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 aluminum alloy materials and aluminum alloy plates, in particular to a 1070 aluminum alloy explosion-proof foil and its processing technology. Background technique [0002] Use metal materials to fill tank trucks and oil storage tanks instead of organic antistatic agents. Its main purpose is to effectively slow down the sloshing of oil in the tank, reduce the frictional resistance between the oil and the inner wall of the tank and the inner wall of the transportation pipeline, and prevent friction and static electricity. Fire and decompose combustion explosion impact force. [0003] The key technology for the production of aluminum alloy foil for explosion-proof foil mesh is that it has good corrosion resistance. The cut and expanded aluminum alloy foil mesh has good toughness and is not easy to crack and fall off metal chips. In the prior art, the metal materials used in tank trucks and oil storage tanks a...
