Glass-protective lubricant is a kind of proper material for reducing friction coefficient and isolating heat ex-change between forging and die, preventing oxidation and alloy-element leaning at the forging surface during forging and heating. Adopting composed-glass designing concept, a kind of suitable glass-protective lubricant for stainless steel forging at temperature from 850 to 1180 ℃ was acquired. By heating the composed-glass to high temperature, the changing performance of the glass-lubricant at different temperatures was studied. Based on the stainless steels heating condition in forging, the protective properities of the lubricant on the stainless steels surface was tested, and lubrica-tive mechanism for stainless steel forging of the glass-protective lubricant was analyzed.
