铝合金压铸凝固点的技术需求?

来源:http://www.jnhjgs.cn     发布时间:2020-03-16 15:01:23    点击:

铝合金铸件是一种以铝为主要金属元素的构件铸件,它还含有其他金属元素。铝合金压铸厂家从事合金铸件的生产加工,对铸件的凝固特性有很好的了解。
  Aluminum alloy casting is a kind of component casting with aluminum as the main metal element, it also contains other metal elements. Aluminum alloy die casting manufacturers are engaged in the production and processing of alloy castings, and have a good understanding of the solidification characteristics of castings.
  铝合金铸件的强度高于纯铝。根据铝合金压铸厂的介绍,两种非完全固溶体金属的熔合通常有一种共晶成分,其凝固点比任何一种成分都低。在含硅铝合金中,当硅含量达到11.7%时发生共晶。此时合金的熔点比铝低100℃,比硅高850℃。
  The strength of aluminum alloy casting is higher than that of pure aluminum. According to the introduction of aluminum alloy die casting plant, there is usually one eutectic composition in the fusion of two kinds of incomplete solid solution metals, and its freezing point is lower than any other composition. In the aluminum alloy containing silicon, eutectic occurs when the silicon content reaches 11.7%. The melting point of the alloy is 100 ℃ lower than that of aluminum and 850 ℃ higher than that of silicon.

  共晶铝硅合金除了具有两相均相机械混合的结构特点外,其熔点较低,比熔点较高的合金使用寿命更长。在处理这类合金,铝合金压铸厂家应注意增加在凝固温度梯度,使过渡粘贴区域相应缩小,并应用高压喷射的阶段,这有利于压铸收缩。
  In addition to the mechanical mixing of two phases, the eutectic Al Si alloy has a lower melting point and a longer service life than the alloy with a higher melting point. In the treatment of this kind of alloy, aluminum alloy die-casting manufacturers should pay attention to increase the solidification temperature gradient, so that the transition bonding area is correspondingly reduced, and the application of high-pressure jet in the final stage is conducive to die-casting shrinkage.
