How to solve the factors influencing the casting

Foundry industry is an ancient and emerging industries, is the basis of the mechanical industry and manufacturing industry, determines the service life of mechanical equipment and a variety of production equipment and robustness. After thousands of years of production practice and experience, in-depth scientific research from the understanding of the surface to the microscopic theory has made great development, constantly improve the casting issues during production process, stability to complete the analysis and control of technical parameters, can make the castings beautification, thereby ensuring the service life of mechanical equipment and robustness. To produce qualified and high quality castings, must first to understand and study the various factors influencing the performances of cast iron, how to improve the smelting purity of molten iron and how to form good graphite morphology and control chemical composition range, etc., are all important factors. Study to solve the above problem can achieve a goal. Hot metal purity affected factors:
1. Control elements oxidation burning loss of oxide inclusions emissions;
2. The sulfur content of the control, prevent the formation of sulfur eutectic;
3. Solve the melting oxygen smelting of porosity;
4. Trace elements under interference quantity restrictions
5. Control of phosphorus content, prevent the formation of phosphor eutectic.
