提高成品的尺寸精度是轧制技术发展的重要课题之一。缩小尺寸偏差可以使成品的实际尺寸不断接近于相应标准的最小容许值。这样就可以使成材率显著提高。今后的努力方向是使成品的尺寸精度超过标准要求,以期生产出质量更加优异的成品来。这种提高成材率和改善质量的方法,在钢管生产的发展中也起着特别重要的作用。提高成品管的尺寸精度,首先要把注意力集中在降低壁厚偏差上。
To improve the dimensional accuracy of finished products is one of the important topics in the development of rolling technology. Narrowing the size of the deviation can make the actual size of the finished product continuously close to the minimum allowable value of the corresponding standard. This will result in a significant increase in yield. The future direction of efforts is to make the dimensional accuracy of finished products exceed the standard requirements, in order to produce more excellent quality products. This method of increasing yield and improving quality also plays a particularly important role in the development of steel pipe production. Improve the dimensional accuracy of finished pipe, we must first focus on reducing wall thickness deviation.
