Abstract

The invention discloses an aluminum-zinc-silicon-strontium-rare earth alloy ingot for continuous hot dipping and a manufacturing method of the aluminum-zinc-silicon-strontium-rare earth alloy ingot and relates to the technical field of alloy materials. The aluminum-zinc-silicon-strontium-rare earth alloy ingot is prepared from the following components in percentage by weight: 55 percent of aluminum, 43.19 percent of zinc, 1.65 percent of silicon, 0.1 percent of strontium and 0.06 percent of rare earth. The prepared aluminum-zinc-silicon-strontium-rare earth alloy coating has the characteristics of good adhesion performance, reliability in durability, oxidative resistance and acid and alkaline resistance and is capable of prolonging the service life of a coating product, solving the problem in the prior art of eliminating impurities which are generated as a melt of an aluminum alloy with a high ratio flows and an alloy melt is in a state of a high-temperature zinc pot for a long time and enabling the application of the product to be stable.

Description

Technical field: [0001] The invention relates to the technical field of alloy materials, in particular to an aluminum-zinc-silicon-strontium rare earth alloy ingot for continuous hot dip coating and a manufacturing method thereof. Background technique: [0002] Hot-dip galvanizing is the most common and effective anti-corrosion treatment method, which is widely used in the environment. At present, it has been widely used in the anti-corrosion treatment of steel structures such as electric power, communication, national defense, transportation and industrial and civil buildings. The main method is Including improved Sendzimir method, Sharon method and subsequent improved method, Galavalume and Calfan method. [0003] The improved Sendzimir method is a process method for continuous hot-dip galvanizing. It connects the independent oxidation furnace and reduction furnace in the Sendzimir method by a passage with a smaller cross-sectional area, which includes preheating furnace, ...
