青岛弹簧厂告诉您温度是如何影响弹簧质量的

      要想弹簧能在高温下稳定工作,需要它有强度非常好的抗松驰性、热稳定性以及抗氧化的能力,还要有一定的耐腐蚀能力。这是为什么呢?
    In order to work steadily at high temperature, it is necessary for the spring to have excellent anti-relaxation, thermal stability and anti-oxidation ability, as well as a certain corrosion resistance. Why is that?
    因为如果弹簧工作的温度很高,那制作弹簧的材料的弹性模量会随着下降,这就会导至弹簧的承载力变小和刚度下降。所以,要使它能在高温下工作我们需要知道它的变化率,还需要计算出下降的承载能力对弹簧使用性能影响。按照相关规定,一般的弹簧如果工作时的温度比60度高时,需要对它切变的模量有一定的调整。
    Because if the temperature of the spring is very high, the elastic modulus of the material used to make the spring will decrease, which will lead to the decrease of the bearing capacity and stiffness of the spring. Therefore, in order to make it work at high temperature, we need to know its rate of change, and also need to calculate the impact of reduced load capacity on spring performance. According to the relevant regulations, if the temperature of a general spring is higher than 60 degrees, it is necessary to adjust its shear modulus.
  
    使用弹簧钢来制作弹簧,选择时要根据弹簧所承载的应力大小和它的性质来判断它硬度,但是,如果出现平面的应变断裂,那就可能说明是由于硬度的原因造成的。
  
    Spring steel is used to make springs. The hardness of the springs should be judged according to the magnitude of the stress and the nature of the springs. However, if plane strain fracture occurs, it may be explained that it is caused by the hardness.
  
    如果把弹簧用在仪器或者是衡器里面,大部分厂家会使用恒弹性合金,因为它的膨胀系数变化非常小,这也是为了满足它的精度不受气温的变化。
  
    If springs are used in instruments or weighing instruments, most manufacturers will use constant elastic alloys, because the coefficient of expansion changes very little, which is also to meet its accuracy is not subject to changes in temperature.
  
    在进行材料选择时候,钢材的淬透性能是需要注意的,这点对弹簧的质量关系比较大。
  
    When choosing materials, the hardenability of steel should be noticed, which has a great relationship with the quality of spring.
  
    弹簧厂家面对影响弹簧质量的问题,有好的技术、环境条件处理,使产品质量达到客户需要。
  
    Spring manufacturers have better technology and environmental conditions to deal with the problems affecting the quality of springs, so that the quality of products can meet the needs of customers.
