Abstract

The invention discloses a homogenizing processing method for a steel zinc 3-Graphite semi-solid composite panel, belonging to the field of research on the interface shearing strength room-temperature rolling postprocessing of the steel zinc 3-Graphite semi-solid composite panel. In the processing method, twice rolling are carried out on the steel zinc 3-Graphite semi-solid composite panel which is constituted by a 08AI steel plate with the thickness of 1.2 mm and a zinc 3-Graphite coating with the thickness of 1.5 mm by a fine rolling mill at room temperature, wherein the overall reduction ratio is 1.0%, and the ratio of the reduction ratio of the primary rolling to the reduction ratio of the secondary rolling is (1:1.5) to (3:1). By the method, the shearing strength difference of the transverse interface of the composite panel can be reduced to less than 1.7 MPa.

Description

technical field [0001] The invention relates to a method for post-processing the interfacial shear strength of a steel-zinc-graphite semi-solid composite plate after rolling at room temperature. Background technique [0002] Publication No.: CN101117696A, Invention Name: "A post-treatment method for steel-backed aluminum-based semi-solid composite board", expounds the room-temperature rolling post-treatment method for steel-backed aluminum-based semi-solid composite board, that is, at room temperature, In the precision rolling mill, the steel-backed aluminum-based semi-solid composite plate is processed after rolling, and the difference in deformation between the aluminum-based coating and the steel back produced by the rolling treatment is used to compensate for the difference between the aluminum-based coating and the steel back during the composite solidification and cooling process. The difference in the shrinkage of the steel back reduces the additional stress on the in...
