摘要/Abstract

摘要： 以海外新建汽车铝合金轮毂厂的天然气热处理炉为例,考虑炉温均匀性的影响,对铝合金轮毂进行热处理工艺验证。炉温均匀性优化前后,分别测试了铝合金轮毂的力学性能和显微组织。结果表明,接近烧嘴的A层轮毂断后伸长率较低,显微组织出现Al-Si共晶颗粒粗化现象;底部的C层轮毂,与最上的A层和中间的B层相比较,力学性能最差,Al-Si共晶组织球化不足。炉温均匀性优化后,通过力学性能和显微组织检验,各层样品未出现明显差异,符合产品技术要求。

Abstract: For the natural gas heat treatment furnace of the newly built automobile aluminum wheel hub plant overseas, considering the influence of furnace temperature uniformity, the process verification of heat treatment of aluminum alloy wheel hub was carried out. Before and after the optimization of the furnace temperature uniformity, the mechanical properties and microstructure of the aluminum alloy wheel hub were tested respectively. The results show that the elongation after fracture of the wheel hub on A layer closing to the nozzle is relatively lower, and coarsening of Al-Si eutectic particles appears in the microstructure. The wheel hub on the bottom layer C, compared with that on the top A layer and the B layer in the middle, has the worst mechanical properties and insufficient spheroidization of the Al-Si eutectic. After optimizing the temperature uniformity of the furnace, there is no obvious difference in the specimens on each layer according to the mechanical properties and microstructure test, which can meet the technical requirements of the product.
