Embodiment

[0018] Melting: Use 97.195Kg of A00 aluminum ingots with an aluminum content of 99.7% and put them into a melting furnace for heating and melting. When the temperature reaches 680°C, the aluminum is completely melted into a liquid, stop the fire to remove the slag, degas the impurities in the aluminum liquid, after cleaning, add Mn 1.25Kg, Zn 0.1Kg, Fe 0.7Kg, Mg 0.03Kg, Cu 0.125 Kg, Si0.6Kg, continue to heat and melt, when the temperature reaches 725°C and completely melt, stop the fire, flow into the static furnace, and remove impurities. The molten aluminum was left to stand still for 35 minutes in a static furnace.

[0019] Casting and rolling billet: aluminum water passes through the crystallizer and tractor, and after being pulled by the tractor, the drawn head is rolled into the coiler, and the drawn billet is rolled up to make 4 tons / coil with a thickness of 6.7mm thick rolls.

[0020] Cold rolling mill rolling: The cold rolling mill rolls the billet, the rolling pass...

Abstract

The invention discloses an obstruction and explosion suppression material aluminum foil of an oil tank for a gas station. The aluminum foil comprises the following components in percentage by weight: 0.4 to 0.8 percent of Si, 0.5 to 0.9 percent of Fe, 0.05 to 0.2 percent of Cu, 1.0 to 1.5 percent of Mn, 0.05 to 0.15 percent of Zn, 0.02 to 0.04 percent of Mg and the balance of Al. The aluminum foil has relatively high flexibility and tensile strength; the obstruction and explosion suppression material, which is used for preparing the aluminum foil, of the oil tank for the gas station has relatively appropriate softness and hardness; and residues and powder are prevented from falling and an oiling machine is prevented from being blocked when the aluminum foil is used.

Description

technical field [0001] The invention relates to an anti-explosion material, in particular to an aluminum foil of an oil tank barrier anti-explosion material in a gas station. Background technique [0002] The traditional production of aluminum foil is annealed once during the production process. In addition, the intermediate foil blanks between 0.3 and 0.45mm are hot-rolled finished products without annealing, that is, the H18 state, and the tensile strength is actually 250Rn / cNmm 2 In the above hard state, after the aluminum foil is punched into a net, it becomes brittle and foams off. [0003] The other is no intermediate annealing and finished annealing. That is the H26 status. Because there is no annealing in the middle. From the 7.0mm billet has been rolled to a foil thickness of 0.05mm. Rolled to 0.25 ~ 0.3mm. The annealing temperature is 300°C and the time is 16-20 hours. After changing the internal crystallization of aluminum, aluminum rolling is carried out. ...
