Snref Ls50 Ladle Upper Slide Gate Plate with Nozzle for Steel Molten Melt Flow Control
Product Description
Slide gate plate brick is becoming more and more important in modern iron and steel smelting process, and becoming an indispensable part of smelting.
It is a molten steel control device of continuous casting machine in the process of casting.
It could precisely adjust the molten steel flow rate that from ladle to continuous casting tundish to balance the inflows and outflows of molten steel, which makes it easier to control the continuous casting operation.
Now, slide nozzle system is widely used in ladle and tundish ladle in worldwide.

Application
Refractory sliding plates play a crucial and indispensable role in numerous high-temperature industrial fields such as metallurgy and casting. The following elaborates on their specific applications:
I. Steel Metallurgy Industry
1.Ladles: They have a refractory sliding plate at the bottom. After molten steel is tapped into the ladle from the converter, the plate closes to stop leakage. At the refining or casting station, it opens mechanically or hydraulically to let molten steel flow into equipment like a refining furnace or tundish at a set rate, reducing secondary oxidation and enhancing steel quality as it can open and close multiple times.
2.Tundishes: As a transition for molten steel from ladle to mold, the tundish's refractory sliding plate is vital. It adjusts the flow rate into the mold for continuous casting stability. In case of mold strand issues like breakout risk or slab quality problems, the relevant plate can be quickly closed to stop molten steel flow and ensure production line safety.
II. Non-ferrous Metal Metallurgy Industry
1.Copper Smelting: The refractory sliding plate controls copper liquid flow between smelting and refining/casting equipment. Given copper liquid's properties, the plate requires high corrosion resistance and sealing. Special materials help resist erosion and leakage, ensuring process continuity and product quality.
2.Aluminum Electrolysis: Although not used directly in the electrolytic cell, it's used after aluminum liquid purification. The plate controls the flow into casting machine molds, adapting to the low viscosity of aluminum liquid for smooth operation and precise control, improving production efficiency.
III. Casting Industry
1.Cast Iron Casting: The refractory sliding plate at the bottom of the casting ladle controls molten iron pouring. When ready, the operator opens it for even flow to avoid defects and can quickly close it during the batch for mold changes or suspension, adding flexibility.
2.Cast Steel Casting: Due to strict temperature and flow control needs, the refractory sliding plate is essential. It works in a high-temperature and high-pressure environment to ensure proper molten steel injection and can quickly switch tasks for multi-variety, small-batch production.
