A sliding nozzle generally consists of a drive mechanism, a mechanical component, and a refractory material section (i.e., upper and lower slides and the lower nozzle). The operating principle of a sliding nozzle is to use a sliding mechanism to slide the upper and lower slides, thereby opening and closing the steel flow hole to adjust the molten steel flow rate.

The sliding nozzle structure includes a mechanical component and a drive (manual or hydraulic). It operates in two modes:

(1) Linear reciprocating type: When the slide plate makes linear reciprocating motion, the steel flow is controlled by adjusting the steel flow hole between the sliding plate and the fixed plate.

(2) Rotary type: The sliding plate makes a rotational motion to adjust the size of the steel flow hole and control the flow rate of molten steel.

Product Features:

1. Almost all parts can be quickly replaced online.
2. A main hydraulic cylinder pulls the slide to apply pressure and automatically tighten, allowing for free travel during hot repairs.
3. Pressure is transmitted from wheel to track, resulting in low hydraulic drive force.
4. Refractory replacement is simple for workers.
5. Lightweight and easy to assemble and disassemble, minimizing maintenance workload and reducing preparation time.
6. Simple structure and low failure rate.
