澳门威斯尼斯人网址告诉你铝合金裂纹产生的原因是什么?

来源:

  铝型材的裂纹是由于拉伸应力引起的表面不同程度的横向撕裂引起的。澳门威斯尼斯人网址经过分析,造成这种现象的主要原因如下:
  The cracks of aluminum profiles are caused by different degrees of transverse tears on the surface caused by tensile stress. After analysis, the main reasons for this phenomenon are as follows:
  首先,由于摩擦,金属表面受到附加拉应力的作用。当附加拉伸应力大于金属表面的拉伸强度时,就会产生裂纹。
  Firstly, due to friction, the metal surface is affected by additional tensile stress. When the additional tensile stress is greater than the tensile strength of the metal surface, cracks will occur.

  第二,挤压温度过高,金属表面抗拉强度下降,在摩擦作用下产生裂纹。
  Secondly, when the extrusion temperature is too high, the tensile strength of the metal surface decreases and cracks are produced under the action of friction.
  第三,当挤压速度过快时,金属表面通过加加拉应力来增大型材产生裂纹。
  Third, when the extrusion speed is too fast, the metal surface cracks by adding tensile stress.
  要解决这一问题,只有严格控制挤出工艺参数,保证合理的出口速度和出口温度,才能减少裂纹现象。这就要求威斯尼斯人对生产过程进行严格的检查和监督。
  In order to solve this problem, the crack can be reduced only by strictly controlling the extrusion process parameters and ensuring the reasonable exit speed and temperature. This requires the company to strictly inspect and supervise the production process.
