Aluminum section design should pay attention to the problem

　　1,A tolerance to develop production capacity to fully consider the vendor, because aluminum extrusion molding in the mold under hot conditions, the product of the relative tolerance of plastic parts, hardware bigger. 　　 　　2, the thickness of the material should not be too thin, on the principle of 0.8mm or more, less the amount of deformation, extrusion conditions better, there is mass productivity. 　　 　　3, hollow tube material thickness difference is not too large, generally not more than four times, otherwise difficult to trim and extrusion dies. 　　 　　4, before the official open mode, the process required to provide detailed surface effects due to surface treatment processes affect early extrusion die parting line to determine the impact extrusion die, die die size metal values （injection cause the product to change the aperture small form factor larger, lumen narrowing, and oxidation on the contrary; sandblasting can cause product aperture larger, thinner body, or cause product deformation; drawing process will have to consider leaving a margin material） 　　 　　5, extrusion material can not absolutely sharp, pointed ridge aluminum design will be around 0.3 R angle, the subsequent polishing, oxidation, fuel injection and other processes, R angle will reach about 0.4. 　　 　　6, aluminum extrusion of hollow and solid parts of the ratio should not be too poor, or too large offset, depending on the actual structure of concrete and definite.

Aluminum extrusion die performance requirements

　　A, hardness and red hardness （thermal stability）: Hardness is an important indicator of the mold. Under the mold to withstand the stress of the job role in maintaining the shape and size will not change quickly. Red means rigid mold under heat or high temperature, can stay organized and stable performance, with the ability of anti-softening. 　　 　　B, wear: mold in their work to bear considerable stress and friction, requiring mold retains its shape and size unchanged, durable. 　　C, strength and toughness: Die bear the load and shock, vibration, and other complex stress at work. Requirements of the mold should have a sufficiently high strength and a certain toughness. High strength, easy to crack the mold; strength is too low, the mold easily collapse. Therefore, the required strength and toughness have a best fit, otherwise it will cause early failure of the mold. 　　 　　D, but also consider the mold temperature strength, thermal fatigue, thermal resistance and abrasion resistance.

Explore and solve problems blast aluminous slag

　　Practice shows that the blast furnace slag Al2O3 content of more than 16% will have a greater negative impact on the stability of the furnace conditions along the line, and even cause blast disorders. For example, Wuhan No. 7 blast furnace is 3200m3 large, advanced equipment level, after the operation, achieved good operating indicators, but in June 2009, as a result of fluctuations in raw material components, sinter quality deterioration, high Al2O3 content ores, slag iron fluidity, slag and iron can not be discharged, resulting in furnace conditions along the line has become worse, causing disorders furnace conditions, to produce blast caused huge losses. To this end, Wuhan efforts to explore effective measures to solve the problem of blast furnace slag high alumina. 　　 　　According to production experience, in the Al2O3 content of more than 18 percent, rely on high MgO slag to reduce slag viscosity is not feasible, because improving the slag MgO content to rely on improving sinter dolomite flux ratio is achieved when the sinter MgO content increases, the binder phase of fluidity, as it would inevitably lead to increased fuel consumption without reducing the sinter strength. Conclusion The recent laboratory study was sinter MgO content of 2.5% is appropriate, exceed this range, sinter drum index will tend to fall. Therefore, to cope with Al2O3 content is too high due to uncontrolled sources of raw materials, need to study the suitability of the blast furnace slagging system. There are ways to reduce the viscosity of the two, one plus manganese （MnO）;. Second, plus fluorite （CaF2） due to the increase in iron ore will affect the Mn content, it should be added to the fluorite appropriate amount of research methods. 　　Wuhan Iron and Steel blast furnace No. 7 in July 2009 high Al2O3 content in slag-day average of up to 18.6%, the highest reached 22.81%, seriously affecting the separation of iron slag fluidity and iron slag, iron slag discharged directly led to difficulties. Despite many measures, such as adding manganese, hot wash furnaces and other measures, but due to the accumulation of severe hearth furnace conditions did not improve for a long time, and finally decided to wash the oven with fluorite. From July 24, 2009 to July 28, August 3 to 7, add fluorite, fluorite exhausted before using Mn ore. Additional large net during the wash-furnace coke, used to supplement the hearth heat. From the use of point of view, fluorite bonded to the furnace body scrub, treatment effect hearth piled on more significant. After joining the fluorite, significantly reducing the melting point of the slag, slag improved liquidity of iron blast furnace slag obvious, which for recovery furnace conditions played a very important role. 　　 　　It should be noted, though adding slag fluorite help to improve liquidity, but fluorite hearth furnace cooling abdominal wall with severe erosion, so the use of fluorite wash furnace to be very careful. Wuhan Iron and Steel blast furnace in dealing with the 7th July 2009 the hearth accumulation, fluorite is added to the furnace through a uniform charge, fluorite distributed throughout the material surface, a large area of fluorite and bosh, contact cooling system at the hearth, caused a lot of damage to the air, delaying the recovery time after the treatment hearth slag due to high Al2O3 caused accumulation should be improved. 　　Practice shows, CaF2 can reduce high Al2O3 slag viscosity, but CaF2 for the blast furnace refractory damage also played the role, and therefore the use of CaF2 is generally due to the high Al2O3 content in viscosity caused large hearth not live, hearth and accumulation of case use. In the case of Wuhan Iron and Steel slag Al2O3 content of less than 18% of the average daily, CaF2 content of about 2.0% on it. If the normal production time adding CaF2 use, you need to consider the capacity of the blast furnace refractories and other issues.
