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
The present invention relates to a kind of rolling post-treating method of interface shear strength room temperature of steel BFe30 copper-nickel alloy solid-liquid-phase composite plate.
Background technology
Publication number: CN1710114A, denomination of invention: on " a kind of post-treating method of steel-back aluminium-base solid-liquid-phase composite plate ", set forth the rolling post-treating method of room temperature of steel-back aluminium-base solid-liquid-phase composite plate; Promptly; At room temperature, on finishing rolling mill, to steel-back aluminium-base solid-liquid-phase composite plate; Be rolled aftertreatment; Utilize the difference of aluminium base coating that rolling processing produces and steel backing deflection to remedy the difference of aluminium base coating and steel backing shrinkage in the composite solidification process of cooling, and then reduce composition board interface additional stress, the composition board interface shear strength is improved.This method technology is simple, composition board interface shear strength value improves bigger; But; Because this method is carrying out there is aluminium base coating deflection non-uniform phenomenon when one-pass roller is handled; Therefore cause the uneven distribution of composition board interface shear strength usually, can be in composition board interface shear strength difference transversely up to 3～5MPa.
Steel BFe30 copper-nickel alloy solid-liquid-phase composite plate is the solid-liquid-phase composite plate that is made up of thick 08A1 steel plate of 1.2mm and the thick BFe30 copper-nickel alloy coating of 1.5mm; When adopting the CN1710114A patented process to be rolled aftertreatment; At ideal draft comparatively is under 2.6% condition; Because BFe30 copper-nickel alloy coating is at composition board deflection skewness transversely, cause the difference between the composition board interface shear strength transversely can be up to 5.6MPa.
For steel BFe30 copper-nickel alloy solid-liquid-phase composite plate, the difference of transverse interface shearing resistance is more little, and work reliability is high more, and range of application is wide more, so the difference of steel BFe30 copper-nickel alloy solid-liquid-phase composite plate transverse interface shearing resistance is more little good more.
Summary of the invention
Technical problem to be solved by this invention is; Overcome the deficiency of the existing rolling post-treating method of steel BFe30 copper-nickel alloy solid-liquid-phase composite plate room temperature " transverse interface shearing resistance difference is big "; A kind of post-treating method that can improve steel BFe30 copper-nickel alloy solid-liquid-phase composite plate transverse interface shearing resistance distributing homogeneity is provided, further dwindles the difference of composition board transverse interface shearing resistance.
The technical solution adopted for the present invention to solve the technical problems is: to steel BFe30 copper-nickel alloy solid-liquid-phase composite plate; At room temperature; On finishing rolling mill, carry out total draft and be percentage pass reduction ratio 2.6%, first passage and second passage and be 1: 4.5～1: 2.5 the rolling processing of two passages.
The invention has the beneficial effects as follows: for the rolling processing of composition board room temperature; Because roller is jumped, the existence of the unequal factor of matrix; Transversely produce nonaffine deformation inevitably in composition board, cause the difference of composition board transverse interface shearing resistance, and draft is big more; Distortion transversely is inhomogeneous more, and the difference of composition board transverse interface shearing resistance is big more.If nonaffine deformation transversely with the rolling generation of single pass heavy reduction rate; Decompose in the middle of the little draft distortion of multi-pass; Then can one-pass roller be handled the big-difference of the transverse deformation amount that produces; Be decomposed into the little difference of the transverse deformation amount of multi-pass, and pass through the optimum combination of each percentage pass reduction, can also further coordinate the difference of transverse deformation amount.The present invention utilizes the optimum combination of the percentage pass reduction of first passage and second passage further to reduce and coordinated the difference of the transverse deformation amount of the rolling processing of room temperature, thereby has reached the purpose that reduces composition board transverse interface shearing resistance difference.Utilize the present invention; Steel BFe30 copper-nickel alloy solid-liquid-phase composite plate is carried out the rolling processing of room temperature; Can composition board transverse interface shearing resistance difference be reduced in the 2.9MPa, reduce by 48% at least than adopting the CN1710114A patented process to carry out the 5.6MPa that the rolling processing of room temperature obtains.
