In this chapter, the fundamental concepts of different types of extrusion presses and major press components are discussed. An outline of the recently integrated system, from billet furnaces and log shears to age ovens and stacking equipment to control the entire manufacturing process with high productivity, is also included. The major press and tooling components of basic types of extrusion presses for making solid sections, bars, strips, rods, tubes, and hollow sections are shown. Auxiliary and handling equipment is discussed.

This chapter focuses on the inspection of steel bars for the detection and evaluation of flaws. The principles involved also apply, for the most part, to the inspection of steel wire. The nondestructive inspection methods discussed include magnetic particle inspection, liquid penetrant inspection, ultrasonic inspection, and electromagnetic inspection. Eddy current and magnetic permeability are also covered.

This appendix contains figures that illustrate specimen orientation and crack plane codes for rolled plate, drawn bars, and hollow cylinders.
