Embodiment 1

[0022] This embodiment is the metallurgical composite process of single-layer composite titanium-aluminum bimetal strip, and the specific steps are as follows:

[0023] Put the aluminum ingot into the smelting furnace for melting, and pour the completely melted molten aluminum into the static furnace for 13 minutes, then go through the online degassing and filtration, then flow into the launder and enter the composite area. At the same time, hot air is used to continuously dehumidify the titanium strip and roll, so that the temperature of the titanium strip and roll is controlled between 150-300°C. The hot air is provided from the outside (it can be electric heating or other forms), and the air outlet is set on the movement track of the titanium strip and the roll, the purpose is to keep the titanium strip and the roll dry in the composite area, so that the surface will not form water vapor and oxidation. The titanium strip (thickness ≤ 1.5mm) is directly introduced i...

Embodiment 2

[0025] The present embodiment is the metallurgical composite process of the double-layer composite titanium-aluminum bimetal strip, and the specific steps are as follows:

[0026] Put the aluminum ingot into the natural gas smelting furnace for melting, and pour the completely melted molten aluminum into the standing furnace for 15 minutes, then go through the online degassing and filtering, then flow into the launder and enter the composite area. At the same time, hot air is used to continuously dehumidify the rolls and titanium strips, so that the temperature of the titanium strips and rolls is controlled between 150-300°C. The hot air is provided from the outside (it can be electric heating or other forms), and the air outlet is set on the continuous movement track of the roll and the titanium strip. Moisture formation and oxidation. The titanium strip has two layers (0.5-1.5mm in thickness) and is in direct contact with the molten aluminum through the guide roller...

Abstract

The invention discloses a metallurgical compound technology for a titanium aluminum bimetal compound strip. After an aluminum ingot is completely melted into molten aluminum, the molten aluminum flows into a compound region after standing by a standing furnace, online degassing and filtering, a roller and a titanium strip are continuously blown and baked by hot air in the compound region, the temperature of the roller and the titanium strip is kept at 150-300 DEG C in compounding, and the titanium strip and the molten aluminum are rolled by a rolling mill to form the metallurgical compounded titanium aluminum bimetal compound strip. The roller and the titanium strip are continuously blown and baked by the high-pressure hot air in the compound region of the titanium strip and the molten aluminum, and the temperature of the roller and the titanium strip is kept at 150-300 DEG C, so that water vapor and oxidation are avoided in compounding, water molecules are prevented from condensing on a titanium aluminum compound interface and forming bubbles, and the post processing quality of the titanium aluminum bimetal compound strip is ensured. By adding 0.2-0.5% of aluminum titanium boron wires into the molten aluminum, titanium aluminum metal molecules are metallurgically bonded. The problems of cracking, breaking, layering, falling-off and the like in post deep processing are thoroughly solved, the rate of finished products can reach more than 80%, and production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of production of titanium-aluminum bimetal composite strips, in particular to a titanium-aluminum bimetal composite [0002] Metallurgical composite process of strip. It is suitable for the metallurgical composite process of titanium and titanium alloys and aluminum or aluminum alloy bimetal strips. technical background [0003] With the rapid development of science and technology, different metal materials are combined into one through various connection methods to prepare metal composite panels, which can obtain physical, chemical and mechanical properties that single-layer metal materials do not have. Specific stiffness, fatigue resistance, dimensional stability, wear resistance, vibration resistance and other performance requirements, while saving rare and expensive materials and reducing costs. Therefore, the development of new metal composite materials has very urgent practical significance, and ...
