Problems solved by technology

[0003] Aiming at the disadvantages of resource allocation, high manufacturing cost, and low cost performance of the alloy plate in the prior art, the present invention provides a method of directly pressing and melting the panel and the substrate without using an adhesive. Pressurization can increase the tensile strength of the steel plate by more than 20%. On the other hand, it can reduce the difference in temperature creep between different composite materials and improve the stability of the composite.

Embodiment 1

[0023] Cold-rolled strengthened radiation-sintered clad steel sheet, such as figure 1 , 4 As shown, it includes a substrate 1 and a panel 2. The substrate 1 is a steel plate, and the panel 2 is a metal sheet or an organic sheet. The panel 2 is located on one side of the substrate 1, and the panel 2 is connected to the surface of the substrate 1 by welding. Melting pressure means that the panel 2 in contact with the substrate 1 is radiated and melted by the radiation heating device 7, and then a high-intensity pressure is applied by the main roll 4, and the pressure load is more than 2,000 tons or 1.5-5.5 times the compressive strength of the substrate 1 , so that the panel 2 is connected to the substrate 1 by high-pressure pressure-attachment in a molten state, and the mechanical bonding under high pressure and the fusion bonding under high temperature are integrated to form an alloy transition layer between the substrate 1 and the panel 2, which greatly improves the composite...

Embodiment 2

[0033] Cold-rolled strengthened radiation-sintered clad steel sheet, such as figure 2 , 4 As shown, it includes a substrate 1 and a panel 2. The substrate 1 is a steel plate, and the panel 2 is a metal sheet or an organic sheet.

[0034] The roughness of the bonding surface of the substrate 1 and the panel 2 is 200 μm. The joint surface of substrate 1 and panel 2 is a clean surface, which needs to be derusted, dewatered, degreased, and ash-removed.

[0035] The anchor grain direction of the roughness of the panel 2 is consistent with the anchor grain direction of the roughness of the substrate 1 . The roughness can be shot blasting, and high-strength steel wire roller can be used for high-speed padding, which has directionality. In this plan, fine shot blasting is used first, and then the steel wire wheel is used to scratch the anchor pattern to form a metallurgical bond. Panel 2 is an aluminum plate.

Embodiment 3

[0042] Cold-rolled strengthened radiation-sintered clad steel sheet, such as image 3 , 4 As shown, it includes a substrate 1 and a panel 2. The substrate 1 is a steel plate, and the panel 2 is a metal sheet or an organic sheet. The panel 2 is located on one side of the substrate 1, and the panel 2 is connected to the surface of the substrate 1 by welding. A hard plastic or soft metal liner 3 is arranged between the base plate 1 and the panel 2, and the soft metal liner 3 is soft metal such as zinc plate or copper plate, which is applicable when the surface of the base plate 1 is uneven.

[0043] The roughness of the bonding surface of the substrate 1 and the panel 2 is 300 μm. The joint surface of substrate 1 and panel 2 is a clean surface, which needs to be derusted, dewatered, degreased, and ash-removed.

[0044] The anchor grain direction of the roughness of the panel 2 is consistent with the anchor grain direction of the roughness of the substrate 1 . The roughness can b...

The composite steel plate comprises a baseplate (1) and one or more panels (2), wherein the baseplate (1) is a steel plate; the one or more panels (2) are made of metal sheet materials or organic sheet materials and positioned on one side or two sides of the baseplate (1) and connected onto the surface of the baseplate (1) through melt pressure. The manufacturing equipment comprises a main roller (4) and a radiation heating device (7), wherein the radiation heating device is arranged between the main roller (4) and the baseplate (1). The cold-rolled reinforced radiation clinkering composite steel plate and the manufacturing equipment have the advantages that through the integration of reinforcement and compound function, the mechanical bond and the melting bond are integrated, high infrared instantaneous heating fusing is conducted, meanwhile, the selective heating with the a compound area is achieved, and the energy loss is less.

Description

technical field [0001] The invention relates to special steel and its manufacturing equipment, in particular to a cold-rolled strengthened radiation-sintered composite steel plate and its manufacturing equipment. Background technique [0002] At present, as a basic material of structure and construction, steel plate needs to have different functions on its surface and interior in order to realize the optimal allocation of resources. Although alloy plates can achieve similar functions, there is a waste of resource allocation. The steel plate surface layer is combined with thinner materials for anti-corrosion, decoration and other corresponding functions, which can effectively improve the cost performance. Contents of the invention [0003] Aiming at the disadvantages of resource allocation, high manufacturing cost, and low cost performance of the alloy plate in the prior art, the present invention provides a method of directly pressing and melting the panel and the substra...
