S2 Integrated Slide Gate Set for Continuous Steel Casting Processes
The S2 ladle slide gate is a crucial device for controlling the flow of molten steel in the steel - making continuous casting process. It is designed to meet the specific requirements of different - sized ladles, ensuring the accurate regulation of molten steel flow and enhancing the stability and quality of the continuous casting process.
Structural Features
- Composition: The S2 ladle slide gate consists of a drive device, a mechanical part, and a refractory part. The mechanical part mainly includes a base, a bracket, a sliding trolley, a spring assembly, and a drive assembly. The refractory part includes upper and lower slide plates and a lower nozzle.
- Drive Mode: The sliding trolley of the mechanism can slide back and forth in the bracket driven by a hydraulic cylinder or other power sources. The spring assembly is used to establish a constant and uniform interfacial pressure on the active interface, ensuring a tight fit between the upper and lower slide plates during the sliding process and preventing molten steel leakage.
- Unique Design: It adopts a double - slide - plate structure. The upper and lower refractory slide plates have the same shape, size, and quality, and are centered and fixed in the slider of the frame by a special automatic centering device. This design ensures the accuracy and stability of the slide gate's operation. In addition, the slider can be swung outward, providing a convenient way to replace the slide plates, which can be completed in a short time.

Performance Characteristics of Refractory Materials
- High - Quality Materials: The slide plates of the S2 ladle slide gate are made of high - quality refractory materials such as alumina - carbon, alumina - zirconia - carbon, or magnesia - alumina - spinel, with phenolic resin as the binder. They are processed through vacuum pitch impregnation and medium - temperature treatment and can be divided into high - temperature - sintered and unburned products.
- Excellent Performance: The products have good thermal stability, erosion resistance to molten steel, corrosion resistance, and a long service life. The flatness of the sliding surface is ≤ 0.05mm, with high mechanical strength, high resistance to contamination by molten steel and slag, and excellent oxidation resistance.

Product Advantages
- Improved Production Efficiency: The main consumable components such as axles and track wheels are concentrated on the sliding trolley, which can be replaced online. When these components reach the end of their service life or are deformed, the sliding trolley can be replaced immediately without stopping the ladle, which does not affect the ladle's turnover and can improve the ladle's utilization rate. Moreover, the device is compact in design, which helps reduce the structural adjustment of the operating equipment in the on - site casting area.
- Reduced Labor Intensity: The S2 ladle slide gate is designed for easy operation and maintenance. The online replacement function of the refractory materials and the simple and practical structure of the sliding mechanism can effectively reduce the waiting time of empty ladles, significantly save production costs, and reduce labor intensity.
- Enhanced Safety and Reliability: The design of the mechanism and the performance of the refractory materials ensure the stable operation of the slide gate during the steel - casting process. The automatic centering device and the constant - pressure spring assembly can effectively prevent accidents such as molten steel leakage, providing reliable safety protection for the production process.

Below are some FAQ and answers about ladle and tundish flow control refractories:
Q: What are the requirements for refractories for ladle?
A: The requirements of refractories for ladle mainly include:
* high temperature resistance
* thermal shock resistance
* resistance to the erosion of the slag
* high temperature with sufficient mechanical strength
* the lining has a certain degree of expansion
Q:What are the reasons for the destruction of refractories for ladle?
A: The main causes of damage are as follows:
When the ladle transports high-temperature molten steel, the high-temperature molten steel and slag at about 1680ºC scour and erode it, especially in the slag line part, the scouring and erosion is more serious, and it is an important factor to decide the service life of the ladle.
LF and other extra-oven refining treatment on the unburnt brick damage is serious.
Q:What steel grades are different materials of slide plate bricks suitable for respectively?
A: Different materials of slide plate bricks are applicable to different steel grades. For example,
Al2O3-ZrO2-C slide gate plate can be used as ladle sliding gate plate due to its excellent erosion resistance and thermal shock stability, which can adapt to the casting of various steel grades, and ther are the following materilas based on customer's steel making condition: the MgO-C, MgO-Al-C, MgO-Al-C, MgO-Al-C, MgO-Al-C, MgO-Al-C, MgO-Al-C, MgO-Al-C, MgO-Al-C, and so on.
