Abstract: Tilting cooling bed is essential equipment for billet continuous casting line and the hydraulic cylinder speed control and synchroni-zation control is the key to the smooth operation of the equipment. It introduces the hydraulic tilting cooling bed structure and work charac-teristic, taking a project as an example, analyzes the problems and reasons existing in cooling bed operating, puts forward using proportional valve and synchronous motor open-loop control cooling bed hydraulic cylinder as the improved scheme, hydraulic cylinders of the tilting cooling bed achieve real-time speed control and high precision synchronization effect.
