Copper clad aluminum casting double metal composite core forming process of filling
By the small sample in the shear force that is completely disengaged from the sub-interface. After calculation, can withstand large shear stress, although only 1.7O ~ Ⅱ Figure 5, the shear plane in the core is aluminum, its cut surface smooth and rounded. The maximum shear stress is ∞. Driving MPa, the shear stress is greater than 60 raw aluminum. (10 Ⅶ L) a, good description of the complex in Figure 6 can withstand large shear stress although, as MPa, but it can be seen in Taiwan by the shear layer near the junction fragments. ! B. After cutting the load curve of a solemn and load-strain curve section practice lap / l direct charge of a hill after officials cut section and the load curve. Kui Qu hoard of silver carp should be a. Xiang Jin surface h_ folder cover over-charge. Curve should be children had imaginary circle 6 composite rod cladding section and the load of a shear strain after the song of a residual circle ● ● ■ A double-clad metal composite core forming process of continuous casting of charge on the different composite samples were micro-level analysis The results shown in Figure 7 to 9. No cladding of the sample (see Figure 7) connected with split samples of the table tomorrow. Combined with the thickness of the middle beyond the test requirements I5m composite thickness:. This is the copper and aluminum exposure to high temperature. And the formation of brittle compounds 【-. r Wei Jian scan pattern scan morphology and b. And l residual scan prince Yu Tong Guo Yan Jian-scan appearance and a view of Rong-shaped cover over buildings scattered blunt 【one. 9 Chicago scan the main tower-shaped cover over-saturated sample residual microscopic field scanning slit, from the inside out, line scan shows the composition of the interface of steel and aluminum have a sudden change in the larger, almost no proliferation cladding each other well sample (see Figure interface combined with compact, with rounded surfaces. Interaction between copper and aluminum have a certain spread. Diffusion of copper to the aluminum side more. Aluminum side of the weapon less spread, so frequent in this type of composite billet aluminum can see the diameter of the core NOx phenomenon of greater than ÷ 25n this phenomenon may be secluded in the atomic radius of copper is less than the radius of aluminum Snake , and aluminum liquid junction between the kidney to the smaller units,ugg prezzo, in which the diffusion of copper less reason activation energy J. : The diffusion of aluminum to the copper side of less. Easy to form a plastic - Mu better n solid solution,air jordans, conducive to the extension after the order J / l: [I. . Cladding over (see Figure 9) attempt to broadcast】 o Quarry material composite rod shear test results are also due to turn Taiwan were fractured the main reasons I trial i in the liquid aluminum in the next to go through the crucible and mold in the guide flow tube, the final temperature is determined by their being in the impact of diversion tube, put the initial temperature of molten aluminum did not affect on the test, the temperature of molten aluminum can be melted under the Mindanao interest charge (the 700 or so) for the Huan. Composite layer has a greater impact on the parameters of a copper liquid temperature and pulling speed. . Fixed emitter position under the mold 9.5mn. Different temperature and pulling speed copper liquid composite rods under the 'nitrile to inspect the status of copper liquid temperature of 250 ~】 320 ℃, the casting speed in the】 2 ~ 32mnin within the scope of qualified rehabilitation units stick out. Parameters especially in the casting speed 16w · nn, copper liquid temperature of the process parameters for the 1300 best prince Yu lo process conditions in this qualifying composite rod made of copper liquid temperature is lower than 12500C,ugg italia, the vulnerable outer surface of the bar pattern. Not on the same aluminum composite defects; and gentle solution of copper higher than 1320 ℃, the recovery units prone to defects in the casting speed over time than 12mn1in, prone to over-complex. Even layer of molten aluminum to copper, \good feasibility, can be produced through the process of good quality copper clad aluminum bimetallic composite holding. (2) test to determine the various process parameters. Water-cooled copper crucible under mold exposure and length of 20] 11m, copper liquid temperature is 1250 ~ 1320 ℃, the temperature of molten aluminum is about 700 ℃.
