来源:http://www.jnhjgs.cn     发布时间:2021-07-12 11:53:03    点击:

为了提高山东铝合金压铸件的性能,必 须处理铸件的表面粗糙度。该方法是针对影响铝合金压铸件粗糙度的因素采取相应的处理措施。那么如何处理铝合金压铸件的表面粗糙度问题呢?
In order to improve the properties of Shandong Aluminum alloy die castings, the surface roughness of the castings must be treated. This method is to take corresponding measures to deal with the factors that affect the roughness of aluminum alloy die castings. So how to deal with the surface roughness of aluminum alloy die casting?
1.使用耐火度高的细粒原砂
1. Use fine sand with high fire resistance
2.使用再生砂时,去除太细的砂粒,烧死的粘土,灰烬,金属氧化物,废金属,铁包砂和其他有害杂质,以改善再生砂的质量。定期添加适量的新砂
2. When using recycled sand, remove too fine sand, burnt clay, ash, metal oxide, scrap metal, iron coated sand and other harmful impurities to improve the quality of recycled sand. Add appropriate amount of new sand regularly
3.水是强氧化剂。应严格控制绿砂的水分,并应加入适量的煤粉,沥青,碳氢化合物和其他含碳物质,以在砂中形成还原性气氛。但是,在高压建模期间应减少碳质材料的量,以减少产生的气体量。
3. Water is a strong oxidant. The moisture content of green sand should be strictly controlled, and appropriate amount of coal powder, asphalt, hydrocarbon and other carbonaceous substances should be added to form reducing atmosphere in the sand. However, the amount of carbonaceous material should be reduced during high pressure modeling to reduce the amount of gas produced.
4.适当降低浇注温度,浇注速度和浇注高度,减少上模高度和浇口杯高度,以减少金属液压,静压力和对beplay全站app安卓的热冲击
4. Properly reduce the pouring temperature, pouring speed and pouring height, reduce the height of the upper mold and the height of the gate cup, so as to reduce the metal hydraulic pressure, static pressure and thermal impact on the mold

5.加强铸钢和其他高熔点合金的精炼,净化熔融金属,降低合金液中的氧化度和气体含量,并减少低熔点相形成元素(如硫和磷)。铸钢和铸铁以及青铜中的磷控制元素的含量(例如铸钢和铸铁中的锰和硅以及青铜中的铅),可以降低熔融金属的表面张力并增加金属的蒸气压。熔融金属。
5. Strengthen the refining of cast steel and other high melting point alloys, purify the molten metal, reduce the oxidation degree and gas content in the alloy liquid, and reduce the forming elements of low melting point phase (such as sulfur and phosphorus). Phosphorus control elements in cast steel and cast iron and bronze (such as manganese and silicon in cast steel and cast iron and lead in bronze) can reduce the surface tension of molten metal and increase the vapor pressure of metal. Molten metal.
6.对于大型厚壁铝合金压铸件,及早打开包装盒以加快铸件的冷却速度,以防止固体沙粒粘连。使用光滑的表面和芯盒。
6. For large thick wall aluminum alloy die castings, open the packing box as soon as possible to speed up the cooling speed of the castings, so as to prevent solid sand adhesion. Use smooth surface and core box.
铝合金压铸件的表面粗糙度对铸件的使用影响很大,因此必 须及时解决影响铝合金压铸件表面粗糙度的因素,以提高铝合金压铸件的质量和性能。
The surface roughness of aluminum alloy die castings has a great influence on the use of castings. Therefore, the factors affecting the surface roughness of aluminum alloy die castings must be solved in time to improve the quality and performance of aluminum alloy die castings.
