Anti-corrosive sheet ingot

Abstract

The invention discloses an anti-corrosive sheet ingot and belongs to the field of chemical components of sheet ingots. The anti-corrosive sheet ingot contains the following components in percentage by mass: 0.6%-1.0% of silicon, 0.35%-0.45% of iron, 0.03%-0.08% of copper, 1.4%-1.8% of manganese, 1.3%-1.7% of zinc, 0.05%-0.2% of zirconium and the balance of aluminum and inevitable impurities. The potential of the sheet ingot is improved by adding zinc; a main channel through which a heat exchange fluid penetrates is protected by the anti-corrosive sheet ingot serving as anode protection through preferential corrosion of a sacrificial anode; meanwhile, the content ratio of manganese is improved; the strength performance is obviously improved; and the problem that a preferentially corroded fin can cause insufficient support force for a fin channel of a cooler core body is avoided, so that the corrosion resistance of the anti-corrosive sheet ingot is improved; meanwhile, the strength of the anti-corrosive sheet ingot is relatively high; the quality of a cooler prepared from the anti-corrosive sheet ingot is improved; the service life is prolonged; and wide application is facilitated.

Description

technical field [0001] The invention relates to a plate ingot, in particular to a corrosion-resistant plate ingot. Background technique [0002] The cooler is one of the heat exchangers, which is also called a heat exchanger, that is, a device capable of exchanging heat. It is a kind of heat transfer between materials between two or more fluids at different temperatures. The energy-saving equipment for transfer can transfer heat from a higher fluid to a lower temperature fluid, so that the fluid temperature can reach the index specified in the process to meet the needs of process conditions, and it is also one of the main equipment to improve energy utilization. [0003] Coolers are widely used in various industries, and many of them work in working environments or where the heat exchange fluid is highly corrosive. However, the fins of coolers in this environment are extremely easy to corrode. Therefore, it is not easy to develop a Corroded cooler fins are fundamental to ex...
