Seamless Pipes Manufacturing

Unlike the plug mill, the mandrel mill reduces wall thickness continuously with a series of pairs of curved rollers set at 90 angles to each other. After reheating, the pipe is passed through a multi -stand stretch-reducing mill to reduce the diameter to the finished diameter.

Dynamic analysis of vibration stability in tandem cold

2019/10/1Mill chatter can be reduced by reducing the reduction ratio, increasing the back tension, or decreasing the friction coefficient in a specified range without decreasing the rolling speed. (2) Considering the effect of dynamic roll gap variation, and time-varying coupling between the rolling conditions and negative damping, an innovation and validated stability criterion is proposed.

Effect of minimum friction coefficient on vibration stability

The control of the work roll roughness had a positive effect on reducing the mill vibrations. The main reason was that the non-dimensional actual oil film thickness was smaller when the work roughness was larger, and thus, the friction coefficient was reduced and the stability region was enlarged ( ∂ μ M i x e d ∂ H c 0 ), as shown in Eq.

3B(2) Deformation of Rolling Mill

The mill modulus is 500-1,000 ton/mm for plate rolling mills and 400-600 ton/mm for cold rolling mills. The larger the diameter of the back-up rolls, the higher the mill modulus. A rolling force of the order of 1,000 tons is generated during rolling, so that mill deformation of more than 1mm occurs.
