The casting filter produced by the filter screen custom manufacturer has the advantages of strong wear resistance, large overflow area, accurate temperature resistance, corrosion resistance, aging resistance, long use time, easy replacement, environmental protection and reliability, etc., the mesh and material of the screen are determined according to different use conditions and uses, the filtration accuracy is relatively stable, the compressive strength is high, the straightness is good, there is no excess burr, high temperature resistance, fast cold and heat resistance, and it is suitable for high-pressure environment.
In casting, non-ferrous metals and ferrous metal castings such as iron castings, steel castings, copper castings and aluminum castings are prone to defects such as slag holes, sand holes, and pores due to various reasons, therefore, the use of casting filter screen to remove non-metallic inclusions in molten metal, improve the yield of castings, and improve the quality of castings have important technical requirements and economic value, and the specific purposes are as follows:
1. Effectively remove harmful impurities such as bubbles, oxidized ash slag and various inclusions in the metal melt, so as to fundamentally reduce the porosity, slag holes, sand holes and other defects of castings, greatly improve the yield of castings, and improve the internal and external quality of castings.
2. Improve the mechanical properties of castings: It can increase the hardness of castings, the surface hardness is uniform, and the flexural strength of castings can be improved.
3. Change the graphite properties of the casting, so that the graphite size is reduced, the thickness is thinner, and the shape is slightly curved, which is more conducive to the mechanical properties of the casting.
4. Use casting filter to change the processing performance of castings, improve processing efficiency, and reduce machining loss.
The casting filter can effectively remove harmless impurities such as bubbles, oxidized ash, and various inclusions in the molten metal, greatly improve the yield and quality of the casting, prevent other metal components from penetrating into the molten metal and affect the metallographic of the alloy, so as to ensure the quality of the casting, and also improve the mechanical properties of the casting: it can improve the hardness of the casting, the contour hardness of the casting is uniform, and the flexural strength of the casting is improved.
