Who knows the technology of casting
High temperature fiber casting filter is widely used to filter and purify all kinds of metal melt, and filter through filter net, can achieve the purpose of the following: Effectively remove the air bubbles, soot oxide and various inclusions and other harmful impurities in the molten metal, thus eliminating the air hole of the castings The quality of the castings and the inner quality of the castings are improved. Improving the mechanical properties of castings: it can improve the hardness of castings, and the surface hardness is uniform and the bending strength of the castings is improved. Change the cast graphite form, make the graphite size to be reduced, the thickness is thin, and the shape is slightly curved. Change the machining performance of castings and improve the efficiency of processing.
Casting filter Casting filter in casting production, steel, cast iron, cast aluminum parts and other alloy casting, due to various reasons is easy to produce the quality problems such as slag eye, sand holes, blow hole, therefore remove the non-metallic inclusions in metallic melts, to improve the casting yield, improve casting quality, it is of great technical value and economic value. The casting filter is made of high temperature resistant fiber, which is made by special process weaving and reprocessing, and the product is series, advanced technology and stable quality. Compared with other kinds of filter, high temperature resistant fiber casting filter low cost, easy to use, do not change the casting metal composition, good effect of residue, low gas evolution. In addition, it also has high temperature, corrosion resistance, chemical stability, metal melt, good steel strength. Therefore, the heat-resistant fiber casting filter is the ideal filter material for all kinds of metal melt. It can also be used for the filtration of chemical corrosion liquids and high temperature gases.
(1) can effectively remove the air bubble in the molten aluminum, clamp ash oxide, as well as a variety of harmful impurities such as inclusions, greatly improve the yield of aluminum casting and improving the quality of the aluminum products, and avoid the disadvantages of the other metal elements into aluminum solution, does not affect the aluminum alloy components, to ensure the quality of aluminum castings. Improve the mechanical properties of aluminum casting: it can improve the hardness of casting, and the surface hardness is uniform and the bending strength of the casting is improved. Change the machining performance of castings and improve the efficiency of processing. Compared with all kinds of filter, the high temperature fiber filter does not affect the composition of aluminum alloy. Because fiber itself have the effect of the adsorption of impurities, the filtering effect is better, in addition, that has a high temperature resistant, high temperature resistant fiber filter mesh has good stability, convenient use, and helpful for recycled utilization of waste (waste recycled, in aluminum solution the surface mesh). High temperature fiber filter cloth is an ideal filtration material for high-grade aluminum alloy castings.
