铝在国民经济各部门中的应用使其产品品种日益扩大和对它的质量要求不断提高.比如,在许多工业部门中广泛应用宽度为2000毫米以上的壁板,这些壁板是先由水压机压成带筋的直径为600毫米以上的管材,然后展平为板.它们有各种壁厚,同时带有内或外的加强筋.使用这种产品可以大大地提高金属的利用系数,减少生产工时.所以满足国民经济对这种产品的需要是当前最迫切的任务.
The application of aluminum in various branches of the national economy has led to the widening of its product variety and its ever-increasing demand for quality, for example, in many industrial sectors, panels with a width of more than 2000 mm are first pressed by hydraulic presses Ribbed pipe with a diameter of 600 mm or more, then flattened to a plate, with various wall thicknesses, with internal or external stiffeners, which can greatly increase the utilization factor of the metal and reduce the production Working hours, therefore, to meet the needs of the national economy for such products is the most urgent task at present.
