摘要： The spray unit lies downstream, in-line with an extrusion press and serves to cool metallic sections in particular sections of aluminum or an aluminum alloy from all sides. The cooling medium emerges from spray nozzles program-controlled in the direction of the section. The distance, the cross-section distribution and the direction of the spray nozzles are adapted specific to the geometrical shape and distribution of mass in the section. The optimum parameters are determined and stored in the unit processor. The spray nozzles are arranged in nozzle beams running in the direction of the extruded section. The nozzle beams comprise at least one longitudinal water channel and two longitudinal air channels, whereby cross-intersecting channels branch off from the water channels to the spray nozzles and the air channels terminate in air gaps which are directed towards the nozzle outlets. The extruded sections are passed through the spray unit and cooled, at a rate that exceeds the critical cooling rate specific to the material, by a program-controlled, sprayed cooling medium in a manner that takes into account the shape of the section and the distribution of mass in the section. Using uniform cooling on all sides, sections that are extruded straight can be kept straight, while sections that are distorted on extrusion can be corrected with respect to bending and/or twisting by non-uniform cooling.
摘要翻译：喷射单元位于下游，与挤压机成一直线，用于从各侧冷却铝或铝合金的特定部分的金属部分。冷却介质从沿着该部分的方向程序控制的喷嘴喷出。喷嘴的距离，横截面分布和方向适用于该部分中的几何形状和质量分布。确定最佳参数并存储在单元处理器中。喷嘴布置在沿着挤压部分的方向延伸的喷嘴梁中。喷嘴梁包括至少一个纵向水通道和两个纵向空气通道，由此交叉相交的通道从水通道分支到喷嘴，并且空气通道终止于指向喷嘴出口的空气间隙中。通过程序控制的喷射冷却介质，将挤出的部分通过喷雾单元并以超过材料特有的临界冷却速率的速度以考虑到部分的形状和分布的方式冷却的部分。使用均匀的冷却方式，直线挤压的部分可以保持直线，挤压时扭曲的部分可通过不均匀的冷却相对于弯曲和/或扭转进行修正。
