Description

Technical Field

[0001] The present invention belongs to the technical field of aluminum composite plates, and in particular relates to a rolling preparation method for a high-strength metal wire reinforced aluminum-based composite plate. Background Art

[0002] In recent years, layered composite plates have developed rapidly in the armor field. Aluminum composite plates are a new type of aluminum material made by combining multiple materials. Compared with aluminum / aluminum composite materials, aluminum / wire / aluminum composite materials can significantly improve the material's resistance to impact damage and enhance the material's protection level. Most aluminum / wire / aluminum composite materials currently on the market are produced using vacuum hot pressing and sintering. Although its preparation process is becoming increasingly mature, its preparation process still has disadvantages such as complex process, difficult processing, and high fuel consumption. In addition, due to the limitations of vacuum heating furnaces, it is impossible to produce large-scale plate / wire / plate composite materials, and continuous production is difficult to achieve in engineering. Compared with vacuum hot pressing, the rolling process has high production efficiency and can be automated and mass-produced.

[0003] Patent No. CN202011615188.2 discloses a metal plate of copper-aluminum composite high-strength steel wire and a preparation method thereof, which discloses a method for laying the steel wire: cooling the aluminum alloy to a semi-molten state, and then feeding the copper plate, steel wire, and semi-molten aluminum alloy into the rolling mill for oxygen-free continuous casting and rolling, wherein the side of the copper plate without an oxide layer faces the semi-molten aluminum alloy; by controlling the feeding angle of the steel wire, the position of the steel wire in the semi-molten aluminum alloy can be controlled. The steel wire can be embedded in the surface of the semi-molten aluminum alloy at the beginning and then further pressed into the semi-molten aluminum alloy by the copper plate, so that the semi-molten aluminum alloy wraps the steel wire, or it can be directly inserted into the semi-molten aluminum alloy, and then the semi-molten aluminum alloy is further rolled with the copper plate. During the preparation of the metal sheet, the steel wire is fed into the aluminum alloy cooled to a semi-molten state by controlling a certain angle to achieve the purpose of laying the steel wire in the aluminum plate; however, the laying method of the steel wire has many control details during the operation and is difficult to operate.

[0004] The hot rolling process is relative to the cold rolling process. The cold rolling process is carried out below the crystallization temperature, while the hot rolling process is carried out above the crystallization temperature. Compared with the cold rolling process, the hot rolling process has the following technical points: 1) Hot rolling can significantly reduce energy consumption and reduce costs. During hot rolling, the metal has high plasticity and low deformation resistance, which greatly reduces the energy consumption of metal deformation. 2) Hot rolling can improve the processing performance of metals and alloys, that is, it can crush the coarse grains in the casting state, significantly heal cracks, reduce or eliminate casting defects, transform the cast structure into a deformed structure, and improve the processing performance of the alloy. 3) Hot rolling usually uses large ingots and large reduction rolling, which not only improves production efficiency, but also creates conditions for increasing the rolling speed and realizing the continuity and automation of the rolling process.

[0005] However, in the existing rolling process of aluminum plate / wire / aluminum plate, the steel wire and the plate cannot be well coordinated in deformation, and problems such as the interface cannot be tightly bonded easily occur, resulting in the inability to well improve the impact resistance of the composite plate. Summary of the Invention

[0006] The present invention aims to address, at least to some extent, one of the technical problems in the related art. To this end, the present invention primarily aims to provide a method for rolling and preparing high-strength metal wire-reinforced aluminum-based composite plates. This method aims to address the problems of existing preparation methods, such as the complexity of the process, the difficulty of processing, the inability to produce large sizes, and the inability to achieve large-scale, continuous production.

[0007] The purpose of the present invention is achieved through the following technical solutions:

[0008] A rolling preparation method for a high-strength metal wire reinforced aluminum-based composite plate comprises the following steps:

[0009] S1) pre-treating the aluminum plate and the steel wire with pre-made riveted through holes;

[0010] S2) distributing the steel wires in each hole of the inner mold in sequence, and then compacting and fixing them with the outer mold;

[0011] S3) placing the pretreated lower aluminum plate on a flat workbench, laying the fixed steel wire on the pretreated lower aluminum plate, and then covering the upper aluminum plate on the steel wire to form an aluminum plate / wire / aluminum plate;

[0015] S7) The insulated stacked plates are fed into a rolling mill and hot rolled with a large reduction to ensure a strong bond between the upper and lower aluminum plates and the steel wire, thereby obtaining a hot-rolled metal plate.

[0016] The present invention uses aluminum plates and steel wires as raw materials, and uniformly arranges steel wires of specific diameters in the holes of the inner mold in sequence, and uses an outer mold to compact and fix the laid steel wires. During use, the diameter and distribution spacing of the steel wires can be adjusted by changing the hole spacing of the inner mold; then, by placing a lower aluminum plate under the steel wire and an upper aluminum plate above the steel wire, stacking them into a "sandwich" structure, and riveting them with pure aluminum rivets; remove the outer mold and the inner mold, place the stacked plates in a muffle furnace for insulation, and then send them into a rolling mill for large-scale reduction to obtain a hot-rolled metal plate. The hot-rolled metal plate is placed in a muffle furnace at the solid solution temperature for an appropriate period of time, taken out, and water-cooled. The solid solution metal plate is placed in an oil bath furnace at 120°C for an appropriate period of time to prepare a T6 metal plate with uniform distribution of steel wires.

