Product material characteristics
Mechanical properties
The mechanical properties of gray cast iron are related to the structure of the matrix and the shape of graphite. The flake graphite in gray cast iron severely splits the matrix, and it is easy to cause stress concentration at the sharp corners of the graphite. The tensile strength, plasticity and toughness of gray cast iron are much lower than steel, but the compressive strength is equivalent to steel, and it is also commonly used cast iron. Cast iron with the worst mechanical properties among the pieces. At the same time, the matrix structure also has a certain influence on the mechanical properties of gray cast iron. The graphite flakes of ferrite-based gray cast iron have the lowest strength and hardness, so it is less used; the graphite flakes of pearlite-based gray cast iron are small and have higher The strength and hardness are mainly used to make more important castings; the graphite flakes of ferrite-pearlite matrix gray cast iron are slightly larger than pearlite gray cast iron, and the performance is not as good as pearlite gray cast iron. Therefore, gray cast iron with a pearlite matrix is more commonly used in the industry.
Other properties
Gray cast iron has good casting performance, good vibration damping, good wear resistance, good cutting performance, and low notch sensitivity.
Influencing factors of gray cast iron properties
①The influence of chemical composition. The production is mainly to control the mass fraction of carbon and silicon. If the mass fraction of carbon and silicon is too low, the cast iron is prone to white-mouth structure, and the mechanical properties and casting properties are very low; when the mass fraction of carbon and silicon is too high, the graphite flakes are too large and thick, and even graphite floats on the surface of the molten iron. Reduce the performance and quality of castings. Therefore, the carbon and silicon content in gray cast iron is generally controlled at 2%～4%C; 1.0%～2.0%Si; 0.5%～1.4%Mn.
②The influence of cooling rate: Under certain casting process conditions, the cooling rate of castings has a great influence on the degree of graphite formation. As the wall thickness of the casting increases, the cooling rate slows down, and the carbon atoms have sufficient diffusion time, which is conducive to the full progress of the graphitization process. The room temperature structure is easy to form a gray iron structure; but the thin-walled parts are cold during the cooling process. If the speed is too fast, it is easy to form a white iron structure.
