all kinds of casting alloys, only cast iron can be smelted in an oxygen-rich and nitrogen-rich atmosphere by smelting equipment such as cupolas and oxygen rotary furnaces, precisely because of this effect of silicon.

Increasing the silicon content in cast iron to more than 3.5% will greatly improve the oxidation resistance and thermal growth resistance of cast iron. In the early stage, the trademarks of silicon-based heat-resistant cast iron were included in the standards of heat-resistant cast iron in various countries.

In recent years, for the consideration of energy saving, various internal combustion engines have increased the exhaust temperature. In the automobile industry of various countries, the application of heat-resistant silicon-platinum ductile iron castings and the application of silicon solid solution strengthening effect are very important.

In recent years, the solid-solution strengthening effect of silicon in ductile iron has gradually received widespread attention, but in fact, my country has done some research and application on the solid-solution strengthening of gray cast iron more than 30 years ago, and silicon in gray cast iron solid solution strengthening effect.

Solid solution strengthening effect of silicon in ductile iron.

In recent years, in addition to the increasing requirements for the functions of iron castings, there are also increased requirements for lightweight, low cost, energy saving and emission reduction, and resource conservation. Therefore, the foundry industry of various countries pays great attention to the research and development of improving cast iron materials, especially the research and application of silicon in cast iron and its mechanism.
