Embodiment 1

[0011] A method for manufacturing aluminum and titanium composite metal strips, comprising the following steps: heating and smelting metal aluminum, refining and degassing at 810°C, and after refining and degassing, when the temperature of the aluminum liquid is 690°C, the molten aluminum is Stand still for 5 minutes, then pour into the preheated nozzle of the aluminum casting and rolling machine, the cast aluminum liquid is cooled and crystallized into a semi-solid state; choose a titanium strip with a thickness of 0.1mm, and the titanium strip is firstly treated with alkali washing and degreasing , and then put the titanium strip close to the surface of the grinding roller for single-sided online grinding until there is no oxide layer on the surface. After grinding, the titanium strip is heated online to 170°C; the semi-solid aluminum and the titanium strip are combined The grinding surface is contacted, and anaerobic continuous casting and rolling is carried out. The rolling...

Embodiment 2

[0013] A method for manufacturing aluminum and titanium composite metal strips, comprising the following steps: heating and melting aluminum alloy liquid according to the chemical composition of aluminum alloy grade 1050, refining and degassing at 790°C, and after refining and degassing, when the aluminum liquid is When the temperature is 760°C, let the molten aluminum stand for 15 minutes, and then pour it into the preheated nozzle of the aluminum casting and rolling machine. The cast aluminum liquid is cooled and crystallized into a semi-solid state; Strips, two titanium strips are treated with alkali washing and degreasing, and then the two titanium strips are respectively attached to the roller surface of the upper and lower grinding rollers for single-sided online grinding until there is no oxide layer. After grinding, the titanium The strip is heated online to 180°C; semi-solid aluminum is brought into contact with the polished surfaces of two titanium strips for anaerobi...

Abstract

The present invention discloses a method for producing aluminum-titanium compounded metal plate strip by continuously casting semi-solid aluminum or aluminum alloy and solid titanium plate strip in absence of oxygen. In the method, an oxygen-free metallurgical compounding is realized for solid titanium plate strip and aluminum liquid, so the problem of aluminum oxidization is solved, additionally, the compounding strength is high and the bonding strength is more than 100MPa, production efficiency is increased by tens of times, and product quality is stable, the produced aluminum-titanium compounded metal plate strip holds original surface quality of titanium plate and has uniform thickness of titanium layer and can be further processed through cold rolling, and various titanium plate strips different in components and aluminum liquid can be used; the invention can provide various products with wide application and has advantages of advanced process, few production procedures, energy saving, material saving and remarkable economy benefits.

Description

technical field [0001] The invention relates to the technical field of manufacturing metal strips, in particular to a method for manufacturing aluminum and titanium composite metal strips. Background technique [0002] Titanium and aluminum are important non-ferrous metals, which are widely used in industrial and civil fields. Titanium has good electrical and thermal conductivity, corrosion resistance, and antibacterial properties, and aluminum has good electrical and thermal conductivity. Compared with aluminum, titanium resources are in short supply, while aluminum resources are abundant, the proportion of aluminum is small, and the price is low. Aluminum and titanium composite metal strip is a kind of bimetal with aluminum as the matrix and outer layer coated with titanium. It combines the high-quality electrical conductivity and low-cost resources of aluminum with the high chemical stability and low contact It is a new type of conductor material and decoration material ...
