Melting temperature control melting temperature is too low, is not conducive to the dissolution of alloying elements and the gas discharge inclusions increase the formation of segregation, cold shut, due to the tendency of the cast, but also because of insufficient heat riser, the casting not reasonably feeding, there is data indicate that all aluminum smelting temperature should reach at least 705 degrees and should be stirred. Melting temperature is too high not only a waste of energy, the more serious because the higher the temperature of Shandong electric vehicles recovered, the more hydrogen absorption, the more coarse grains also, alumina more serious, some of the burning of alloying elements are more serious, leading to Mechanical properties of the alloy decrease, casting and machining performance deterioration, the effect of weakening the electric car Modification recovery, casting tightness is reduced. Practice has proved that the alloy was rapidly heated to a higher temperature, stirring reasonable Henan electric vehicle recovery, in order to promote the dissolution of all alloying elements (especially refractory metal element), Grilled except scum fell after pouring temperature, Thus, the minimum degree of segregation, but also less fusion of hydrogen is beneficial to obtain uniform and compact, high mechanical properties of the alloy. because the temperature of molten aluminum is difficult to judge with the naked eye, so no matter what type of melting furnace should Thermometer with temperature control. Thermometer should regularly check and repair. Thermowell should cycle with a metal brush clean, coated with a protective coating of Hunan electric vehicle recovery, in order to ensure the accuracy of the temperature measurement results and the Registrar life. A variety of aircraft aluminum alloy as the main structural material. Aircraft skin, beams, ribs, stringers, bulkheads and landing gear are made of aluminum alloy. Depending on the aircraft, the use of aluminum is not the same amount. Focus on the economic benefits of civilian aircraft due to cheaper prices and extensive use of aluminum, aluminum accounts for the body weight of the structure such as the Boeing 767 aircraft used by 81%. Military aircraft due to good operational performance requirements and a relative decrease in the amount of aluminum, such as the maximum flight speed of Mach 2.5 high-performance F-15 fighter aircraft using only 35.5% of aluminum. Some alloy has good low temperature performance, it can work in liquid hydrogen and liquid oxygen environment, it concentrated nitric acid and UDMH can not afford chemical reaction, with good welding performance, so it is a good material for the manufacture of liquid rocket. Launch of the "Apollo" spacecraft "Saturn" 5 rocket fuel tank levels, oxidant box, box between the segments, inter-stage section, tail section and the instrument module are made of aluminum alloy.
