This illustration shows the continuous carburizing furnaces used for case-hardening
such parts as transmission gears, rear axle ring gears, etc. The work is
pushed through one of these furnaces at regular intervals and requires 12 hours
for the complete "cooking" process. After parts are removed, they are quenched
in oil or other solutions to harden them.
Heat-treating Packard parts is an exact science. Temperatures are used in the
Packard plant from 30? F. to 2800? F. and methods of measuring and accurately
checking these temperatures are most modern.
Heat-treating Packard parts should be interesting to your prospect. The linen
collar you have on would not look or wear so well if it were not first starched
and then heat-treated with modern machinery. Neither would our mother's pies be
so digestible if the dough in the crust were not heat-treated.
Given the same ingredients, three cooks make three different kinds of pies -
depending upon their experience, judgment and knowledge of the art of cooking.
Apply this same truth to steel, and here again, Packard having originated much
heat-treating machinery and many heat-treating processes does the job better.
Again, this is another pocketbook reason for your prospect.
