UBC aluminum material recovery process
Some molten aluminum to prepare for the next furnace operation. 4 to discuss the previous presentation and discussion of three UBC aluminum material recovery process, they have their own characteristics. Now, these three processes briefly to do some comparison. Look at re-gasification process, which is the treatment of waste materials of aluminum complex of old technology. UBC in the recovery of aluminum alloy material, since the furnace is re-joined the briquette UBC, UBC must remove all paint surface is very slow, so the recovery furnace production efficiency is not high, because of UBC Ballast is in addition to paint and melting about 810 In addition, the complex of the alloys after melting pot, but also to re-re-melting of the ingots so that the whole recovery process of the melting energy consumption increases, the economy is not enough. Look again at double-hearth furnace melting process, it is also a mixed waste treatment process of aluminum material. UBC aluminum material side in the recovery (continued on page 25) for a 21 �� �� �� r dispersion strengthened Another important use of platinum and rhodium is used for extracting the glass fiber and glass wool and rock wool, for glass fiber reinforced plastic ( GFK) and electric, acoustic and thermal insulation (glass fiber and mineral fiber), for example, dispersion strengthening of PtRhl0 for basin-shaped spinning nozzle, the diameter of the bottom l to 2ram of thousands of discharge hole, you can pull from these holes infinite length of glass or blown by hot air or superheated steam short stack fibers (stapelfaser). By-bit extension, La-use 5 to 25m in diameter and fine fibers here, in the spinning nozzle is heated by direct current to the llO0 ~ C and 1j50 ��, or between the glass melting, or the flow of melt temperature insulation , PtRh excellent high temperature performance materials are fully utilized, its life of up to several months, sometimes up to several years for the PtAu Taijin, the ODS strengthened (FKs16PtAu5) to optimize the performance of this alloy. PtAu characteristics of the alloy is. The gold, so the glass melt infiltration decreases. On PtAu5, the glass provide lubrication resistance than the pure platinum of about 3 times larger, and thus guarantee. Is the glass melt in the crucible by the PtAu out without leaving residues,[link widoczny dla zalogowanych], which makes this Taijin attack by a glass melt processing, mineral salt, the melting crucible,[link widoczny dla zalogowanych], molding equipment and utensils as well as an ideal experimental material. Especially for going to do x-ray inspection of metal containers used in the sample, which is ideal Taijin. Persistent strength of traditional materials in high temperature low, and long life of this material. In addition to Semiconductor, the glass area of industrial and laboratory applications, the dispersion strengthened platinum application in other areas is also increasing. Such as a car engine spark plugs, after processing of very small platinum rod as the electrode, platinum spark plugs, this is not easy to smoke, which the city traffic and short distance transport to reduce pollution is very favorable. Platinum material in aerospace applications are interesting aspects of materials made of platinum wire or molded parts of the catalytic decomposition of different fuels so that the special anti-i in the drive mechanism, are dispersion strengthened platinum material used to conduct a feasibility This material is also used to test the rocket and satellite control nozzles. The use of temperatures above 1600 ��. Xin-Li Li Quoted S. 492 ~ 498 (continued from page 21) surface. Although it is shorter than the recovery of the process and energy, but add dual-chamber furnace with preheating forklift room is UBC bulk. In the warm room on the bath surface. The UBC was a certain thickness of bulk material layers. Furnace gas in the 540c, UBC is the bulk of the addition to paint from top to bottom, while the molten metal bath from the contact with the bottom surface of the material layer starting up for, so the top surface of the metal material layer and high temperature furnace gas in contact for a long time. Oxidation loss is higher. In addition, the material layer in addition to paint and melting heat transfer process is relatively slow, therefore, its production efficiency is not high. In the preparation of alloys, due to no forced circulation bath. Taijin the composition of molten aluminum is not easy to control. Finally, in addition to paint a look at the melting process. Although it is more than the previous one except the two craft paint system,[link widoczny dla zalogowanych], but in terms of recycling materials UPC aluminum Taijin,[link widoczny dla zalogowanych], it is very necessary. In addition to painting torn to pieces before the first UBC, which makes paint debris in addition to the complete minutes of the kiln in addition to paint, and almost no oxidation, paint the metal burning was only 0.5, after which the net {b hot fragments, and in addition to paint directly from the melting furnace hearth room fell on the small pool of molten aluminum, and then pressed into the molten aluminum melt mixer,[link widoczny dla zalogowanych], and the electromagnetic pump forced circulation, so the process of production efficiency, low energy consumption, minimal oxidation loss products, easy to control the alloy composition. To sum up. UBC aluminum material in these three recovery process, I think the melting process in addition to paint a more advanced and reliable. 25 ---
