Converter slag retaining mechanism consists of a base, a support, a fixed part, a sliding frame, a spring component, etc. The upper slide gate plate brick is fixed in the base frame, and the lower slide gate plate brick and the lower nozzle brick are fixed in the sliding frame. The sliding frame can be reciprocated in the support through the slideway, and the moving interface establishes constant and uniform interface pressure through the spring assembly. The hydraulic cylinder of the power source drives the sliding frame to reciprocate through the driving component to realize the flow control and slag retaining of the molten steel.
The sliding nozzle control mechanism is composed of a base, a support, a slide block, a spring box, a pressing elbow, the upper nozzle brick, the upper slide gate plate brick, the lower nozzle brick and the lower slide gate plate brick. The pressing and loosening of the upper slide gate plate brick and the lower slide gate plate brick are controlled by the spring box mechanism. Because the layout of the spring box is reasonable, it is less affected by high temperature, the elasticity is long, not easy to loose, easy to use, simple structure, small size, light weight, long service life and so on.
