Pickling The Forgings






Category: APPLICATION OF LIBERTY ENGINE MATERIALS TO THE AUTOMOTIVE INDUSTRY

The forgings were then pickled in a hot solution of either niter
cake or sulphuric acid and water at a temperature of 170 deg.F., and
using a solution of about 25 per cent. The solution was maintained
at a constant point by taking hydrometer readings two or three
times a day, maintaining a reading of about 1.175. Sixty forked or
one hundred single rods were placed in wooden racks and immersed
in a lead-lined vat 30 by 30 by 5 ft. long. The rack was lowered
or lifted by means of an air hoist and the rods were allowed to
stay in solution from 1/2 to 1 hr., depending on the amount of
scale. The rods were then swung and lowered in the rack into running
hot water until all trace of the acid was removed.

The rod was finally subjected to Brinell test. This shows whether
or not the rod has been heat-treated to the proper hardness. If
the rods did not read between 241 and 277, they were re-treated
until the proper hardness is obtained.
