3.Construction and principle

The combination of the upper and slider plate is a boundary, housing is fixed on the housing of the bottom of the ladle, support is opening part, and slider is active part.  Upper fixed plate and upper plate are fixed in the housing and slider plate and exchangeable nozzle are fixed in the slider, slider component can slide in the support component. A uniform and constant interfacial pressure is established through the spring component in the plate boundary. Under the working condition, support and housing are hinged together through the safety pin hinge. Pressure is transmitted to plate boundary through the support slide bar and the slider slide bar. Driven by the hydraulic cylinder , thereby achieving the flow control.
