Abstract
IT is not a little surprising that an important industrial process, well over a hundred years old, should have had to wait until now for an author. Particularly is this the case where the process is one which has shown such marked advances as has extrusion during the past twenty or thirty years. Starting as a means of forming lead pipes, it is now a method of working metals which is of first-rate importance, and its potentialities, so far from being exhausted, may result in its serious incursion in the comparatively near future from the realm of non-ferrous metallurgy into that of the steels.
