Refractory materials are primarily used in high-temperature industries such as steel, building materials, non-ferrous metals, and military applications. A sliding gate mechanism is a device used to control the flow of molten steel during steelmaking. Currently, there are numerous sliding gate mechanism suppliers, with Hebei Ruihua Metallurgy being a prominent example. A sliding gate generally consists of a drive unit, a mechanical component, and a refractory component (i.e., upper and lower slides and a lower gate). The sliding gate operates by sliding the upper and lower slides, thereby opening and closing the steel flow hole to adjust the molten steel flow rate. The sliding gate system has rapidly developed due to its excellent controllability and its ability to improve steelmaking efficiency.

The ladle sliding gate mechanism is installed at the bottom of the ladle. Molten steel, exceeding 1,000 degrees Celsius, passes through it before entering the tundish or vibrator. The sliding gate can be opened and closed at will, controlling the steel temperature and regulating the steel flow, while protecting the equipment and operators below the ladle. Sliding gate systems are now widely used in ladles and tundishes both domestically and internationally.

Our main products include converter slide slag retaining mechanisms, ladle sliding nozzle mechanisms, tundish quick-change mechanisms, tundish stopper opening and closing mechanisms, hydraulic equipment, refractory materials, drainage sand, and other services. We also provide contracting services for hot and cold repair sections and converter slag retaining systems.

Features of Ruihua Metallurgical’s ladle sliding nozzle products:

1. Almost all parts can be quickly replaced online.
2. A master 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.
