Precision casting processing has also been transformed into large and medium-sized casting processing. The characteristics of casting processing are: because the graphite in pig iron is beneficial to lubricating and oil storage, it has good wear resistance. Similarly, due to the appearance of graphite, the shock absorption is better than that of steel, and due to the high carbon content of gray cast iron, which is close to the carbide composition, the melting point is relatively low, the flowability is excellent, and the shrinkage rate is small, so it is suitable for casting with chaotic structures or thick walls. Casting. In addition, the drillability of gray cast iron is better than that of steel because graphite makes it easy to break during drilling.
Heat treatment of casting processing: As a kind of large and medium-sized casting processing, bed type casting processing products must pass heat treatment to improve their performance indicators and improve the meaning and quality of pig iron casting processing. Heat treatment of metal materials is one of the main processing techniques in mechanical equipment. Compared with other processing techniques, heat treatment generally does not change the shape and overall composition of the workpiece. Instead, it changes the microscope distribution of the internal structure of the workpiece or changes the composition of the workpiece surface , which grants or improves the performance metrics of the artifact. The advantage is to improve the quality of the meaning of the workpiece.
Following the advancement of science and technology, precision casting stainless steel castings are the most common equipment companies in the steel casting industry chain. The production process of stainless steel castings is flexible, and it can be distributed in large quantities for automatic production and manufacturing, and can also use scrap metal raw materials and renewable energy.
