During the normal operation of the ingot casting and tilting process, faults in the aluminum holding furnace's automatic tipping system are common. However, after each casting cycle, a loud impact noise is produced when the furnace body is tilted back. Upon investigation, it was discovered that this noise is caused by the spools of pipe rupture valves 2 and 13 being suddenly closed and then reopened during the tilting motion. After repeated impacts, the valve spools become damaged, the retaining nuts loosen and detach, and the spools remain inside the valve body while the nuts move freely within the piping.
In subsequent casting cycles, several issues arise. The fixing nut becomes stuck at the valve core of electromagnetic reversing valve 8, causing the high-pressure gear pump to return oil directly to the tank through the valve, resulting in insufficient pressure and preventing the furnace from tilting. During the casting process, the damaged valve core blocks the oil flow at the pipe joint of the valve body, which stops the furnace from continuing to tilt upward, ultimately leading to casting failure. In some cases, if either pipe rupture valve 12 or 13 is damaged, the two valves momentarily close during the return tilting. The undamaged valve core is opened by the throttle valve 7, allowing the back pressure to be re-established. However, the damaged valve core cannot open due to the absence of spring force, blocking the oil return path and preventing the furnace from returning to its original position. As a result, the entire tilting mechanism fails.
From these failures, it is clear that the main cause is the damage to pipe rupture valves 12 and 13, which is primarily due to the mechanical stress caused by the sudden return movement. This repeated impact leads to progressive wear and eventual failure of the valve components. To prevent such issues, regular maintenance and inspection of the valve systems should be carried out, and any signs of wear or damage should be addressed immediately to avoid further complications and downtime in the production process.
An electric actuator is a device that converts electrical energy into mechanical motion. It is used to control the movement of various mechanical systems, such as valves, dampers, and other industrial equipment. Electric actuators are commonly used in industrial applications where precise positioning, speed control, and high accuracy are required. They are also used in the automotive industry, aerospace industry, and medical equipment. Electric actuators are available in different types, including linear actuators, rotary actuators, and multi-axis actuators. They can be powered by AC or DC power sources and can be controlled by various types of controllers, such as programmable logic controllers (PLCs) and human-machine interfaces (HMIs).
