The application results proved that the hot coil box technique can reduce the thickness tolerance of the ends of strips and improve the quality of products in hot strip rolling production.
实践证明：在带钢热连轧生产中采用热卷箱技术可以减小成品带钢的头尾厚度公差，提高产品质量。

The thermal nonreciprocity in sensing coil is one of sources induced temperature drift in FOG , so the fiber loop is usually wound by quadrupole(QAD) symmetrical technique.
A new forming process for tapered suspension coil spring of Audi passenger car is introduced, and the technique and key points the design of the new process are also analysed.
