Abstract

The invention discloses a uniform aftertreatment method of a steel and zinc 3 graphite solid-liquid phase composite plate, belonging to the field of research on room-temperature rolling aftertreatment of the interfacial shear strength of the steel and zinc 3 graphite solid-liquid phase composite plate. The invention is characterized in that two-pass rolling treatment with total reduction ratio of 2.3% and proportion of first pass reduction ratio and second pass reduction ratio of 1:2 to 2:1 is carried out on the steel and zinc 3 graphite solid-liquid phase composite plate formed by a 1.2mm-thick 08Al steel plate and a 3.0mm-thick zinc 3 graphite coating on a precise rolling mill at room temperature. The method can reduce the difference of the horizontal interfacial shear strength of the composite plate within 1.8MPa.

Description

technical field [0001] The invention relates to a method for post-processing the interface shear strength of a steel-zinc-graphite solid-liquid phase composite plate after rolling at room temperature. Background technique [0002] Publication No.: CN1710114A, Invention Name: "A post-treatment method for steel-backed aluminum-based solid-liquid phase composite plate", described the room temperature rolling post-treatment method for steel-backed aluminum-based solid-liquid phase composite plate, that is, at room temperature Next, in the precision rolling mill, the steel-backed aluminum-based solid-liquid phase composite plate is subjected to post-rolling treatment, and the difference in deformation between the aluminum-based cladding and the steel back produced by the rolling treatment is used to compensate for the deformation of the aluminum-based composite plate during the composite solidification and cooling process. The difference in shrinkage between the cladding and the ...
