Tension Control Bolts, Grade S10T, in Friction Grip ...

Tension control bolts (TCBs), are a type of high-grade bolt that can be preloaded by a tightening process that is carried out entirely at the threaded end (i.e. at the nut or spline end) of the bolt. Consequently, TCB's are usually distinguished by their round heads (rather than hexagonal heads) and splines.

Looper and tension control in hot rolling mills: A survey ...

Looper and tension control, shown in Fig. 2, is important in hot strip mills because they affect both the dimensional quality and the mass flow of a strip. The high strip tension between stands induces width shrinkage, thickness reduction and moreover can produce an edge wave on a strip. However, it does make the mass flow more stable and hence ...

Understanding Rolling Process in Long Product ... - IspatGuru

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.

Practice Guide of Web Tension Measurement and Control

measured values are proportional to web tension if the systems are correctly dimensioned. Because of possible non symmetrical load distri-bution over the rolls it is customary to measure the forces in both bearings of the idler roll. The core of the web tension sensors are strain gauge transduc-ers measuring the acting forces.
