最近几年铝挤压加工主要是用挤压机来完成,但是设置在挤压工序前的铸锭加热装置对产品质量,生产率都有很大影响。铸锭加热装置有感应加热和火焰加热两种。多数采用感应加热。现在几乎所有的工厂都是由挤压机操纵者兼管加热装置的操作。电子电气加热所固有的良好控制性能,因此它能充分地满足用户的需要。随着技术不断发展,国外挤压车间逐渐地实现无人化,但是在自动化方面还存在问题。下面就感应加热控制方法加以介绍:
In recent years, aluminum extrusion processing is mainly done by an extruder, but the ingot heating device provided before the extrusion process has a great impact on product quality and productivity. Ingot heating device induction heating and flame heating two. The majority of induction heating. Almost all of the plants are now operated by extruder operators. Electrical and electronic heating inherent good control performance, so it can fully meet the needs of users. As technology continues to evolve, the extrusion plant in foreign countries gradually becomes unmanned, but there are still problems in automation. The following induction heating control method to be introduced:
