Continuous casting machines in the steel industry operate under extreme conditions, where precise control of hydraulic and pneumatic systems is critical to maintaining production efficiency and quality. The pressure switch plays a vital role in monitoring and regulating the hydraulic circuits that drive the mold oscillation units, ensuring consistent flow and pressure to prevent defects in the steel ingot formation. By detecting deviations in system pressure, it triggers automatic adjustments or shutdowns to protect expensive machinery and prevent costly downtime. This function is essential during the high-speed casting process, where even minor fluctuations can lead to surface imperfections or structural weaknesses in the final product. In secondary applications, it supports auxiliary systems such as cooling water circulation and lubrication units, maintaining operational stability across the entire production line. Its integration into these critical systems ensures reliable performance in the demanding environment of modern steel manufacturing.
