Cross roller speed and pressure of the relationship is more complicated.
1) roller speed increases, the increased number of rolling molten material per unit of time, cause horizontal pressure increases;
2) roller speed increase melt increase frictional heating, caused by rising temperatures melt viscosity decreases, the transverse pressure decreases;
3) roller speed increases, the pressure increased so that the horizontal stress and increase.
Therefore, the speed and its relationship to the separation roller is the combined result of several aspects. The measured, with the increase of roller speed, horizontal pressure increases more slowly.
