6063铝棒质量提高的措施探讨 In order to reduce the harmful effect of iron, the following measures can be taken. A) smelting, casting and applying all the tools before using the paint to minimize the iron soluble aluminum liquid. B) refine the grain, make the iron thinner, smaller, and reduce its harmful effects. C) add the right amount of strontium to make beta phase alpha and reduce its harmful effects. D) careful selection of waste materials, reducing iron wire, nails, iron filings and other debris as much as possible to make iron content increase. Other impurities Other impurities are small in electrolytic aluminum ingots, well below national standards, and may exceed the standard when recycling waste and aluminum. In production, not only should control each element cant exceed bid, and to control the total quantity of the impurity elements also cannot exceed bid, when a single element content is not to exceed bid, but total exceeds bid, the impurity elements also has a great influence on the profile quality. Special need to emphasize that the proposed practice proves that the zinc content to 0.05 (national standard of not more than 0.1) profile after oxidation surface appears white spots, so to control the zinc content below 0.05. Tri.6063 aluminum alloy smelting Control the melting temperature Production of high quality casting of aluminium alloy smelting is bar one of the most important process, improper process control, will produce in casting with slag, porosity, coarse grains, feathers and other casting defects, crystal must therefore be kept under strict control. 6063 aluminum alloy melting temperature control between 750-760 ℃ is beautiful, too low will increase the production of slag, high increase hydrogen, oxygen, nitrogen absorption loss. Research shows that the solubility of hydrogen in aluminum liquid in sharp rise above 760 ℃, when heat by means of reducing hydrogen absorption and many, such as drying smelting furnace and smelting tool, to prevent the use flu
