Compound strip material with high bonding strength and making method thereof

Abstract

The invention discloses a compound strip material with high bonding strength and a making method thereof, and relates to the technical field of metal plate strip making. The making method of the compound strip material comprises the steps of machining a plurality of grooves in the surface of a metal strip I, pouring molten liquid of a metal strip II on the surface of the metal strip I under the protection of a vacuum environment or inert gas, and conducting continuous cast-rolling at the same time. The compound strip material is high in bonding strength and unlikely to shed, the mode of pouring the molten metal liquid and conducting synchronous cast-rolling is adopted, that is to say, root taking between metal layers which are mutually combined is achieved, the process is simple, the production efficiency is high, the compound strength is high, the energy consumption is low, and the product quality is very stable.

Description

technical field [0001] The invention relates to the technical field of manufacturing metal strips, in particular to a composite strip with high bonding strength and a manufacturing method thereof. Background technique [0002] At present, the production of many composite metal strips only stays at the solid-solid composite level, mainly through rolling and crimping, cladding welding, blasting composite, and composite ingot hot rolling. The current production method has disadvantages such as complex production process, high production cost, low efficiency, low composite strength, and unstable product quality, especially the low composite strength, which is basically a common shortcoming of most composite materials. [0003] In the prior art, there is a method of solid-semi-solid compounding, pouring molten low-melting point metal on another metal plate, and then sending it to a rolling mill for rolling after the two are combined and semi-solidified. This method is waiting for...

The current production method has disadvantages such as complex production process, high production cost, low efficiency, low composite strength, and unstable product quality, especially the low composite strength, which is basically a common shortcoming of most composite materials.

[0003] In the prior art, there is a method of solid-semi-solid compounding, pouring molten low-melting point metal on another metal plate, and then sending it to a rolling mill for rolling after the two are combined and semi-solidified. This method is waiting for solidification The process takes a long time to reduce production efficiency. Second, in order to prevent oxidation, the entire process needs to be carried out in a vacuum environment or under the protection of an inert gas, which consumes a lot of energy. In addition, the bonding strength of this bonding method is still not high enough, and there are still situations where it is easy to peel off
