Embodiment Construction

[0051] In the 60KA electrolytic cell, add iron-removing silicon-titanium alumina powder (containing a small amount of boron oxide and rare earth oxide). Aluminum alloys containing low titanium, boron, rare earth and silicon are produced directly by electrolysis in cryolite system electrolyte. Adjust the chemical composition in the aluminum mixing furnace. The chemical composition of the electrolytic ZL101 aluminum-silicon alloy is as follows (mass fraction, %): Si7.24, Mg0.36, Fe0.11, Ti0.11, B0.0001, RE0.036. The average grain size of the α primary dendritic aluminum phase is 350 μm (Fig. 1). The average grain size of ZL101 alloy (titanium content is 0.10-0.15%) treated with Al-Ti master alloy under the same process conditions is 700 microns.

Abstract

The invention relates to a refined crystal grain aluminum alloy and the manufacturing method. It is made up from Si 0.2-7.5wt%, Mn 0.05-1.5wt%, Mg 0,05-6.0wt%, Zn 0.03-8.5wt%, Cu 0.05-7.0wt%, Ni 0.1-2.5wt%, Ti 0.01-0.15wt%, RE 0.01-0.3wt%, B 0.0001-0.10wt%, and the rest is Al. The technology feature is that it adds silicon titanium alumina, borax and or rare earth oxide or rare earth carbonate, or titanium oxide, borax and/or rare earth oxide or rare earth carbonate into aluminum cell. Add the manganese oxide, compound of copper or Ni would be also added. Comparing to traditional technology, the refiner is not added, and the refining effect is enhanced and the perdurability is prolonged. It could be used to produce wire, band, tube, panel, aluminum foil, etc.

Description

technical field [0001] The present invention relates to a kind of aluminum alloy of fine grain and preparation method thereof, more precisely add silicon titanium aluminum oxide or titanium oxide and borax and / or rare earth oxide or rare earth carbonate (when needed Manganese oxide, copper compounds or nickel compounds can also be added), and these compounds are directly electrolyzed to obtain fine-grained aluminum alloys containing refined elements titanium, boron and / or rare earths, and then other chemical components are adjusted in the aluminum mixing furnace . The present invention does not use master alloy type refiners. Background technique [0002] Fine-grained aluminum alloy has good plasticity and punchability, and is an ideal material for the production of wire, strip, pipe, plate, aluminum foil, engine cooling fins, beverage cans, and auto parts. [0003] At present, there are three types of methods for refining aluminum or aluminum alloy grains: [0004] 1. Ch...
