A tandem rolling mill is a rolling mill with two or more close-coupled stands, each of which is setup for rolling using the spring curve and the compressive curve of the metal so that both the rolling force and the exit thickness of each stand are determined.. The main advantages of a tandem mill are: only one single pass is required which saves time and increases production; …

A steam engine is a heat engine that performs mechanical work using steam as its working fluid.The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work.The term "steam engine" is generally applied only to reciprocating …
