What should be noted in the standard production process of cast iron platforms

As a traditional metal forming industry, casting is gradually integrating materials and technologies from other industries with the continuous development of technology, and is also undergoing transformation and growth. The composition and properties of future raw materials, including pig iron, scrap steel, and recycled steel, as well as a series of reactions that occur during the melting process to form molten iron, which then goes through various stages such as filling, cooling, solidification, and cooling, will be clearly understood by the industry. In terms of pattern manufacturing, cast iron platforms will also replace traditional wood with materials such as resin and steel, and the structure of platform castings will also be improved. These are the future development trends and directions of cast iron platforms, which will also have an impact on energy and material conservation in cast iron platform casting.

In practical production, corresponding processes should be developed based on the structural characteristics of each cast iron platform casting. There are mainly slender shapes with a designed deformation amount. The sand core in the middle cavity of this casting has good universality and can reduce the number of core boxes; When the center hole of the circular platform casting is large, the circular sand mold of the center hole can be divided into 1/2 or 1/4 to reduce the size of the core box. As for the fan-shaped core on the periphery, it also has high versatility.

Improving quality is a good energy-saving material. There are many production processes and influencing factors in casting, and quality control is difficult, especially for large platforms, which have high requirements in terms of tooling, molding technology, and melting. Every detail needs to be handled well. Especially the quality of molten iron is crucial for the success or failure of platform casting production. In addition to meeting the material grade requirements, the temperature and properties of molten iron also have an impact on the casting.

The process of using the lost foam casting cast iron platform is as follows: selecting foam beads - model making - model combination into clusters - model coating - vibration modeling - pouring replacement - cooling and cleaning. Lost foam casting has the characteristics of unlimited material, smooth surface, few internal defects, easy assembly line operation, low cost, and good casting quality.
