The invention provides ultra-thin glass chemical tempering equipment and a tempering method. According to the tempering equipment, the height of the bottom end of a set glass-ceramic part is lower than the height of the top end of a slot frame, in the actual production process, the bottom end of the glass-ceramic part is immersed in a molten salt solution, an ultra-thin glass part capable of beingcompletely immersed into the molten salt solution, thus complete tempering of the ultra-thin glass part is guaranteed, chemical toughening is even, and the toughening performance and yield of an ultra-thin glass product are improved; moreover, the set slot frame uses materials of stainless steel products, the surface of the slot frame is sprayed and treated with Al2O3 to prevent the slot frame from being oxidized by tempered molten salt, the quality of the molten salt solution is guaranteed, in the process of tempering, the surface of a glass is prevented from being polluted by stain ion of astainless steel support,
