During the casting process, the main purpose of using casting filters is to improve the quality of metal liquids, reduce defects and improve the overall performance of castings.
These casting filter meshes are generally suitable for the following types of metal liquids:
- Molten iron (cast iron liquid): Molten iron often needs to be filtered during the casting process to remove impurities and bubbles and improve the quality of castings.
- Molten steel: Molten steel is a liquid metal used to produce steel castings. Filter meshes can help remove impurities in molten steel and improve the mechanical properties of castings.
- Molten aluminum alloy: Aluminum alloy also needs to be filtered during the casting process to ensure a smooth surface of the casting and reduce pores and defects.
- Molten copper alloy: Copper alloy liquid also needs to be filtered during the casting process to improve the density and strength of the casting.
- Other non-ferrous metal liquids: Filter meshes can also be used to filter other non-ferrous metal liquids, such as magnesium alloys, zinc alloys, etc.
The design and material selection of these filter meshes can usually adapt to the filtering needs of different types of metal liquids and improve the quality and performance of castings.
Here are some of the main reasons why filters are needed in casting:
- Remove impurities: Liquid metal is easily contaminated by external impurities such as oxides, sand particles, metal chips, etc. during the flow and casting process. Filters can effectively remove these impurities and make the liquid metal purer.
- Reduce pores: Gas in liquid metal is prone to form pores during solidification. Filters can help eliminate gas bubbles, reduce pores on the surface and inside of castings, and improve the density and strength of castings.
- Improve surface quality: Filters can filter out oxide scale and impurities on the surface of liquid metal, making the surface of castings smoother, reducing defects and pores, and improving surface quality.
- Improve mechanical properties: By removing impurities and pores through filters, the mechanical properties of castings, such as strength, toughness and wear resistance, can be improved, making castings more in line with design requirements.
- Improve the qualified rate of castings: Using filters can reduce the defect rate of castings, improve the qualified rate of castings, and reduce production costs.
In general, filters play a key role in the casting process, helping to produce high-quality castings, improve production efficiency, and reduce production costs.
Common castings using casting filters:
These casting filters are generally suitable for various types of castings, including but not limited to the following:
- Engine blocks and cylinder heads: Cylinder blocks and cylinder heads in engine parts usually require a high-quality casting process, and filter meshes can help remove impurities and improve the density and wear resistance of castings.
- Automotive parts: For parts such as crankshafts, connecting rods, exhaust pipes, etc. of automobile engines, filter meshes can help improve the surface quality and mechanical properties of castings.
- Engineering machinery parts: For example, excavator parts, loader parts, etc., the casting quality of these large mechanical parts directly affects the performance of the entire mechanical equipment.
- Pipes and valves: Castings for industrial pipes and valves require a high-quality casting process to ensure sealing and durability.
- Aerospace parts: Parts in the aerospace field have very high requirements for materials and quality, and filter meshes can play a key role in casting these parts.
- Agricultural machinery parts: Such as tractor parts, harvester parts, etc., require high-quality casting to ensure their reliability in harsh environments.
These filter meshes play a key role in the production of different types of castings, helping to improve the quality of castings, reduce defects, and optimize production processes.
