A rolling mill material handling system includes a cooling bed and an associated laying head and cooling conveyor. Hot rolled products may be cut into segments which are shifted laterally onto the cooling bed. Alternatively, the hot rolled products may be directed longitudinally in undivided lengths past the cooling bed to the laying head where ...

Roll mills are also used for warming up materials for calendering or extrusion. In such cases the warm material is cut into strips that are fed into the calender or extruder often continuously. Another application of roll mills is to cool materials discharged from an internal batch mixer in a form of large lumps (see Section 4.2.3.1.2 ).

The roll design is to take-care the load and torque required for any pass. In addition it must ensure that the physical dimensions and material of the roll are capable of withstanding the heaviest loads arising during the rolling sequence. Another important factor where roll life is concerned is the wear properties of the roll material. Roll ...
