挤压型材的时效处理过去一般采用间歇式炉(图37)。但是这种间歇式时效炉在查个生产线上进行完全自动化运输是困难的。因为铸锭加热、挤压、矫直、剪切、时效、氧化上色和发货等一系列的铝型材生产线中材料运输省力化是车间平面配置方面的重要问题。因此 The aging of extruded profiles used to be a batch oven (Figure 37). However, it is difficult for such batch furnaces to be fully automated for inspection on a production line. This is because the labor-saving transportation of materials in a series of aluminum extrusion lines such as ingot heating, extrusion, straightening, shearing, aging, oxidation coloring, and shipping is an important issue in the shop floor layout. therefore
