一、前言关于铝,特别是变形合金熔炼、铸造中的熔体处理,7年前本刊已登载过,因此,熔体质量管理的重要性,在当时就已有很高的认识。这个背景是由于电子仪器、飞机等尖端技术领域的铝材适用范围在扩大,并随着从量到质的转变,制品开始向高质量化方面发展。以锭坯为出发点,将典型铝制品板厚、壁厚和制品单位重量的关系示于图1。现在使用的主要制品、若以锭坯厚度为基准,则板厚减少到1/10~3~1/10~5,制品单位重量减少到
First, the preamble About aluminum, especially in the deformation alloy melting, casting melt processing, 7 years ago, this article has been published, therefore, the importance of melt quality management, already had a high level of understanding. This background is due to the expansion of the scope of application of aluminum in cutting-edge technologies such as electronic equipment and aircraft. With the shift from quantity to quality, products have started to develop in higher quality. Billet as a starting point, the typical thickness of aluminum products, wall thickness and product weight relationship shown in Figure 1. If the main product currently used is based on the thickness of the billet, the thickness of the billet is reduced to 1/10 to 3 to 1/10 to 5, and the unit weight of the product is reduced to
