Alcoa公司的5588毫米厚板轧机设计说明书介绍了一些较困难的设计问题。最后确定的设计说明书要求所设计的热轧铝材作业线用铝锭生产铝材,铝合金板和板坯。供给轧机的铝锭厚304.8～660.4毫米,宽762～1828.2毫米,长3.9～5.4米,重2727～18128公斤。轧出的铝板最小厚度为9.525毫米,最大板宽为5334毫米。 Alcoa公司要求所设计的轧机具有9072吨的轧制压力,以便能轧制现有的几种铝合金,但为了能适应未来可能的发展,即轧制更多品种铝材,也要求轧机具有附加的能力。大部分产品所需的轧制压力在9072吨范围内,少量产品所需的轧制压力为15876吨。第一步是确定适于承受这些负荷的轴颈尺寸,按所承受的负荷得出轴颈的直径为1498.6毫米。
Alcoa’s 5588 mm plank mill design sheets present some of the more difficult design issues. The finalized design specification requires that the hot-rolled aluminum line be designed to produce aluminum, aluminum alloy plates and slabs from aluminum ingots. Aluminum ingots supplied to the mill are 304.8 to 660.4 mm in thickness, 762 to 1828.2 mm in width, 3.9 to 5.4 m in length and 2727 to 18,128 kg in weight. The minimum thickness of rolled aluminum is 9.525 mm and the maximum width is 5334 mm. Alcoa required that the mill be designed to have a rolling pressure of 9,072 tons in order to be able to roll several of the existing aluminum alloys but in order to be able to adapt to the possible future development of more varieties of aluminum, Ability. The rolling pressure required for most products is in the range of 9,072 tons and the rolling pressure required for a small number of products is 15,876 tons. The first step is to determine the size of the journal suitable for these loads. The diameter of the journal is 1498.6 millimeters at the load.
