Aluminum die casting and metal particles in the hard inclusion


Combined oxides, the formation of nodules in the furnace wall. Nodulation on the furnace wall material used for x-ray structure analysis confirmed which contains a considerable amount of aluminum silicate (Al203 · Si02), see Figure 7.4 preventive measures to prevent hard spots and non-metallic clip, he should take the following measures . (1) charge should be no oil dust, stored in a dry place to prevent rain and moisture in the surface charge produces a thick corrosion layer of gas and alumina as well as the inclusion of people with liquid aluminum. (2) small pieces of aluminum material surface area, with more than one oxide inclusions, can not be directly added as a charge. (3) transfer of liquid aluminum flow injection should pay attention to the smooth flow and prevent the splash of liquid aluminum, and should minimize the number of bits transferred. (4) selection of high-o3 content refractory lining materials, fire-resistant lining to prevent the molten aluminum and ask a lot of reaction, slag, and furnace wall cleaning residue on time. (5) rotating the rotor method (RID),uggs online bestellen, or injection blow nitrogen flux method (Wu) and other efficient methods of refining refining of molten aluminum. The measures on the elimination of hard spots in die casting and non-metallic inclusions have a good effect. To an aluminum alloy die casting,mulberry vesker, for example, in more than six months,mulberry norge, has completely eliminated the casting of the hard particles. Greatly reduces machining scrap.
