Abstract

The invention discloses a homogeneous post-processing method of steel red copper solid-liquid phase composite plate, belonging to the post-processing research field of the interface shear strength and the rolling at room temperature of the steel red copper solid-liquid phase composite plate. The method comprises the step of carrying out a two-pass rolling processing on the steel red copper solid-liquid phase composite plate by a precision rolling machine at the room temperature to reduce the transverse interface shear strength difference of the composite plate to less than 3 MPa, wherein the steel red copper solid-liquid phase composite plate is composed of a 08 A1 steel plate with a thickness of 1.2 mm, and a red copper coating layer with a thickness of 3.0 mm; the total reduction is 2.8%, and the pass reduction proportion of the first pass and the second pass is 1:5-1:3.

Description

technical field [0001] The invention relates to a method for post-processing the interface shear strength of a steel red copper 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 ste...
