Problems solved by technology

[0006] To sum up, it can be seen that in the current prior art, the aluminum-clad strip usually uses a binder to realize the physical compounding of steel and aluminum, and there is a problem of poor bonding strength of steel and aluminum.
Moreover, since the substrates used in the prior art have extremely high requirements for P content, the production of aluminum-clad strips in the prior art is extremely difficult

Embodiment 1-15

[0055] Examples 1-15 The aluminum substrate includes a steel substrate and an aluminum layer covering the surface of the steel substrate, wherein the coated aluminum strip of Example 1-8 employs 0.2 mm aluminum strip as an aluminum layer in a steel substrate. On (see figure 1 ) image 3 ), The mass percent of each of the chemical elements of the steel substrates, as shown in Table 1.

[0056] Table 1 lists the mass percentage (wt%) of each of the chemical elements in the steel substrate of the aluminum substrate in Examples 1-15.

[0057] Table 1. (wt%, margin is Fe and other inevitable impurity elements other than s)

[0058]

[0059] The method for producing an aluminum plate strip of Examples 1-15 is made of the following steps:

[0060] (1) The steel strip is obtained according to the steel substrate component listed in Table 1 and 0.2 mm aluminum layer as an aluminum strip.

[0061] (2) Surface treatment of the steel strip and aluminum belt.

[0062] (3) Aluminum is covered ...

Abstract

The invention discloses an aluminum-clad strip, which comprises a steel substrate and an aluminum layer coated on the surface of the steel substrate; the mass percentage ratio of chemical elements of the steel substrate is: 0<C≤0.02%, 0<Si≤0.005 %, Mn: 0.05‑0.5%, P: 0.018‑0.03%, Al≤0.005%, N: 0.0040‑0.010%, Ti: 0.01‑0.04%, O: 0.02‑0.050%, the balance being Fe and other unavoidable of impurities. In addition, the present invention also discloses a method for manufacturing the above-mentioned aluminum-clad strip, which includes the steps of: (1) preparing the steel strip and the aluminum strip; (2) performing surface treatment on the steel strip and the aluminum strip; (3) The aluminum strip is covered on the surface of the steel strip for room temperature rolling; (4) annealing; (5) finishing and straightening. The aluminum-clad plate strip has good mechanical properties, and the steel-aluminum interface bonding performance is excellent.

Description

Technical field [0001] The present invention relates to a slate and a method of manufacturing the same, and more particularly to a coated aluminum tape and a method of manufacturing the same. Background technique [0002] With the development of technology and economy, the performance requirements of metal materials are increasing, and single composition metal materials are often difficult to simultaneously meet multi-faceted performance during actual use. Two or more metal materials are selected by a variety of different processes to form a composite sheet to meet special comprehensive performance requirements. The aluminum steel is a composite sheet belt covering the aluminum film on the surface of the steel surface under room temperature conditions to form the surface of the steel surface, the core layer is a composite sheet belt, which has both steel strength, and has good heat dissipation, corrosion resistance. , Lightweight and beautiful characteristics, especially signific...
