During the processing of aluminum alloy die castings, a large crystal structure is effectively formed. In comparison with forgings and rolled materials, it requires a prolonged solid solution treatment and aging process for optimal performance. The melting temperature during the melting process is close to the melting point of low-melting-point eutectic crystals. Therefore, it requires a heating furnace with temperature control capability and standard instruments for temperature manipulation.
Different alloys in aluminum casting have different strengthening phases due to variations in chemical composition. Casting coke is specifically used in conjunction with iron-smelting furnaces for melting iron. Casting coke is a crucial source of energy for melting iron in the furnace. Its role is to melt the charge and superheat the molten iron, while maintaining good permeability of the coke bed.
Therefore, casting coke should possess characteristics such as high net weight, low reactivity, low porosity, sufficient impact resistance and crushing hardness, and poor ash and sulfur content. Casting is the process of melting the metal, manufacturing the mold, and pouring the molten metal into the mold to obtain a solidified metal component with the desired shape, dimensions, and characteristics.
Aluminum alloy die castings are effectively obtained by melting the metal into a desired solution and pouring it into the mold. During the subsequent cooling and solidification process, as well as post-treatment processing, the desired shape, dimensions, and characteristics of the casting are achieved. Due to the near-net shape of the casting, it reduces the need for extensive machining or requires minimal additional processing. This reduces costs and, to some extent, reduces the processing time.
Aluminum alloy die castings have unparalleled advantages compared to other types of castings during processing. They are known for their appealing appearance, lightweight, and corrosion resistance, making them highly favored by users. Especially with the trend of automotive lightweighting, aluminum alloy die castings have been widely applied in the automotive industry.
