Embodiment Construction

[0008] A uniform post-treatment method for steel BFe30 nickel-nickel solid-liquid phase composite plate, at room temperature, on a precision rolling mill, for the steel BFe30 nickel-nickel solid-liquid phase composed of 1.2mm thick 08A1 steel plate and 1.5mm thick BFe30 nickel-nickel coating Composite plate, carry out the post-rolling treatment of the second pass and the total reduction rate of 2.6%, and decompose and coordinate the large difference in the lateral deformation of the BFe30 nickel-nickel cladding caused by the single-pass high-reduction rate rolling post-treatment into The small difference in the lateral deformation of the BFe30 cupronickel cladding after the second-pass small reduction rate rolling treatment further reduces the difference in the transverse interface shear strength of the clad plate and improves the interface shear of the steel BFe30 cupronickel solid-liquid phase clad plate. Uniform distribution of shear strength.

Abstract

The invention discloses a method for uniformly post processing a steel BFe30 cupronickel solid and liquid phase compound plate and belongs to the research field of rolling post processing for the interface shear strength under room-temperature of the steel BFe30 cupronickel solid and liquid phase compound plate. In the method, the two-pass rolling treatment having a press reduction ratio of first pass to second pass being 1:4.5 to 1:2.5 and a whole press reduction rate of 2.6% is performed on the BFe30 cupronickel solid and liquid phase compound plate formed by a 1.2mm thick 08Al steel plate and a 1.5mm thick BFe30 cupronickel covering layer at room temperature on a precise rolling machine, so as to decrease the shear strength difference of the crosswise interface of the compound plate to the scope within 2.9MPa.

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 BFe30 nickel-nickel 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 ...
