Embodiment Construction

[0008] A uniform post-treatment method for steel-aluminum solid-liquid phase clad plates, at room temperature, on a precision rolling mill, for steel-aluminum solid-liquid phase cladding consisting of 1.2mm thick 08Al steel plates and 1.0mm thick industrial pure aluminum cladding For the plate, carry out post-rolling treatment with a total reduction rate of 3.5% in two passes, and decompose and coordinate the large difference in the lateral deformation of the aluminum cladding caused by the post-rolling treatment with a large reduction rate in a single pass into two passes The small difference in the lateral deformation of the aluminum cladding produced by the post-rolling treatment at the second minimum reduction ratio further reduces the difference in the transverse interface shear strength of the clad plate and improves the distribution of the shear strength of the steel-aluminum solid-liquid phase clad plate interface Uniformity.

Abstract

The invention discloses a uniform post-processing method for a steel-aluminum solid-liquid composite plate, which belongs to the field of room temperature rolling post-processing study on the interfacial shear strengths of a steel-aluminum solid-liquid composite plate. The method is implemented through the step of carrying out two-pass rolling processing on a steel-aluminum solid-liquid compsite plate on a precise rolling mill at room temperature so as to reduce the difference between the transverse interfacial shear strengths of the composite plate to below 3MPa, wherein the steel-aluminum solid-liquid composite plate is composed of a 08Al steel plate with the thickness of 1.2mm and an industrial pure aluminum coating with the thickness of 1.0mm, the total relative draught of the two-pass rolling is 3.5 percent, and the ratio of the first-pass reduction rate to the second-pass reduction rate is (1:6) to (1:2).

Description

technical field [0001] The invention relates to a post-treatment method of rolling at room temperature for the interfacial shear strength of a steel-aluminum solid-liquid phase composite plate. 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 steel b...
