  • Rolling oil compositions and method of inhibiting carbon smut on batch annealed steel
    Patent number: 4346014
    Abstract: Carbon smut on post-annealed cold rolled steel sheet and strip is inhibited by a process using a rolling oil containing from 0.5 to 5% by weight of specific organic nitro compounds in the cold rolling oil. The steel sheet and strip are substantially smut free after batch annealing. Rolling oils and their aqueous emulsions containing the organic nitro inhibitors are also disclosed and claimed.

  • Method of improving surface characteristic of heat-treated metal
    Patent number: 4214924
    Abstract: The invention provides a method for reducing the incidence of thermal decomposition products of metal-treating compositions on the surface of metal heat-treated in the presence of such compositions. The compositions are modified with certain acetylenic alcohols to improve their clean-burning characteristics; the resulting decrease in residual decomposition product on the metal surface facilitates subsequent processing.
