To reduce the impact of biofouling, antifouling coatings have been developed and applied to marine vessels since ancient times. Traditional antifouling coatings consist of chemically active compounds, such as silver, copper and tributyltin (TBT) .These coatings lack specificity, exhibit high toxicity to both fouling organisms and nontarget marine life, and lead to contamination of …

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 ).

Roll changes on such mills are relatively frequent and time consuming. This type of mill is therefore used for primary rolling where rapid change of shape is required, even at the expense of surface quality. Four-high mills are a special case of two-high, and in an attempt to lower the rolling load, the work roll diameter is decreased.

The roll zone is the area over which the rolls act on the material, it is here that plastic deformation of the work occurs. An important factor in metal rolling is that due to the conservation of the volume of the material with the reduction in thickness, the metal exiting the roll zone will be moving faster than the metal entering the roll zone.
