Definitions

  • EXAMPLE 2 A similar experiment was conducted on the casting of 6 tons of stainless steel. In the case where the sleeve contained 18% aluminum by weight, excessive heat was generated resulting in burning of the sleeve. The maximum reduction of the aluminum content which was possible was noted when the content was reduced to 9%. When the aluminum content was reduced to this level, the volume of the aluminum required for obtaining the same effect as that obtained from the sleeve of the prior art was noted to be almost one third of the volume of aluminum required for such sleeve of the prior art, and the cost was reduced by approximately 53%.
