Guoliang company owns three wholly-owned subsidiaries and one branch. It is a high-tech enterprise specializing in the integrated solution of refractories for high-temperature industry, providing customers with general contracting services and refractory products.
The Tundish Sliding Gate Plate is mainly used for ladle flow control in steel-making plants. It is an important functional component for safe operation of ladles. The sliding gate nozzle of the ladle is used to control the steel flow and the height of the liquid level of tundish. The sliding gate nozzle consists of inner nozzle, upper sliding gate plate, collect nozzle and lower sliding gate plate.
GUOLIANG tundish sliding gate plates are refractory flow-control components designed for continuous casting systems where reliable molten steel regulation, thermal stability and resistance to erosion are required. Installed in the tundish sliding gate system, the plate works together with the upper nozzle, lower nozzle and related gate mechanism to regulate or shut off molten steel flow during casting.
Our refractory sliding gate plates are available in different material systems, including Al₂O₃-C, MgO-Al₂O₃-C and Al₂O₃-ZrO₂-C compositions, allowing the plate design to be matched to different steel grades, casting conditions and service-life requirements.

A tundish slide gate plate operates under repeated exposure to high-temperature molten steel, rapid temperature changes and continuous flow erosion. Stable Tundish refractory performance is therefore essential for maintaining safe and consistent casting operations.
GUOLIANG sliding gate plates are designed to provide:
These properties make the refractory slide gate plate suitable for steel plants seeking stable tundish flow control and predictable refractory consumption.
The appropriate plate material and structure depend on the actual operating conditions of the continuous casting line. When selecting a tundish sliding gate refractory plate, buyers should consider:
Steel grade
Different steel compositions can create different chemical and erosion conditions. The refractory composition should therefore be selected according to the steel being cast.
Casting temperature
Higher operating temperatures increase thermal and chemical loads on the plate and should be considered when selecting the refractory grade.
Casting sequence and service life
For applications requiring longer casting sequences, higher resistance to erosion, cracking and bore enlargement may be required.
Sliding gate system
Plate dimensions, bore diameter, plate thickness and mounting configuration must match the existing tundish sliding gate mechanism.
Flow-control requirements
The bore design and plate configuration should correspond to the required molten steel flow rate and casting process.
GUOLIANG can manufacture custom tundish sliding gate plates according to drawings, dimensions, refractory specifications and operating conditions.
Our refractory sliding gate plates are primarily used in steelmaking and continuous casting applications, including:
For steel mills and refractory distributors, selecting the correct sliding gate plate for tundish helps maintain stable casting operation while reducing unexpected refractory failure and replacement frequency.
GUOLIANG supplies refractory products and integrated refractory solutions for high-temperature industries. For tundish applications, we can support customers with sliding gate plates and other compatible refractory components according to the requirements of steel plants and continuous casting systems.
Whether you are replacing an existing plate or sourcing refractory components for a new casting line, our technical team can assist with material selection, dimensional matching and product configuration.
A tundish sliding gate plate is a refractory component installed in a tundish sliding gate system to regulate, reduce or stop molten steel flow during continuous casting. The plate moves within the gate mechanism so that its bore can be aligned or partially closed to control steel flow.
Common material systems include alumina-carbon and alumina-zirconia-carbon refractories. GUOLIANG also provides different compositions and manufacturing processes according to operating conditions and required service performance.
Yes. Sliding gate plate dimensions, bore size, refractory composition and structural design can be produced according to the customer's drawing, existing gate system and casting requirements.
The selection should consider steel grade, casting temperature, required service life, gate mechanism, bore dimensions and current plate performance. Providing these operating details allows a more suitable refractory grade to be recommended.
Send us your sliding gate plate drawing, dimensions, steel grade and operating conditions. GUOLIANG can recommend a suitable refractory material and provide a quotation for standard or custom tundish sliding gate plates.
