A method for multi-layer rolling connection of composite ice skate substrate

Abstract

This invention relates to the field of rolling joining technology, and more particularly to a multi-layer rolling joining method for a composite ice skate substrate. The method includes heating the material to a target temperature using a preset heating process and maintaining the heating for a preset time; rolling the material according to a preset rolling pressure and feed rate to obtain a boundary fusion value, actual reduction rate, and echo intensity value; and determining the actual rolling pressure and actual pressure compensation value based on each fusion parameter and each preset fusion parameter threshold. This method enables the overall rolling joining state of the multi-layer material to be understood from multiple directions through the fusion state of the material's boundary after rolling, the fusion state of the middle of the multi-layer material, and the reduction rate of a single rolling pass. This information is then fed back into the dynamic adjustment of rolling parameters, achieving precise control over the joining quality of the composite ice skate substrate and enhancing the overall mechanical properties and interfacial bonding strength of the multi-layer material obtained through rolling joining.
