rolled thread. (b) Grain flow in machined and rolled threads. Unlike machining, which cuts through the grains of the metal, the rolling of threads causes improved strength, because of cold working and favorable grain flow. Figure 13.15 Thread-rolling processes: (a) and (c) reciprocating flat dies; (b) two-roller dies.

Heavy-duty bending rolls used for rolling shell plates etc. to the correct curvature are hydraulically operated. Two lower rolls are provided and are made to revolve in the same direction so that the plate is fed between them and a slightly larger diameter top roll that runs idly (see Figure 13.3).Either or both ends of the top roll may be adjusted for height, and the two lower …

3.1. Rolling Force Model. The moving steel plate can be considered as a mass flow that is conveyed along the cooling roller table from the entry (roughing rolling) to the exit (finishing rolling). Over this period of time, the steel plate exchanges energy with the environment by convection and radiation.

Roller dams are a type of weir, or a dam that is designed to allow water to flow over the top in continuous action. They are used on rivers or other such moving bodies of water where erosion damage is undesirable, yet likely to occur. A short wall, lip, or parabolic channel is constructed on the downstream side of the dam parallel to the dam face.