[0017] In some specific embodiments, the pretreatment is specifically: cleaning and degreasing the aluminum plate with prefabricated riveted through holes, and polishing the upper and lower composite surfaces of the aluminum plate with a wire brush until a fresh surface is exposed; cleaning and degreasing the steel wire.

[0018] In some specific embodiments, the aluminum plate is in an annealed state and has a thickness of 3-5 mm; the steel wire is made of 304 steel and has a diameter ranging from 0.02 to 1 mm.

[0019] Furthermore, the aluminum alloy is 7A52 or 7A01 aluminum alloy, and the length, width and thickness are 80mm×60mm×4mm respectively.

[0020] In some specific embodiments, the mold includes an outer mold and an inner mold arranged in parallel, and the inner mold is arranged on the inner side of the outer mold.

[0021] Furthermore, the distance between two adjacent through holes of the inner mold and the diameter of the through holes can be adjusted;

[0022] Furthermore, the outer mold includes two groups of left and right pressing molds, each group of pressing molds includes a first upper mold and a first lower mold, and both ends of the first upper mold and the first lower mold are provided with countersunk holes, and threaded connectors are provided on the countersunk holes.

[0023] Furthermore, the inner mold includes two groups of left and right fixed molds, each group of fixed molds includes a second upper mold and a second lower mold, and both ends of the second upper mold and the second lower mold are provided with countersunk holes, and threaded connectors are provided on the countersunk holes; at the same time, the pressing contact surfaces of the second upper mold and the second lower mold are uniformly arrayed as paving holes.

[0024] The threaded connector is interference fit with the inner mold and the outer mold;

[0025] In some specific embodiments, the process parameters of the insulation in step S6) are: insulation temperature of 350-460°C, insulation time of 25-40 minutes, and heating rate of 9-11°C / min.

[0029] Compared with the prior art, the present invention has at least the following advantages:

[0030] 1) This invention solves the problem of inconsistent deformation between the steel wire and the composite plate by aligning the length of the steel wire during laying, aligning the steel wire's width with the rolling direction. A method for uniform wire laying is also designed to address the problem of thin steel wires being prone to spontaneous deflection and tangling due to their softness and flexibility, resulting in tangles and clumping during laying and preventing evenly spaced laydowns.

[0031] 2) The present invention utilizes a die to lay out the wires, stack them, and preheat them before rolling the steel wires directly into a 1XXX series aluminum alloy. This method utilizes a hot rolling process to produce a composite aluminum plate / wire / aluminum plate. This method is simple to operate and easy to control. By varying the die's hole spacing, the diameter and spacing of the steel wires are regulated. Through subsequent work hardening and heat treatment, the aluminum plate / wire / aluminum plate interface is tightly bonded and free of significant defects, enhancing the impact resistance of the aluminum plate / wire / aluminum plate metal sheet. Compared to conventional vacuum hot pressing and sintering methods, this method offers advantages such as energy savings, simplified processing, ease of fabrication for large-scale plate sizes, and engineering feasibility.

[0087] Performance Testing

[0088] This application takes Example 2 as an example to perform microscopic morphology characterization and Charpy impact mechanical property testing on the prepared high-strength metal wire reinforced aluminum-based composite plate.

[0089] 1) Interface morphology

[0090] This application uses TESCAN MIRA3 electron microscope equipment to scan the bonding interface of the metal plates. The results are as follows: Figure 3 and Figure 4As shown in the figure, it can be seen that the spacing between the steel wires is uniform and there is basically no void at the interface between the steel wires and the plate, indicating that the steel wires are evenly distributed in the composite plate and the bonding between the steel wires and the plate is good.

[0091] 2) Impact resistance test

[0092] This application uses the ZBC-300 fully automatic pendulum impact testing machine to perform impact load-displacement and impact toughness tests on metal plates. The results are as follows Figure 5 and Figure 6 As shown in the figure, when hot-rolled, the maximum force with steel wire added to the composite plate increased by 27.2%, while the displacement values ​​remained essentially the same, and the impact toughness increased by 20.9%. When in the T6 state, the maximum force with steel wire added to the composite plate increased by 21.3%, and the impact toughness increased by 15.7%. Compared to the hot-rolled state, the maximum force with steel wire added to the composite plate increased by 25.0%, and the impact toughness increased by 22.5%. This indicates that, under the same heat treatment process, the 7A52 / wire / 7A01 composite plate with steel wire added can significantly improve the impact resistance of the composite plate; the composite plate in the T6 state also has significantly improved impact resistance compared to the hot-rolled composite plate.
