Abstract：
 This invention relates to a new Ni base high temperature alloyed material used in rolls and its hot process technology, which takes K403 alloy as the base and adjusts composition of the alloy to eliminate Co element and adds W, Nb and Fe suitably to melt it in vacuum, then carries out different hot processes to get the nickel base alloy, which replaces traditional roll materials and has the performance of anti-high temperature and oxidation, anti-hot impact and high temperature intensity to prolong its life time.
