1070 aluminum alloy explosion-proof foil and processing technology thereof

Abstract

The present invention discloses a 1070 aluminum alloy explosion-proof foil and a processing technology thereof. The explosion-proof foil contains rhenium, iron, rare earth metals and aluminum. The processing technology includes preparing raw materials according to ratios, preparing the alloy, smelting, smelting in a holding furnace, grain refinement, online degassing and deslagging, filteration deslagging, continuous casting and rolling, cold rolling, finish rolling, cutting and packing. Due to the configuration of the material composition, deoxidation, desulfurization, dehydrogenation, denitrification and grain refinement abilities of the aluminum melt in the smelting process are improved, and the explosion-proof foil has characteristics of good corrosion resistance, high strength at a room temperature and a high temperature, good wear resistance, etc. By employing processing methods such as smelting, continuous casting and rolling, cold rolling, foil rolling, small feeding amount and multi-pass horizontal rolling, and natural aging, the strength and flexibility of the aluminum alloy foil are improved, with a short entire process and a low production cost. The aluminum foil mesh formed by slitting and expanding the explosion-proof foil has the advantages of good toughness, and being not easy to crack and shedding metal debris, so that the safety performance requirements of the aluminum alloy explosion-proof aluminum foil used in aerospace oil tank and fuel tank are satisfied in use.

Description

technical field [0001] The invention relates to a processing technology of an aluminum alloy material and an aluminum alloy plate, in particular to a 1070 aluminum alloy explosion-proof foil and a processing technology thereof. Background technique [0002] Metal materials are used to replace organic antistatic agents in tank trucks and oil storage tanks. The main purpose is to effectively slow down the sloshing of oil products in the oil tank, reduce the frictional resistance between oil products and the inner wall of the oil tank and the inner wall of the transportation pipeline, and prevent frictional static electricity. Fire and decomposition combustion explosion impact. [0003] The key technology for the production of aluminum alloy foil for explosion-proof foil mesh is that it has good corrosion resistance. The aluminum alloy foil mesh after slit and expansion has good toughness, and is not easy to break and fall off metal debris. In the prior art, there are two kind...

Problems solved by technology

The above-mentioned alloy ratio is complicated, the production process is high, the cost is high, the explosion-proof foil has insufficient toughness, and the corrosion resistance and wear resistance are poor. The immersion of tank oil and the phenomenon that metal debris is easy to fall off under bumpy transportation have caused serious safety hazards to oil transportation.
