The Refine And Purifying Of A356 Used For The Automobile Wheel Hub

With the development of the automotive industry in A356 aluminum alloy wheels for raw materials has been more widely used. At the same time, with the gradual lifting vehicle safety standards and wheels day fierce market competition, the mechanical properties and manufacturing costs for automotive aluminum alloy wheels also bring more and more stringent requirements. This also led to the A356 aluminum alloy increasingly stringent quality requirements.For A356 aluminum remelting, in addition to conventional ingredients, grain size and other requirements, affect the degree of purification of the alloy casting performance and yield has also been highly valued.In A356 alloy production processes, clean alloy is very critical part of the process, this paper focuses on how the refining furnace, standing, online refined settings to achieve the purification process of the alloy.For a long time on the purification of aluminum alloys lacking not only effective measures, more important is the lack of quantitative evaluation results of the purification and the industry standard. And often the lack of quantitative evaluation of some effective means of last resort would be to use some subjective experience-based, qualitative methods and indicators to measure, leading to the specific selection process is difficult to have some quantifiable indicators to evaluate the pros and cons.In this paper, the purification process of considering the choice of the furnace and online multiple choice with the process, the evaluation and test methods consider both improved, can quantify fracture traditional method, using the first of the advanced cast tensile bars and quantitative methods equivalent density, etc., but also combines quantitative results advanced laboratory as a final evaluation.Determination process selection and test methods discussed in this article, the production of key performance indicators A356 alloy has been significantly optimized by comparing the European laboratory evaluation and BMW standards, you can determine the configuration selection process and the production of alloys reached world-class standards.
