Understanding Rolling Process in Long Product Rolling Mill ...

Tension control. In a continuous mill, speed matching the stand to achieve a constant mass flow through the mill assures a low cobble rate and fewer defects. High tension can stretch reduce the cross section of the bar making shape control very difficult. At the extreme, tension can pull the bar apart, creating a cobble.
