ABSTRACT:
A belt for use in the casting of metals and a method for its manufacture in which a metal belt is first subjected to heat treatment, quenching and tempering to improve its strength and decrease its stretchability. Then the belt is treated to introduce surface irregularities to promote uniformity of heat transfer and to allow collection of surface gases and then the belt is subjected to further thermal treatment under controlled conditions to form an oxide layer thereon to minimize adhesion between the belt and the metal deposited thereon.
